A water-soluble preparation based on polymer resins. It notably strengthens the surface and protects it against excessive moisture. To be used in the Water Block system as a primer for waterproofing systems and tile adhesives. It can be used as a hydrophobing agent as well. After drying, it creates a transparent, colorless coating characterized by high adhesion, notable flexibility, water vapor permeability, and non-flammable nature. For indoor and outdoor use.

  • protects the surface against the harmful effects of moisture

  • evens out uneven absorbency of surfaces and reduces it

  • improves adhesion to the surface

  • strengthens the surface by eliminating dusting and excessive abrasion

  • provides a protective coating for screeds, facilitating their maintenance
