GRANITOP is a solvent-based product by appearance liquid and black, specifically developed to treat cracks and, in general imperfections of black polished marble and granite to which it ensures homogeneity. It deeply penetrates the surface, while its wax/silicon nature makes easy both removal of the excess and polishing phase. The treated surface will become lightly tone-enhanced, polished and protected. Granitop does not turn into yellow and allows a very good permeability to water vapour.
