Drywall and how to prime it before tile: how to do it right - Setafi

During finishing work, the question often arises: how to prime drywall. For this, acrylic compositions are most often used. They are affordable, completely safe for health and allow processing in any premises. About why this is necessary, and how to properly apply a primer, is described below.

Why prime drywall

Preliminary preparation of drywall before tiles is a mandatory work that allows you to solve several problems at once:

• the ability to absorb moisture is reduced, which ensures a long service life;
• if you figure out how to properly prime drywall, the surface of the material becomes much stronger;
• adhesive properties are improved, i.e. increased adhesion to the material;
• if the primer contains antibacterial additives, the material will not rot.

There is no question whether drywall should be primed before tiling. Such compositions are inexpensive, and the processing process itself is simple. Moreover, thanks to priming, the material will last much longer even in a room with a high level of humidity and in conditions of temperature changes.

Primer types

To figure out how to properly prime drywall, you first need to choose the composition itself. It must meet several requirements:

• high penetrating power;
• fast drying;
• absence of toxic substances;
• improved adhesion to the surface.

If the question of whether it is necessary to prime the GWP is resolved, you can begin to consider the types of primers. Depending on the composition, the following types are distinguished:

1. Acrylic is a versatile option that is suitable for almost any surface.
2. Perchlorovinyl is another versatile compound, but it is only suitable for outdoor use.
3. Terephthalic the most effective, but it is also used only outside the premises.
4. Alkyd is used on wood; it is not recommended for drywall.
5. Phenolic is also not suitable for these purposes - it is used only for surfaces made of metal and wood.

If you understand whether it is necessary to make a primer under the tile, the answer will be positive. Moreover, for such work it is better to choose an acrylic composition that is optimally suited for drywall and is also affordable.

How to prime walls

It remains to figure out how to prime drywall, you can do it yourself, you need to take the following tools:

• roller - for the main processing (a spray can be used instead);
• brush - for hard-to-reach places;
• stationery knife;
• bath.

It is clear why primed drywall. This is necessary for surface preparation, increasing the service life of materials. The work should be approached responsibly enough to process the entire area. You need to act like this:

1. Cut with a clerical knife the edges of the material that was previously cut. Fragments, the edges of which were preserved after the purchase (remained unchanged), do not need to be cut.
2. Do the same on the other side - it should turn out like this.
3. Dilute the solution and proceed to processing. First, it is necessary to process only the seams and screws - the entire surface should not be covered at once.
4. Next, the entire surface of the wall is covered with a roller. It is necessary to wait until it dries, which takes up to 8 hours. After that, you can cover with a second layer. This is especially important for rooms with high humidity.

Thus, there is no doubt whether the GWP should be primed or not. This is a useful procedure that ensures the strength and durability of the material, good adhesion and resistance to decay. Even with minimal skills, you can do the processing yourself.
