If you have unsealed Portland cement grout, sanded or unsanded, AFM Grout Sealer will not only seal the surface but will strengthen the grout and make it easier to clean. Simply apply 2 coats of Grout sealer directly to the grout lines, and let cure. Make sure to wipe off any excess that doesn't penetrate into the grout, and clean any overflow of the sealer that may have gotten onto the tiles off right away.
