Grout sealing is a crucial step. In fact, we think it is just as important as cleaning your tile floor. High quality protective sealants prevent dirt from re-entering into the porous grout. The grout sealant fills-in and creates a barrier that will protect your tile and grout cleaning much longer. There are 2 options to choose: Clear sealant or Color sealant, Clear sealant is transparent and will protect both the tile and grout. The color sealant is an epoxy stain sealant with a variety of color options, only applied on the grout lines.
