There are many wall priming preparations available on the market. They are most often called: primer, priming emulsion or priming paint. Many people wonder what the differences are between them and which one will be best in a specific case. Read our short article and it will be easier for you to make your choice.

Proper priming of walls is extremely important in the case of unstable, chalky and highly absorbent substrates. The primer penetrates deep into the wall layer and strengthens it thanks to the content of resin substances. The walls become less absorbent, their dustiness decreases and their adhesion improves. The primer is not used for walls in good condition. In such cases, washing and drying the surface is usually enough. The primer, especially the deeply penetrating one, is recommended for older walls with low cohesion. Suitable for cement, gypsum, plasterboard, lime, cement-lime plasters, concrete, aerated concrete, impregnated wood-like substrates and many others. It can be used as a base for paints, plasters, putties, adhesives and floors inside and outside buildings.

Primer paint is a primer whose task is not only to strengthen the wall, but also to cover it with color. The preparation increases the adhesion of the wall, making it easier to apply the right color. No primer emulsion is used as the final wall covering.

What types of primers are there?

There are various types of primers available on the market with different parameters and different purposes. One of the most important parameters is its viscosity, which determines the ability of the paint to stay on a given surface. Other parameters worth paying attention to are density and drying time. There are latex primers (mainly for plaster, cement and cement-lime surfaces), acrylic paints (mainly for cement), bridging paints (for mineral coatings), wall primers, and paints intended for steel.
