Water-soluble, silicone-based, acrylic primer, suitable for silicone-based and acrylic plasters. 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, drywall and cement board. Designed to work with silicone and acrylic plasters, such as HYDROSTOP SILICONE PLASTER and HYDROSTOP ACRYLIC PLASTER of DUROSTICK.
Approximately 8-10m²/lt, per coat, depending on the absorbency of the substrate
