Promat® READY-MIXED FILLER is a creamy putty/filler based on a mix of clay and an inorganic binder. It is especially developed for filling and levelling out construction boards for mantelpieces. Due to its consistency, Promat® READY-MIXED FILLER can be easily caulked or troweled, depending on the application. When used for filling gaps and joints, we recommend dispensing Promat® READY-MIXED FILLER by caulking, as this guarantees easy and optimal distribution and penetration.
