SharpSTONE 925 is a cementitious polyurethane and aggregate mortar designed for the realization of rounded skirting boards, for vertical applications (e.g.: low walls), for concrete repairs or for level adjustments and floor slope corrections. It is composed of a mixture of polyurethane resin, cement and fine aggregates to provide a smooth finish. It is generally applied at a thickness of 3 to mm 6(1/8 to 1/4 in).
