BEZILLO EDGE & BOTTOM PROTECTOR is a water based protective impregnation for application to the back/fixing side for all polished, honed marbles, granites and natural stone tiles to avoid humidity/moisture based problems such as: shadows, marks or oxidation appearing on the surface of marble, granite and natural stone surfaces after these have been fixed. The easy application of the product creates an excellent bonding surface which facilitates the adhesion to the sand/cement bedding while reducing the water ingress through the back side of the tile.
