How to choose a paint for wood, for example, for the facade of a building? A number of commodity items are eliminated at once, they are suitable only for interior work. Here you need to understand that the properties of a paint that will be used in rather unfavorable conditions must be specific: we expect increased stability and durability from such a paint.
The modern chemical industry offers a lot of options, including acrylate paints from various manufacturers (Finnish, Canadian, Russian). And in many cases, the use of such paint is preferred.
Acrylate paint for wood for outdoor use
An exterior paint must have a formula that is unique in many ways.
Such building material must demonstrate resistance:
Composition of acrylate materials for painting
When painting wooden surfaces, keep in mind that wood is a special material. It is a natural, organic material, which is characterized by such disadvantages as the possibility of rotting, mold, and other harmful microorganisms.
In addition, the material has a specific structure (depending on the type of wood), which we would like to preserve without having a destructive effect on it.
Painting is a means of protecting your wooden house, increasing its durability and improving its appearance for decades.
In this regard, we can add new items to the list of requirements for paints for outdoor woodwork.
Such building material must:

What suggestions do we have from manufacturers? The choice among excellent building materials is quite rich.
Many modern specialty exterior paints meet most of the above requirements. In addition, they are distinguished by a beautiful shade that does not disappear over the course of several years.
Each type of paint has its own merits, and in order to make the right choice, you need to understand what characteristics are important in your case.
For example, traditional oil paint has not only good performance, but also a heavy odor, and when using them there are difficulties with a long drying time. Another problem: they quickly lose the brightness of the hue.
Moreover, their price is acceptable for many.
Oil paint for exterior and interior use
Acrylate paints belong to the family of more modern materials. They are environmentally friendly, allow the wood to breathe, provide air penetration through the entire surface (important for all types of wood), which makes the house more durable. In addition, they have almost no smell, they do not have a harmful effect on construction workers. Such paints dry out in a short time.
A wide range of tools can be used for painting with acrylate paints. In any case, the result of construction work will be excellent: a brush, a spray gun, and a roller of any size will do. The consistency of the paint allows you to change tools without compromising the quality of the final work. The facade will look great! And one more serious argument in favor of acrylate paints: they mix well with each other (which cannot be said about oil paints). This property allows you to create new custom shades.
When using acrylate paints, the color layer is highly elastic. This gives the effect of a smooth, even coating on which even small cracks do not appear, despite the building's shrinkage processes.
Features of the production of acrylate paints
The advantages of such paints include:
But the disadvantages include only:
The use of acrylate paints
Let's figure it out with such a nuance, what is the difference between acrylic and acrylate paints. On the shelves of building materials stores, you will see both names. Maybe we are talking about the same product, which different manufacturers simply call it differently? No, the difference still exists and consists in the addition of specialized chemical impurities: concentrated compounds are the binder in acrylic paint. No additives or impurities are used.
For the production of acrylate, special substances are used: acrylate-copolymer dispersions, which provide a cost reduction, and also add useful properties (for example, they increase the permeability of the paint surface to water vapor - this provides a "breathing" effect).
At the same time, the similarity of acrylic and acrylate paints is not limited only by some common name: these building materials have a common basis and a certain similarity in properties (they dry quickly, do not lose the intensity of the shade).
What is the difference between acrylic and acrylate paints?
Consider the main manufacturers of acrylate paints. The buyer should decide in advance which companies produce building materials for the price-quality ratio suitable for you.
The following companies are among the reputable manufacturers:
Tikkurila (Finland) ranks first in the rating of the best manufacturers. Finns are well versed in painting wooden buildings in the harsh northern conditions - their homes have always been distinguished by bright, rich colors. In Scandinavia, acrylate paints from Tikkurila are the quality standard for painting wooden facades.

Statistics say that in the Scandinavian countries over 80% of all wooden houses are painted with acrylate (and acrylic) paints. The company uses only high quality raw materials for the production of products.
If we talk about the shortcomings of "Tikkuril", then it should be admitted that the price of paint from this manufacturer is high.
The Canadian manufacturer "Forester" is also distinguished by a competent approach to the production of varnish-and-paint products for covering wooden houses located in the temperate zone. An excellent palette of colors, stability, unsurpassed brightness - all this can be said about "Forester". The company also offers a wide range of primers and other specialty materials for treating wood surfaces. The price for building materials from "Forester" also cannot be called democratic.
The German company "Dufa" produces high quality acrylate paints. Reviews of their products are consistently positive. For example, white paint produced by Dufa maintains its original whiteness for many years.

There are other less well-known European manufacturers that produce paints of consistently high quality; among them:
We can also recommend Russian companies that keep the brand and produce building materials of European quality level.
These are "Kotovsky paint and varnish plant", "Tex", "Olivesta".
Table. Characteristics of acrylate paints from major manufacturers.
|Manufacturing company||Country of origin||Characteristic|
|Tikkurila||Finland|| The paints are excellent for harsh climates. Wide range of shades.
Ideal for use on wooden surfaces. Provides super economical consumption. The downside is the high price.
|Dufa||Germany|| Good performance. Excellent coating of wood surfaces.
Minus - high consumption, high price
|Teknos||Finland|| Finnish quality. Easy to apply, forms a smooth matte surface. Economical consumption.
|Olvesta||Russia|| Decent quality. Constant updating of the assortment.
Affordable price. In terms of color characteristics, it is inferior to European manufacturers.
The process consists of several stages, consider the features each of them.
Purchase paint from the same manufacturer: even if the same color is indicated on the packaging of different manufacturers, this does not guarantee a complete match of the shade .
.. For example, traditional white paint made by different companies can have a noticeable difference.
Step 1. First of all, you need to estimate how much paint, primer and antiseptic (if necessary) you will need.
To do this, measure the area of the facade.
Step 2. Different types of ink are consumed in different ways, so here you will need to refer to the instructions printed on the packaging of the selected ink. There, the manufacturer always indicates the amount of paint that is spent on painting a particular surface. On average, modern acrylate paints are consumed in the amount of 300-400 ml per 1 sq.
m. However, these are average figures, it is better to clarify this moment in the instructions.
Scope of facade paints and approximate service life
Step 3. Multiplying the figure indicated there by the area facade, you get the total amount of paint.
Divide this figure by the volume of the selected paint can to obtain the number of paint containers you will need for the repair.
Step 5. Round up this number for stock.
You also need to check the ambient temperature suitable for painting with this type of paint.Modern paints can be used even at negative temperatures, but it is always better to clarify this in the instructions, and ideally, to carry out repair work at temperatures above + 5 degrees.
To paint a wooden facade you will need:
Tools for painting the facade
To make the paint smoother and better lay down and stay on the facade for a long time, it is necessary to prepare a wooden surface. The wall should be clean and free of dirt, so remove any peeling old paint and mold with a stiff brush or putty knife.
Preparing the facade of a wooden house for painting
Better use a primer of the same brand as the paint. Calculate the surface and cost in advance, although with a primer it is somewhat easier - here you do not depend on the danger of color mismatch.
If for some reason you cannot find a primer of the exact same brand, purchase a product from another manufacturer, but suitable for outdoor woodwork (plus the corresponding acrylate paint). Such preparation will improve the absorbency, give a smooth, beautiful surface after staining without uneven spots of a different shade.
Step 1. Remove dust from the surface.
Step 2. Putty all seams with a special wood putty.
Apply antiseptic (if there was a mold problem) along the wood grain.
Step 4. Apply primer (1 coat).
Applying a primer to the facade of a wooden house
Step 5. Wait until the primer is completely dry before applying paint.
Different manufacturers require different steps to prepare paint for application to wood. In this regard, general recommendations cannot be given, you should carefully read the instructions on the packaging. It may be necessary to dilute with water, but the volume of water should not exceed the amount indicated in the instructions.
Paint on a dry, sunny day. Do not carry out repair work in rain, extreme heat or high humidity.
When making repairs using acrylate paints, you will need to apply two to five coats (to ensure good resistance of the tree to damage from insects, mildew and rich color).When painting large surfaces, it is wiser to use a roller.
Painting the facade of a wooden house with acrylate paint
The sequence of actions is given below.
Step 1. Stir the paint thoroughly.
Step 2. Dip the roller in the paint, make sure it is completely saturated with the solution, then lightly roll it over the piece of material you don't need. This will help you get an even, streak-free finish.
Step 3. Apply the first coat of paint. It will take 3 to 4 hours for the surface to dry.
Step 4. Apply at least two to three more coats to maintain color stability and brightness.
When painting, start at the top level, then move down to the bottom areas.
