Painting a house will completely transform its design. In comparison with other types of reconstruction, you can paint it in a short time and for little money. Paint will also protect the house from negative external influences. With proper painting, the coating can last about fifteen years, subject to consistent work and the use of high quality materials.
How to paint the house so that it will delight you with an impeccable view for a long time? If you decide to make repairs yourself, you have to stock up on great patience. First you must prepare the walls of the house for painting.
Preparatory work
How to paint a wooden house? Before painting any external surface, thorough cleaning is necessary to remove dirt, cracked paint, get rid of mold. A hose or garden sprayer and brush can be used for this work. It should not be too tight. Use water to quickly remove dust.
Old paint may contain lead, so be careful when cleaning it: protect yourself and the environment from toxic dust. Before starting cleaning work, be sure to put on a mask or respirator, lay a tarp or film in front of the house. Cover nearby plants.
Grinding walls is an important stage of preparatory work
After the wall is cleaned of peeling paint, it must be sanded. The sanding process is the most time-consuming of all home painting work. For it, several types of sandpaper of various grain sizes should be used. Manual cleaning of the paint is an exhausting task, you can use an industrial hairdryer to speed up the process, it will help soften the paint.
Specialists conduct it using a grinding machine, on which high-density discs are mounted. High-quality grinding removes exfoliated pieces of wood and makes the surface smooth, without any roughness.
The final stage of the preparation of the walls of the house
Before painting an old wooden house, you need to carefully process it. If you notice mold or blue on the surface, immediately remove it using a special tool.
The resin can be removed with a metal spatula. Seal all small cracks and dents with two-stage curing epoxy. Hats of nails, screws and other metal parts are best covered with a primer for metal.
After completing the preparation process, do not start painting work within ten days.
How to carry out protective treatment
How to paint the facade of the house? Before painting, it is necessary to treat the walls with special compounds. There are several types of formulations:
- penetrating - penetrate the structure of wood;
- surface - form a protective film;
- thermal - change the properties of wood.
Penetration treatment is more popular, it is carried out using compounds called impregnations.They protect the wood from moisture, mold, microorganisms and fire.
There is a decorative impregnation; after its application, the wood can not be painted. It emphasizes the texture and gives a certain shade to the wood. If you were going to paint the house from a bar, decorative impregnation will be enough for him.
Often, impregnations also act as primers, they improve adhesion and reduce the consumption of paintwork.
If the surface is well cleaned of paint, you can not prime the walls. To determine the strength of the paint remaining on the wall, stick a transparent stationery tape on it and with a sharp movement tear it off the wall. If pieces of the remaining paint did not remain on the scotch tape, the wall is ready for painting.
You can prime the walls with a primer, it protects the wood well, but this coating dries for a very long time. The best option for outdoor work is the use of a primer recommended by the manufacturer of facade paint. Therefore, first select a paint to repair the facade of the house.
What paint to choose
How to paint a wooden house beautifully? To do this, you need to choose the right paint. Before, wooden houses were mostly painted with oil paints. Now there are innovative tools for painting the house:
- alkyd
- acrylic
- covering
- textural.
Alkyd
For outdoor decoration, alkyd compounds are more suitable - resistant to weathering. They are in high demand due to their low price. When they dry, a thinnest film is formed, but the coating is short-lived, since alkyd paint does not penetrate deep into the wood. One layer dries within ten hours.
Acrylic
These paints protect the wood from moisture penetration, are not afraid of low temperatures, and preserve the “breathing” properties of wood. If they paint the house outside, the coating will be resistant to mechanical stress.
The polymer emulsion, on the basis of which acrylic enamel is made, does not oxidize in air, so it does not lose its gloss for a long time. The house painted with acrylics for several years looks like new.
Covering
Finish wood preservatives belong to covering paints. They do not contain "heavy" chemistry, do not have an unpleasant odor, and are safe for health. Covering paints are evenly applied, do not fade for a long time, allow the wood to breathe, emphasize its texture. They are resistant to climatic influences and protect wood well. The paint dries quickly, so several layers can be applied during the day.
Textural
Texture paints are diverse. They are not yet as popular as acrylic and alkyd, as they appeared recently. These coatings give the surface any texture and texture. Texture paints are easily diluted with color. They well hide irregularities and are easy to apply. Due to the affordable cost of paints and the convenience of working with them, it is easy to realize original design ideas.
All packages contain information about the consumption of paint: the number of liters that will be spent on painting one square meter.
Tips from professionals for quality home painting
How to paint the facade of the house with your own hands? Experts recommend:
- surfaces with old paint must be cleaned and sanded to give the entire treated area the same absorbency;
- mix the coloring compound thoroughly to obtain a uniform color;
- apply paint only on dry and clean primed surfaces;
- check the color on a small surface area before painting. If it is too dark, you can add a little color. The intensity of the shade depends on the quality of the wood processing and the number of layers;
- apply finish coatings on the walls of the timber from the outside in two layers;
- paint only in cloudy, warm and calm weather.You should not paint under the scorching sun or, if weather forecasters promise rainfall.
How to apply paint
The choice of tools for painting a house is determined by the consistency of paint, the surface to be painted and the qualifications of the workers.
Most professionals use spray guns, because with their help you can quickly paint a timber house. But in inexperienced hands, a powerful sprayer will leave strong streaks and paint not only the house, but everything around: a drain, a roof, windows, bushes, pedestrian walkways, cars.
If you have not yet acquired skills with a spray gun, you can paint your house with a roller or brush.
Paint the walls with a roller
Walls with a smooth surface are painted with a short-nap roller or brush. If you are painting an old house made of wood, it is better to use a roller to reduce paint consumption and speed up painting.
The roller absorbs a lot of excess paint. It is better to squeeze it on a grid stretched over the frame.
Getting started, bring the roller to the surface, and without much pressure, slide it along the wall. Drive the roller in the vertical direction first, and then in the horizontal direction. During operation, the force of pressing the roller should be unchanged. Shade the paint thoroughly and do not leave gaps.
Painting a house with textured paints
If you paint with textured paints, you can buy a texture roller for them. With its help, various patterns or imitation of natural material, for example, brick, are created on the wall. This allows you to completely change the design of the walls.
To get a pronounced texture, the roller needs to be moistened as much as possible. It is better not to leave the wall unfinished; after drying, the joints and joints will be visible on it.
If you decide to paint the house with a brush, do not take a brush with long bristles, it is usually used when you need to paint a brick house. The walls of brick are very embossed, so it is difficult to paint them with a roller.
To paint the facade with a brush at a height, you will have to install construction scaffolding.
Doing home painting yourself is worth it if you have enough free time and patience. You can order the preparatory work from professionals, and paint the walls yourself to get a high-quality design of the facade of the house.
