Ceresit CN 94 is used for brazing substrates inside and outside buildings before using floor leveling mortars, adhesive mortars for ceramic and stone tiles, and flexible waterproofing coatings. It can be used on horizontal and vertical surfaces, on absorbent and non-absorbent surfaces. It is particularly recommended for priming critical substrates, such as screeds with remnants of difficult to remove glue, glazed ceramic tiles, dispersion and epoxy coatings (only inside buildings). The product strengthens the surface and limits the flow of moisture. It can also be applied on anhydrite screeds, cement screeds, asphalt screeds, prefabricated screed elements, e.g. gypsum fiber floor boards, concrete, also compacted by plaster, painted and unpainted wood-based substrates (chipboards, OSB, boards), flooring leveling mortars, existing ceramic and stone tiles, paint coatings (also epoxy), cement, cement-lime and lime plasters, gypsum and cellular concrete substrates. It can also be used on heated floor constructions.
