Promising evaluate: “Holy cow! I by no means thought my stained grout would look so good! These pens are so superb. After a bit of priming, they go endlessly! They cowl very effectively and are tremendous straightforward to make use of and canopy the darkest of stains! I’m shopping for 4 extra to cowl the remainder of the home. The tip doesn’t get into the very finish of a line as a result of border, however I prime it a bit for extra paint and push it in with my finger. Additionally, that is nice for these deep small holes or grooves which might be within the tile that go away filth spots which might be nearly not possible to get out. Simply prime it over the opening and rub it in together with your finger and wipe off the remainder. I’ve very gentle beige tile, and the beige shade pens mix completely. I might NOT suggest white except you’ve very white tile. This beige will mix effectively with white as effectively. Can not beat it for the value and the superb job this pen does. One pen will cowl a couple of 3×20-foot space, no downside.” —NatJH
