Facade paint for outdoor works performs not only a decorative function, providing a more cozy and attractive appearance for a long time, but also protects the walls and roof surfaces from the effects of precipitation, sunlight and temperature changes. High-quality paint will provide better protection, a solid, durable coating, will facilitate the process of staining and retain its functions and beautiful appearance for a long time. Today the market offers a huge range of facade paints for outdoor works, made on different bases and intended for different surfaces. In order not to make a mistake when choosing, let's look at the different types of paints and in what surfaces they are intended.
Water-based paints
Facade water-based paints for outdoor works, or rather, two of their varieties - acrylic (latex) and silicone, one of the most popular. These types of facade paints for outdoor use are suitable for use in brick , metal, concrete, plaster and other surfaces.
Modern high-quality water-based paints have such advantages:
- high vapor permeability - paint "breathes", which means it is more durable, not subject to peeling;
- well holds on almost any surface - wood, plaster, stone and brickwork, metal, etc .;
- is resistant to the effects of atmospheric phenomena and sunlight;
- the possibility of toning - you can get any desired shade by adding a white base color;
- short drying time (on average 1-6 hours);
- coating of such paints the most durable - up to 15 years or more;
- resistance to contamination and the ability to self-cleaning;
- does not have a specific odor;
- incombustible;
- environmentally friendly.
Silicone facade paints for outdoor applications are more durable and durable than acrylics, and are suitable for a wider range of surfaces, but are significantly more expensive.
Alkyd Paints
Despite the fact that water-based facade paints have an undoubted advantage for outdoor works, in some cases it is preferable to use alkyd (oil paints).
They adhere well to the surface, are durable, but are more prone to peeling and crumbling over time. Their use is preferable in two cases:
- if you are painting unstable surfaces, prone to chalking and shedding;
- if the surface has already been painted with alkyd paint 3 or more times.
Sometimes it is advised to paint metal surfaces with this type of paints, especially those that can be corroded; as well as wooden - alkyd paints are waterproof and better protect them from defeat by mold and fungus.
Alkyd paint can not be applied directly to fresh brickwork and galvanized iron - it is afraid of alkaline environment and quickly falls off. In addition, it is more difficult to work with, and if necessary not as easy to wash as water-based. The drawbacks of such a paint include a long drying time - sometimes up to 24 hours or more; sharp specific smell and a tendency to burn out.
Facade exterior paints
This type of paints, as a rule, has the same basis as water-emulsion paints, and therefore the same characteristics - a high level of vapor permeability, resistance to atmospheric phenomena and sun rays, environmental safety, etc. But the coating formed by textured paints is more durable and stable. In addition, with their help, it is possible to disguise small surface defects, for example, small cracks. To apply this paint, various devices are used, for example, special textural spatulas, combs, rollers, etc., with which a special, patterned surface structure is created.
