When painting external wooden walls, you need to consider the type of finishing material. Lining, imitation timber, wooden siding are one and the same material. These finishing boards differ only in thickness and profile.
The same paints will work for all these types of cladding and any suitable technique can be used.

If the wall is erected from a bar or rounded log, a different approach to the choice of paint and the method of its application is required. You need to know about this before deciding how and how to paint the walls of a wooden house.
Do not be afraid that in 2-3 years the facade will need to be refurbished or repainted. If you know all the rules and secrets of the staining process, the facing layer will not lose its properties even after 10 years.
Many manufacturers of paints and varnishes (LKM) give a guarantee for a longer period.

Most homeowners who are unfamiliar with the nuances of choosing and applying paint complain that the facade loses its attractiveness the next year after painting. The finishing layer begins to peel off and crack. All these troubles can be prevented.
But even among specialists, few know that in order to obtain an excellent result, you need to change the very approach to painting wood.
This job requires as much attention as painting a car. To obtain a durable veneer, several steps need to be taken:
Careful observance of all the nuances has a positive effect on the result of dyeing the lining
Let's consider each of these processes in as much detail as possible.
Thorough preparation of wood includes several stages. The first of them is high-quality drying of the finishing material.
If the lining is damp, the paint will not last more than 1-2 years. Already next season, its peeling and fading will become noticeable. The owner may decide that the quality of the paint or the inept hands of the workers are to blame, but in fact the reason is the improper preparation of the wood or ignoring this important stage.
Chamber drying of the lining
The board must be dry before painting. The admissible degree of humidity is 15-20%.
But it is not always possible to achieve such indicators, especially for those facades that are already tiled. Craftsmen recommend using this method: build a canopy over the walls to protect them from rain, and dismantle it after 3-4 weeks. During this time, the tree will lose a sufficient amount of moisture and it will be possible to start finishing work.
There is an opinion that the process of drying wood accelerates the application of a high-quality antiseptic of deep penetration. These include Neomid 46 Bio.

Penetrating into the pores, the composition replaces moisture and the process of its evaporation is accelerated. For these purposes, you can use any preservative with which the tree is protected during the construction period of the house. On average, these compounds act for 6-7 months, after which they spontaneously decompose into biologically safe substances.
If the surface of the polyethylene is wet to the touch, it means that the lining is not dry. Such wood must not be painted.
Wood moisture meter
An important point in preparation for painting is grinding boards.
All materials of average quality (grade B and below) need this procedure. Often on such wood you can see "fleecy" areas, irregularities in the profile, height differences in the area of knots. All of the above are problem areas, without eliminating which, it is impossible to obtain a high-quality painted surface.
It is easiest to process the cladding material before it is laid on the walls. In this case, you can use various tools: a milling cutter with a milling cutter of the corresponding profile, angle grinder with an abrasive disc, thickness gauge.
However, the use of mechanical processing does not eliminate the need for manual labor. All grooves and protrusions of the profile will have to be sanded with sandpaper.

Sanding with sandpaper
If the lining is already attached to the facade, use a nylon abrasive brush and sander to process the wood. The sanding process is not fast, but it will allow you not to think about finishing the facade for 8-10 years.
After the lining has a flat and smooth surface, the wood must be primed.
This process should not be postponed for long. Therefore, it is recommended to decide in advance on the type of primer and purchase the required amount.There is an important point in this matter: it is not recommended to choose the most inexpensive composition. It will not be able to provide high-quality adhesion and will not adequately protect the wood from moisture.
A good primer is often more expensive than paint.
This situation is observed in different lines of products of the Tikurilla company. A competent manufacturer knows that the most important part of painting is priming. It is its quality that determines the durability of the paintwork.

The following types of primers are suitable for external work:
Regardless of the chemical composition of the primer, you need to choose those products, the packaging of which indicates that they are intended for facade work.
Another important property that you need to pay attention to is the degree of penetration of the solution deep into the wood. On the primer it should be indicated: "deep penetration".

It is not recommended to use alkyd compounds for facade works. They form a thin film on the surface of materials. It simultaneously protects the lining from pests and the formation of mold, and prevents moisture from escaping from the deep layers of wood.
Therefore, the best choice is water-soluble primers, which include acrylic and / or silicone.
Often on sale you can find acrylic penetrating soils with antiseptic additives
When priming and painting the facade, special attention is paid to the south side of the house. She is more exposed to the negative effects of ultraviolet radiation. Therefore, on the north side of the house, the paint fades less and cracks less often.
Impregnation for wood
Many homeowners make one mistake: they don't read carefully, or don't read at all, what is written on the paint can.
This information contains instructions and recommendations of the manufacturer, following which, you can achieve the desired result. But before it comes to them, you need to decide on the type of paint. After that, you can begin to familiarize yourself with the nuances of its application.
It has been noticed that oil paints lose their color saturation most quickly. They also crack faster than others.
The reason is in the composition of these paintwork materials and their viscosity. The latter property provides a high covering ability, but does not guarantee the quality of the coating. Therefore, oil compositions are rarely used for facade decoration.

The optimal choice for outdoor work is fast-drying water-soluble acrylate paints. You can pay attention to the products of the Tikurilla company.
This manufacturer has a wide range of paintwork materials for facade work. Excellent reviews about Ultra and Pica Techo paints.

For regions with unstable climatic conditions, characterized by temperature extremes and cold winters, silicone-based facade paints are suitable. These compositions successfully withstand low and high temperatures, have a high degree of moisture resistance, and at the same time remain vapor permeable. Silicone facade paint combines the best properties of acrylate and silicate compounds to form a durable, uniform coating.

|Silicone||+ 5 ° C - + 20 ° C||24 -48 hours||150-180 g / m2|
The lining can be painted with wood stain, tinting impregnations and oils. Wax or varnish is used as a topcoat.

Before choosing a method of painting, you need to learn about the rules for performing work, without which you will not be able to achieve a high quality surface finish. The main point is the timing of the work. The lining is painted no earlier than 3 days after the last rain.
During this time, the wood will be able to dry completely.
The air temperature must be positive. The boundaries recommended by manufacturers of paintwork materials - + 5 ° С - + 20 ° С. It is also important to consider the time of day. It is best to start painting at 10-11 am.
By this time, the lining will be completely dry from the morning dew.
The easiest way is to paint the lining before installing it on the facade. In this case, you can get an even layer, without smudges. The paint is applied with a brush, roller or spray gun. Since the boards are long enough, the work is done in a spacious room or outdoors.
In any case, a little preparation is required.
If you decide to work indoors, you need to provide for the possibility of high-quality ventilation. The floor, furniture and household items are covered with plastic wrap. This is especially important if you plan to use a spray gun. Do not forget about your protection.
First of all, you need cotton gloves. If the paint will be sprayed on, wear protective goggles.
The process of applying paint is most simple if you use a high-quality paint brush. The best choice is semi-rigid bristles, with a fairly soft and even edge. The choice of tool also depends on the amount of work.
Synthetic bristle brushes are more durable.
The staining technique consists of several simple steps.
Step 1. Open the container with the paint and mix the composition thoroughly using any convenient device. A wooden batten of sufficient length can be used.
Step 2. Dip the brush into the paint 1/3 of the bristle length.
Step 4. Squeeze the bristles lightly against the edge of the can.
Lightly paint the wood with light strokes.

Step 6. Repeat the process until all the boards are painted ...
Do not put a lot of paint on the brush, otherwise there will be stains
Painting the lining with your own hands
Processing the lining with paint
Choose a narrow roller fitted with a medium-pile fur coat. You will need a paint tray, which is also called a "paint bath" or "building ditch".
Paint tray, roller
Step 1 . Open the container and mix the paint.
Pour paint into a special tray.
Step 3. Immerse the roller in the ink 1/2 of the roller height.
Step 4. Roll the roller over the corrugated beveled part of the cuvette.
Thus, the paint is evenly distributed over the coat and the excess is squeezed out. One set of paint should be enough to paint 1-1.5 m 2 lining.
Apply paint on the roller
step 5. Apply paint by pressing the roller against the wood with even force .

Step 6. Spread the paint so that the surface is high-quality painted over, and there were no smudges on it.
Repeat the process.
Application of paint with a roller
The lining has a rather complex profile, so the edges of the boards will have to be painted with a brush.

For paint can be applied using an airless sprayer. This is the most successful way to carry out finishing work with an already installed facade. The spray method allows you to paint all hard-to-reach areas.
But the areas near window and door openings need to be finalized with a paint brush.
Appliances such as low pressure spray guns can also be used to paint. When working with these tools, it must be taken into account that some of the drops will settle on objects located near the workplace.This is because the paint exit from the nozzle of the apparatus is fan-shaped. Therefore, not all particles reach the façade surface.
Painting with a spray gun
Working with a spray gun is more convenient than with a brush and roller. In addition, the dyeing process will be much faster.
