Easy and simple use, fast drying CL 51 provides tiling ready substrate only 4 hours after applying second coating layer.Available pack size: 5 kg and 15 kg
CERESIT CL 51 is applicable to all solid, wearable, stable and clean substrates which are ready for laying ceramics and cleaned from bonding affecting substances (e.g. separating agents, particles, dust, grease or dirt). The upper surface must be sufficiently flat and without cracks.
Apply CERESIT CL 51 undiluted using a brush, roller or trowel. Two coats are necessary to create waterproof layer. The second layer can be applied after 2 hours from the application of the first layer. After approximately 4 hours (depending on the installation conditions) substrate is ready for tiles installation.
After making sure that second layer of CERESIT CL 51 is dried and dependable on the installation conditions, proceed with the tile installation by using flexible tiles adhesives CM 16 or CM 17, CM 12 and CM 2 It is recommended to always secure joints and edges with sealing tape CERESIT CL 152, sealed to the first layer and covered by second layer of CL 51.
