What Customers Are Saying

Customers overwhelmingly praise this grout refresh product for transforming stained, discolored grout into a like-new finish at a fraction of regrouting costs. Most describe dramatic visual results using simple tools like toothbrushes, though many note the application is tedious and time-consuming, requiring patience and careful technique. A few report issues with peeling or uneven coverage, particularly on textured tiles or if grout wasn't pre-cleaned. Despite the effort involved, the vast majority consider the outcome worthwhile and recommend it as an affordable home improvement solution.

Gorgeous color, easy to use nozzle

A little goes a long way, very easy to paint on with a small brush and wipe excess within a couple minutes. You can use paint remover or similar substance if you can’t scrub the grout off your tiles, it works like a charm. I love the color of Castle Wall on my faux marble ceramic tile. While it seems “green” in pictures it goes on like an ecru/bone color and darkens to a perfect silver.

Terribly disappointed

Bought to change color of backsplash grout. Very difficult on 4" vertical tiles. Took me 5 days to get to "good enough". Resorted to cabinet paint instead, which worked. Don't know how long it will last, but could have saved $20!
