DIAMOND GROUT DIMENSION 18# by Bostik

This is great grout. I'm not an expert on grout, but using this product for a kitchen backsplash made the really easy for a couple of first time DIY tilers get the job done painlessly.. This grout was suggested by the company we boughtt the tile from as a good color match for our tile and it turned out to be an excellent choice. We were looking for something that would sort of blend into the background and let the tile stand on its own rather than a color that would stand out. It is a light gray and has little flecks of glass in it. It just has a really unique look to it, while sort of receding to the background and letting the tile be the star of the show. It has a good consistency, goes on really smooth and easily. It has a low odor (but is not even as strong as a paint odor). I am very sensititve to chemical fumes and this did not give me a headache after working with it for a few hours. We were also interested in this product because it is a polyurethane based grout so it should not mold or crack (we are using it in a seasonal house). It's very expensive for grout but worth the money IMO.

This stuff is obscenely expensive, hard to apply, and gets mildewy and stained quickly and is nearly impossible to clean. It loses its sparkly quality very quickly and just looks gray. Don't believe the eco-hype, it's trash. Use regular grout and save the money and headache.

After trial and error with other grout, this grout was perfect with our unique aluminum sphere tile. Very easy to apply. Exact look I was going for.

This material is relatively easy to use particularly when trying to grout around a lot of small stones or I assume small tiles, such as one would need to put down on a shower floor as I did. I used it around stones with a somewhat porous surface and if I had used regular grout it would have filled in the small imperfections in the stones which I did not want to do, therefore I give this material high marks for its ability to allow the stones to appear more natural. Also the cleanup was easy compared to the cloudy grout that would have otherwise occurred. On my shower walls I used regular grout on the large tiles but the diamond grout on the floor is a perfect blend. I also give it high marks because the surface it leaves on and between the stones is not slippery when wet therefore it gives a shower floor a good safety grip but not an unpleasant one on your feet. It is rather like a very fine sandpaper. The only reason I gave it one less star is because of the cost.

This grout is beautiful, but it's expensive and harder to work with. I think it's worth it. I've used this type of grout in kitchen and bath.

This is the worst product. My tile installer warned me not to use it and I insisted anyway.H e had a terrible time, installing it. It took 3 times more than the directions said and it stains terrible and the stains do not come out. I'm in the process of replacing it all. It was an expensive mistake.

I bought and installed this product 3 years ago. The first year was nice and the grout performed as promised. By year two the grout was mildewing in some locations, and had fallen out of others. I would clean the area, remove the ugly grout and redo it. Third year come up, and same issue. I spent a lot of money on a product that didn't perform as promised. Not happy, and looking to redo the wall again.

The look is fabulous!!!I am so glad that I spent the extra money on this groute. It has brought the beauty of the mosaic tiles I have chosen
