StainBlocker for Cement-Based Grout


What’s it for

StainBlocker for Grout is a sealing and performance-enhancing additive to be used when mixing cementitious 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 cleanup easier after the grout is dry. StainBlocker for Grout will not affect grout colour.
