StoneTechHeavy Duty Sealer, 1 Gallon (3.8L) Bottle

I just sprayed it on the old brick walls so don't know yet about how well it will seal them but it was easy to spray and cleanup.

Granite and Marble sealer works well

I bought 6 gallons of this product to seal the 3200 square feet of travertine flooring I had installed. I was afraid that 6 gallons would not be enough, but I ended up with a half gallon left over. The installers applied the sealer and they did not have any problems with it. As can be expected, there was a strong chemical smell as it dried and for a little while after. It was smelly, but not overwhelming and it went away after about a day. The sealer brought out the colors in the travertine without making the tile appear wet. I am happy with this product.

I purchased this stone and tile sealer (and companion cleaner) in May 2012 from Terrazzo & Marble Supply Company through Amazon. We just put in new granite kitchen counters. Although I knew I wouldn't need to seal the counters for a year at least, I wanted to have the supplies on hand. The containers arrived with small dents in the front bottom edge. I put the container in the mud room over cat litter boxes. Weeks or a month or two later, while cleaning the litter boxes I noticed the shelf was wet and the litter was nearly all clumped. (Must have happened rather suddenly because I clean the litter box every day or two.) I realized the only liquid nearby were the cleaner and sealer containers. It was kind of scary since the sealer is a hazardous product. I couldn't see a hole in the thick container but the dent may have been the cause. I quickly transferred the sealer to the only clean container I had, a plastic milk container and then put the milk container in a bucket as extra protection and moved it to the basement. Fortunately I did because the milk container eventually leaked. Perhaps the sealer corroded the lighweight milk container plastic. I just transferred the contents to glass bottles. Very annoying to buy an expensive product with inferior packaging that I plan on using for a long time. Finally, I'm not sure if it was the dent that caused the leak. If it was, it is not clear to me who would be responsible (Amazon, Terrazzo, or DuPont) because I don't know when the dent occurred prior to it arriving at my house. In hindsight I should have asked for a refund (because I couldn't return a leaking container of chemicals via mail.) Note: I have yet to use the product! But even if it is excellent, I wouldn't raise my rating too much, if at all.

I’ve been using this product for the last few years, unfortunately it’s hard to source it locally, thank God for Amazon, I could still buy this product, hands-down number one sealer I’ve ever used. Worth every penny and lasts a long time.

very good thanks

Amazing product, granite tops look great and any liquid spilled instantly beads instead of absorbing into the granite

Seems to be what all local stone/marble guys recommend

Works great
