FB50 is a polyurethane-based mortar, designed for making expansion joints in ceramic tile and resin floors exposed to thermal and chemical influences. The function of this joint is to absorb the expansion that can occur in industrial floors. These expansions can be due to thermal effects, humidity or structural movements.
The FB50 has been specially formulated to absorb these expansions while maintaining sufficient rigidity to prevent crushing and deterioration of the tile around the joint.
