Ceresit CR90 Crystallizing waterproofing mortar 25kg

Crystallizable waterproofing mortar for concrete elements and structures

For the waterproofing of mineral non-deformable substrates (concrete, clay brickwork, coatings and floor screeds) against moisture and water penetration. CR 90 creates a sealing coating on the surface of the substrate and additionally creates crystals within its porosity. It gradually fills the capillary passages, ultimately blocking the transfer of water within the concrete, in both directions. Internal and external use. For waterproofing
