For parquet installation, preferably use the same adhesives used for bonding of parquet underlay. Storage requirements ^ dry ^ 25 m2 roll Available packaging

EXAMINATION OF SUBFLOOR Prior to processing, the subfloor must be checked according to the standard DIN 18356, DIN 18365 or corresponding national standards. The subfloor shall be resistant to pressure and tension, free of cracks, must have sufficient surface strength, be permanently dry, level, clean and free of from contaminants that may prevent adhesion, sinter layers etc. In addition, porosity and grip of surface need to be checked. Also check moisture content and absorption of subfloors as well as temperature, air humidity and subfloor temperature. SUBFLOOR PREPARATION It must be ensured...
