Minerite sheets: what are they for?

Minerite slab is a multifunctional material, the scope of which is wide due to the composition that determines its characteristics. This is an ideal solution for ensuring fire safety properties during the construction of bathhouses, stoves, and other fire-hazardous objects. It functions well in a humid environment, is used for finishing facades, and is used in other areas. At the same time, installation is quite simple, the material is affordable. It is worth adding that it is produced in several color options.

Protection of bath walls

Those who have a summer house probably dream of or have already acquired a bathhouse. This building is classified as a fire hazard. It has a stove that allows you to heat the sauna to the desired temperature and steam. Sometimes people who built on their own did not think through the safety and security of the building well. Today there are many materials that will protect a wooden house from fire. One of them is a mineralite slab.

Protecting the walls of the bathhouse from the heat of the stove is not always required. For example, you can provide a distance between the wall and the stove, which will allow you to achieve fire safety without additional protection. The fact is that at some distance the IR rays emitted by the furnace begin to dissipate, which significantly reduces their impact on nearby surfaces.

The distance from the stove to the wall in the bathhouse varies depending on the type of stove:

0.32 m or more - the distance for a stone oven with quarter-brick masonry;
0.7 m or more is the required distance between the wall and the metal furnace lined with fireclay or brick from the inside;
1 m or more is a safe distance for an unlined metal furnace.

Finishing the stove in the bathhouse

Finishing the stove in the bathhouse is one of the painstaking stages of the entire construction, since it is important to maintain not only the aesthetics of the room, but also to combine this with operational safety.

Sauna stoves can be lined with different finishing materials:

Decorative plaster;
Fake diamond;
Ceramic tile;
Natural natural stone;
Brick;
Tiles, etc.

Any of these materials can be used as finishing for a stove in a bathhouse. You can do the finishing yourself, but first of all it is better to consult with specialists who will help you select the right materials and calculate the required quantity, depending on the type of stove (potbelly stove, Cossack stove), its size and the area of the room.

General information about minerite=»ltr»>

The material is a fairly new development in the construction industry and is essentially a cement-fiber board that is resistant to fire. You can often hear that mineralite is called fiber cement boards, which are equivalent definitions.

Minerite slabs are very popular for cladding buildings, as well as for cladding walls in baths and saunas, and shielding furnaces.

The main article about mineralite is here. We recommend that you first read it to understand the topic as a whole.

In saunas and steam baths, very hot streams occur near the stoves, so installing a mineralite slab is a very reasonable precaution. Specialized LV Sauna sheets are well suited for these purposes. The advantages of such stoves include safety for health, the absence of harmful emissions when used and exposed to high temperatures.

Surface preparation

First of all, you need to take care of preparing the stove surface. Before starting work, it is recommended to inspect the stove or fireplace. New brickwork does not require any special preparation other than cleaning it from dust. If the stove was plastered earlier, then you need to find out how thick the layer is. With a thickness of more than 1 cm, heat transfer decreases sharply. This plaster needs to be dismantled. When we are not talking about complete removal, only crumbling areas are scraped off. The entire surface of the stove is thoroughly cleaned. Cracks and sanded areas are rubbed with a lime-gypsum or lime-clay composition.

It is not always necessary to remove old paint. If it is not badly damaged, then it is enough to wipe off the dirt and dust. Then you can cover with a fresh layer. But first you need to find out what kind of coating was applied. The newly applied layer must match the old one. For example, chalk paint will not adhere to lime whitewash; it will simply crumble. And vice versa. If you don’t know for sure, then it’s better to scrape everything down to the brick. Before painting the stove, remove dust with a damp cloth. Then let the surface dry thoroughly.

There are no special tricks in how to paint a brick stove. Any untrained person can do this. Diluted or ready-made paints are simply applied with a brush in two or more layers. Painting a plastered stove is carried out only after the preparatory work has been completed, otherwise it will be ineffective. And it will have to be repeated after a very short period of time.

How to cover a brick oven in general? The following methods can be distinguished:

painting;
plaster;

varnish coating;
laying with heat-resistant ceramic tiles or tiles.

Now let’s take a closer look at how to paint a brick stove. Not every paint is suitable for this. It must meet certain characteristics. Good heat-resistant paint protects brickwork from aggressive environments and moisture. Here are some of the most common staining methods for brick:

lime whitening;
chalk painting;
coating with homemade paint;
painting with modern materials.

What it is?

Minerite was first introduced by a Finnish manufacturer who developed an improved technology for making cement slabs. The world owes the appearance of fiber cement to the Austrian Ludwig Hatschek, who developed this material at the end of the 19th century. The inventor spent 7 years experimenting by combining cellulose with cement and reinforcing fibers to create a hard, yet lightweight and practical heat-resistant material. Now, instead of mineral fibers, artificial fibers are used. With the help of dyes, the material is given a more attractive appearance, and its strength is enhanced by adding hardeners to the mixture. But the idea of fiber cement itself remains unchanged.

Compound:

70% is cement;
10% – cellulose;
20% – minerals.

The material under discussion has excellent performance, allowing it to be used in rooms where humidity levels are above normal and where there are critical temperature changes.

Withstands temperatures ranging from -80 to +150 C. At higher temperatures, the process of cellulose decomposition and damage to the board begins. The material demonstrates excellent performance in the following qualities.

Durability and long service life.
Moisture resistance and frost resistance.
Stable against alkalis and oxidation.
Environmental friendliness and safety.

How to paint a brick stove

There are no particular difficulties in painting a brick stove, so anyone can do it, even if they have not done it before.

Painting, especially for a newly plastered stove, occurs only after all preparatory work has been followed and completed, otherwise it will not be effective and will have to be repeated after a short period of time.

For coloring you will need the following equipment:

Container for coloring agent;
The coloring solution itself;
Convenient brush and roller.

Prepare a coloring solution and apply it in the required number of layers. It is recommended to apply the paint in two or three thin layers, using both a brush and a roller if possible. A brush can add texture to the outside of the fireplace, and a roller can distribute the paint evenly over the entire surface. If desired, patterns can be applied to the final layer of paint.

Minerite fastening

Minerite slabs for insulating the heating of the walls of the bath during its heating can be mounted in the following versions:

When the stove is located at a fairly large distance from the wall, the mineralite slab is attached directly to the wall;
When the stove is located at a distance of about 50 cm from the wall, the mineralite slab is attached to the wall with a gap of about 3 cm, with ceramic bushings installed in the gap between the slab and the wall;
With a small distance between the stove and the wall of the bathhouse, place two sheets of mineralite. In this case, one sheet of mineralite is fixed directly to the wall, and the second sheet is mounted at a distance from the first with a gap, which is determined by the length of the ceramic bushings.

In order to prevent breakage of mineralite slabs when heated from the furnace, when installing them, the holes for fastening with screws are made in the form of grooves.

When installing mineralite in a steam room on the walls, it is necessary to leave a gap between the lower edge of the mineralite and the floor of the bathhouse, which must be at least 30 mm. This is necessary in order to ensure air circulation between the mineralite and the wall and prevent the wall of the bathhouse from heating up, especially if the bathhouse is built of wooden beams.

When installing mineralite slabs on walls, inserts are installed in the gap between the floor and the slab, for example, from scraps of mineralite, which are removed after the walls of the bathhouse shrink, and the screws securing the slabs are finally tightened.

It is recommended to install mineralite slabs on a bath pipe, at a height of about 1 meter, which has thermal insulation with a casing.

When designing a new bathhouse building, the distance from the furnace wall, including pipes without insulation, to the mineralite sheet should not be less than 10.0 centimeters.

The material mineralite is a heat-resistant and environmentally friendly material.

More about some advantages of mineralite sheets =»ltr»>

Such fiber cement boards can be selected on the building materials market from a wide range of models, in various color variations. It will also not be difficult to trim the slab if necessary, if the specifics of the room or facade require it, because as you know, saunas and baths can be very small in area, and the facades are often made in elaborate shapes.

Even a beginner can install the slabs in question, because it all comes down to simple fixation on a special metal frame, and in some cases it is even possible to replace the metal structure with a wooden one.

Fire safety of mineralite - this characteristic is decisive when cladding various public organizations with increased fire safety requirements.

High strength, environmental friendliness and sound insulation parameters are important characteristics due to which mineralite sheets are used in the construction of government institutions, private houses and office buildings.

Nuances of choice

A wide variety of species often makes you doubt the correctness of your choice. To avoid problems and to avoid regretting your decision, you need to decide on the material that will protect the walls next to the stove, chimney or fireplace.

For finishing walls around stoves and in boiler rooms

Fireproof finishing of walls around furnaces and in boiler rooms is prescribed by fire safety rules and is mandatory.

Fire-resistant plasterboard panels can be used as a basis for cladding walls near the stove.
Using fireclay bricks and/or mortar, create fireproof protection in the form of a screen near the furnace. The surface inside the furnace is laid out (lined) with bricks, and cracks and cracks are sealed with mortar.
But the most effective protection for surfaces adjacent to fireplaces and stoves is made of stainless steel. Steel sheets are used to construct fireproof screens. They are mounted at a distance of 1-5 cm from the body of the stove or fireplace.
Thermal protection can be further increased by fiberglass laid under steel sheets.
Cast iron screens are also popular.
Basalt rolls and mats, flexible and lightweight, are also used for shielding stoves and fireplaces.
Terracotta or porcelain tiles are ideal for fire protection of boiler rooms, as well as baths. They do not deform or burn, and are also easy to maintain - they are easy to clean and wash. Due to their high decorative properties, they can also be used to decorate various surfaces.

For pipe

To avoid fire, chimney outlets must be reliably thermally insulated. For this purpose, mullite-silica boards and cardboard are used, which are excellent for processing. You can cut holes in them of any configuration for chimney pipes and other structural elements of stoves.

For the bath

The walls of the baths are finished with heat-resistant materials so that they have fire-resistant properties. For this use:

“pie” made of a metal reflective coating and a heat-insulating gasket;
superizol;
fire-resistant plasterboard;
glass magnesite;
minerite;
terracotta tiles.

Fire protection for sauna stoves is also provided by products made from foamed vermiculite. For the layer between the first rows of the stove masonry and the wooden floor, vermiculite boards are preferable, since they are stronger than cardboard.

For the fireplace

The main product used for facing the fireplace, along with fire-resistant plasterboard, is fire-resistant ceramics:

terracotta tiles or majolica as its variety;
tiles;
clinker tiles;
porcelain stoneware

All of them are moisture resistant and resistant to temperature changes. Choose tiles marked A - they are of higher quality than tiles marked B.

Advantages of mineralite

Having made the insulation with mineralite, you will forget about replacing them for a long time. They serve well and properly.
The panels do not burn or ignite. This fiber cement board meets the most stringent fire safety requirements.
Minerite is considered a universal material. It can be used not only for insulation, but also for decorative finishing.
Installation of the plates is extremely simple.
You can do everything yourself without resorting to outside help.

A mineralite slab for a bath, like any other material, in addition to its undeniable advantages, also has disadvantages. And most buyers note only one thing - the unpresentable appearance of some types of such panels. If you choose more decorative specimens, they will cost a little more.

Protective screens

Speaking about fire safety in the bathhouse, first of all it is worth highlighting the protective screens that insulate the stove in the bathhouse from the walls.

On the construction market, the most common metal protective screens are made of steel or cast iron. Many manufacturers of iron furnaces provide thermal insulation for their products, providing them with special casings.

Choosing protective screens is quite simple, because depending on the side of the furnace to be insulated, you can purchase a front or side panel. Installing such screens will also not cause difficulties, because the manufacturer provides special legs that can be easily attached to the floor.

Effective methods of protection

Among the most effective methods of protection against exposure to high temperatures and heat are screens made of:

mineral wool
basalt wool
foam glass
glass wool
vermiculite
drywall
minerite
of stainless steel

Using the materials listed above, as a rule, so-called screens are created - surfaces of a certain width, length and thickness, installed in close proximity to the heating product and sections of the chimney.

Applying paint

Painting fireplaces requires preparation, just like any other construction work.
First you need to make sure that you have purchased exactly the composition you need. You also need to prepare the following tools:

soft cloth;
sandpaper;
water;
brush;
roller;
copper sulfate solution;
sulfuric acid solution;
spray.

First, prepare the surface that will be painted. It is cleaned of dust and dirt. Metal parts are cleaned with fine sandpaper. Be sure to remove greasy stains with a soft cloth soaked in a solution of water and salt. Soot can be easily removed with a solution of hydrochloric acid, and rust with a 10% mixture of copper sulfate.

It is recommended to apply the paint to a slightly warm surface using a brush, roller or spray - whichever is more convenient. In total, you need to make 2-3 layers, each of them should be allowed to dry thoroughly before applying the next one. The fireplace must be allowed to dry for several days; it cannot be used until the paint has completely hardened.

Areas of application

The versatility of mineralite justifies its demand for various types of work.

Fiber cement boards are suitable for installing screens around hot stoves, hot fireplaces and heat-emitting equipment in saunas.
Fire-resistant partitions are built from mineralite slabs, dividing the area into fire zones, equipping a safe exit during evacuation. Using a certain technology, walls, ceilings, chimney systems, and ventilation ducts are sewn up in fire hazardous areas.
High moisture resistance allows the use of this material where there is excessive dampness and humidity (showers, swimming pools). In this case, additional waterproofing treatment (aqua blocks) is not required.
Can be used as a base for facing tiles and other waterproof materials for final finishing.
Thermal insulation and excellent adaptation of the material to temperature changes suggest its use for cladding interior spaces and exterior walls of buildings, including loggias and balconies.
Serve as a smooth, waterproof base under wood stoves, wall and floor tiles.

With moderate weight, the slabs are characterized by increased strength, impact resistance and durability. It is also important that the components of mineralite contribute to the self-cleaning of the surface of the slab. And in addition to excellent structural properties, the material is endowed with aesthetic capabilities. The slabs are produced in different color variations. A variety of decorative colors on the front part of the coating allows you to cover facades with mineralite during the reconstruction and construction of residential and administrative buildings.

What are heat-resistant paints for?

Thermal paints are able to protect materials at high temperatures. Organosilicon-based compositions are good. They are also used when painting heat exchange equipment or heating equipment, the temperature of which is higher than that of the furnace walls.

Such materials serve not only for decoration, but also to increase the functionality of the stoves, promoting a smooth temperature distribution throughout the structure, thereby avoiding overheating. This is especially important for metal welds that begin to melt when exposed to heat. In addition, the paint serves as protection against released salt solutions, petroleum products, as well as high humidity, while maintaining vapor permeability.

Types and sizes

There are not many varieties of mineralite, but they exist, which makes it possible to isolate the material for a specific area of application. For example, decorative mineralite , labeled “Pastel”, has a polished smooth surface and is used for finishing facades. The “PC” variety, more than other options, is represented by a wide variety of colors. Also suitable for facade and interior work.

The variety labeled “HD” is most often used in its pure form, where aesthetics are not so important. Its price is lower, but its technical characteristics are in no way inferior in quality to other varieties.

Minerite size

In addition, the “HD” series reserves the right for the buyer to independently choose the paint and apply it if necessary. The main thing to remember is that if you are going to use the material in finishing areas near flammable areas, it is important to use fire-resistant types of paints.

The “VZ” variety is aimed at facade work, and the main goal is to protect the building from moisture and wind. The dimensions and thickness of products are individual and, basically, they depend on the manufacturer.

Facade finishing is characterized by slabs measuring 60 by 30 cm, with a slab thickness of 8 mm. A mineralite slab 6 mm thick is also suitable for interior work Its sizes are individual and can have different shapes, including mineralite like a brick. On average, the dimensions of the panels can be 60 by 120 cm.

For regiments

Shelves are an indispensable attribute of a steam room. True, they are Finnish and Russian, but for some reason they don’t talk about this very often.

The difference between the Finnish and Russian regiments is only in the design, but the material for the regiments in both bathhouses is the same.

ADVICE! Use cheaper lumber from softwood to create the frame of the shelves, and make the shelves themselves from hardwood, for example, linden, aspen, ash, abasha, etc.

Planken is often used as a material to create shelf seats in a bathhouse - it is loved for its smoothed ribs. Although this is, in principle, a façade material.

Linden shelf, Extra grade

Characteristics and properties

Minerite slabs are available for sale in two sizes: 1.2 and 3.6 m long, with a width of 45 cm and 1.5 m, respectively. The stove weighs about 25 kg. The material is imported to Russia from Europe and its price is affected by the euro exchange rate. Minerite slab is an expensive construction resource, but the availability of domestic analogues allows you to save a little. Russian-made fiber cement panels not only do not compete with foreign ones in terms of technical characteristics, but also surpass them in a number of characteristics.

The products have the appropriate technical documentation and a certificate that allows use in construction in the Russian Federation.

Minerite is characterized by the following properties.

High strength and impact resistance. Under the influence of loads, the surface does not deform.
Absolute fire resistance. The material remains virtually unchanged at temperatures reaching 150 degrees.
The panels do not deteriorate in a humid environment. Thanks to water repellents, the board does not absorb moisture, which quickly evaporates from the surface of the material.
Tolerates temperature fluctuations well.
Mold resistance.
Stable against alkali and acids.
Good sound insulation.
Clean material in an environmental sense.
Guarantees a long service life.

These characteristics are among the advantages of mineralite. But, like all building materials, it has weaknesses. In this case, the disadvantage is fragility. Therefore, it is important to cut and cut it into fragments with extreme care. Another disadvantage is thermal conductivity, which can be solved by taking certain measures during the installation process.

Minerite slab for a bath: technical characteristics

Main technical characteristics:

High strength, when exposed to loads, the surface is virtually not deformed, the panels are inherently impact resistant.
It has absolute fire resistance, it is not subject to combustion or ignition.
The panels have proven themselves to work well in a humid atmosphere, without deteriorating their strength parameters. This is due to the fact that the composition contains water repellents - components that protect the slab from absorbing moisture and allowing it to evaporate. In addition, mineralite successfully tolerates temperature changes.
Minerite slab is highly heat resistant. It does not change the original characteristics, operating within the temperature range from minus 80° to + 150°.
The cement component ensures the material’s resistance to mold and mildew and prevents rotting processes.
Stability to chemical reagents in the form of alkalis and acids is noted.
It has soundproofing properties, is an environmentally friendly building material, and has a long service life.
The weight of one plate does not exceed 26 kg. This makes installation easier.
The size of the slabs will fit any bathhouse. Length ranges from 1200 to 3600 mm, width – from 450 to 1500 mm, thickness – no more than 6 mm.
Eco-friendly composition.
Minerite slab differs from many other materials in its ability to self-clean.

These characteristics and properties of mineralite are considered the advantages of a building material. But its fragility is a weak link, therefore cutting and cutting into blanks must be done extremely carefully. You can cut mineralite with a regular hacksaw, grinder, jigsaw, or other tools, which is very convenient.

How to paint a brick stove

There are several materials that can be used for painting:

Enamel. It is characterized by good strength, resistance to moisture, excellent interaction with other materials, increased durability - it can withstand up to 200 cycles of sudden temperature changes. There is also a small drawback - the choice of enamels colors is very scarce.
Oil paint for a brick stove. Among all the options, this is one of the best. The main advantages: a variety of colors, the ability to withstand temperatures up to 600°C, guaranteed protection of bricks from oxidation, increased resistance, durability - lasts up to 10 years of operation with the stove. Oil paint is easy to apply and does not require additional priming of the exterior. There are also disadvantages: not a very pleasant smell, the presence of toxic substances in the composition, longer drying compared to other options.
Drying oil. Coating with natural drying oil cannot change the original color of the brick, only darken its shade.
Heat-resistant varnish. Its main advantage is the ability to increase the technical characteristics of the strength of bricks. After applying the varnish, a transparent shiny layer remains on the surface. A special feature of using varnish is the ability to add dry gouache to obtain the desired color and shade.

Professional installation of bath equipment and insulation

Any furnace equipment is a source of fire hazard, so the installation of fires and installation of insulating materials must be carried out by professionals. Insulating materials vary, and not all are suitable for contact with very hot surfaces. Even mineralite, although it is a fire-resistant material, with increased exposure to high temperatures and fire can begin to melt or char, creating a risk of fire. Minerite is suitable for insulation purposes, but it should be installed with knowledge of safe distances, maximum operating temperatures, equipment heating temperatures, and other nuances. This material is often installed together with other insulation solutions to achieve the highest level of safety.

Our specialists have impressive work experience and unique knowledge, which is recommended for anyone who is organizing their bathhouse, home, or installing a heating product. The company’s specialists will prepare an individual plan for installing insulation and carry out a range of installation works with the selected insulation material within a prompt time frame.

Attention! Only professional installation of mineralite and other insulating solutions can be a good guarantee of fire safety, health and property.

Installation of slabs on a wooden wall can be roughly divided into the following stages:

Installation of brackets on a wall requiring insulation (no longer than the thickness of the insulation board itself)
Laying preliminary insulation (for example, basalt wool) with dowel fastening - umbrellas
Installation of a frame - metal profiles placed vertically and horizontally to obtain a conditional rectangle, square, or other chosen shape
The insulating material itself is mounted directly onto the resulting frame. For slab thicknesses up to 15 mm, you can use simple self-tapping screws for fastening. When the slab thickness is more than 15 mm, clamps are used.
The joints should be carefully treated with heat-resistant sealant
If there is a corner, it is recommended to cover it with a metal profile

Tip: it is recommended to use a special sealing tape between the frame and the mineralite in cases where self-tapping screws are used for installation.

Overview of species

Windproof. They are used for finishing facades and construction using frame technology, when the slabs act as a structural material and serve as wind and hydraulic protection. Minerite sheets of the VZ modification are produced in sheets in the following sizes: 900x2700 mm; 1200x2700 mm.

Construction, HD modifications. A universal material suitable for cladding buildings inside and out. Such cladding does not deteriorate due to critical changes in temperature and humidity. The panels are distinguished by high strength. Sheet thickness is 3.2-10 mm, determined by purpose. The most popular slabs with a thickness of 8 mm.

Flat PC panels for mounting on facades. This type is based on HD modification slabs. The material is primed on both sides, and a durable acrylic layer is applied to the front part of the panel. Colored panels are presented in four versions, differing in size.

Possible thickness 6 or 10 mm.

“Pastel” facade slabs with a hydrophobic coating and a smooth painted surface.

Heat-stable, fire-resistant sheets. Designed for installation on wall and ceiling structures to protect them from the influence of heat, for decorative lining of fireplaces, etc.

Decorative. Manufacturers produce products with a textured surface that imitates various finishing materials. For example, mineralite “like a stone” is a very good option for arranging living spaces and steam complexes, for creating conditions for fire safety, sound insulation with insulation and visual aesthetics. Along with the declared strength, they look very decent. Many consumers prefer colored slabs for interior work, despite the fact that it is somewhat more expensive. The color of the slabs comes in different shades, depending on the brand of cement used.

Which method is better to choose?

The finishing of the wall from the stove for different types and sizes of baths is used in different shapes and materials. The main thing is to ensure the fire safety of your steam room and protect the walls from deformation at high heating temperatures.

Otherwise, everything depends on the capabilities and desires of the steam room owners. You can use heat-resistant tiles or expensive tiles, or you can simply cover the walls and ceiling with mineral wool and a layer of metal foil. By leveling the walls with sheets of plasterboard with surfaces not exposed to open fire, you can paint the steam room with heat-resistant paint using Minerita.

If the bathhouse is large, you may not need to perform this work if the conditions of SNIP and fire safety are met. By making the concrete base larger in size than the stove and maintaining a gap of 1 m to the walls, you can safely use the heater and enjoy the steam

In any case, it is important to take care of safety and then your sauna will serve you for a long time

Price

Minerite , or also called fiber cement board, is sold in any hardware store. Compared to other analogues, mineralite is inexpensive. For example, a thermal insulating product for protecting wooden surfaces from fire, measuring 1.2 m by 0.6 m, with a wall thickness of 8 mm, will cost the end buyer about 1,100 rubles.

That is, for the wall in the bathhouse you will need about 4 slabs for the wall, and 2 slabs for the ceiling, which will be about 6,600 rubles. Do not forget about the basalt material, which is attached as a substrate to the wall. Its cost is about 500 rubles per square meter.

For 1100 you will get a regular stove. Options for wood, stone or brick will be more expensive. For example, Flamma's product, Design A022, of the same dimensions as the previous slab, will cost about 2,500 thousand.

This will be a completely non-flammable stove, class A1, with an area of application in baths and saunas for both electric stoves and wood-burning stoves. The material can easily withstand temperatures of 180 degrees.

Installation of mineralite

Plates from the manufacturer AquaBlock have a specialized focus. They are suitable for equipping bathrooms and restrooms in wooden houses. The price of mineralite per square meter is 800 rubles. As for the dimensions, the stove has dimensions of 2.6 by 1.2 meters. It is aimed at hiding unevenness and protecting the wood from moisture and fire.

The market is full of offers, so everyone will find a finishing option with suitable characteristics. Don't forget about related products, such as basalt wool. Also use wind protection and proper guides. Below is a video in which a mineralite fire resistance test is performed.

Why do you need to paint?

One of the modern fashion trends is the presence of decorative elements made of natural stone or brick in the interior. Many designers use the natural look and texture of the material. It looks especially beautiful when building and lining fireplaces and stoves, favorably combining the rough appearance of brickwork and live flames, creating an atmosphere of home comfort.

Simple red brick for masonry is attractive at an affordable price, but its quality often leaves much to be desired, in which case they resort to painting or plastering. If you spend money and purchase a special facing option, it is enough to treat it with a special varnish, which will add richness and expressiveness to the appearance. Reasons to paint a red brick fireplace:

erosion protection;
hiding minor defects in masonry and material;
additional strengthening of the structure;
aesthetic appearance and rich color.

General recommendations

An experienced craftsman will advise that it is important not only to install a fireplace or stove, adhering to the technology, but also to cover it correctly, then the structure will serve for many years and delight you with warmth and a beautiful appearance. It is advised to adhere to the following principles:. The building should be painted when it is warm.

The building should be painted when it is warm.

start painting or cladding several months after installation (up to a year), waiting until it has completely dried;
select a special coating that can withstand high temperatures;
pre-treat the surface, remove dust, wash and dry;
Apply paint to a warm (non-hot) surface in 2 or even 3 layers.

What paints are used to cover a brick fireplace?

To treat a surface that is constantly exposed to high temperatures, it is necessary to carefully select a coating. To preserve the natural look, varnishes are used, and to decoratively change the color or hide imperfections in the masonry, buy paint in the store. Folk dyes for stoves based on lime, clay or chalk have long been known, which save the budget and add a touch of antiquity to the interior.

An owner who wants to cover brickwork must remember that ordinary oil paint cannot be used; it delaminates when heated, producing fumes and an unpleasant odor that pose a danger to human health. Most manufacturers produce special products that are labeled as “heat resistant.” These products are intended for professional or DIY surface treatment. The maximum permissible temperature is indicated on the product packaging.

Grandma's painting methods

lime;
chalk solution;
clay;
homemade coloring agent.

Chalk mixture

To prepare a chalk solution that is safe to paint a fireplace, take crumbly chalk and fill it with water. Leave for several hours until dissolved. At the same time, prepare glue (carpentry or casein) at the rate of 100 grams per bucket of solution. The chalk suspension is stirred to the consistency of sour cream, the adhesive component is introduced and thoroughly mixed again. Brilliant blue or manganese are used to change color; artificial dyes that are used at high temperatures are also allowed. Paint with a roller or stiff brush. The second layer is applied only after the previous one has completely dried.

Lime for painting

Lime solution is one of the most popular old-fashioned methods of covering not only stoves, but also the walls of the house; it allows you to cheaply process the coating to achieve the desired color and protect against pests. For 1 kg of quicklime take 1.5 liters of water. Colors are achieved using the same methods as with chalk. For application, use a wide brush or roller; several layers can be applied one after another without waiting for drying.

other methods

The following folk methods of covering fireplaces or stoves are known:

Thin clay solution. It is affordable, but does not allow you to experiment with color; it is suitable for lovers of natural finishes.
Homemade paints: mix PF-283 glue with solvent or turpentine.

Processing stages

It is important to follow the stages of work to achieve the expected result. Remnants of the previous coating are first removed

Apply the solution to a previously prepared surface, using only products selected for the appropriate temperature. Each subsequent layer is applied after the previous one has dried. You can light the fireplace 2-3 days after treatment so that the paint dries evenly and does not flake or fade.

Comparison with other materials

When thinking about how best to choose a material, you need to start from specific tasks. Let’s say that when building a bathhouse, the primary issue is the thermal insulation of the walls from a high-temperature furnace. It is completely unacceptable to use asbestos for this purpose, since it is unsafe; tin panels, bricks and steel sheets are obsolete materials. A cheaper analogue of mineralite can be called magnesite.

This is a natural material that has undergone technological processing and serves in high temperature conditions, which are critical for analogues. Magnesite slabs are easy to cut and fasten; they do not emit harmful substances when heated. All indicators are similar to mineralite, but fiber cement boards are in the lead as a more modern material. For example, fire-resistant panels produced using the Finnish LTM Flamma 9 mm technology are an excellent choice for a bathhouse in terms of safety, durability and aesthetics.

Of course, you can replace them with heat-intensive and affordable bricks. Fireclay and building bricks are equally suitable for thermal protection. But its disadvantage lies in the fact that you have to make a solution, and the structures made from it are very heavy. In addition, the roof and ceiling cannot be protected with bricks. The technology for producing mineralite was borrowed from the Finns by Russian and Japanese manufacturers. Many produce material using Finnish equipment.

Analogues are not inferior to the original in quality, and some are much more attractive in cost.

“Nichiha” is fiber cement siding from a high-quality Japanese brand. It differs from Flamma in its brick-like textured structure and higher cost. In the European part of Russia it is much less common than in the vastness of the Far East. Flamma-minerite, accordingly, is more in demand in the west of the Russian Federation. The NICHIHA product line includes about 700 options for panels of complex design, a selection of textures and colors to realize any ideas. At the same time, the panels do not require regular maintenance, are able to clean themselves and maintain their ideal appearance for a long time.

“Faspan Antiflame” is distinguished by its “ceremonial” appearance and persistent white color interspersed with mica. This makes it stand out from the bulk of unattractive sheets on the construction market. Thanks to the beautiful texture, the buyer can save on finishing.

CSP (cement particle board) is a more budget option. Loses to mineralite in terms of external qualities. Fiber cement siding is a worthy competitor to its wooden counterpart, since the minimum service life of mineralite is 50 years. The slabs can be selected according to size and shape, and most importantly, this will cost less than using wooden materials.

The difference between mineralite board and other building materials is its safe composition. At the same time, mineralite is endowed with the ability of self-purification. Thanks to innovative production technologies, it does not emit harmful components when heated. Such insulation can be confidently used for thermal insulation of steam rooms. Thanks to this, it will be possible to create a completely harmless microclimate in the room.

Instructions for Painting a Brick Fireplace

Tools and materials needed: sandpaper, vacuum cleaner, construction fabric, construction tape, brick primer, brush and roller, paint tray, latex paint.

Choosing a color for the fireplace

Select the color you would like to paint the fireplace, decorative hearth fence, painted in the main color. If you're overwhelmed by the wide range of different colors available, it's time to get inspired and get creative. You can choose from the existing colors of the room, for example, the color of fabric, curtains, upholstery or pillows, or any other favorite color.

Preparation of the working surface - brickwork

The next step is to prepare the work surface, and for this you will need to prepare and clean the brick. Use sandpaper to sand the surface of your brick fireplace. This solution will help you remove the grout chunks, after which you need to use a vacuum cleaner to get rid of the dust and dirt. Use a bucket of water and soap to clean any stains or grease from the surface of the brick, then allow your fireplace's brickwork to dry. Repeat the vacuum cleaner.

Protection of third-party surfaces

Continue with your prep work, which includes covering any areas or objects you don't want painted with painter's tape and fabric.

This is a very important decision that will later save a lot of time that would otherwise be spent dealing with errors such as accidental paint drops.

Primer work

Find a primer that can be used for masonry projects. You can use a thick layer of primer (up to one inch) to cover the surface, and then use a brush to touch up difficult areas. Let the primer dry. If you plan to use bright colors that are different from the original paint or original brick color, you can use a tinting primer in the intended color to make the new paint work easier.

Painting a brick fireplace

Now you need to start the actual coloring. Use your chosen paint color. Use only high quality latex paint and begin painting the brickwork of your fireplace using a roller or brush. For complete, long-lasting paint coverage, you may want to consider applying two or three coats of paint. The fact is that the porous surface of the brick absorbs paint very effectively, which can result in defects on the surface of the masonry if you only applied one layer of paint.

Tips and warnings

Choose inexpensive brushes to paint your brick fireplace. The rough and porous surface of the brick will destroy the bristles of any, even the most expensive brushes. Don't limit yourself to a construction project that only you can control. You can paint your fireplace one solid color, or get creative and create a layered look by lightening and mixing different colors for added impact. If you're planning on highlighting a brick fireplace as the focal point of the room, it's worth painting the fireplace a different color from what's featured on the room's walls.

On the other hand, if you want to draw attention around the fireplace, paint it a color similar to the walls.

Minerite composition

Minerite is the same fiber cement board, the composition of which determines the area of its purpose. The base is formed from cement (up to 70%), cellulose, mineral components, and also contains synthetic components and other additives.

It is characteristic that the composition does not contain asbestos, which makes the material safe for others when heated sufficiently. It does not emit components hazardous to health, which expands the range of use of the building material.

What is minerite?

Minerite is a product that can hardly be called a building material. It does not have super strength, which would allow it to be used as elements of a supporting structure. But, at the same time, it is based on a cement mixture, which means it gets stronger every day, at least 50 years of complete drying at the time of production.

Practice shows that many people choose this product due to its non-flammability properties. Thus, it is relevant for baths and saunas, where a stove is installed near the tree or heating elements pass through.

Here, refractory mineralite is a slab designed to operate within a temperature range of -100 to 180 degrees Celsius, which expands the range of use in different areas of the world.

Fireproof mineralite plate

When heated, the surface of the plate does not react in any way, including cracking, deforming and losing its properties. When used in a steam room, mineralite slabs easily withstand moisture, even when they are heated to the limit.

But the area of application described above is not the only one. Due to its lightness and strength, resistance to moisture, mineralite can be used in cladding the facades of buildings.

The latter is facilitated by modern production technologies, which make it possible to paint in different shades. The installation method can be different and, depending on the purpose, the material can be easily attached to both vertical and horizontal surfaces. Ceiling mounting is allowed.

Floor

The insulation process should begin from the floor. There are two floor design options:

leaking;
leak-proof.

Solid

Thermal insulation of non-leaking (solid) floors is carried out by analogy with floor insulation along joists. A subfloor is laid along the floor beams, and mineral wool slabs are laid. A layer of waterproofing must be laid on top.

Leaking

Leaky floors require a slightly different approach. They must allow water to pass through, which spills onto the floor in the washing compartment or in the steam room combined with the washing room. At the same time, they should not let the cold from the ground into the room.

The most common option is a heated floor on the ground with an insulating layer of polystyrene foam or EPS. In cross-section, the structure consists of the following layers:

foundation soil;
compacted sand layer;
gravel drainage bedding;
rough screed;
insulation;
waterproofing;
reinforcing mesh;
finishing screed.

Removable antiseptic wooden ladders are laid on top of the finishing screed, acting as a finishing floor. After all procedures are completed, the ladders in the bathhouse are raised and dried.

Technical characteristics of mineralite

This board is quite lightweight and yet highly durable. In addition, the material is environmentally friendly, which is due to the widespread use of mineralite in construction. When heated, the stove is not capable of releasing harmful substances. The material in question perfectly absorbs sound.

The product has increased resistance to external environmental factors. Such slabs are not exposed to sudden temperature changes and changes in air humidity.

Such slabs have excellent waterproofing properties - which is why they are increasingly used in rooms where air humidity is very high.

It is also often used in saunas and bathhouses to insulate stoves: special fire-resistant partitions are erected, and slabs are also mounted on walls and ceilings.

Prevention of poisoning

Today, the answer to the question of whether asbestos is harmful to health is already obvious and beyond any doubt.

Therefore, it is extremely important to remember that the use of amphibole mineral is strictly prohibited under any circumstances. When using the more common chrysotile, the following instructions must be observed:

when coming into contact with asbestos materials, use protective equipment;
waste and dust should be stored in a sealed container, then disposed of using a special technology;
use only dense products: they should not crumble;
the mineral cannot be sprayed in the air;
periodically monitor the permissible level of asbestos fibers in the production area;
undergo regular medical examination.

The chemical composition of sheet asbestos is identical to the material discovered in the Urals. Having decided to remove the asbestos roof, you should prepare a change of clothes. Upon completion of all work, it is better to dispose of it. Some builders recommend lightly moistening the slate with plain water on the eve of dismantling. In this case, asbestos dust will not be able to rise into the air.

Today, asbestos-cement slabs are practically not used in construction. If possible, they should definitely be replaced with a building material of similar characteristics, but safer. Panels containing asbestos continually release harmful microfibers into the environment. And people nearby will inhale them every day.

Application

The scope of application is extensive and covers the sphere of private and capital construction. Let's look at the main areas:

Instead of asbestos. Asbestos releases substances harmful to people that can make people feel worse. Therefore, when exposed to high temperatures, mineralite is used. And these are baths, saunas, Russian stoves, industrial premises where a high fire safety limit is required. By the way, the “LV” series, which was not previously mentioned, is suitable for saunas. It is lightweight, has many color options, does not burn and can withstand temperatures up to 180 degrees Celsius. The material showed itself to be absolutely normal in matters of zoning application.
Where it is damp and humid. These can be basements and semi-basements, washing rooms in bathhouses, bathrooms, rooms near swimming pools. Minerite for baths not only does not deteriorate from moisture and protects the surface of load-bearing walls from destruction, but also prevents the formation of fungus and mold. At the same time, if you have a wooden house, then the surface of the walls can be covered with mineralite, and tiles and porcelain stoneware can be laid on it without additional insulation from water. You can do the same in the kitchen, and then hang wallpaper.

Protection of a chimney in a bathhouse with mineralite

The scope of application of such finishing options is so diverse that it covers the private sphere and permanent buildings. For example, mineralite is used to decorate the exterior facades of houses, to create safety zones inside baths and saunas, even in houses where there are full-fledged fireplaces. In particular, mineralite can be used for finishing utility rooms, loggias, balconies and other places. The variety with the “RK marking” is suitable for finishing facades.

Applying paint to metal surfaces

First, the metal elements are cleaned with sandpaper, and the walls of the fireplace are cleaned of dust with a damp cloth. Metal dampers are treated with a 5% sulfuric acid solution and a bristle brush. It is necessary to wear gloves when working with acid. The remaining composition is washed off with a soap solution - first with a cloth, and then with a rag.

If the hearth is not built very correctly (for example, the masonry is uneven), then the surface must be plastered with lime-gypsum mortar in several layers, after preheating the oven to 150 degrees.

When painting, it is important to remember the safety rules: work with gloves and only in a well-ventilated area. It is also necessary to avoid contact of paint and other products with skin or eyes.

An important stage of decorative cladding is painting a brick fireplace. Even if a special facing material is chosen during construction, which does not require subsequent putty for durability and a beautiful appearance, it is important to choose the right coating

Properly selected paint or varnish will protect the bricks from destruction and add aesthetics to their appearance.
