For the transformation of wooden surfaces, various paints are used. Means differ in composition, properties and application features. Polyurethane paint for wood has increased strength and wear resistance. It provides surface protection from various influences. The composition tolerates temperatures from -40 to +150 degrees. About the features of the paint described in the article.
The properties
With polyurethane paint for wood, a resistant film is created that is resistant to moisture, temperature, acids, organic oils. The tool creates increased protection for the coating, so it is often used for exterior decoration.
The coloring composition is appreciated because of:
- high wear resistance;
- the possibility of applying to different surfaces;
- resistance to alkalis, acids, fuel, water, engine oil;
- increased strength of the created coating;
- lack of components that could be dangerous to humans.
Means are resistant to aggressive components, so they are often used in the chemical industry, where standard coatings quickly become unusable. According to reviews, such paints have a long service life.
Where is it used?
Staining with such paint can be performed in:
- hangars and warehouses;
- agricultural facilities;
- public places of premises;
- production shops;
- service stations;
- car washes.
The tool is used for floors in industries where work occurs, which is associated with the heating of various materials. The surface will have a long service life.
According to reviews, such paints are used for painting floors, doors, windows. After the procedure, any surface will retain its operational properties for a long time.
Structure
The properties of the product depend on the components present in the composition. According to the named criterion, paints are one- and two-component. The first type does not need mixing, so it can be applied immediately, without preparation.
Two-component polyurethane wood paints require mixing. They are produced in 2 separate containers: in 1, resin is present, and in the other hardener. One-component polyurethane paints for wood are made of polyurethane. The solvent is toluene or xylene.
Advantages and disadvantages
Their advantages of polyurethane paint for wood distinguish:
- protection of the coating from aggressive fumes, mechanical factors;
- elasticity: after painting, the surface undergoes deformation, but the integrity of the coating is not violated;
- lack of harmful components: polyurethane does not have a negative impact on humans, only the solvent has danger, but after drying it evaporates;
- the ability to update different surfaces - durable, loose, porous;
- ease of application;
- high drying rate;
- long preservation of the result.
According to reviews, it is thanks to the listed properties that the paint is in demand. Of the minuses, a high price and a not very rich selection of products are distinguished. The disadvantages include the toxicity of the solvents present in some agents.
Kinds
Paint on a polyurethane base for wood is of the following types:
- With organic solvents. Such a composition must be diluted with special numbered solvents. Coating strength is achieved after 48 hours. Compositions based on organic solvents are waterproof and protect against the negative effects of external factors.
- Water dispersible. In them, the solvent is replaced with water, so these paints do not emit toxic components. The product creates a thin, durable film that has a decorative and protective effect. The downside is freezing at low temperatures, which is associated with the presence of water in the composition.
- Alkyd-urethane. The compositions of this type have alkyd-urethane varnish, which serves as the basis for a durable film, additives to accelerate drying, pigments and thinners. The tool can be used for outdoor and indoor use.
According to the method of applying the material, there are aerosol and liquid paints applied with a roller or brush.
Application Rules
Wear-resistant polyurethane paint for wood floors is applied as follows:
- First eliminate the old coating. This work is done with sandpaper or a grinder.
- It is necessary to clean the surface of dust.
- If there are cracks and crevices on the surface, they are puttied.
- Apply 1 coat of paint with a roller or a flat brush with natural bristles. One-component paints do not require a primer.
- The treated surface should dry. This is done in 8 hours.
- When painting, 2 finish layers are applied.
So not only polyurethane paint for wood floors is used, but also compositions for other surfaces from this material. Compliance with the sequence of work extends the life of the coating.
Palette
The classic option is black and white polyurethane paint for wood. It is great for updating various surfaces. The main thing is that the selected colors harmonize perfectly in the interior.
Bright colors are relevant:
- red;
- blue;
- green;
- brown;
- Orange;
- yellow;
- pink.
The gray color remains in demand, which, although it looks ordinary, is still attractive. Polyurethane paints of any tones will look beautiful if applied correctly.
The choice
When choosing a coloring composition, it is taken into account:
- humidity;
- terms of operation;
- level of mechanical impact;
- wood species;
- compatibility of paint with previous types of materials.
To paint a tree you need a brush. Polyurethane paints are noticeably better than other coloring compounds. Excellent surface appearance, durability are the main advantages of this composition.
Rating
The best are the following paints:
- Sikkens Redox. This is the leader among the products described. These paints have a rich color palette. They are intended not only for painting wood, but also for updating aluminum and steel. The paint can be used in industrial and marine conditions, it has high resistance to weathering and does not turn yellow. Products are produced in containers of 1.1 and 3.79 liters. The price of paint is determined not only by the volume of the tank, but also by color. For example, a white color of 3.79 liters costs 8500 rubles. 12.8 thousand rubles will have to be paid for green, and 10.1 thousand rubles for blue.
- Milesi. Paints from this manufacturer provide a high-quality result. The volume is 25 liters. The price of 1 liter starts from 500 rubles.
- "Elacor". This paint is also in demand due to the high quality and variety of colors. The price for 1 liter is from 600 rubles.
Polyurethane paints are special compounds that have increased strength. They also serve as protection against external factors. Such paints are applied to different types of wood. For proper coverage, it is necessary to follow the temperature regime and maintain the desired humidity.
