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

Rated 3.1 out of 5 by 20 reviewers.
Rated 1 out of 5 by Unbelievable grout haze I recently tiled two bathrooms and my kitchen with the same tile and grout. Only difference between the bathrooms and the kitchen was the additive sealer. I used the Mapei sealer in the bathrooms and had zero issues. Tile looks amazing. The kitchen, however, was a disaster. The brown grout dried white and I applied it correctly, cleaning up the grout as I went along. I had to scrub the entire floor with sulfamic acid on my hands and knees to get it up and it's still somewhat visible. This sealer added another day's work which wasn't good on a body that had been tiling 300 sq ft in the days before. December 22, 2014
Rated 5 out of 5 by follow directions!!!!!! real the label!!!! if you read the directions and use this product appropriately you should have no problems. this is a grout additive, not a sealer for tile. it is supposed to be mixed in when you are mixing grout. it is a substitution for part of the water that is used to make the grout. again, you do not use this to seal tile. this is a grout additive to seal grout and block stains not seal tile.

Rated 1 out of 5 by Does not work This was recommended by the Home Depot sales person. My husband used it according to the directions and it does not work. Tile was very hard to clean when installing and now we know it doesn't even work. We will have to reseal the tile with another product = more cost, time and aggravation. November 2, 2014
Rated 4 out of 5 by Easy to use I've used this product twice-in a bathroom and on a lanai. In the bathroom around the toilet I noticed some discoloration after a year, and no amount of scrubbing would clean it. I assume the ammonia in urine, due to clumsy men, led to the degradaton of the product. I bought some specific grout cleaner, applied it twice to restore the color and then resealed it(twice) to prevent a re-ocuurence. The lanai is only six months old and has had glass bottles with wine and cola break on the surface. Cleaned up very nicely and no discoloration May 20, 2014
Rated 5 out of 5 by Seems to be working! My HD kitchen designer recommended adding this stain blocker to my grout as part of the installation of my new tile backsplash. It basically replaces an equal amount of the water that would normally be added when mixing the grout and can be added to both HD's sanded and non-sanded Polyblend grouts. No need to pay extra for the installer to come back to seal the grout after it has cured!! I haven't actually tried throwing a bunch of tomato sauce on it yet, but it does seem to be working very well for preventing stains from minor cooking splatters. I guess time only time will tell for sure!! July 27, 2014
