It’s crucial to make sure your walls are strong and long-lasting when remodeling a kitchen or bathroom. Because they are constantly exposed to moisture, wet rooms need extra care to avoid problems like mildew, mold, and structural damage. A waterproofing primer is one of the best ways to keep these areas safe.
Your walls’ surface and any potential moisture infiltration are shielded from one another by a waterproofing primer. This crucial layer keeps the underlying structure safe from water damage while also improving the adhesion of your final wall finish. It makes sense to start with a waterproofing primer whether you’re working with paint, tiles, or other materials.
A straightforward but essential step in the preparation process is applying a waterproofing primer. It aids in sealing the wall’s pores and other flaws, ensuring that moisture escapes. This additional layer of protection is especially crucial in spaces where walls are regularly exposed to moisture or water, such as basements, kitchens, and showers.
Your walls can last longer and require fewer expensive repairs if you take the time to apply a waterproofing primer. It’s a simple step that will ensure your wet rooms stay dry, secure, and gorgeous for many years to come.

Procedure for installing a water barrier
Either during the building of a new facility or during significant repairs to an existing one, waterproofing work is completed. That is to say, the old waterproofing will be harmed and the bathroom tiles will be removed if you decide to replace them. Consequently, the coating and screed are entirely removed to the concrete base, and all waterproofing and finishing work is then redone layer by layer.
This is a crucial matter. Such rooms are very likely to leak, so it is imperative to strictly adhere to the instructions for waterproofing the walls and especially the floors. This will protect you from needless repair costs in the event that something goes wrong in your neighbors’ apartment below.
Your "pie" should consist of a minimum of four layers:
- Waterproofing primer;
- A layer of rolled waterproofing;
- Cement screed;
- Tile or other flooring.
In this post, we’ll discuss the first and most crucial layer. About the types of water-repellent primer, their applications, and their requirements.
To prevent moisture damage in wet areas such as laundry rooms, kitchens, and bathrooms, waterproofing primer is a must. In order to stop water from seeping into walls and floors, which can result in mold, mildew, and structural problems, it forms a robust, water-resistant barrier on surfaces. Before tiling or painting, use a waterproofing primer to keep your wet room safe, sturdy, and free of moisture-related issues.
All about waterproofing primer
The substance under description is an opaque, thick liquid that permeates the surface structure and, upon drying, forms a film that repels water.
How it works
Primers are generally designed to give materials their maximum adhesive properties. Stated differently, its purpose is to enhance the bonding of layers to one another, thereby impacting the coating’s longevity and quality. To stop water from seeping into the material, a waterproofing primer for a sauna, bath, or other damp area must also be water-repellent. Seeping through the wood fibers and into the tiniest pores and cracks in concrete, brick, or plasterboard, it fills the spaces before crystallizing to form a moisture-blocking barrier.
In addition, the material that does not absorb and stays on the surface forms a film with strong adhesive qualities, strengthening the monolithic base.
Advice: Take care when selecting a primer for do-it-yourself repairs. Not only must there be deep penetration, but waterproofing as well.
How to choose the right composition
Different bases are used to create primer compositions with waterproofing properties:
There are those among them that are solely adhesive; these are used on strong, waterproof surfaces like plastered or oil-painted surfaces. Others can level the surface and strengthen it in preparation for the next layer to be applied. They are applied prior to the application of tile adhesive, decorative plaster, or other thick coatings and are classified as regular and deep penetration.
- Regular waterproofing primer for the bathroom penetrates into the top layer of the base to a depth of 3 cm;
- Deep penetration primer is capable of gluing a layer up to 10 cm thick.
Kindly take note! You can only use mineral, acrylic, and alkyd compounds for interior work. The remaining ones are used to waterproof external structures and contain hazardous materials.
How to apply primer correctly
You can see that this work is not complicated at all by watching the video that has been posted here. The most important thing is to ensure that no areas remain untreated in order to prevent breaks in the waterproofing film. Mineral primer can be applied with a roller, brush, or sprayer; putty-like spatulas are frequently used for this purpose.
But first, the surface needs to be ready for work.
- Remove debris, sweep and vacuum;
- Seal all large potholes, cracks and seams between slabs with mortar;
- Degrease oil stains;
- If the surface is wet, dry completely.
As the first layer is nearly entirely absorbed into the material, waterproofing primer is typically applied in bathrooms in two or more layers. On the surface that has dried, the second and, if required, the third layer are applied. After priming is finished, finishing work can only be started 10 to 12 hours later because this is how long it takes for the composition’s water-repellent qualities to show.
Kindly take note. The primer can be added to plaster mortar or tile adhesive to improve the effect, but no more than 4 percent should be added.
The following guidelines ought to be followed when using a primer:
- Apply only at an ambient temperature of +5 to +25 degrees;
- If the composition was frozen, it is defrosted under natural conditions, at room temperature, without allowing it to heat up;
- You should always study the instructions on the packaging and strictly follow them. Concentrated formulations should be diluted strictly in the specified proportions and with the recommended solvent;
- When working, it is necessary to use gloves, special clothing and other personal protective equipment.
