It stabilizes and reduces the absorbency of surfaces resulting in the unbreakable adherence of all silicone based plasters in paste form. Ready to use on any porous surface, such as concrete and top coat plaster, drywall and cement board. Designed to work with silicone plasters, such as HYDROSTOP SILICONE PLASTER of DUROSTICK.
1lt/8-10m² per coat, depending on the absorbency of the substrate.
