Of course, if you have ugly grout MARBLELIFE can help. Check out of MARBLELIFE MAXOUT Grout Cleaner, or contact your local MARBLELIFE office. Things to Keep in Mind: If you have epoxy grout, you will not need to apply a sealer, as epoxy grouts are non-porous. While this does not mean they cannot be stained, or discolored, it does mean that a sealer is not required. Similarly if you have an acrylic-modified grout here again an additive has been added to make the grout non-porous obviating the need for a sealer. Both of these are rare cases, with most floors being installed with either a sanded or non-sanded cementitious grout which will indeed require a grout sealer. Other notes: If your grout is stained and you are stuggling to clean it. Give MARBLELIFE a call. More than likely the original seal has failed, dirt has penetrated below the surface of the grout where it is easier to clean, and you may need a professional assessment and service to restore the clean look you want before sealing it in.
