Stone Impregnator 407 by Harvard

Water-Based Porous Stone and Grout Sealer

Stone Impregnator 407 is a water-based, fluoro-chemical treatment that penetrates into porous stone floors preventing oil and water-based soils from penetrating the stone. By keeping the stain and soil on the floors surface, this product protects the floor and makes it easier to clean. This product will not alter the stone's natural appearance and does not require special maintenance.
