AFM Safecoat Grout Sealer is designed specifically for unsealed tile grout. For previously-sealed grout, conduct several small test patches for absorption and compatibility. Also, keep in mind that grout in a shower gets abused more than grout in general-use areas. The heat and moisture in a shower wear a product down quicker than if used in an area without that (such as a floor). So you may well need to reseal more often than in general-use areas that aren't exposed to the heat and moisture of a shower.
