Loved this product. I thought the tile I bought was going to be too dark, but after my contractor used the prism grout, it brightened up quite a bit, making me very satisfied with the project.

The product is impossible to remove once it is applied. The entire floor had to be scrubbed with a grout removal solution 4 times and 25 buckets of clean water on a 120 Sq ft floor. " Great Stuff "

Needs Sealer
This product was recommended for use on kitchen wall for not needing a sealer, being an all in product. The color is great, the product is NOT. The grout is falling out after a few months from install, without even touching it. Was used at base of tile project where it met counter top and it completely fell out in a few weeks. You can touch the grout lines gently and the grout comes off on your finger like fine dust. Having it sealed now to hopefully keep from having to fully re-grout.

        Can fill any hole with this white sludge! Sometimes I come upon a very large gap that needs to be stuffed so bad! This Ultimate Performance stuff will get so so hard just the way my wife likes it! You'll fill so many crevices with this white stuff that you'll be exploding with euphoria!!

        False coverage dimensions
        Dear prism representatives! I recommend you to verify the coverage per pound written in the back of every box, this can create conflict between the homeowner and the contractors. You have to specify if is floors or walls There is no way you can cover 461SF with only 17lb of grout on the floor using tile 12”x24” grout joints 1/8” using your specific measurements of coverage we will fail and cost money to both parties.
