Before applying CERESIT CM 11 make sure to properly prepare the substrate. The substrate must not be wet and cement and concrete screeds must be fully cured prior to application. Any existing dirt, loose debris and coatings should be removed mechanically. Surface unevenness of up to 5mm can be filled on the previous day using CM 11 tile adhesive.
