Second time I have used this products on a project - and it doesn't disappoint. Easy to use and great results.

DO NOT BUY THIS! they sell bad product that is all dried up

When my tile guy used the wrong color grout and refused to fix it, I was determined to find something that could work. This was perfect. I tried two different colors to match our wood-look tiles. Goes on pretty easily; I squeezed a small bead along the grout line, then rubbed it in with a toothbrush, but eventually realized a cloth worked fine.Just be warned. This stuff is epoxy and will be nearly impossible to remove if you let it dry too long. So when applying, try to stick to the grout as much as possible without excess on the tiles. I've scrubbed, scraped, tried vinegar, and consulted a professional painter before giving up and covering the worst spots with area rugs.

Excellent coverage - better than I had hoped for. Easy to use and color is great.!

Shake frequently. Unfold a large paper clip, unplug spout frequently(material dries quickly in spout). Best to apply thin coat, reapply when dry. My container had a leak at base of spout, perhaps just a problem for me.

I love this product I had always regretted putting white grout in between my subway tile on my backsplash in my kitchen. This made all the difference it even covered over the yellow and grout above my stove that had discolored due to the heat of cooking. I would recommend cleaning up as you go and putting as little on the tile as possible . As soon as it dries it is difficult to clean up. I use small skinny cleaning brushes that I had purchased on Amazon to apply this and the toothbrush and then a soft cloth to wash it off.

Very happy! Color is great! Easy to apply! Thank you!
