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 1.0 out of 5.0 by Big Mistake! We are in the process of remodeling bathrooms and kitchen. A HD sales associate recommended this product to help save time. We followed directions on grout (Pollyblend) and the sealer exactly. We had installed wood grain tile. The grout is now imbedded in the wood grain groves of the tile. Now we have to wait 7-10 days for grout to completely cure and then scrub the floor with Sulfanic (sp) acid (as directed by company rep.) So a product that was supposed to help us save time has added a great deal of time, effort and now more $ for the acid too. VERY UNSATISFIED- to say the least. April 24, 2015
Rated 5.0 out of 5.0 by DIYers biggest tile mistake I wouldn't be surprised if the people that had a major problem with grout haze were using it with a natural stone tile, which HAS to be sealed before grouting. Just a couple coats of a topical sealer will prevent a grout haze on natural stone, i.e. Marble, Travertine, Granite, Slate, etc. Stone tile is naturally absorbent and unlike ceramic or porcelain it is not sealed unless you, the installer, seals it. If the stone is not sealed, the grout haze is horrible, and extremely difficult to remove. This stainblocker is an excellent product and prevents the trouble of having to reseal your grout through the years. March 5, 2015
Rated 1.0 out of 5.0 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 5.0 out of 5.0 by Great stuff,try it,it works. My installer ask for this product,I over looked it at the store.I bought another brand,brought it home.Marcus said "that will turn your grout the wrong shade" He wanted this brand to do the job right.He was correct.The job was beautiful.Thanks February 25, 2015
Rated 5.0 out of 5.0 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 5.0 out of 5.0 by Great for outdoor patio I used this product for a tiled 18 x 22 ft outdoor patio and it performs fantastically three years later. I chose a light tan colored porcelain floor tile to repel outdoor heat and a tan grout. Worried that despite being cool, the tiles would end up looking dirty and horrible after a year or two. My tile guy had never used this before but I purchased it and he mixed this in. We used the flexible grout home depot sells cant remember the name to allow for movement in freezing temperatures. He had no problem until the very end of the third day when he rushed to finish cleaning up the grout haze before it rained and did not get up all of the grout haze as he should have. So as might be expected, after that same haze appeared on about a 6 x 9 spot. It looked like grout haze to me. Seen it before and yeah it is hard to clean up no matter what is in the grout. He returned a few days later wiped it down and got it up. Don't know what he used but he didn't seem to have a big problem. At any rate, I would DEFINTELY use this product again with no problem. Some might say that mine was ok because my tiles were light-colored and any haze made no difference. But I was using porcelain which is pretty much impenetrable so I don't think the haze remained on top or seeped in. I should be able to see it and I don't and it has rained and rained over the past few years. So I really like this product. By the way, my tile guy did not seal the grout either. He loved that. If it weren't for the price at the time I would give it five stars . I think it was like $16 for a bottle but I guess it saved me on having to pay him to seal it. I would simply say make sure you get up all the grout. Looks can be deceiving and when grout haze dries yeah that's a problem. April 10, 2013
Rated 4.0 out of 5.0 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 1.0 out of 5.0 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
