No-sheen, penetrating sealer formulated to darken, enrich and highlight the character and beauty of unsealed, low-porosity natural stone. It rejuvenates the color and improves the appearance of worn and weathered dense stone. May also be used as a pre-grouting sealer over clean stone surfaces a minimum of 2 hours prior to grouting. Allows moisture-vapor transmission. It also effectively darkens the color of grout joints.
Recommended for use low-porosity natural stone such as marble and granite, dense slate, dense limestone and dense flagstone.
