CT 19 is a special primer and adhesion promoter to ensure reliable and uniform adhesion on problem substrates.


The rough surface produced by the primer ensures a better bonding. CT 19 also reduces the absorbency of the substrate. Well suited to prevent negative reactions between cement-based and gypsum-bound building materials.

Step by step

Substrate preparation

Before applying CT 19, test the load-bearing capacity and strength of the substrate. Clean the surface and remove any dust. CT19 is ready-to-use and can be applied with a brush or roller.
