StainBlocker for Grout is a sealing and performance enhancing additive to be used when mixing grout and water. Unlike traditional sealers which are applied to grout after it has dried for 2 - 3 days, StainBlocker for Grout is added directly to the grout mix during installation, to immediately repel dirt and make clean-up easier after the grout is dry. StainBlocker for Grout will not affect grout color.
