Acrylic paint for wood - versatility, attractiveness and durability. Facade paint for wood: oil-based, acrylic, silicone, alkyd compounds Is it possible to paint trees with facade paint
Despite the widest choice of synthetic finishing materials, a huge number of people still prefer wooden facades from clapboard, siding or blockhouse.
As you know, wooden surfaces suffer from moisture, temperature changes, fungi and insects. In order for the cladding to retain a presentable appearance for a long time, the surface must be treated. Properly selected coating will not only protect the wood from adverse effects environment, but also emphasize the natural beauty and uniqueness of the structure of the tree.
Long time the only coverage option wooden houses was an oil paint based on drying oil. However, now the range has expanded many times over. Acrylic antiseptic primers, various enamels, colorless polyurethane varnishes and much more have appeared.
To do right choice paintwork, should be considered:
- what type of wood is your facade made of;
- under what weather conditions the work will be carried out, in what climate the house will be operated;
- is it possible to paint over the facade before assembly - in parts - or is it necessary to work with the finished wall.
When re-processing, you need to know what paint was used for the primary painting. If you don't know, it's easy to determine. Scrape off a piece of the old coating - the oil paint will chip off, and the acrylic will roll up.
What paints for wooden facades exist?
The choice of coating for a wooden facade, first of all, is determined by the color scheme, your taste and budget. Before we go to the hardware store, first we will understand the concepts. What is enamel, varnish and paint, how do they differ from each other?
Dye is a suspension of pigments in various substances. It creates a uniform, opaque film.
Enamel- these are pigments in varnish, in the consistency of a suspension. Hard, opaque, textured film.
varnish- substances in organic solvents.

Now about each type of coverage in more detail.
Colorless varnishes and paints
Transparent coatings qualitatively emphasize the natural structure of the tree. The advantages of such a coating, in addition to external beauty, include excellent vapor permeability, due to which such paint dries perfectly on the surface of wood. And thanks to ultraviolet filters, the wood does not fade in the sun.
On a note! Renewal of such coverage will be required not earlier than in a few years. When repainting, it is not necessary to remove the old layer.
The disadvantage of such coatings is the rather high cost.
Water-dispersion paints and varnishes
This type of coating is one of the most popular in the world. Water-dispersed paints occupy about 80% of the entire world paint market.
The advantages of such coatings are color fastness, resistance to moisture and sun. A breathable film is created on the treated surface, thanks to which it is very comfortable to be inside such a room.
The downside of the coating may be unsuitability for work with sub-zero temperature. Due to the presence of water in the composition, under the influence of frost, such paint exfoliates. In addition, such a coating is less durable, re-treatment may be required after about 4 years. These are mid-range paints.
Opaque enamels (traditional oil paints on drying oil and close analogues)
Such enamels based on organic solvents used to be extremely popular. Recently, they have been seriously supplanted by water-dispersion paints.
The main reason for the decline in the popularity of traditional paints is increased toxicity. Who among us at least once in his life did not feel bad, inhaling paint? In addition, such paint is more flammable. It is impossible to call opaque enamels durable. When exposed to moisture and temperature changes, the facades quickly lose their presentable appearance, and the coating cracks.
The advantage of traditional colors remains low cost. These paints are among the cheapest on the market.
Obtained by mixing a binder - alkyd resin, coloring pigment and solvent (kerosene, white spirit and others). Sometimes the mixture includes a desiccant that affects the drying rate, thixotropic (to avoid spreading) and antifungal additives. This coating is water resistant, dries quickly and does not turn yellow, unlike some other coatings.

How to paint the wooden facade of the house yourself?
We will need:
- work gloves;
- protective mask;
- wide brush;
- small brush;
- rag;
- grinder and sandpaper;
- drill and disc brush for drill;
- spatulas;
- paint stirrer.
First, let's find out if we are going to repaint the old, peeling wall or process a new, unpainted facade? Those who are painting a new facade can skip the first step in our instructions because we will start by removing the peeling paint.

Step 1: Removing Old Paint
The most important thing when repainting an old wooden facade is the quality removal of peeling paint. If you leave dangling, chipping pieces of old paint on the wall, they will soon fall off, taking some of the new coating with them. And all the work will go down the drain.
There are several ways to remove old paint. You can clean the surface with a scraper or a stiff brush, then rinse with a special solution or water under pressure and dry thoroughly. Can you warm up old paint with a building hair dryer and scrape off with a scraper or spatula. The method you choose depends on your capabilities and the condition of the old coating. The main thing is that as a result of pre-treatment, the surface becomes homogeneous, smooth and dry. No loose paint, protruding lint or smudges.
On a note! For the convenience of further work, it is necessary to remove from the facade drainpipes, other elements that protrude and may interfere with work, and, if possible, seal the windows with a film.
Step 2. Sanding and putty
For best result both old and new wood are best sanded with grinder or a disc brush for a drill.
If there are gaps and irregularities, they must be repaired with wood putty using a spatula. For wooden facades, oil or adhesive putty is best suited. Due to its composition, it better tolerates moisture and the adverse effects of the environment. Apply a thin layer of putty to damaged areas and dry thoroughly before further processing.
Step 3. Surface treatment with a primer or antiseptic
Any wooden surface- it doesn’t matter, old or new - it must be treated with an antiseptic or primer. The main mistake of the majority is precisely that the priming stage is omitted. It is understandable, because often a primer or antiseptic is more expensive than paint. However, it is the priming of the walls that guarantees the perfect result at the end.
Modern antiseptic impregnations not only protect wood from corrosion, insects and fungi, but also stop the beginning process of wood decay (which is very useful in the case of restoration of old walls).
New, unpainted wood surfaces also need to be primed. Usually manufacturers paintwork materials produce primers that are ideal for the type of paint you choose. That's why The best decision- purchase a primer from the same manufacturer as the paint you have chosen. For example, if you are painting a wall with Tikkurila Pika-Teho paint, Tikkurila Valtti Pohjuste primer will work.
The primer or antiseptic is applied with a brush in one layer, carefully rubbing the composition into the wood. After coating with a primer and before painting, the wall must be dried. Different types of primers dry different amount time, see the drying information on the packaging of your product.

Step 4. Coloring
After the surface has been sanded, primed and thoroughly dried, you can start painting.
Important! pay attention to weather where you plan to work. If you are going to process a new facade and it is possible to paint it in parts, it is better to paint indoors. If you need to paint finished wall– Carefully study the weather requirements on the paint package.
For various kinds paints climatic restrictions may vary. Manufacturers agree on one thing - do not choose wet, rainy weather, scorching sun and heat for painting, or early morning when the facade is not completely dry from dew. A dry, medium-cloudy day is best for such work. Humidity - no more than 50%, air temperature - from +5 to +20 degrees. It is recommended to start work no earlier than 10-11 am.
Before starting work, the paint must be thoroughly mixed with a paint mixer or a stick.
Different paints require different amounts of applications. On average, the paint is applied in 2-3 layers, carefully drying each of them. Sometimes the first layer is diluted with a primer. For exterior painting of the house, a wide, dense brush with fairly stiff bristles is best suited. Apply paint in a thin, even layer, moving along the fibers.

Important! The drying time of each coat of paint may vary depending on the type of coating. At various manufacturers paint can dry from 2 to 24 hours.
A well-painted wooden facade is a beautiful appearance of your house for 10 or even 15 years. The main thing in this process is to carefully approach the choice of materials, carefully follow the instructions and take into account climatic conditions.

Requirements for facade paints, naturally presented by buyers: durability and environmental Safety. They must also retain color, withstand significant temperature changes, and have attractive natural shades. Quality is ensured not only by the manufacturer, but also by compliance with the rules of staining different surfaces. For example, facade paint on wood should be applied to a layer of adhesive alkyd primer. As a standard, buyers use antiseptic primers, but they only provide protection for the wood, but not adhesion of the layers.
That is why even good facade paint cracks and peels off within 2 years after application. At the same time, manufacturers guarantee the integrity of the coating for decades. To achieve this, it is necessary to follow the application technology. Many years of experience accumulated by manufacturers allows us to create the best paint and varnish materials for the facade. The division into types of surfaces that they paint has a positive effect on the result, since the degree of absorption of different building materials is different.
How to paint a wooden facade?
The choice of paint depends on the desired result: it completely covers the wood, creating an opaque layer, or leaves the wood structure visible. In the first case, acrylic or oil paints are used, in the second - tinted antiseptics or varnish.
Modern paints are distinguished by better resistance to atmospheric precipitation. Oil varieties choose, as a rule, light shades, as they fade over the years. This does not affect performance, only the gloss changes, losing its original appearance.
Acrylic paints are elastic and breathable, their formula allows you to maintain a balance of moisture and dryness of wood. It can be used for both facade and internal works, and it can be applied to old surface. You just need to make sure that it is dry and correctly prepare the surface. Alkyd enamels are also used for painting wooden facades. They provide a brilliant sheen or satin (matte) surface, penetrate well into the pores of the wood, preserving its natural properties.
The color palette of almost all facade paints allows you to give the surface any shades, to realize original design solutions. Elasticity allows them to stretch and shrink with the wood, protecting them from cracking. This property is important for painting only erected buildings, which will shrink within a year.
Any facade paint is applied after special preparation of wood. If an adhesive primer is not used, the adhesion of the primer to the wood is ensured by sanding. To do this, use a grinder or sandpaper with fine grain. After grinding, the surface is cleaned of wood dust with a wet brush.
When choosing a tinted antiseptic, one should take into account the presence in the composition of additives not only against decay and bugs, but also protecting against UV radiation and moisture. They prevent the growth of mold, algae and maintain the freshness of the shade. Tinted antiseptics are divided into the following varieties:
- glazing,
- covering.
The former leave a transparent layer, only shading the wood. The latter do not allow you to see its pattern, structure, as they create a dense layer.
Qualitative characteristics do not deteriorate in any type of antiseptics, the transparent layer protects the tree as well as the dense one.

The paint is applied by hand with a wide brush along the natural pattern of the beam or log. The ends of the tree are treated with a special sealant for water based. It does not allow moisture from the street to penetrate into the pores of the tree, while maintaining its ability to breathe. The second layer is applied after the facade has been treated with an abrasive sponge. It creates microscopic roughness, which ensures high-quality adhesion of the layers.
It's important to know what's new wooden house can be painted immediately if it is built from glued beams. Other types wooden materials require natural additional drying. The same applies to the old wooden house. You should make sure that the log or timber does not contain excess moisture. Work is carried out at positive temperatures in dry weather.
