Despite the huge selection of modern building materials, wooden buildings are still relevant today. This is an environmentally friendly material that, unfortunately, is subject to destruction under the influence of weather factors, humidity, and insects. Facade paints on wood for outdoor use will help preserve the wooden structure, give it a well-groomed look and various designs.
Features of the
Untreated wooden surfaces darken over time, crack, and become moldy. Protective paintwork for wooden facades extends the life of the building. Country houses, baths, country houses and other wooden structures after finishing with facade paint remain beautiful and presentable for many years. The range of colors of these paints amazes the imagination and allows you to embody any fantasy of the consumer.
The production uses the latest technology to improve the quality of paint, making it safe for the environment and for humans.
If you choose a paint for a wooden facade, then you must take into account its technical characteristics:
- frost resistance;
- moisture resistance;
- high vapor permeability;
- good adhesion (adhesion to the surface);
- the durability of the coloring pigment;
- counteracting the formation of fungus and mold;
- abrasion resistance.
The facing coating is different. The usual oil paints are a thing of the past - the price is too high for poor quality. They include drying oil, fillers and color pigments. The toxicity of this kind also makes them a huge disadvantage.
Oil products do not have the quality of protection against weather conditions and require repeated application. In addition, their composition is the most flammable.
The advantage of the oil option is the density of the product, into which dust and grains of soot from the roads will definitely not eat. It is applied very simply, does not require additional skills. To choose this type of coverage, you need to know the designations on the banks. The letters indicate the main raw material, for example, PE is a polyester resin. The first number indicates the area of application:
- 1 - this is for external work;
- 2 is for interior decoration.
There may be a second number, it already shows the type of binder:
- 1 is a natural drying oil;
- 2 is oxol.
To replace them, frost-resistant alkyd-based mixtures appeared, but even in winter they dry for a very long time. Alkyd resins in their composition must be diluted with linseed oil, kerosene or turpentine, which is also a minus in terms of toxicity. However, it is this feature that really protects against bugs and moisture. A thick film forms on the drying surface, which protects against external factors.
It is necessary to carefully approach the issue of choosing an alkyd paint. Its high price is due to the natural ingredients in the composition. Each element must be certified and validated. Modifications with chemical solutions can cause accidents, which is why alkyd paint is usually not used at home.
However, with proper safety training, the use of alkyd paints is not a concern. The main thing is to dilute the product in the correct proportions, according to the instructions in the package.
Water-based products are durable and harmless, which dries very quickly. The composition is 100% non-flammable. The coating will not fade over the years, and to restore brightness, you just need to wipe the walls with detergents. Water-based facade paint has a high level of protection against weather conditions, does not contain a single toxic element for human health, and is also characterized by ease of use without requiring additional skills.
The basis of water-dispersion paints is a physical process. Mineral paint is a variety of them. It is based on lime or white cement. It is more suitable for interior work.
For the treatment of the external facade, it is worth using a silicate version of the water-based emulsion principle of operation. The sodium or potassium binder in the composition gives the highest service life (more than 15 years). But the composition is unstable to temperature extremes.
Frost-resistant and not so capricious option - these are acrylic materials … They are suitable for any job. Wear is not a hindrance for such paint. She perfectly tolerates heat and dampness, lasts more than 7 years.
Synthetic latex can also be the base of the product. The material is very flexible, which helps to hide cracks and unevenness, for example, due to poor priming experience.
Silicone treatment is suitable for homes located in humid continental regions. The walls will not fade or fade, the color will remain bright and even, and the coatings cracked from rain can be filled with the remaining paint, because the structure of the composition does not leave visible traces of reapplication.
Using this short list, you can already easily choose the appropriate option for the wooden facade of the house. Latex, silicone and PVC products have advantages such as brightness and saturation, but they must be constantly stirred during the painting process. Here you will need additional help from a specialist or a thorough study of the issue of operation: choosing the right brush, special containers, mandatory pre-treatment and an air temperature not lower than +5 and not higher than +21 degrees. The water-based mixture is more expensive, dries in about 2 hours, evaporates and leaves only pigment in the walls. The disadvantage of this option is a large expense.
The principle of work of enamel and varnishes is different. It is the method of working with them that becomes decisive in the choice of paints. Lacquer products are smoother and shine, enamel products require the use of a solvent and are more resistant to various temperatures.
The price of paint depends on the manufacturer, the coverage area, and also on the function it performs. For example, to paint an area with Tikkurila Ultra Classic, which protects against frost, it will take about 1 liter of material, which will be about 922 rubles.
And if you use paint from the same manufacturer, but with the function of leveling the surface of Teho oljumaali, then for 1 liter you will have to pay about 1000 rubles. On average, about 300 grams of the composition is used for 1 m². For example, if you need to paint 10 m² of the facade, you should buy at least 3 liters of the product.
Consumption depends on the structure of the product. Sometimes it is necessary to apply two or three coats for the surface to be completely saturated with pigment and acquire a beautiful color. Acrylic paint is consumed several times less than water-based paint. For 1 m² you need about 150-200 grams. The consumption of products depends on how catchy and bright the external decoration of the facade should be.
Tips & Tricks
It is important to understand what kind of wood the house is built from, in what weather the painting will be. Measurements of the area to be covered will also guide the selection of products. You should pay attention to the instructions from the manufacturers.
Old walls, even after sanding, can have jagged edges, which will affect the final result of the renovation. You can smooth them out with sandpaper. Then walk with a spray gun with a primer and you can start painting.
The most important thing here is to make sure that the surface is completely dry after priming and to carry out the work in good weather.
Paint is a chemical. It is imperative to protect your eyes, skin and respiratory tract. In the store, along with materials and tools, you need to buy a respirator and goggles. Manufacturers often recommend buying construction fabric gloves, but medical ones will be a more convenient option.
When repaired again, the surface must be cleaned. It is better to use special means so as not to injure the walls. It is imperative to find out the type of the previous product. All mixtures will be smoothly coated on the previously painted area.
In order for the paint to "lay down" ideally, you need to prepare the walls. The priming step cannot be ignored. Pre-treatment should include a primer and an antiseptic. It is important to guess the moment when the first layer of the primer has already dried up and only after that it is taken for the second. Antiseptic prevents corrosion, which is very important for old premises. It is better to purchase the primer from the same company as the material for the work. If you purchased Tikkurila Pika-Teho products, then the Tikkurila Valtti Pohjuste primer is ideal.
Consideration should be given to material consumption. The choice of brush depends on the consistency of the paint. Short-haired tools are suitable for smooth walls, while long-haired tools are suitable for textured walls.
Usually brushes are made from artificial fiber or natural hair. When working, it is better to use the latter option as it is suitable for any type of work. It is better to buy a brush with a width of 100 mm for working with the external facade of the house.
A brush is good, but rollers are even better. The wide roller is ideal for painting large areas. These tools are also handy for painting rough walls, such as re-painting. It is better to purchase a roller made from natural materials.
Don't throw away leftover materials. It will be irrational. When stored properly, the paint will be recyclable. The most important thing is to clean the edges of the container, otherwise you won't be able to open the can later. Do not store the mixture in a room with large temperature fluctuations. It is important to choose a dark and dry environment. Do not place the container on a concrete floor to prevent corrosion. If rust particles get into the paint, it will not cover the wall with a smooth layer. A film may also appear on the paint, it must be carefully removed. If it gets into the main mixture, it will give unpleasant lumps.
It is important to save the sticker so that later you do not need to remember the color, company and manufacturer.
The best paint is the one that fits the bill. Manufacturers such as Alpina and Belinka are heard by Russian buyers. Neomid, Tikkurila and Zobel are moving into a higher price category, products from Dulux and Teknos are cheaper. The finishing of the outer coating implies the use of varnishes for stronger surface protection. Usually Pinotex Natural, Tikkurila Valtti Color and Valtti Color Satin, Belinka Toplasur or Lasur products are chosen.
The most popular manufacturers of wood facade paint are Tikkurila, Forester and Dufa. The products really correspond to European quality, and also attract attention at an affordable price. Domestic manufacturers Olivest, Tex and Stroykompleks are not inferior in quality, but they are much cheaper.
To create a denser coverage, it is worth looking at oil options such as Tikkurila Teho, Finncolor Forest, Dulux Domus. Water-dispersion paints are presented by such options as "Profi Tex", "Optimist", Braska Facade and Dulux Domus Aqua.
Osmo materials, made from natural materials, are suitable for all criteria for painting wooden facades. The product penetrates deeply into the core of the wood without corroding its structure and without destroying the density of the material. Osmo paints are made from natural oils (linseed and sunflower) and natural waxes. Ease of use is characterized by the need for just one layer.
For surfaces that have not yet been painted, you do not need to use a primer if you use Osmo paint. She is known all over the world and has received numerous positive reviews.
