Bath walls need protection from temperature extremes, exposure to precipitation and ultraviolet radiation. In order to maximize the resistance of the walls to negative factors, to give aesthetic appeal and extend the life of the bath, it is important to choose the correct coloring composition and paint the surface correctly.
Means for outdoor painting of a bath
When choosing materials for outdoor painting of a bathhouse, it is worth considering the surrounding climate. The coloring agent must be moisture resistant, fireproof and resistant to mechanical stress. The composition for painting a bath outside must provide reliable protection against darkening, decay, and UV radiation. Paints are able to penetrate deep into the wood, they need to be painted on the surface every 4-5 years. The varnish coatings form a kind of water-repellent film that protects the wood from burning out.
Selection of paint for painting a bath
When choosing paint for covering a log house, you should pay attention to their types and properties:
- Oil paint … Extremely sensitive to sunlight. It is rarely used for painting wooden baths. Price - from 400 rubles per liter.
- Alkyd paint … It happens on an oil basis and lacquer. For painting a log house, it is better to use enamel paint on a varnish basis. Price - from 300 rubles per liter.
- Emulsion paints … This class includes water-based, water-dispersible, acrylic compositions. The last two options are the optimal solution for the exterior painting of the bathhouse. They allow the wood to "breathe", do not contain harmful chemical solvents and are well diluted and removed with water until they polymerize on the surface. They are not afraid of the sun's rays, these paints are quite durable. The cost of 1 liter is from 650 rubles.
Important! Silicate paints and glue paints are not suitable for outdoor woodwork.
The choice of varnish for covering the bath
If you decide to preserve the natural pattern of the tree as much as possible, then you should opt for varnish coatings, which are of several types:
- Alkyd … They are used for external and internal works. Extremely durable and moisture resistant. Of the minuses, you can single out a long drying time. Price - from 700 rubles per liter.
- Acrylic … It is believed that varnishes of this type are the most environmentally friendly. They are fireproof, durable and flexible. They keep the original appearance of the tree for many years. Price - from 200 rubles per liter.
- Epoxy … This category of varnishes is waterproof, resistant to mechanical and chemical factors. They dry quickly and are widely used for outdoor finishing works. From 350 rubles per 1 liter.
- Polyurethane … These varnishes are rightfully considered one of the most popular. Very resistant to abrasion, mechanical damage, chemical attack. A wide range of these varnishes allows you to choose the right one for outdoor wood finishing. Cost - from 1200 rubles per liter.
The most common mistake is using parquet varnish for painting. But it forms a too hard shell and interferes with the natural processes of wood drying. Paints and varnishes for the exterior decoration of the log house of the bathhouse are now widely represented on the market by brands such as Tikkurila, Teknos, Akzo Nobel, Belinka, Rogneda, Senezh, Empils and others.
Preparation for painting the bath
To begin with, it is important to take into account the shrinkage of the logs. The surface can be painted only after the moisture mark has dropped below 20%. Before painting, the surface must be thoroughly cleaned of dust in all cracks. You can also wipe them with a damp cloth. There should be no lint on the walls.
After cleaning, the logs are covered with a fire retardant and primer antiseptic. Each composition is applied in two layers after the previous one has completely dried. After covering the walls with protective products, leave them for two to three weeks for even distribution and impregnation. However, if you have purchased a coloring composition that already contains antiseptic substances, additional protective treatment can be omitted.
If you decide to caulk the bath with synthetic sealants, then choose special compounds that can then be painted. Also, prepare for the fact that the color you chose on the plank when buying paint, and the color of the frame, will differ from each other.
Technology of external painting of a wooden bath
The log house is painted not only after construction, but also to return the aesthetic appearance to the old structure. Before starting the process, decide on the tool. For coloring, you can use a brush, roller or spray. If you are painting old wooden walls, then first you need to treat them with a special bleach.
Rules for painting the walls of the bath with paint
Outdoor paints are usually chemically based for maximum protection against external influences. For uniform and high-quality staining, we perform work in the following sequence:
- We close the areas that are not required to be stained.
- Next, you need to make sure that the caulking material is tightly packed into the cracks.
- Apply the first coat of paint with a brush, roller or spray. We paint the walls by holding the spray gun at a right angle and moving it evenly. Let the paint dry.
- We carefully grind the painted surface from the appeared villi.
- If painting is done with a spray gun, then at the bottom we change the angle of inclination to completely cover the entire surface with paint.
- Apply another coat of paint.
When working with a spray gun, it is necessary to apply 3-4 layers for uniform coloring. If the walls are painted with a brush, then one or two layers will be enough.
Note! The most popular among the "old-fashioned methods" is painting a bath with a decoction of oak bark. It gives the wood a dark, transparent tone. It should be borne in mind that such methods are incomplete. They cannot provide reliable protection against negative factors at the same level as modern paints and varnishes.
Features of painting a bath with varnish
Walls outside are painted only in length. The ends of the log house are not varnished. They must be thoroughly impregnated with a protective compound and (optionally) painted with acrylic impregnation in 4-5 layers. Opening the walls with varnish, we adhere to the following instructions:
- When choosing a tool, keep in mind that after painting with a brush or roller, the surface acquires a matte texture. At the same time, spray painting gives the walls a glossy look.
- Apply the first coat of varnish. For this, it is better to use a spray bottle. After such a coating, the irregularities will be less than after working with a brush. Do not forget to cover items that do not require painting with a protective sheet.
- We sand the surface after complete drying.
- We open the wall with a second layer, paying special attention to the seams and corners.
- Try to keep the spray gun at approximately the same distance from the surface during the entire process.
Please note that the inside of the bath is not painted. It is only permissible to treat surfaces with antiseptic compounds, fire retardants and a special oil that prevents the wood from drying out. Watch the video on how to paint the bath outside:
By adhering to the above tips and recommendations for external painting of the walls of a wooden bath, you can effectively protect the structure from dampness, mildew, mold and other influences. Step-by-step instructions will help you understand the technological process and complete the work yourself.
