Black Diamond Stoneworks Granite Sealer: Seals and Protects. Marble Sealer Protector. Granite, Marble, and Travertine Countertop Sealer for All Stone Countertops. Enhance Your Stone’s Natural Beauty.

This was recommended by the kitchen installer as a way to make doubly sure that the granite is sealed. Easy to use, quick, definitely made a difference. He said to do it every six months.

This is a good sealer. It worked really good and was easy to apply to my countertops. I was skeptical about how I was going to tell when it was soaking in since it’s a granite top, but as I applied, I can tell when I didn’t need to apply anymore, and the counter was absorbing it. I’ve use this twice just to make sure I’m on the part and this seems to work great I highly recommend for the price and the quality of the product. My countertops look shiny and revitalized again.

Product works well. I seal my granite around my bathroom sinks. No more water or soap scum build since I've used this.

This is my second bottle of this granite sealer. It goes on very easily and protects the granite from moisture.

Followed directions, sprayed on rubbed until absorbed, spay again, rub and repeat the process until it doesn't seems to take any more. It made my counters shiny and I was happy....until about two weeks later when something greasy was left behind at some point and the marble absorbed it leaving a dark stain. Looks like it will need resealing more frequently than I had hoped.

This product worked great to re-seal my 2 year old granite counter tops and new marble occasional tables. Since the marble was new, I didn't see much difference in appearance but, I could definitely feel the difference after applying this sealer. With the granite counters, I could also feel the difference and see a (slightly) higher sheen. Please note, this is not a polish and is really only a sealer. Don't expect shiny results after using this product. If your granite (or other stone) is dull, chipped or very porous, you may need to have it honed and buff-polished first. Then use this product to keep it sealed from stains and water marks. FYI: When using this sealer, don't let it completely dry on surfaces where it will create a hazy coating which will be difficult to remove. Remember, this is a sealant which is intended to penetrate the stone creating a hard sealed effect. After applying a light coat, wait a minute or two, then buff dry with a clean, soft cloth. Continue until sealer is completely dried off. If your surface absorbed the sealer within a minute, you may need a second application. Wait at least an hour for a second application and always wait at least 2 hours after you finish before using your counters or other stonework.

I rarely leave reviews, but I kept reminding myself that I had to leave one for this stuff because of the night and day difference it gave me. Before I used this sealer on my white quartz countertops every single drip of anything other than water would go straight into the stone and start to stain it. I spent a long period of time trying to buff out simple coffee stains, but the day I dripped red wine on the countertop I knew I had to do something. I bought this sealer and followed the directions exactly as the video in the Amazon ad showed. I bought a paint applicator for doing edges around the house and used that to rub the sealer in over 2 applications. If you follow the directions it's very easy to do and doesn't take all that long. Now I still get coffee on my countertop, nothing is going to stop that, but when I do I can wipe it off with a simple paper towel and it comes off. I am amazed how well this works. It solved a very big problem and I would recommend to buy to anyone.

It’s a good product it keeps the stone bright

Not eligible for return! Beware

This sealer works exactly the way it's supposed to. Easy and clear instructions with great results! My granite countertop is sealed well and the water beads up! I went over the countertops several times before the granite didn't absorb the sealer anymore. Then (according to instructions) dried it with a clean cloth and ended up with a great seal and shine.

No result as expected

Caro e inefficace e non in italiano RESO

Very pleased with this product and it does what is says and seals the surface of my granite worktop
