Drywall and how to prime it before tiles: how to do it correctly

During finishing work, the question often arises: how to prime drywall. For this, acrylic compounds are most often used. They are affordable, completely safe for health and allow for treatment in any room. Why this is needed and how to apply the primer correctly is described below.

Why prime drywall?

Preliminary preparation of drywall before tiling is mandatory work, which 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;
• adhesion properties are improved, i.e. adhesion to the material increases;
• if the primer contains antibacterial additives, the material will not rot.

There is no doubt about whether or not you need to prime your drywall 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 high humidity levels and under conditions of temperature changes.

Types of primer

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

• high penetrating ability;
• quick drying;
• absence of toxic substances;
• improved grip on the surface.

If the question of whether the GVP needs to be primed has been resolved, we can begin to consider the types of primers. Depending on the composition, the following types are distinguished:

1. Acrylic is a universal option that is suitable for almost any surface.
2. Perchlorovinyl is another universal composition, but it is only suitable for outdoor use.
3. Terephthalic the most effective, but it is also used only outside the room.
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 figure out whether it is necessary to apply a primer under the tiles, the answer will be positive. Moreover, for such work it is better to choose an acrylic composition, which is optimally suited for drywall and is also affordable.

How to prime walls

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

• roller - for basic processing (a sprayer can be used instead);
• brush – for hard-to-reach places;
• stationery knife;
• bath.

It’s clear why you need to prime drywall. This is necessary to prepare the surface and increase the service life of materials. The work should be approached responsibly enough to treat the entire area. You need to do this:

1. Use a utility knife to trim the edges of the material that was previously cut. Fragments whose edges have been preserved after 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 begin processing.First, only the seams and screws need to be treated - the entire surface should not be covered at once.
4. Next, use a roller to cover the entire surface of the wall. You need to wait until it dries, which takes up to 8 hours. After that, you can cover it with a second layer. This is especially important for rooms with high humidity.

Thus, there is no doubt whether the GVP needs to be primed or not. This is a useful procedure that ensures the strength and durability of the material, good adhesion and resistance to rotting. Even if you have minimal skills, you can carry out the processing yourself.
