The most important stage of repair in any room is the priming of the surface of the walls. The priming of the walls is carried out regardless of further work: painting the walls, plastering or puttying them, sticking wallpaper, tiling. The main task of the primer layer is to create a reliable adhesion of the surface to the next layer, improving the quality and durability of the decorative coating.
The primer itself is a liquid that impregnates the surface, penetrates into the pores, sticks together dust and peeling. When priming walls, a strong surface is formed with improved adhesion and uniformity, the primer hides spots on the wall, reduces the consumption and smell of the next layer, when painting, it allows you to apply light paints on dark surfaces. There are also special primers that protect the surface from moisture, mold, corrosion, and reveal the texture of wooden coatings.
Variety of primer
High-quality primers are prepared on the basis of safe natural and synthetic film-forming substances, so they can be used both indoors and outdoors. There are several types of soils:
• universal primer;
• deep penetration primer and others.
To determine the choice of soils suitable for a particular type of work, consult with professionals.
So, for example, before gluing wallpaper, it is recommended to use universal soil, which helps to remove dust from the walls and reduces the consumption of wallpaper glue, while it allows the surface to “breathe”.
When preparing the walls before plastering and puttying, it is better to use a deep penetration primer, preferably on an acrylic basis, as it helps to consolidate the base.
Application of the primer
The application of the primer can be entrusted to professionals, but also performed by ourselves. From the instruments you will need a cuvette, a gorsky roller, brush or spray. When applying, guide to ensure that the soil is evenly distributed over the surface, on average per square meter will require about 100-150 milliliters.
The soil must be applied in two layers, withstanding the interval in 30-40 minutes. Paint, plaster and other coatings should be applied after the soil dries completely, more often it is 10-12 hours. It is necessary to prime the surface at a temperature of 5-25 degrees Celsius and air humidity of not more than eighty percent. After surface treatment, the tools are washed with running water.
