Painting the outside of a log house, what to paint it with, choice of products and materials, preparation, processing

Over the years, material such as wood darkens. And a house built on its basis also loses its initially presentable appearance. Therefore, it is not surprising that many residents of old log houses are looking for a good coloring agent in order to restore the former beauty of their home. After all, the choice of paint for log houses is not easy to make and any coloring composition will not work. So, how can you paint a log house that has lost its beauty over time?

Choosing the right paint

Wood is a building material of natural origin and, unlike man-made brick and concrete, it reacts much more strongly to air humidity, wind, temperature fluctuations and solar radiation. Wood without bark can rot, burn out and become a haven for all kinds of molds and wood-boring beetles.

The factor that determines the service life and external decorative qualities of a log house is the choice of coating. Paints or impregnations for treating wooden façade walls are used to preserve wooden elements and must meet certain requirements:

Create a surface protective layer that protects the wood from rain, snow and atmospheric moisture. Be frost-resistant (not destroyed by cyclical temperature changes).
Have UV protection . Direct sunlight causes unprotected wood to change color (tanning effect) and lose its attractiveness.
Have good adhesion (adhesion to the plane of the facade) and absorbency (important when processing with impregnation; penetration depth is indicated in the instructions for the product).

Demonstrate lack of moisture absorption .
Be environmentally friendly . A parameter that is especially relevant for a log bathhouse.
Don't lose your attractiveness. Varnish and acrylic compositions should not lose their original gloss. Paints must retain their original color .
Contain fire retardant and antiseptic additives. Modern dyes are capable of maintaining the safety of a wooden structure.
Be abrasion resistant .

The market offers a wide range of products suitable for painting the facade of timber and log houses. Modern coatings make it possible to preserve and emphasize the naturalness of the facade material or completely hide it under a protective layer. When deciding how to paint the exterior of a log house, owners give preference to proven, certified products. In practice, several types of coatings are used, the characteristics of which are useful to have an idea of.

Antiseptic impregnations (waxes, stains) and varnishes

Liquid antiseptic impregnations for wooden surfaces penetrate the wood structure to a depth of 0.5-1 cm and create a barrier to all threats, natural and weather. There are two types of antiseptics on sale:

Wax . Water-based wax is perfectly absorbed into wood, without creating a continuous film and maintaining its breathable properties. When finishing the exterior of a log house, a colorless or glazing (translucent) composition is used, creating a mother-of-pearl effect or an additional shade on the surface. Gives the facade water-repellent properties, leaving the natural structure visible.
Wood stain . The composition is a tinting (impregnating) agent that colors the facade and protects it from biological contamination. The coating is short-lived, so a varnish is applied on top, which can extend the life of the stain and enhance its protective properties.

Varnishes (colorless or colored) are a proven, reliable means of protecting facades. Both options do not hide the natural texture of the wood; colored varnish can highlight its color. Varnishes, glazing impregnations and wax are used for painting not only outside, but also inside homes, where non-toxicity and external decorativeness are especially important.

Acrylic (acrylate) paints

Water-based acrylic paints for treating the external walls of a log house are considered the most acceptable, high-quality option with many advantages:

contain solvents ;
dry quickly and form a durable, vapor-permeable film;
protect the wooden facade from ultraviolet radiation ;
durable (resistant to weather vagaries);
They retain their original color and shine for a long time (7-8 years) .

The construction market offers several types of paints:

Water-based acrylic paints . It is a water-acrylic emulsion (composition of two immiscible elements). After application to a wooden wall, the water evaporates, leaving a thin film layer with attractive properties on the surface. The paint does not have a strong odor, is flexible enough not to deteriorate under the influence of low temperatures, is vapor permeable (allows the wood to breathe) and at the same time waterproofs the facade.
Water-based latex paints . They also contain acrylic resins, and therefore they are elastic, do not fade under solar ultraviolet radiation and are resistant to abrasion. Synthetic latex in the paint makes the surface silky in appearance. This paint is used when processing facades, window and door openings, and fences.

Alkyd compositions . They are produced on the basis of alkyd resins, which remain in the surface layer of wood to form a protective glossy layer. This paint fades quickly, but is resistant to negative temperatures and high humidity; it is often used to paint doors and window frames.

The disadvantage of acrylic dyes is their fairly high price. When painting log walls, they can be replaced with less expensive acrylate paints and aqualacs based on acrylate resins and dispersions, which reduce costs. These compositions have similar characteristics, they are safe and beautiful, but are designed for a shorter service life.

Oil based paint

Oil paint for a log house, used externally, is a familiar and fairly common method of painting. Despite its modest consumer qualities, it continues to be used; more often for painting fences than residential buildings.

Why and from what to protect wood

Wood is a building material that, unlike concrete and brick, is more susceptible to environmental influences. Rain, dangerous insects, and high air humidity have an adverse effect on wood from which the bark has been removed. Therefore, log houses or wooden baths require mandatory covering.

Stages of preparing a log house for painting

In order for the paint layer to lay smoothly and beautifully, and for the coating of wooden walls to satisfy the quality throughout the guaranteed service life, it is necessary to consistently prepare the facade, adhering to the technology. Before the exterior of a wooden house is processed, a number of preparatory works are carried out:

Grinding . It is mandatory even for new buildings (from 1 to 3 passes are performed). The surface is sanded using a power tool (grinder with coarse abrasive). This treatment removes defects left after sawing (or manual processing) - chips and minor cracks. Sanding also opens the pores of the wood, which facilitates deeper penetration of impregnation and paint.
Polishing . It is carried out with a grinder with a fine-grained nozzle or sandpaper (which significantly delays the process). As a result of processing, a fresh, lighter layer of wood appears; the surface becomes even and smooth, absorbs paint better.

Painting the outside of a log house: stages of the process

Protective and decorative painting of a house made of rounded logs on the outside is the key to its long-term preservation without loss of visual appeal. Typically, processing is divided into several stages:

Antiseptic . Impregnation of the facade with water- or oil-based antiseptics and fire retardants disinfects the wood and prevents new insects and microorganisms from appearing (1 to 2 passes are performed). It is convenient to apply the antiseptic through a spray bottle, so a respirator and safety glasses at this stage are not superfluous. Further procedures begin after the composition has completely dried.
Primer . The purpose of the treatment is that the composition prepares the surface for final painting. The primer prevents tree resin from escaping (in knots) and staining the paint.

The paint color is chosen taking into account the style features Source gomabygg.com

Adhesive primer (acrylic or oil, optional). The impregnating composition improves the adhesion of the base paint to the wooden wall and reduces paint consumption. Avoid getting dirt and dust on the drying primer.
Cover paint . The main paint for a log house, the final layer that decorates and protects the walls. The ideal option is acrylic paint, applied in a thin layer sequentially in three steps, using a brush or roller.

Important nuances

We recommend you pay attention to some tips:

When choosing paint for a log home, it is important to choose breathable materials. Otherwise, the wood fiber will not be able to breathe, which will lead to its unusability in a short time. Paints with synthetic compositions should be avoided, as they form a film on the surface that prevents the access of air.
When planning painting, you should not save money, since the appearance of the house depends on it.
Transparent paint looks very nice. If the texture of the house allows, you can use it.
Having purchased paint, you should not delay the work, as it may thicken during long-term storage.
Materials for finishing logs indoors should be looked for with the appropriate marking.

Painting the outside of a log house: factors affecting quality

The quality of painting a wooden country house depends mainly on two factors:

Weather . Ideal weather is dry and windless. Do not paint in the sun (the paint will dry too quickly and unevenly), during or after rain. The permissible temperature is determined by the type of paint (indicated on the label).
Wood moisture content . It should not exceed 20% during painting, so façade walls made of wood with natural humidity are painted after the frame has shrunk.

A necessary condition for a quality result is ease of use Source projecty-domov.ru

Mistakes when painting a log house unqualified

If the desire to save on professional services for some reason outweighs the guarantee of the quality of the work performed, then after a while unsightly results such as stripes, stains and simply peeling areas on a recently painted surface are very likely. In such cases, the quality of the paint product is not always to blame. Unprofessional builders, due to inexperience, make basic mistakes that affect the final result:

The facade is not properly prepared for painting: poor-quality sanding (or lack thereof) leaves the surface rough.
painting technology (sequence) is violated
Work is carried out in unsuitable conditions (high humidity or under the scorching sun).
Newly erected ( naturally damp ) walls are painted.
Incompatible materials were selected for painting .

Peeling of paint is caused by a violation of technology Source otdelka-expert.ru

Types of antiseptic impregnations

We should start the review with washable wood preservatives. They are made on an alkyd-alcohol base, which also includes metal salts. But, as the name suggests, such products are washed away. That is, it is useless to use such an antiseptic when treating the outer sides of walls - after a short time the composition will be removed from the structure. But internal processing can be done using this impregnation, since it is harmless to human health.

The opposite of the remedy described above is a hard-to-wash antiseptic. This is a product based on a combination of synthetic and vegetable oil. This type of painting of a log house can be applied to both external and internal walls. Hard-to-wash-out impregnations remain resistant to precipitation and fully meet environmental safety requirements.

Painting an old wooden house

Over time, the painted facade begins to lose its attractive appearance - the paint peels off, mold appears, and the south side fades more rapidly. Sooner or later, the external walls of an old country house will require updating. Before repainting, the old coating is cleaned (for example, with a wire brush), and the surface is inspected to identify possible defects.

To ensure that the new layer goes on smoothly and lasts as long as it should, choose the same type of paint that was used originally. A study of the texture of the old coating will help determine what the façade was painted with:

Acrylate paint . Thin, elastic structure reminiscent of leather; You can roll a piece of peeling paint into a roll.
Oil paint . It has a matte color and may leave marks on your fingers after touching. You won’t be able to roll the roll—the fragment will crumble.

Old walls need careful preparation Source color-kostroma.ru
An old wooden house is painted in the same way as a new one. The difference is that it is not recommended to paint the old facade with a roller; it does not fill the unevenness that appears after periodic swelling and shrinkage of the fibers with paint. To give the old façade a neat look, painting the log house can be done in three or more layers.

Design styles

Classic involves the use of white, cream, beige and light shades.
It is characterized by symmetry, precise forms, correct geometry and architecture. The interior is furnished with solid furniture and massive decorative elements. You will see paintings on the walls and voluminous vases on the floor, heavy curtains, lambrequins and draperies on the windows. The bedroom and living room are decorated in this style. It is desirable that the rooms have high ceilings, otherwise heavy curtains with draperies or lambrequins will make the space heavier and smaller. Classic style will make the room festive, romantic and luxurious.

Empire style is distinguished by red and bright, white and cream colors. Here you will see a lot of gilding and various decorations. To decorate this style, tablecloths, furniture covers and velvet curtains with embroidery, curls or drapery are used. To equip this design of a log house, heavy double doors and large furniture are installed. It is suitable for furnishing spacious rooms, such as a living room or dining room.

Art Deco emphasizes strict geometry and patterns. When decorating, geometric patterns and ornaments, stepped shapes and discreet stucco molding, wide lines and streamlined curves are used. Here you will not find bright colors and elements of romanticism. This style is characterized by halftones and predominantly dark colors, among which brown and beige, black and purple, and green are often used.

You can play on the contrast of black and white, black and purple, black and green. This style is distinguished by luxury and chic. Expensive materials are often used, including rare woods, silver, ivory, crocodile skin, etc. Art Deco is suitable for rooms with high ceilings.

Modern is a light, soft and sophisticated style that is suitable for a comfortable stay. Here they use light tones and muted colors, natural colors, smooth and flowing lines. You can see arches instead of doors, nature-themed wall paintings, light curtains and round tables.

Due to its closeness to naturalness and the use of natural motifs, modernism is perfect for decorating the interior of a log house. And since it encourages relaxation and creates a comfortable and cozy environment, a bedroom, a guest room, or a living room with a fireplace are decorated in this style.

High-tech is a modern and practical style that allows the use of open communication pipes. This simplifies finishing, but does not provide complete safety in a wooden house, as experts advise covering pipes and electrical wiring. When decorating this style, glass and metal, synthetic materials, sliding doors and transformable furniture are used.

Here you can often find panoramic windows, smooth and even surfaces, an effective combination of space and light. The main colors used are grey, metallic and silver, black and white. Small rooms are decorated in this style, as it allows you to save space and functionally distribute the space in the room. This is an attic, an office or a kitchen.

Exterior painting of a log bathhouse

A bathhouse is a building with specific operating conditions; the interior of the log house is exposed to high humidity and temperature. Therefore, the main condition for the external coating is to maintain the vapor permeability of the walls. Otherwise, moisture will linger in the wood for a long time, creating a favorable environment for the development of mold microorganisms. When thinking about how to paint the exterior of a log bathhouse, do not forget about the nuances of processing the loghouse of a bathhouse:

Logs must be dry and clean .
In order for the protective layer of the new log house to serve as reliable protection, the lumber is treated with stain before collecting the crowns .
Before repainting, the structure must be cool and ventilated .

Impregnations are conveniently applied in the following sequence:

Antiseptic . Products based on natural and synthetic oils are optimal.
Fire retardant.
Dye . The best option is acrylic facade paints, non-toxic, durable and vapor-permeable.

Another way to protect a sauna stove from negative influences

You don’t have to think about how to paint an iron stove in a bathhouse, since not only paint can protect it. The method of metal bluing, which involves creating a chemical reaction, is widely used.

First the surface must be cleaned. To do this, use a 5% sulfuric acid solution, which should be applied with a brush. Then the laundry soap is diluted in water in a ratio of 50 g per 1 liter. This solution must be used to wash off the previously applied sulfuric acid. Next, the oven is heated to 150-180°C and treated with caustic soda diluted in water in a ratio of 50 ml per 1 liter. The composition should be applied only by spraying to avoid splashing.

Conclusion

In order for the stove to serve for a long time, it must be well treated, and for this you should make the right choice of what to paint the stove in the bathhouse with. The solution to this issue should be taken with full responsibility and there is no need to save money, because the stove is the main component of the bathhouse.

Principles of coloring

In order for the decorative coating to last longer, you need to take into account the specifics of the work and know how to prepare the surface.

Preparation

Before you start applying paint to the walls, floor, ceiling in the bathhouse or outside, you need to complete the following preparations:

Caulk the timber walls, cover the cracks with a special wood putty. The walls must consist of several layers - vapor barrier, wooden frame, insulation, foil film, slatted frame, finishing material. Paint is applied on top.
You need to remove uneven surfaces from brick surfaces and knock down old mortar. Depressions and cracks should be covered with plaster.

After leveling the surfaces, you can begin decorative finishing.

Tools

To perform the work you need to prepare:

Tassels. Can be with natural or artificial bristles.
Rollers. There are fur, velor, polyamide, foam rubber.
Sharp knife, scissors.
Dry rags, solvent.
Containers for paint.
Thick polyethylene film.
Plastic stick.
Masking tape.

If you need to paint the outside of the building, it is recommended to use a spray gun. With its help you can quickly paint large surfaces.

Features of the work

You need to start painting the walls, ceiling, floor by cleaning the room and preparing consumables. All items that cannot be painted must be covered with plastic wrap. Skirting boards and trim can be sealed with masking tape. The composition is applied in one layer. If it is not enough, you can apply a second one. Metal surfaces must be pre-primed.

Brief conclusions

I will answer a possible question - is it possible to paint a stove in a bath with oil, alkyd, vinyl, latex, acrylic, dispersion and other paints. I answer - it is possible. Just bake, don’t heat it later...

Tikkurila - heat-resistant paint

There is another option - experiment. For example, a friend decided to use paint for car mufflers, someone is trying something based on liquid glass, and so on. There are many different forums. If you do not want to paint an iron stove, you can do bluing. We associate this word with firearms. A good low budget option. How long will it last? Don't know. But good heat-resistant enamel is promised by manufacturers to last for at least 15 years.

Table of end finishing products

Name	Manufacturer	Properties
Senezh Tor	Russia	Good protection due to the penetration of the material several cm deep into the log house. It has the ability to allow air to pass through, but does not release moisture from the material. This means that the log house will dry as naturally as possible. Environmentally friendly product
Neomid Thor Plus	Russia	Forms a thin film on the surface of the log, which is water-repellent. Protects wood from cracks and putrefactive processes
Biotor	Russia	Thanks to the solution, the log will deform significantly less, since the product protects against dried cracks

Compositions

Many people will immediately answer that there is no need to treat it inside at all, because there is “chemistry” everywhere, and it is always harmful, especially in a bathhouse. If we understand by “chemistry” artificially obtained organic compounds, then yes, many of them will not bring anything good to living organisms if they get inside. But, excuse me, we ourselves also consist of organic compounds, and we eat them too. You just don't have to ask the question like that.

A steam room is a place where elevated temperatures make various substances more volatile. These are the smells of herbs, and resins in wood, and phenols in mineral wool... In general, if you smell the smell, it means something has warmed up and is “phoning.” It’s bad when paint or varnish, or PVC, or mineral wool, or sulfides in stones begin to “sink.” Therefore, they try not to put plastic in the steam room; for insulation they use only those heat insulators that do not release binding substances when heated (if mineral wool, then with a mark on the packaging “for saunas and baths”)...

IMPORTANT! They also refuse to use varnishes and paints based on organic solvents.

But the modern paint and varnish industry has already taken a technological step towards greater humanity and environmental friendliness. Now there are water-based varnishes and paints that practically do not smell when applied, and after drying they form a fairly durable polymer that does not smell of anything at all.

Therefore, the Finns, knowing perfectly well what temperature conditions they have in their steam rooms, make and sell compositions that have been tested and are considered safe. These are water-based acrylic coatings. Or they are impregnations made from completely safe oils - linseed, paraffin...

However, don’t even let the paint harm your health with its smell, it reacts quite poorly to moisture, tends to peel off, hang in rags... Therefore, if you paint the steam room in a bathhouse with anything, then only with special compounds that are suitable for bathrooms (also written on the packaging ). Such coatings are waterproof.

Lucky

After all, natural wood in a steam room is such a built-in standard. Therefore, somehow the thought does not arise about paint that will hide the texture of the wood. And there is no need - now you can tint the varnish with any color - be it green or pink.

Let’s think for a second about why we should even look for varnish for the steam room in the bathhouse. Wood that is heated and moistened undergoes deformation - it gains moisture, swells, then contracts in volume, and often cracks after this. And if it fails to dry properly, fungi and bacteria take advantage of this, converting the cellulose into rot.

So, coatings such as varnish are not so much for beauty, but for protection - from cracks and deformations, from mold.

You can protect the floor by using waterproof yacht varnish. Even though it contains polyurethane or urethane. The thing is that the temperature on the floor in the sauna is low - the Finns are required to have a 5-10 cm gap under the door to the steam room.

In a Russian steam room, if you don’t make special heated floors, it’s also not that high, it’s unlikely to be higher than 30 degrees. Therefore, yacht varnish will not hurt here either.

Waterproof, highly abrasion resistant varnish will make the floor more durable. Just don’t allow a problem like the one in the video below.

The walls can also be varnished, but this time it is safer.

ATTENTION! This can be any acrylic varnish that clearly states that it is intended for sauna walls.

Such varnishes are available from different manufacturers - both Russian and foreign. Teknos, Belinka, Tikkurila, Dulux have them, as well as ours - Neomid, Senezha, Rogneda, etc. If there is a certificate, it means the product is good.

Oils

When they talk about “oil for a steam room in a bath,” they mean impregnation for wood, but not drying oil. Compositions have long been developed that do not smell like drying oil. In particular, there is no smell from paraffin oil.

Treatment of the bathhouse inside the steam room with oils is usually limited to covering the shelves with them. This is done because it is the safest way for humans to protect the tree.

On sale you can find both liquid oil compositions and more solid varieties containing, in addition to oil, also beeswax. The latter are even better, considering that wood has been waxed for a long time, and not only for a beautiful shine, but also to increase its service life and protect it from all kinds of pests.

Color selection, recommendations

To choose the right paint color, you need to take into account the style of the interior - the color of the walls should be combined with the design and style of the room. If you want to decorate the inside of your house in a classic style, then painting should be done with transparent compounds to highlight the beauty and grain of the wood. The Scandinavian style is characterized by pastel and white colors. If you need to visually expand the space, then you should choose light-colored paint, and if you need to narrow it, then dark ones.
