General information about facade painting
Painting a wet or dry facade is the easiest way to change the appearance of a building, allowing you to radically change its design.
Considering the unlimited color range of paints, we can say that they are the most effective tool for transforming the appearance of wooden and other buildings.
To paint facades, it is recommended to use paint of a ready-made shade or mix several different paints to obtain the required color scheme.
The facade of the house is painted using a regular brush or a special spray gun, which can be purchased at any hardware store.
Tips for choosing colors
We recommend taking into account some criteria when choosing a color:
- the color of the walls and roof should be combined, therefore, if the color for the roof has not yet been finally decided, then painting the facade of the house in pastel colors over plaster is the best option for the walls;
- if the roof is dark in color, then the outer walls are painted in light colors;
- to make the house look more elegant, more dynamic, use two shades (for openings - lighter colors than for walls), the reverse combination is used less often, only after consulting with the designer;
- parts of the facade are distinguished either by the structure of the coating or by color (two means together are too much);
- you should take into account the style, as well as the design of the local area, its lighting, and the type of plants.
Advantages and disadvantages of facade painting
Painting buildings with foam or other finishing materials offers many advantages over unpainted buildings. First of all, properly carried out work performs a protective function, protecting the casing from many negative factors. The walls of the building will be protected from:
- damage;
- moisture;
- rust;
- pollution.
Painting facades significantly increases the service life of the building. An additional advantage of this technology is the ability to apply paint yourself, if you have the desire and basic construction skills.

Classification and characteristics of facade paints
Alkyd paints
You can paint the facade of a house, no matter whether it is wet or dry, using oil-based (alkyd) paints. The presented paint and varnish products are made on the basis of alkyd resins diluted with drying oil. The technology is traditional, but is currently considered obsolete. Many, however, note the undoubted advantages of this paint and varnish product.
- Price. The costs of finishing a brick building or finishing foam when using alkyd compounds are low. The price of the product is significantly lower compared to other paints and varnishes.
- Vapor permeability. If the paint is applied correctly, it makes it possible to obtain a gas-tight surface, which is worth considering when working with lime plaster.
- Moisture resistance. The presented type of finishing for wooden and other buildings protects the finishing well from high humidity.
Before painting a wet or dry wooden structure, it is worth carrying out a number of preparatory work. For better adhesion, it is necessary to create the necessary base on a wooden surface.
There are also disadvantages that need to be noted.
- Polymerization . The use of alkyd substances for painting facades is characterized by long drying times - up to three days.
- Fragility. The top layer of paint quickly becomes brittle and bursts when exposed to oxygen and sunlight.
- Insufficient adhesion. When applying alkyd paint, it is typical for wooden and other buildings that it does not adhere well to the surface.
Rubber paints
For wooden and other surfaces, latex-based paints are the best option. This type of paint coating is modern and high-tech.
The numerous advantages of rubber paints for foam and other surfaces are noted.
- Elasticity. The presented material is considered the most elastic compared to analogues. It makes it possible to restrain the expansion of microcracks on the walls.
- Moisture resistance. If you paint the facade of your house with rubber paint, the walls will be reliably protected from corrosion and moisture.
- High adhesion. The presented type of product fits perfectly on any material, from foam plastic to wood.
The only drawback of this finishing material is the price. Painting facades with latex paints is the most expensive.
Before carrying out work, you should choose the type of paint that best suits the type of wall surface material, and only then act strictly according to the instructions
Acrylic paints
For wooden and other surfaces, acrylic paints based on similar resins, for example, “Olympus,” are actively used. They are presented in the store as water-dispersed solutions. A cheaper option is to use acrylic copolymers.
They are valued for their many benefits.
- Elasticity . After finishing facades with Olympus paint, surface shifts of up to half a millimeter can be prevented.
- Gas permeability. When performing work in accordance with SNiP, metal elements do not rust or oxidize.
- Durability. Compliance with SNiP when carrying out painting work makes it possible to obtain a surface that will last at least twenty years without changing the structure.
- Strength. The paint can withstand moderate impacts.
- Moisture resistance. The product has good resistance to high humidity, so it reliably protects the house from damage in humid climates.
These paints also have disadvantages.
- High price. When painting a surface made of foam or other porous coatings, you will have to spend money.
- Low gas permeability. Paint should not be applied to breathable materials, as they have low vapor permeability.
Selection and application of paint in accordance with SNiP is the key to the durability of the facade and ensuring a good appearance of the building, regardless of external conditions!
Calculation of the volume of materials
The list of materials may differ depending on the type of facade and its design. In some cases, in addition to standard preparation and painting, it may be necessary to dismantle old coatings, plastering and much more.

Technology of painting different types of facades
Compositions for painting brick buildings
How to paint the facade if it is brick? In this case, the choice of paint plays a decisive role. There are compositions on the market designed specifically for brick surfaces.
The technology for painting a facade assumes that the paint meets GOST and a number of requirements - it is resistant to moisture, sunlight and alkaline agents, and remains porous when dried. Olympus products will not be suitable in this case. Brick can be improved using silicone, lime and latex compounds.
Brick can be refined using organosilicon, lime and latex compounds
Organosilicon paints form a heat- and moisture-resistant coating on the brick, which has good water resistance. The presented compositions are suitable for painting facades due to the fact that they are able to protect walls from temperature changes and negative environmental influences. But the cost of the compositions is quite high, so the choice often falls on less expensive lime mixtures.
When carrying out work in accordance with SNiP, lime paints are also well applied to bricks. The composition on the wall surface looks attractive, while it is environmentally friendly and safe for human health. You can apply it yourself, even with little construction skills. Of the minuses, it is worth noting that the mixture begins to peel off quickly after drying.
Acting in accordance with SNiP, many apply latex paints, which have good decorative characteristics, to the brick. When the composition is applied to the walls, the facade becomes reliably protected from the harmful effects of the environment.
It is important to know that before applying paint, brick walls require careful preparation.
Preparatory work for painting a brick facade
First of all, you should prepare the surface of the facade. It is worth carefully inspecting the brick for salt stains that interfere with good adhesion of the paint to the structure. Stains are removed with a wire brush and detergents.
According to SNiP, walls should be free of dust to prevent paint peeling in the future. It is recommended to wash walls with soap and water. Lime and mold are removed using special solutions.
Before painting the walls, they are primed twice. It improves the adhesion of paint and building surfaces. The primer should be resistant to alkaline environments. Walls can be painted only after they have dried; chalk glass protection is required when painting facades. A spray bottle will help to cover the walls well.
Considering the unlimited color range of paints, we can say that they are the most effective tool for transforming the appearance of wooden and other buildings
Painting wooden buildings
Before painting a wet or dry wooden structure, it is worth carrying out a number of preparatory work. For better adhesion, it is necessary to create the necessary base on a wooden surface.
- Take a garden sprayer and a soft brush to remove the dust.
- If there is mold, it is removed with special preparations.
- Resin is removed from wooden surfaces with a metal spatula. The place where it was is treated with varnish for knots.
- Nails and screws are coated with a metal primer.
- Upon completion of the above work, the wood should rest for two weeks under film cover.
You can paint the tree yourself with oil, acrylate paints or antiseptics. The latter option is characterized by high penetrating ability - up to 7 millimeters.
Acrylate and oil paints absorb well, but dry slowly. The composition should be updated after 6–10 years; for antiseptics, updating is required after five years.
The best paint for wood is “Olympus”, and when working in the cold season, it is important to use specialized compounds.
To paint a wet wooden facade, no special skills are required, but there are some nuances that must be observed. First of all, it is necessary to apply a primer; it is better to apply the paint in two layers and on a dry surface. To ensure the same shade of paint, it should be stirred periodically.
Rubber shades
As a representative of the new generation of paints, tints are very popular among people.
This rating indicator was achieved due to the following advantages of the material:
1. They do not deteriorate when exposed to various weather conditions, namely sudden changes in temperature and high humidity. This allows them to be used in both northern and southern regions.
2. High-quality adhesion to the base allows you to apply colors to any surface. An exception may be some representatives of wooden surfaces. The application of rubber material creates a kind of coating for the building, reminiscent of a “rubber coat”.
3. Long service life is guaranteed by the manufacturer. It is determined to be approximately 10 years, but according to consumer reviews, it can exceed the warranty period several times.
A large palette of shades will allow you to create an external facade design to suit every taste. Despite such positive characteristics, rubber colors also have disadvantages in their use. The disadvantages include the fairly high cost and a limited range of manufacturers. Another disadvantage is the complex application technology, the violation of which will lead to peeling of the material and loss of attractiveness of the building facade.
Painting the facade of a house with your own hands (video)
So, you can improve the facade with Olympus paint or other paints and varnishes. Before carrying out work, you should choose the type of paint that best suits the type of wall surface material, and only then act strictly according to the instructions. Then the facade of the building will look beautiful, and its service life will be long.
