Review: Almost didn't buy becasue of negative reviews - I was apprehensive to order this due to a couple of negative write ups but went ahead and got it to test out. It comes out of the tube lighter than the grout color it supposed to match but once it dried it was nearly perfect. I found it easy to use and I've done plenty of caulking in my time. Not sure what the issues were for the people who had negative experiences but I'm happy with the results I got.
Review: Nice Color! - Matched the grout color pretty well. Maybe dries slightly more white, but that could be due to the grout having the sand in it. In the photo, the grout is surrounding the tiles and the caulking is on the bottom sealing the countertop. Really easy to apply once you get going and fast setting. One tube goes a long way!

### ⭐ Not as advertised
*by L***. on June 27, 2022*

I purchased the Mapei Keracaulk U Unsanded Caulk in the color "Rain". The color is actually almost pure white, even after it has cured. I had just installed a tile backsplash using Mapei grout in the exact same color, "Rain", and I expected it to at least kind of match. Both colors are called "Rain" and both are made by the same company, Mapei, but they are nowhere near the same color. I'm very disappointed that Mapei's caulk has ruined my newly installed custom backsplash.
