MARBLELIFE Grout Sealer is easy to use and provides lasting resistance to staining from oil, water and food without altering the color, texture and breathability of your stone. You can't keep a floor clean without sealing your grout. Once soiled the struggle to clean your grout begins. Likened to trying to clean-out a test tube with a sponge it becomes difficult to get in and get the dirt out. Better to seal it from ever happening... Of course, if you have ugly grout MARBLELIFE can help. Check out of MARBLELIFE MAXOUT Grout Cleaner, or contact your local MARBLELIFE office.
