priming

The application of a primer should precede wallpapering, mudding, painting, panel laying, tiling or flooring. The priming of the working surface is crucial for the proper performance of repair and construction works.

What is priming?

Priming consists in applying a layer of primer with a brush or roller on the working surface. Thanks to priming we are able to strengthen the surface and allow it to bond better with the applied material or agent - paint, putty or floor. There are primers on the market in the form of concentrates for dilution with water or in the form of ready to use land for application. The ground should be adjusted to the type of surface, the specificity of the finishing material, as well as temperature and humidity present inside or outside.

Basic criterion for land reparcelling

We distinguish silicone, graft, deep penetrating and strengthening soils.

Silicone soils

Silicone primers are dedicated for application under silicone paints. They reduce and regulate the absorbency of the primed surface without contributing to the elimination of its vapour permeability.

Grafted land

Grafted soils are able to improve adhesion and adjust surface absorptivity. They are dedicated for priming concrete, cement, limestone and gypsum surfaces. They are ideal for installation of ceramic tiles, putties, water paints, floors, plasters and adhesives.

Deep penetrating soil

Deep penetrating soils are used on non-adhesive substrates. They improve the absorbency of the substrate, but their primary purpose is to penetrate and thus improve the bond between old materials. Deep penetrating soils are used mainly for renovation of old plasters or floors. Such measures should be applied independently of other land adapted to the type of work carried out.

Reinforcement soil

This type of soil is less penetrating. They are used to form a strong and flexible film. They can be used under ceramic tiles, brick substrates, adhesives and gypsum plasters.

Parameters of primers

The huge range of products on the market makes it difficult to choose the optimal land. When choosing a primer, apart from its intended use, two key parameters should be taken into account. These are the efficiency and amount of binding particulate matter.

Productivity

The soil yield is determined in square metres per litre. The larger the product, the more efficient it will be naturally and will allow us to primer a larger surface. The soil efficiency should oscillate within 10 m2/l, but this parameter depends on the characteristics of the substrate (its absorptivity and roughness).

Number of binding particulates

The higher the percentage of binding particulate matter, the better the performance of the product. Typically, "higher-shelf" soils have a 10 to 12% share of binding particulate matter, while cheaper products have a 1 to 2% active substance.
