Primer
for the best renovation results

Function of primer

The basic function of primer is to protect the floor. It acts as a protective film and forms the basis for further coating. A primer can:

• reduce absorbency
• consolidate the substrate
• act as a barrier
• glue substrate to covering

Reducing absorbency is one of the main tasks of priming, because when painting or plastering, difficulties can arise due to water loss. Coatings require certain amounts of water and setting time.

By binding particles, primer ensures proper adhesion of the floor and consolidates the porous substrate.

Adhesion of the floor is achieved by means of adhesion primer. Smooth floors in particular need a primer before they are plastered.

Types of primer

The main types of primer include:

• adhesion primer
• barrier primer
• deep primer
• plaster primer

Adhesive primer is specially designed for smooth and less absorbent floors. It has additional plastic particles and prevents the floor from swelling with its protective layer.

Barrier primer prevents stains and discolouration from bleeding through to the coating. It has a high water absorption capacity and promotes vapour diffusion.

Deep primer is a colourless primer for almost all interior mineral substrates. It is mostly used in drywall construction. The primer reduces absorbency and evens out differences.

Plaster primer works similarly to barrier primer and is ideal for decorative plasters.
