We purchased this because the local store was out of the mix we’d used on most of our tile flooring install. It was a non sanded grout and I wasn’t familiar with it. It set up quicker and was harder to clean than the other product. For an experienced user it’s probably fine.

Worth the extra money!
First time using Prism and it was fantastic. Mixed easy and love how it comes in 2 bags so you know you’re mixing exactly half. I’ve had color consistency with every colored grout until using Prism. Like others say it does dry quickly so don’t mix up more than one bag and don’t get too far ahead of yourself before you wipe it off.

Works well but isn't as dark as shown.
Work well but is lighter than the color shown. I was really looking for a darker color. I really wish it had been the same color as on the box.

Great Grout
We used Arctic White to blend with our bright white tiles. Just what we needed. We didn't use as much as anticipated. The nubs on the tiles provided for a small grout line. We mixed up 1/4 of one bag at a time (2 bags are included in each box). The job went well by following the instructions on the box.

Outdoor grout mix
First time to use this brand of grout, but if I do more outdoor tile, this will definitely be the product I use! EZ mix, superb consistency!

Charcoal color is beautiful
The charcoal grout is a beautiful dark color almost black. But it must be sealed! We wiped and wiped and it comes off on a rag. Sealing it did the trick! Do not use vinegar and water to clean the tile and grout because it will turn light gray!

Prism Grout
Like other reviewers have stated, the color dries lighter than comparison samples.
It filled sm (1/16") and lg gaps (1/4") nicely and the color, tho lighter, is consistent thru out.
When dry, the hardness, seems good. Time will tell for durability.

Exactly what we needed!
Installer specifically requested his preference for this cement grout. The charcoal color gives a natural shadow appearance between tiled "wood planks". The tile is Ardennes Cafe.
