Rated 4 out of 5 by I wish I had known this before I bought this premixed grout for a DIY glass mosaic backsplash project. The container states that this grout is stain resistant (unlike the box of regular powder grout) so I figured this would save me the sealing step. I had used this grout before on floor ceramic tiles with no problems; however, putting this on the wall is a different story. The consistency makes it very hard to spread on a vertical surface, it keeps falling in blobs unless you are very careful (and work slowly). Initially, I started working on 2 x 1 ft segments and by the time I was ready to wipe, the grout had dried considerably making it impossible to wipe. I learned my lesson fast and was able to wipe everything just fine when working in sections not bigger than 1sq ft. To remove the haze from the initial tiles, I waited 2 days (I saw that you needed to wait for it to cure). I first used a razor blade scraper to scrape some of the grout residue from the mosaics, then, I used a 50% vinegar solution to scrub with a scrubbing sponge. This took a lot of time, patience, scrubbing, and worked moderately well. I saw that the tile manufacturer recommends Kaboom foamtastic (available at Target) to remove grout haze, so I tried this and the haze was gone like magic! I still used the scrubbing sponge but I did not have to scrub hard at all. I wish I had known this before spending so much time and elbow grease. September 3, 2014
Rated 5 out of 5 by water based pre-mix saved me so much time ! My project involved altering the grout into many different colors and shades - and this pre-mix was very easy to use. This mural is 2 ' 6 " x 3 ' and will be the central aspect of a 9 x 5 tiled shower room. November 4, 2014
Rated 5 out of 5 by Easy to use, good texture This was easy to use and with being pre-mixed it was ready to use with no mixing...had a great texture, consistency and was easy to spread. October 21, 2014
Rated 1 out of 5 by Not recommended for use with wall tiles This is one of the worse products I have had the misfortune of using. Trying to apply it to tiled walls in a shower has been a nightmare. I also was unable to use a grout float and had to use a small spatula and it still kept falling off the tile so a lot of the grout was wasted. The only positive is the color, we used the Sandstone and it blends beautiful with the tile. I also bought the caulking to match and can only hope it works better. November 16, 2014
Rated 2 out of 5 by Coarse and Gray I bought this grout to replace broken grout in my shower. The container describes the grout as "bright white," but it is really a light gray and the texture is coarse. It doesn't match the original grout. In fact, it looks older and ready to crumble. I bought this grout because it was pre-mixed. The convenience wasn't worth it. Next time I'll try a different product. December 24, 2013
