Is it necessary to seal new grout in bathroom wall and floor tiles?
Yes, you absolutely want to seal the grout, esp in the bathroom. It will preserve the color and texture. Otherwise, it will get rather dirty. You should prob. reseal every year or so.The only exception to this would be if your contractor used grout w/ grout sealer already in it such as Laticrete’s Spectralock grout.www.westchester.floorcoveringsinternational.
