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

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).

The type of paint is chosen based on its protective properties and visual appeal Source derevyannyy.com

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.

The use of certified paints is a guarantee of high-quality painting Source fasad.guru

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.

Types of decorative impregnation with water-based acrylates Source plantu.ru

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.

How to coat a log house after sanding

Question:

Good afternoon, Semenych! Please tell me, in the spring of 2018, a log bathhouse was installed from a winter Siberian forest (diameter 36-48), the lower three crowns are made of larch, the top is pine. The roof and ceiling were done almost immediately after the frame was built. Now we sandblast it.

The question is what to cover after sanding (primer, bioprotection, fire protection), in what order and in how many layers. We want to coat the outside with matte or semi-matte varnish. Which products are better - there are many manufacturers, and prices vary. Please advise.

Best regards, Elvira, Irkutsk.

Answer:

Hello, Elvira from Irkutsk!

In our practice, we most often cover the outer surfaces of log houses with belinka, tecurilla, and penotex.

True, sandblasting is far from the best option. We prefer to grind with conventional angle grinders; they leave less abrasive on the surface of the logs.

However, if after any type of sanding you walk over the logs with brooms, mops or a vacuum cleaner, there will be much less of this abrasive.

Builders do not have a unanimous opinion regarding the order of operations for coating wood with specific compositions.

Some first treat with antiseptics, which include both fire and bio protection, then apply a primer, and only then paint and coat with colorless varnish. Others do not use this order.

There are now a lot of different compounds on the market, I wouldn’t like to advertise them. In each case, you should carefully read the instructions on their labels. In this case, the most important thing is that all subsequent compositions are compatible. Because sometimes this is not the case, and after a year or two, or even a shorter time, the layers begin to separate from each other, crystallization of salts, their peeling, cracking, etc.

As a rule, brands from more well-known manufacturers, preferably imported rather than home-grown ones, have higher quality and longer-lasting characteristics. Although sometimes I had to run into expensive counterfeits of domestic “Kulibin” ones.

As they say, there are no comrades according to taste and color. But choosing colors and shades of dyes is also a difficult decision.

No matter how high-quality the dye is, over time (when after a year or two, when after five, or even ten years) it can still change its color tone. Atmospheric environment - rain, fog, dew, snow, etc. doing their job.

Most often, darker colors (like rosewood) are less susceptible to changes over time compared to lighter colors (pine or Oregon).

But not everyone likes dark colors, too gloomy, lighter ones are much more pleasant.

When you paint it in a light tone, it can darken very quickly and it happens that you can’t look at the logs of such a log without tears.

Just for fun, walk around and look at the wooden houses with different colors. I'm sure you'll notice the differences right away. And only then make a decision.

Varnish finishes are generally the right choice because the varnish fills the pores left after painting and the wood is less affected by the atmosphere.

So read everything I have said and take action. I understand that I’m not giving you definitive recommendations, but what you read shouldn’t make things worse.

In any case - good luck!

The method of applying the compositions is also important. The use of compressor devices for spraying them is productive, but the traditional old method of rubbing in with brushes, although a slower process, is of higher quality.

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.

Sanding prepares the surface for painting Source gdeprosto.ru

Why and from what wood needs to be protected

The outer layer of wood, devoid of bark, is completely defenseless both from the destructive effects of wind and sudden fluctuations in humidity, and from insect pests. The risk increases if the house is located in a rural or wooded area. This is explained as follows:

As a result of complete cleaning of the wood surface from bark, it is easier for wood-boring beetles to access it.
Under the influence of constantly changing relative humidity levels throughout the year, mold appears on wooden houses over time (usually in inconspicuous places, where it is most difficult to remove).
Moisture stains remaining on an unprotected surface provoke the development of fungal diseases on the wood.
With constant weathering, the surface of the building changes its natural color, becoming dull brown, which is why a wooden house loses its aesthetic appearance.

Based on this, when a wooden house is ready, it should be subjected to surface sanding, antiseptic treatment, and then painting.

Painting logs on the outside has a number of advantages:

paint and varnish materials prevent destruction, dampness and rotting;
antiseptic treatment protects the log house from pests, fungal mold and corrosion;
Exterior painting provides an opportunity to create a façade that fits perfectly into the architecture of the house and landscape solutions.

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.

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.

Preparatory stages

Before applying painting materials to the frame, it should be thoroughly processed. First you need to remove all contaminants from the surface. A brush with soft bristles, a washing vacuum cleaner or an ordinary garden hose are suitable for this. Just be careful not to water the logs abundantly; the tree may become saturated with moisture and will take several weeks to dry.

Grinding

Sanding of the log house cannot be performed immediately after completion of construction work. Wood with high humidity is poorly processed, and any further coating will look unsightly on a poorly polished surface. Therefore, the house must stand for at least a month. It is also recommended to carry out such work at an ambient temperature of no lower than 10–15 °C and no higher than 30 °C. For internal surfaces this circumstance is less critical than for external ones.

Before starting grinding, the log house should be checked for leaks. The result is to caulk possible cracks and gaps left after construction. If this stage is not necessary for houses made of laminated veneer lumber, then log buildings (especially in the crown joints) may have some leaks that must be carefully sealed using acrylic or silicone-based sealants.

Since wood of normal humidity is sanded quite easily, you should not use a massive tool. The optimal power of an angle grinder is 800–1000 W. In this case, the size of the grinding disc must be consistent with the diameter of the rounded log. Preference is given to machines that allow you to adjust the speed of the grinding disc.

When sanding with your own hands, work begins with the back walls and the most even areas: this makes it easier to get used to the tool. When calculating the required time, it is worth remembering that it takes about 5–8 minutes to process one linear meter.

Then you should sand the surfaces of the ends inside and outside the house with sandpaper. This processing stage is quite labor-intensive. The smoother the surface, the easier and faster the protective impregnation of the wood will apply. A grinder with an emery wheel will help speed up the grinding process. To sand wood, you should use two types of sandpaper: coarse and fine grit.

Grinding is performed using circular movements of the disc over all elements of the frame, starting from the top rows. It is not recommended to treat all walls and areas at once - the sanded surface quickly becomes weathered, and therefore requires immediate impregnation with an antiseptic. Therefore, the processing process should be divided into a number of successive stages.

In hard-to-reach places, grinding is done manually - using a chisel.

Antiseptic impregnation

Logs require immediate surface coating with anti-rot compounds, which should be done immediately after sanding. For this purpose the following can be used:

Bioprotective compounds that protect wood from the harmful effects of ultraviolet radiation and also increase the moisture resistance of wood.
Fire retardants that provide adequate fire protection for your home. They are carcinogenic substances, so special precautions are required when handling them!
Combined preparations that combine both fire-resistant and moisture-preserving impregnations. For example, acrylates are substances that, when painting a surface, simultaneously increase its resistance to adverse external factors.
Antiseptic compounds. Antiseptics for internal and external use are produced separately.
Compositions that destroy tree pests. For this purpose, fumigation (fumigation with special generators) is used after grinding. To do this, it is better to invite specialists. Also, to combat wood borers, they are treated with ultrasonic fields. In the interior of log houses, you can use a regular microwave oven with the door open, but you should be careful - it is dangerous.

Fire-, bio- and moisture-resistant impregnations are applied in 2 layers and left for 10–14 days for complete absorption and distribution throughout the wood.

In order to save money, you can use the “old-fashioned” secrets of processing a house made of logs. Wax and turpentine have long been used in equal proportions to protect against rodents. The inside of the log house can be treated with starch or laundry soap.

Machine oil can be used as a water-repellent layer on the outside.

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.

Sanding a log frame made of cylindrical logs

After initial processing, logs always have defects and irregularities that must be eliminated before painting or coating with compounds that prevent rotting and destruction of the wood. For this, a grinding process is used. It is carried out immediately, as soon as the log house dries in natural conditions and sag slightly. You cannot delay this operation, otherwise the logs will darken, harden and become less amenable to processing.

What does sanding a log frame provide?

No matter how durable a wooden house is built, it will be exposed to natural factors all year round. Therefore, it must be reliably prepared to withstand winds, frosts, scorching sun and precipitation. For this purpose, the log building is polished. This operation helps solve a number of important problems, namely:

stop wood aging;
prepare log walls for subsequent processing;
eliminate defects and give the wood a natural structure;
improve the adhesion of oils, paints and other protective and decorative compounds;
make a log building aesthetically attractive and noble.

Sanding a log frame made of rounded logs, the cost of which is quite reasonable, allows not only to extend the service life of a wooden structure, but also to give it a beautiful and more luxurious structure. Therefore, it is important that the grinding of a rounded log house is carried out with high quality and in compliance with technology, then it will fully perform both protective and decorative functions.

Leave the sanding of the log to the professionals!

The cost of sanding rounded logs depends on the area of the surface being processed and the quality of the initial processing. It is carried out in the presence of protective equipment, consumables and special tools - an angle grinder, a grinder with discs of different grain sizes. This process itself is time-consuming and labor-intensive, and therefore requires practical training.

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 .

Sanding a log frame

Sanding a house made of rounded logs, even using a special tool, requires a lot of labor and time. In addition, the technological process is accompanied by a lot of dust, and, consequently, the need to use respiratory and eye protection.

Experts will solve the problem. They will complete the order in accordance with the client’s requirements, and he will save his health and time.

The technological process proceeds in stages:

Chernova. Performed with grinders, flap grinding wheels, and 60-80 abrasive.
Basic. Eccentric machines are used with an abrasive of 100-150. They completely eliminate the smallest irregularities on the surface of the walls.
Polishing. It is carried out to obtain a perfectly smooth, shiny surface. It is performed using vibrating machines, 150 grit.

Depending on the initial condition of the wall surface, the process may consist of 2-3 passes. If this service is ordered as a preparation before covering walls with paints and protective agents, then tools with an abrasive size of no more than 120-150 are used. As a result, the service life of the finished coating is greatly increased

After the facade, the ends, corner joints, and grooves are processed. An angle grinder or grinder with a thin attachment in the form of a special brush is used. The cost of polishing the end of a log frame made of rounded logs starts from 220 rubles per lin. meter.

Service price

Processing and cleaning a wooden surface is a labor-intensive process that requires accumulated experience and time. The cost of quality work cannot be low, but the costs will be justified by the long-term operation of the house in excellent condition.

The price of sanding a rounded log per square meter depends on the amount of work and the characteristics of the material. On average in Moscow, prices start from 300 rubles per sq. m. meter.

The final cost is influenced by factors such as:

Working volumes. They are performed on the entire object, or on a separate part of it.
Is the pediment sanded?

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.

How to sand and paint a log house.

Upon completion of the construction of a wooden house, multiple finishing works are performed, including sanding and painting the frame.
Many people consider the need for resurfacing to be an optional procedure. Experts recommend not to ignore this stage of work. Sanding a log frame is a rather labor-intensive job that requires some knowledge and skills, the availability of special tools and a sufficient amount of time to complete it.

Main goals of grinding:

Restoration of appearance. Under the influence of external atmospheric phenomena, the surface of the logs begins to darken over time. Sanding returns the original appearance, the wood becomes light (as if it had just been cut down).
To protect against fungal infections and mold. If the conditions of transportation or storage of wood are violated, fungal or mold damage may occur, and dark spots may appear. They can be removed by sanding.
When sanding, the grain and texture of the wood becomes more apparent.
Increased adhesion to paints and varnishes.
Protection against premature aging of wood.

You can start cleaning the log house only after it has dried thoroughly. The roof must be installed. If you try to sand immediately after assembly, the wet wood will scuff and you won’t be able to get a beautiful smooth surface. Sometimes the logs of a log house may turn blue or darken; in this case, the first priority is treatment with a bleaching antiseptic. After the surface has dried, start sanding. If the sanded surface is not coated with a protective compound, it will darken within a week. When sanding a log house yourself, furrows and holes may appear on the log house - traces of too much pressure; we have a specialized team on staff that professionally performs this work. Particular attention should also be paid to the ends of the frame; it is impossible to make them perfectly smooth, but they need to be sanded - they absorb better, so you have to lubricate more generously.

To grind logs and beams, you can use two types of tools: grinders or grinders with appropriate attachments. For grinding, you need a supply of attachments with different grain sizes. For the initial processing of logs with bark residues and various types of unevenness, you will need sandpaper with a coarser grain, and for the finishing pass - fine-grain sandpaper.

There is another method of polishing a log house - sandblasting facades. This type of treatment eliminates the appearance of pits and furrows, helps to open the pores of the wood, this allows the protective composition to penetrate deeper and create a protective layer. There are various cracks and hidden surfaces on the surface of the logs; first of all, they contain various fungi that cannot be cleaned out with hand tools. Abrasive blasting cleans such areas uniformly, after which they must be protected with an antiseptic. The meaning of this technique is to clean the surface with sand particles under pressure, along with an air flow. Please note that regular sandblasting is not suitable for cleaning a log house. It will damage the surface. The advantages of this cleaning method: high speed of work, the texture is revealed most advantageously, corners and hard-to-reach places are well processed, opening the pores of the wood, no damage to the wood from sanders or grinders. Disadvantages: high cost, need to use equipment.

Our experts advise painting the log house within a maximum of 36-48 hours, after sanding at above-zero air temperatures. External processing of a log house consists of grinding and painting with various compounds; these measures can extend its service life several times.

There are a large number of paint and varnish products that are used to treat a log house after sanding. Please note that not all products are suitable for use in residential premises.

The main function of processing a log frame is protective; the natural texture of the wood is also emphasized and it is tinted.

Means for coating the log house after sanding:

First layer: antiseptics that prevent the appearance of mold and mildew;

Second layer: Painting. Compositions with glazing properties that make the appearance of walls more attractive or covering compositions that paint over the wood texture;

Finishing layer: fire retardants - solutions that increase resistance before fire.

It is better to paint a log house with a brush. This option, when painting, is the most preferable, in our opinion, since the composition is rubbed and penetrates deeper into the wood, and accordingly the protective properties increase.

The compositions are also applied using a spray gun (spray gun).

Coating application is ensured by pneumatic spraying through finely dispersed crushing of the paint composition. This technology applies only to a small area of painting to avoid sagging and overlaps. Sagging and overlaps must be smeared immediately. It is important to maintain the same distance between the wall surface and the spray gun; the speed of movement of the spray gun should also be the same. The use of a spray gun is unacceptable for the use of translucent compositions, but for covering paints, a spray gun can be used, since when the paint is applied opaquely, the overlaps become invisible.

If you paint the walls of a house with a spray gun, to improve adhesion, a person with a brush should follow you, this way it is possible to avoid smudges and the composition will be absorbed deeper.

The main rule for durable wall treatment is the use of high-quality compounds. Saving on materials leads to the fact that the log house will suffer first, since wood is a rather vulnerable material that requires careful care.

We employ qualified craftsmen with many years of experience in sanding and painting log frames. Also, our own department of paint and varnish coatings and tinting equipment provides a wide selection of impregnations for wooden surfaces to suit every taste and budget.

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 .

Stages of processing and painting a bath Source do.59.ru
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.

When to do it?

Building a high-quality wooden house is never quick. First, the material is delivered to the site, then it is installed and roofing work is performed. All this happens over the course of one season. The drying process of wood lasts 1-2 years, depending on the cutting season, storage conditions of the material and its characteristic features.

During the entire period of drying and shrinking of the wood, sanding is prohibited. According to experts, at this stage there is also no need to use antiseptics, since the structure of the wood will not change significantly throughout the year. During grinding, you will be able to remove darkening, since the procedure involves removing at least 1-2 mm of the top layer of material. Installation of doors and windows is carried out after sanding.
