The box suggests it for heavily staining areas. This higher quality grout, though, has added stain repellent ingredients in comparison to lesser products.

Yes it can. I used a glossy glass tile on my backsplash in the kitchen. My tile setter was very happy with the product and it looks great on the wall. I also used it on the floor for porcelain tile. Great product and easy to clean.

I would check with a tile company & ask them if they carry color that could be added to the white. You might call the company number on the box & as for recommendations.

is prism sanded or non sanded

I guess the answer to sanded vs non-sanded is neither. Product contains small glass spheres instead of sand, and was great for bridging the gap from smaller than 1/8" to bigger than 1/8" grout lines

My installer really liked this grout. He said it was fast and easy to use. I like it because it doesn’t require sealing. The color is off but fortunately that worked out okay as the Bone is white. There is no beige in it as pictured on the bag. And the color didn’t deepen over time. As others have observed, you may want to consider going with a darker color than pictured on the bag.

Needed to remodel the small bath in our house (built in 1960) this included the shower and floor. I have used Custom Building Products grout for years but not the Prism line until now. The prism grout worked perfect, easy mixing (no lumps) and was easy to float, it dose set up faster than the regular line of grout, this can be good or bad depending how fast you work. Cleanup is a bit sticky compared to the regular line of grout but is worth it for a better product, time will tell if it lives up to its "stain resistant - no sealer required" statement. The only downside is that they do not recommend using it with glass tile, had to use the regular smooth grout for those tiles, beyond that, great product.

WRONG COLOR IN BOX

The box has two bags and you would assume that they would be the same color as written on the box. NOPE! One bag was "earth" (what I purchased) and the other bag looks like "linen" in the same EARTH box. So now we have half the main room in one color and the other half in a light color. I am so angry I don't even know how to write this review in a calm manner.

love this grout sooo easy to work with
I purchased Prism grout based on the claims of the product and recommendations to use manually mixed grout on my biggest tile project yet, 345 sf of ceramic tile. I had previously used pre-mixed sanded grout on a couple small entryway tile projects and found it dried quickly and was extremely hard to clean off the tiles before it dried. The Prism grout has finer sand, almost mixes itself into lump free state. I mixed half a bag at a time, and it never dried out on me. My grout lines were 3/16, and it laid in them beautifully. I worked the edges of 4-5 12x24” tiles at a time before floating and wiping clean. It did dry a lot lighter than the swatch on the bag but darkened to a satisfactory color after sealing it. It left a haze on the tiles, which I went back over and wiped off once with water the next day, followed by two cleanings with haze remover, and the tiles looked good as new. Sealed the grout lines (had to let the sealer really soak in to darken the grout) and tiles. My customer is very happy. As far as the grout color, I will simply choose a darker color next time. I will definitely use this grout again.
