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, providing a safe, reliable, robust fireplace protection system developed to resist continuous high temperatures of up to 1000°C.
Due to its consistency, PROMAFOUR ®-HT JOINTFILLER can be easily caulked or trowelled, depending on the application.
These are sold as individual ones or sold in a box of 6. Please contact to discuss how much you will need for your project.
