It stabilizes and reduces the absorbency of surfaces resulting in the unbreakable adherence of all plasters in paste form. Ready to use on any porous surface, such as concrete and top coat plaster, gypsum board and cement board. Designed to work with silicone and acrylic plasters, such as HYDROSTOP SILICONE PLASTER and HYDROSTOP ACRYLIC PLASTER of DUROSTICK.
