Promafour

PROMAFOUR®-HT JOINTFILLER is a creamy putty/filler based on a mix of clay and an inorganic binder. It is especially developed for filling and levelling out PROMAFOUR® construction boards for mantelpieces.

Due to its consistency, PROMAFOUR®-HT JOINTFILLER can be easily caulked or troweled, depending on the application.

When used for filling gaps and joints, we recommend dispensing PROMAFOUR®-HT JOINTFILLER by caulking, as this guarantees easy and optimal distribution and penetration.
