Product mixed very well with grout but time will tell if it blocks stains.

Rated 2.0 out of 5.0 by microJiant Very difficult to work with
I added this to PolyBlend un-sanded grout to grout some mosaic tile. I usually use the Grout Boost additive, but it was not in stock. The StainBlocker additive was mixed with water precisely per the directions for un-sanded grout and was mixed to the usual consistency with the proper wait time. It floated onto a small area ok, but quickly began thickening and was extremely difficult to sponge off any excess grout, even with the scrubber side of the sponge I was using.
This increased the application time, the amount of grout needed (due to waste), and my frustration level significantly. My advice is to stay away from this product. If you decide to use it anyway based on other reviews here, I'd love to be there to tell you "I told you so"!

Rated 5.0 out of 5.0 by Larry Stainblocker 12 oz Additive For Grout
It's very easy to use. Just add it when mixing. It helps to keep the color true and to keep stains from soaking into the grout.

I used this for the first time about a year ago. I used it on a kitchen back splash. The joints still look brand new, and that's in a kitchen, behind a range, and behind the sink. I wouldn't ever use the old joint additive ever again. It doesn't clean up like this product. Plus you just add it in your mix and you're done, you don't have to go back after it dries like the old.

Rated 1.0 out of 5.0 by Blocz Doesn't seal grout
I bought this as recommended by HD associate. Followed instructions exactly (replace half of the prescribed water for grout mixing with this product). Grout has set up for a week and water soaks right in. Waste of money.

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.
