Buying Guide

Epoxy Grout

In order to make it waterproof and stain resistant, epoxy resin and filler powder are mixed together to create epoxy grout. It's a great choice for counter tops and fountains because it's so long-lasting. A seal isn't necessary.

Due to the fact that it takes longer to apply and sets faster than other forms of grout, epoxy grout must be applied in phases. It's less forgiving and can bring out flaws more clearly.

Powder Grout

This type of cement-based combination, known as powder grout, is not waterproof. To keep it waterproof, it must be sealed the first time and then resealed on a regular basis.

Acrylic Grout

A professional-grade one-component acrylic grout that comes pre-mixed out of a bucket, acrylic grout is stain-resistant and outperforms sanded grout. A number of the advantages of epoxy grout can be found in the pre-mixed composition (see below). It begins to cure as soon as the bucket is removed, so it's best to work in small sections and clean as you go.

A translucent grout with an iridescent sparkle finish, Flexcolor CQ and Flexcolor 3D are available for use with glass tile. There is an additional cost of $30-40 each backsplash job, but the additional benefits outlined below make the upgrading worthwhile.

Stain, mold, and crack resistance are all excellent features of this product. While maintaining great color consistency, it is ideal for a wide range of applications and tile surfaces. An airtight seal isn't required. Installation time is reduced by approximately 66%.

Only a few things to complain about. Even if it's less stain resistant than epoxy but still more expensive, traditional grout must be cleaned immediately after installation because of its lower stain resistance. Does not work well with pebble installations or grout lines wider than 12 inch broad. Steam rooms and saunas are not suggested.

Unsanded Grout

If you're looking for a cement-based grout, this one is for you! In projects including floor and wall tiling, a grout joint spacing of 1/16th to 1/8th of an inch is recommended.

Urethane Grout

In terms of color accuracy, stain resistance, and fracture resistance, this unique water-based urethane grout is unsurpassed. As a result of its revolutionary formulation, this grout may be installed up to 50% faster than typical grouts and does not require sealing. It has a unique combination of flexibility and hardness that allows it to perform at an unprecedented level and resist cracking.

Reflective Grout 

Incorporates the same urethane grout technology that is utilized in Urethane Grout to provide a really unique solution that enhances any glass or metal tile. Three-dimensional, reflecting and translucent grout can be achieved by using reflective grout.

A urethane-based grout with all the advantages. When compared with epoxy grouts, it's simple to apply, and there's no risk of mixing it incorrectly. The best part is that you don't have to seal this grout!


How Long Does It Take For Mosaic Grout To Dry?

24 hours later, the epoxy grout has hardened. The curing time for other grout types ranges from 24 to 72 hours.

How Much Grout Do You Need For Mosaic Tile?

In order to figure out how much grout you'll need, multiply the mosaic's length by its breadth, and then factor in the tile thickness and any gaps in the tile spacing you might have. Grout should be used for a mosaic of this size that is 18 inches by 18 inches, with gaps of less than 1/4 inch, and tiles that are less than 3/8 inch thick.

Should I use sanded or unsanded grout for marble tile?

Even if the joint width is 1/8 or bigger, unsanded grout is typically the best option for smooth, polished tiles like marble. Traditional sanded grout is typically not used by contractors in these instances; instead, epoxy-based, unfinished grout is most commonly used.

Is sanded or unsanded grout better for shower?

When it comes to vertical tile, such as the walls of a bathroom or shower, either sanded or unsanded grout works just as well. Compared to sanded grout, it adheres better on vertical surfaces because of the reduced slump.


The best grout for mosaics is epoxy grout, even though it's a little more challenging to apply. Applied correctly, grout makes the art in the mosaic stand out.
