At first glance, such a simple and unpretentious process as painting a tree does not require any special knowledge and skills. However, this is not quite true. The abundance and variety of modern paint and varnish materials (LKM) requires compliance with the rules and conditions of work.
All paint manufacturers accompany their products with detailed instructions. But in some cases they are not enough to obtain a high quality painted surface.
Therefore, beginners in this business try to focus on the advice and recommendations of specialists, whose experience has been gained through many years of trial and error.
Painting a wooden house
A properly processed facade increases the service life of the house several times.
Before choosing a paint, you need to pay attention to the quality of wooden surfaces. If the walls are built of logs or beams, there is no need for their preliminary mechanical preparation for painting. In this case, it is enough to choose the right painting tool and paintwork.
Sanding such walls will be difficult, especially if the lumber is old.
Modern wood cladding elements go through a grinding stage during the production process. But if necessary, additional machining of the boards is performed. This will allow for better painting of the facade. Then proceed to the choice of paint.
If you take this matter without proper attention, soon after its application, you can get such negative effects as loss of color saturation, peeling and cracking of the protective layer. It doesn't take much effort to prevent these troubles. It is enough to familiarize yourself with the instructions for choosing paint and the technique of its application.
The paint fits perfectly on the prepared surface
First of all, you need to learn one rule: any wooden surface requires preparation for painting. You can't just buy paint and apply it.
It is necessary to give the surface certain properties. This can be done using special compounds, the purpose of which is to ensure the protection of wood and increase the degree of its moisture resistance. This is especially important for those elements that are outside.
Choosing the right primer is easy. You just need to carefully read the manufacturer's instructions, which, as a rule, are on the label or directly on the surface of the container with the solution.
There are several types of primers.
Types of primers
All of them perform several tasks: they disinfect and degrease the wooden surface, give it resistance to moisture and protect against insect pests. An ignorant beginner in painting may have a question: why do you need such a variety of primers? The specialist will answer: in order to take into account all the features of different types of wood and the purpose of the painted surfaces.
HUSKY Interior. Exterior Primer - 100% acrylic primer for interiors and facades
Acrylic compounds are versatile.
They can be used to protect any wood, chipboard, fiberboard. Alkyd primers are needed in cases where the most thorough preparation of the surface is required for painting or gluing decorative elements. For example, these compositions are popular with those masters who are passionate about decoupage. Alkyd primers are able to fill the smallest pores of wood, which makes the surface smoother and smoother.
Primer for wood for painting
If it is necessary to process a structure located on the street, preference is given to compositions based on silicone and acrylic.
They are able to provide the maximum possible waterproofing effect on wood. Primers based on shellac and epoxy resins are a full-fledged paint and varnish coating that, in addition to bioprotective surface treatment, paints it in the color indicated on the container with the composition.

There is another gradation of primers: according to their functional features. Here, a distinction is made between deep penetration and varnishing effect compositions. Choose the one that best suits the particular case.
In the production of finishing facade works, the most demanded are deep penetration primers with bio- and moisture protection properties.
All paints for wood are divided into two large groups: for internal and external work. The former are used for finishing wooden surfaces indoors, while the latter are used to cover those located outdoors. For painting facades, a composition for external work is required. This is the first step in choosing a paint.
HUSKY [Husky] Super Paint Exterior - 100% acrylic super-resistant facade paint
The second is to choose its type. There are several:
The former are not recommended for use for facade work. These paints (oil paints) have several drawbacks that will significantly complicate the production of external work. First of all, it is a long drying period.
On average, at least 48 hours should elapse between applications of the first and second coats in favorable weather conditions, and at least 72 hours in unfavorable weather conditions.This is a rather significant break from work.
Another disadvantage of oil paints is that they fade quickly when exposed to the sun. It is also prone to cracking. But they also have a special advantage: low consumption, provided by a high degree of viscosity of the composition.
Oil paint MA-15 "Economy"
Alkyd paints - a popular and fully justified choice in the production of facade work. These compounds qualitatively protect and color wood of any species. Surface conditions can be the most challenging. But the wall or element of the fence must be primed. In this case, all roughness and small differences in height will be smoothed out.
Therefore, the paint will lay down easily and evenly, which will ensure the quality of the coating.
Among the advantages of alkyd enamels are UV resistance, frost resistance, moisture resistance, crack resistance. But still the best choice for facade work is silicone-based paintwork. One layer of these enamels is sufficient for high-quality wood protection. Thanks to the silicone included in their composition, the covering ability is significantly increased.
The coating is durable and maximally resistant to environmental influences. Silicone enamels meet all the requirements for external work. Therefore, these paints are the most expensive.
latex paints have no less high-quality covering ability. They have another property of no small importance for facades: a high degree of resistance to moisture.
But acrylic paints are much more popular. The main role in the choice of these enamels is played by their low price.
It is important to know: experts do not recommend using enamels for painting facades, which are diluted with white spirit. These are alkyd and oil paints.
If the question arose about which manufacturer to give preference to, domestic or foreign, it is advisable to opt for the first option.
The fact is that the compositions of European manufacturers are designed for operation in a milder climate than the Russian one. The products of Spanish, Italian, German, French enterprises are suitable for facades in the southern regions of the Russian Federation. For the northern ones, it is recommended to use the products of domestic enterprises, which take into account the peculiarities of the Russian climate.
Wooden facade paint
Structural facade paint
Optimal choice for areas with cold winters - water-borne paints and glaze antiseptics . Here you can use the formulations of Finnish and Swedish manufacturers.
In these countries, the climate is more severe, therefore the enamels produced there have frost resistance and moisture resistance necessary for facade work. An excellent choice is the products of the Tikurilla and Sadolin companies.
Valtti Color Satin
A new generation tool - "Valti Color". It is a glazing antiseptic that can be applied to wood of any complexity. The experience of use by Russian homeowners suggests that within 5-6 years the coating formed by this composition does not lose its operational and aesthetic characteristics.
Enamel similar in quality - "Pinotex".

If there is a need to completely cover the texture of the wood and get an even smooth surface, it is recommended to use water-soluble enamel. For example, "Aquatex". These compositions are more durable than oil and alkyd.
Glossy acrylic water-based enamel
The technology of painting wooden surfaces provides for the implementation of several simple rules.
First of all, you need to know that houses that have not passed the shrinkage stage cannot be painted. This will be a waste of time and money, as the applied layer will inevitably crack and partially crumble.
Log shrinkage - wait, you cannot work
It is not recommended to paint a bar and a log that has not given up moisture, that is, freshly processed. For the period of shrinkage at home, they are covered with a special preservative based on volatile solvents, which has the ability to penetrate deeply into the pores of the tree and accelerate the process of moisture release. Only then can you start painting the facade.
If it is not known whether the wood is dry enough, it is recommended to stop using film-forming materials such as glazing antiseptics and alkyd paints. If the walls have an optimal moisture level (10%), the best choice for painting them is a topcoat or a translucent glaze antiseptic. You can choose a composition of a covering or semi-covering type. Both types of these enamels will provide high-quality and aesthetically pleasing wall protection.
If there is a desire to get the texture of siding under a tree on the facade, use Vinha paint.
After drying, it completely hides the natural texture of the wood and forms a surface that mimics the relief of vinyl siding.
All structural paints have a similar effect.Otherwise, these enamels are called "textured". They are capable of forming a relief up to 3 mm deep. They can be applied to any type of surface: concrete, brick, plaster.
Average consumption 700 = 1500 g / m2.
Textured material for decorative embossing
Painting the facade is carried out at an air temperature not lower than + 5 ° С and not higher than + 25 ° С. Another important point to be aware of: work begins not in the early morning, but at 10-11 o'clock. By this time, the walls of the house will dry out from the night moisture and morning dew.
For normal paint application, you can use:
To apply textured paint, you will need other tools and materials.
Mixer for paints
Transparent plastic trowel
The best time to paint your home is late spring or early autumn
Step 1. Preparation of wall surfaces for painting.
Remove the old topcoat.
The façade must be dry and clean. Remove dust and dirt with a damp cloth. Then they give time to dry the walls.
If old, peeling paint remains on the house, you need to remove it from the surface
Before you start painting, you need to inspect the house and check for any damage, if necessary, repair.
It is recommended to apply an adhesive primer "TM" or "VGT". For application, use a roller with a short handle or a wide paint brush. Then the work is interrupted for 24 hours. During this time, the walls are completely dry.

Step 5. Without letting the paint dry, rub it with a plastic trowel, periodically pressing on one of its ribs (this will form a relief).
Step 6. Work is continued for 15 minutes, after which the paint will begin to harden and lose elasticity.
Take a break from work for 24 hours.
Step 8. Apply the toning compound using a foam sponge or a paint brush.
