Cement-based grout is the most common type of grout and the least expensive, but needs to be sealed after installation to prevent staining.
There are dozens of grout manufacturers, each with their own collections of 30+ colors.
Cementitious grout comes in Sanded and Non-sanded varieties and is a powder mixed with water during installation.
+ Color Selection: Cement-based grouts are the most common type of grout, and as such have the widest color selection.
+ Easy to Install, Easy to Clean Up: After installation, all you need is a wet cloth or, at worst, some light scrubbing to remove grout residue from your tiles.
+ Inexpensive: Per unit, cement-based grout is the cheapest grout on the market.
- Poor Color Consistency: Many factors (including minerals in your water, how you mix the grout, humidity, etc.) can affect the look of your grout, causing inconsistencies and hazy efflorescence.
- Porosity: Of the four major grout types, this is the only one with pores, which can allow staining and bacterial growth.
- Needs to be Sealed: A penetrating sealer is recommended to protect this grout from staining and mildew.
- Brittleness: Caulking is needed for corners and edges. Cementitious grout in corners will crack and flake out over time, and can crumble if not installed properly.
Prism is a superior cementitious grout, with a finer texture than sanded grout and better color consistency.
Prism can be used in grout lines ranging from 1/16" to 1/2". Despite having a slightly sandy texture, Prism can be used with glass and soft marbles, unlike sanded cement grout.
At $39 for a 17 lb unit, it is more expensive than basic cement-based grout, and still requires a sealer.
However, you won't have efflorescence or color splotches with Prism. This is an ideal grout for use with marble, travertine, limestone, and slate. Seal your natural stone before you grout with Prism for easier grout clean up and to prevent the grout from discoloring the stone, then add another coat of sealer to everything (grout and stone) after the Prism grout has cured (3 days).
Instead of mixing water with your cement-based grout, mix in Grout Shield. Grout Shield bonds with the cement in such a way that you'll never have to seal your grout again.
We stock the 70oz bottle to go with our 17lb boxes of Prism. Mix 1 bottle into every one box's worth of grout powder (mixing up half of that 17lbs? only use half of the bottle).
At $39.98 per bottle + $39 per box of Prism, this method is almost the same cost as an $89 bucket of QuartzLock pre-mixed grout, but cement grout has a longer working time and cement grout residue is easier to clean up.

Our acrylic latex caulks are available in the same colors and textures as our grouts, and as such will blend right in!
It's a good idea to use caulk in any place where your tile meets a surface that has some movement (such as a bathtub), or where two different planes meet (such as a countertop and backspash). If you use grout instead of caulking in these areas, over time cracks will appear.
We recommend using the matching silicone caulk for wet areas, such as in a shower or tub. It repels water to an extent that acrylic latex caulk can't, but is harder to apply and clean up (so there's no need to use it in areas that aren't exposed to moisture).

Most natural stone tiles and mosaics are porous. The loose pigments in cement-based grouts are blended into the grout and can sink into these pores and stain the stone. By sealing your stone before grouting, you're protecting the stone from being tinted by the grout pigments. Grouts without pigment-based color (pre-mixed and epoxy) will not stain natural stone.
After the grout is installed, wait 3 days for the grout to cure, then apply sealer to everything. The stone will get a second coat and the grout will be protected from stains.
You can also use Miracle's Grout Pens to quickly and cleanly recolor grout to one of three colors: white, buff, and gray.
