StainBlocker for Grout is a sealing and performance enhancing additive to be used when mixing grout and water. Unlike traditional sealers which are applied to grout after it has dried for 2 - 3 days, StainBlocker for Grout is added directly to the grout mix during installation, to immediately repel dirt and make clean-up easier after the grout is dry. StainBlocker for Grout will not affect grout color.

  • Use with 7 and 10 lb. polyblend grout
  • Add when mixing grout and water
  • Immediately resists dirt, oil, and stains
  • Low odor, low VOC, pH neutral

Rated 2.9 out of 5 by 7 reviewers.
Rated 1 out of 5 by Don't buy The sealer discolred my grout and made it very hard to apply. It's not worth the frsustration just grout and add a topical sealer afterwards. October 21, 2014
Rated 5 out of 5 by Great product This worked great with our grout for the shower. Sealed and done. Waterproof October 21, 2014
Rated 5 out of 5 by Don't know yet I don't know how well it's going to work yet but I felt it was worth the extra investment to protect the grout from staining in the long run. October 14, 2014
Rated 5 out of 5 by Grout Additive I rated this stuff highly, but have not really completed the project yet. This product is supposed to help grout last longer and work as a sealant. It is simple to use, just add it to the mix instead of, or with, water. The grout cured fine. Time will tell as to whether I will use it again. If it does work, it will prove to be a simple solution to sealing grout. September 16, 2014
Rated 2 out of 5 by I've used simalar products that worked better. I've used other products that seemed to give a better finish and hold up better. At this point it is too early to judge the overall. Probably wouldn't get this product again. May 28, 2014
