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 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.

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.

My counter absorbs(ed) turmeric and matcha and would stain. This product was easy to use but left streaks. I couldn’t tell if it soaked in or not. I went behind it with a wet cloth and a dry cloth and the streaks went away. It has been a few weeks but I haven’t spilled anything that would have previously stained the counter so I can’t say how well it protected it.

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.

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 sealer was as adverised, easy to use, and effective. The distributer provided a UTUBE link that showed how to apply the product, which was helpful. As our granite had not been sealed in many years and was looking dull, I was concerned that I would not be able to seal and restore the luster. The sealer is NOT a polish, so the process to seal and restore luster is a three part process. First use a quality cleaner on the granite; paper towel wipe-up is fine. Then apply the sealer according to directions. I applied two coats, waiting an hour between coats. Use clean, dry cloths to wipe the granite. Finally, after waiting two hours after last seal, apply polish ( I used RXock Doctor Granite Polish spray ) To buff the polish after it had dried I used an electric hand drill with a polishing disc and clean cloths, and then manually buffing as needed. Be sure to protect floors, cook tops, and back-splashes. Our granite now has a nice luster and is properly sealed.

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

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
