StainBlocker for Grout is a sealing and performance enhancing additive to be used when mixing grout and water.

StainBlocker for Grout will not affect grout color.

  • Add when mixing grout and water
  • Immediately resists dirt, oil and stains

Customer Questions & Answers

Is this made for non sanded or sanded grout?

Asked by: lynniebee
This sealer will work on either. I just re-grouted my bathroom using both sanded and non-sanded grout. On both, I used this stainblocker without any issues whatsoever...Just follow the directions on the bottle and you won't have any issues either.

how long does stainblocker for grout by custom building products last as far a sealer

Asked by: Anonymous
It has a 1 year manufacturer warranty, but I haven't found any actual homeowner info on how long one can expect it to last beyond the warranty period. Undoubtedly, it will depend on whether or not it's used in a stain-prone area (like a tile countertop or floor). I haven't had mine long enough to say for sure, but I can say that it's well worth the minimal extra cost to add this stain blocker to the grout mixture during the initial application.

Stain Blocker Update

You state in your reply that the Stain Blocker is a sealer designed to repeal dirt and make cleaning easier and will not make the grout waterproof or stain proof. Well my question is, why is it called stain blocker and depicted on your container label water beading in the grout lines.
Asked by: Dayton
Unfortunately, the answer given to you is not completely accurate. This product is a stainblocker/sealer. It does make cleanup easer by preventing dirt, etc. from working it's way into the grout. This product also does prevent stains in the same way I just mentioned. As far as water beading up on the tile, this product won't do that completely. It will provide some degree of water repelling qualities, but only on the grout which is where this product is mixed into. The degree of stain and water resistance is in direct relation to the ratio you mix this with the grout. The included directions on the bottle further explain this.

StainBlocker 32 oz. Additive for Grout is rated 3.1 out of 5 by 35.

I have done numerous tile projects over the last 30 years and based on my professional opinion I would not recommended this product. The haze following the install is to excessive. Necessitating copious amounts of water to clean and wipe. Not worth the effort. Tile finish has still not returned. Best to seal the tile afterwards like conventional methods.

Rated 1 out of 5 by from Worthless Product, does nothing it claims. A licensed Contractors opinion Had no problems with mixing, applying or wiping down the product. Really no difference than standard water mix grout. BUT, the product offers NO benefit what so ever. After curing, the grout absorbs water just as if we had used a water only mix. The label is certainly a falsehood, as water does not shed at all, and quickly absorbs into grout. I could immediately see the grout darken when water was sprayed onto tile. We have used "Procolor Stain Guard admix" for years and it actually works as advertised. It does cost twice as much, but at least it performs. Find a local tile dealer and use a product that works.

Rated 5 out of 5 by from easy installation The people with bad reviews of hard to remove grout haze had to have left the excess grout on the surface too long,I tiled an entire shower; walls and floor with ceramic and glass mosaic as well as bathroom floor approx 125 sq. Ft with zero problems outside the usual haze. Mixing this product is also convenient being it's in a 32oz jug you pour it in bucket, the refill with water and dump the powered grout in, no guesswork on how much water or need to bring a measuring cup out to ensure proper mixing. I'd absolutely use this product again; no reason not to. it's like a $19 insurance policy for your expensive tile job.

Rated 5 out of 5 by from 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.

Rated 2 out of 5 by from Read the fine print! NOT A SEALER! Long story short. Purchased this product along with poly blend non sanded grout for tub enclosure. Looks good and yes grout seems strong (but it's new) and pretty. The problem is! This is not a waterproof sealer or actually any kind of sealant. It's a stain blocker ONLY. So if you want sealer look elsewhere. To me this is unnecessary step. You seal the grout to keep out stains and make waterproof. I was under the impression this was a full sealer and blocker. The only reason I see to have this is if you don't seal. But why would you not seal and moisture proof your grout anywhere you use it?!?

Rated 4 out of 5 by from Good product- Used all the time on customer installs I am a professional remodeling contractor who specializes in bathroom installation. I have installed thousands of square feet of tile before and after using this product (once it was introduced to the market). Grout haze is an installer error and not the fault of this product. The grout is definitely stronger and more stain resistant when using this product. I have used it in my own shower and it works great. For people who are getting staining, it could be so many issues. No grout additive can prevent all stains. This product is Not desisgned to repel water. Even a sealer that is applied after grouting will not SEAL tile. If you want the least stains, go with an epoxy grout. This is a great product for the price and DOES work.

Rated 5 out of 5 by from 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 out of 5 by from Best grout sealer I've used!!! I remodeled a bathroom in 2015 and utilized this grout sealer. I added it to the grout as I mixed prior to floating into joints. A year later, no mold or so much as an imperfection in my tile grout!!! Superior protection against water intrusion and mold/mildew on grout! Would definitely purchase again! Easier than spraying or brushing on a grout sealer after the grout is installed.
