For quick, seamless sealing under tiles and panels in indoor applications, e.g. in bathrooms, showers, living areas. CERAfix 302 is suitable for sealing in the composite for water impact classes WO-I, W1-1 and on wall surfaces of water impact class W2-I according to DIN 18534 Part 3 according to the German Building Trade (ZDB) technical information leaflet “Compound sealing”.
The surface must be solid, load-bearing, clean, dry and free from separating substances. The material is applied with a brush or a roller. Before application, prime the surface with CERAfix 101, art. no. 5875100101. Apply an even layer of CERAfix 302 once the primer has dried. Reinforce the elastic surface seal by applying Würth CERAfix 310, art. no. 5875100310, in the wall/floor joint area. The tiles can be adhered directly to the CERAfix 302 once fully dried.
