Knauf

The Knauf Flächendicht is a highly flexible liquid seal especially for indoor use. It is ideal as a seal under tiles and plates for damp and wet rooms. Due to the high water barrier capacity, the surface seal prevents the penetration of water into the ground. In addition, it is resistant to aging and alkalis and, thanks to its high elasticity, also offers optimum protection for subse- quent subsurface cracks of up to 2 mm. This makes it suitable for use on underfloor heating systems.
