Review on Mapei Grout Refresh Colorant And Sealer: Grout Paint And Sealant - 8 Ounce Bottle Building Supplies by Justin Live

I used this for a glass mosaic tile clad shower stall and a larger tile floor. My shower looks like new! If you have small glass tiles, here is the method I used to prepare and apply this product: 1. Steam clean grout or use vinegar and water. It doesn't have to be a thorough cleaning, just removing grease stains. DO NOT USE COMET or anything similar as as you will see in other posts this product is non-stick. For millions of lines of mosaic tile, don't use a cotton swab or even a black beveled craft sponge unless you have very strong sedatives or something readily available for the crushing monotony that ensues. Instead, take one of those big yellow tile sponges and cut it into six pieces. You can apply the product to a sponge or tile and then rub it in. Make a 2" x 2" patch - apply more to stubborn areas. Proceed to the next patch, rub the material into the tile.4. Go back to the first patch and wipe the residue off the tile - wiping the surface lightly with a tissue is very effective. To repeat. - Again, if you're not in the habit of sniffing glue and/or don't like slow boredom, don't use cotton swabs - a toothbrush works really well. Use paper towels or a damp cloth to wipe any residue off the tile after about 20 minutes. Very important: Let this material dry. I mean really dry - it seems to harden over time.
