A fast-setting, lightweight, polymer-modified, cement-based grout that offers consistent color without mottling or shading, regardless of tile type, temperature or humidity. Creates dense joints that provide more stain resistance than standard cement grouts. Cures quickly and develops high early-strength to accommodate grout joints from 1/16 in. to 1/2 in. Prism may be used for interior or exterior installations, including floors, countertops, walls, ceilings, showers, fountains and pools.

California residents: see   Proposition 65 information

Does the color darken once mixed?

I just received a box of Prism grout in the color 542 Graystone (marked on box and bag) and it looks lighter than I expected and is lighter than sample color on the box and website.

Can this be applied over old grout to fill cracks, chips and gaps?

The old grout job cleared too much grout between the tiles and it should really be refilled or be topped off with new grout. I would never bother to chip out the old grout, but I would consider going to the effort of applying fresh grout on top of the old if I have some chance at sucess.
Asked by: emm
Approximately 2/3 the depth of the grout joint would have to be removed prior to applying new grout. For further assistance please contact our installation division at 800.272.8786 option 2

Will this scratch tile? Is the finished look like other non-sanded cement grouts or like an epoxy?

I can't really tell if this is safe for shiny or glass tiles. In "specifications" it says "No" next to "Sanded," but I don't see anything in the description about whether it's safe for tile surfaces that may scratch if sanded grout is used. I read on another website that Prism grout contains glass instead of sand. That doesn't sound good. Bits of glass rubbing around on the tile sounds like it would scratch. Also, how is the texture when dry? We don't want the rubbery look of epoxy grout as this is a vintage style remodel. I'm using on vintage style tiles with narrow joints; some are matte, some are satin, some are gloss, and don't want scratches or the rubbery epoxy look.
Asked by: SRS
Prism Grout does contain a light aggregate which could possibly scratch soft natural stone and glass tile. We recommend doing a mock-up or to use our Polyblend Non-Sanded Grout for best results. For further assistance please contact our installation division at 800.272.8786 option 2

As with most grouts - it dries lighter than the color swatch but at least the color was uniform over a very large tiling project. The cheaper box store grouts can be really bad for varying shades even from the same mix (usually down to effervescence, which can be impossible to control with some cheap grouts even when instructions are followed to the letter). After bad experiences with those I was very happy to have this simply...work. Now let's hope the caulking on order actually matches the grout for shade and isn't darker...

We had a professional do the job. He even took out part of the first batch and added less water and it still looks to light. Now we are having to pay to have the grout stained. It was uniform but there is a big difference in Tobacco brown and off white.

BUY SOME AND MIX FOR COLOR MATCH. I have a house full of prutid gray which was supposed to be (Saddle Brown). I have 1000 squre feet of 18" tile that I am going to re-grout after Christmas. I recommend you find another product!

Tile is Allen Roth in oyster. It came well packaged but took a looong time to arrive. Also quite pricey (cheaper though than at my local tile store).

Rated 5 out of 5 by from Great cement grout! A quality product from custom. Dont let it dry out too much before working with a sponge. Takes a little more finess & effort to make nice joints compared to a standard cement grout. However, the results are worth it. Color is very true & consistent. Keep all tools clean as you go, & make small batches. Easier to work with in cooler weather.
