A pre-mixed grout that never needs sealing, urethane grout is highly flexible and stain-resistant. Bostik TruColor is available in 29 colors, and the sparkly Dimensions grout is available in 15 colors.
Urethane grout costs more than cement-based or epoxy grout, but makes up for it with unmatched color-consistency, flexibility, stain resistance, and ease of installation.
+ Color Consistency: From one bucket to the next, your color will be exactly the same!
+ Unique Options: Dimensions has a line of sparkly and metallic grout called Dimensions that looks beautiful in glass and mosaic installations.
+ Crack-Resistant Flexibility: You can install urethane in grout joints ranging from 1/16" to 1/2" wide. Use urethane in tile installations on boats or motor homes to minimize the chance of cracking.
+ Quick Install: Save for clean up, this is a one step installation process. No need to come back and seal later.
+ Long Life in-Bucket: You can open a bucket, use some grout, re-seal the bucket, and then use your grout again up to two years later!
+ Green Product: If you're building a LEED certified house, this is the grout for you!
- Price: Urethane grout is the most expensive grout (per unit) on the market today.
- Sloppiness: Urethane grout is a little difficult to work with on vertical surfaces. (Pro-tip: leave the bucket open for 10 minutes to allow some urethane to evaporate. This will thicken the grout and make wall installations easier)
- Haze: Approximately one tenth of people installing this grout need the urethane grout haze remover after installation.
Urethane grout has a sandy texture, with tiny color-coated quartz beads suspended in a urethane binder. Be gentle when installing urethane grout with weaker, cheaper glass mosaics and tiles, as it has been known to scratch these glass mosaics. However, we have used urethane grout dozens of times on display boards with glass mosaics, and have not yet had an issue with scratching.
Regular TruColor urethane grout can not be used with stainless steel tiles; it will scratch stainless steel. Dimensions is a softer formula, and can be used with delicate marble tiles, glass, and stainless steel.
Bostik produces caulk that matches all of the TruColor grout colors. Use color-matching caulking in expansion joints, such as:
Some people see haze after using the urethane grout. If you see haze within 72 hours of installation, use Blaze Urethane Grout Haze Cleaner.
To reduce the amount of haze left over after your project, dampen the surface of the tile before installing the grout with water and a little bit of dish soap (1 tsp per gallon of water). Work in small sections no more than 10 square feet: grout the area and then clean up with a sponge and water before moving on to the next section. Change your water every 30-50 square feet to reduce the spread of urethane residue.
Use the official grout calculator to estimate how much grout you'll need! Round up; the grout calculator doesn't account for spills or mistakes, and it's always better to have a too much instead of too little.
