Specialists about the primer of drywall, opinion is one thing: it is necessary to primitive. And how to primitive, learn from this article.

Why primer plasterboard

Professionals will never paint drywall, glue on it wallpaper or tile, not pre-tugged. For them, the question is: "Does plasterboard grind?" does not exist. And that's why:

• an ordinary plasterboard actively absorbs moisture;
• if you immediately apply paint, it is absorbed unevenly, stains are formed;
• wallpapers, glued to non-primed drywall, will remove only with the layer of cardboard. The same happens with tiles;
• the finishing of the primed drywall is less finishing materials and shears longer;
• on the coated walls, a fungus or mold will not begin.

How and what to primer plasterboard

For drywall, any primer will not fit. It is presented to certain requirements:

• the main thing is the absence in its composition of the solvent;
• the surface formed after applying the primer should be perfect for subsequent processing. From the fact that plasterboard primed, it depends on how strong the adhesion and glue or plastering will be;
• provide protection against moisture.

For the first time, the plasterboard wall is covered with a primer before putting down seams. Not the whole wall, of course, but only seam.

• tool: Someone loves to work with a roller, and someone with a brush, so you get what it is more suitable for us;
• dishes where we will pour the primer. A plastic paint container is perfect. He has a surface corrugated and there is a deepening.

Prepare everything you need, proceed:

• grinding with water. Proportions manufacturers usually indicate;
• pour the solution into the dishes;
• dip the working tool into the solution and apply a thin neat layer. It will be the first layer;
• we wait until the surface is dry and applied the second layer;
• after drying the second layer, you can put it. The total thickness of the primer layers is approximately 0.03 mm, while: more - good, and less not recommended.
