The SchimmelX safety primer based on hyrosol acrylate provides effective long-term film protection for surfaces at risk of mold infestation. The film protection prevents infestation and at the same time strengthens porous, sandy or chalky surfaces. The absorbency of these materials is additionally regulated, but without closing or sealing the surfaces. To use, the primer is applied undiluted to the surface, although with highly absorbent materials two passes are required for full effectiveness.
