Betokontakt is a primer that forms the connection between the substrate and the plaster to be applied. You can use Betokontakt for smooth and weak or non-absorbent surfaces. With Betokontakt you can pre-treat mineral surfaces indoors. This ensures good adhesion of plasters to surfaces, such as concrete, which are not immediately suitable for plastering due to their high density and low absorbency. Betokontakt therefore optimizes adhesion.
