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.

Pristine
Great DIY product, easy to follow step by step directions and consistent color. For reviews of inconsistent color...it gets darker when wet...just like when your sidewalk gets darker when wet, its not a defect. (see image-right side is wet)

Check the color sample IN STORE
I used this grout for the first time and my color was so off from what the box showed. I reached out to Custom and they advised the color on the box is NOT what you will get when the grout is installed. Check the color sample in the store! Exact Match
