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

Actually worked pretty good. The area I am working on was not sealed properly in the beginning. I will reapply often. I like this product.

The sealer was easy to apply and left the granite grave marker looking wonderful.

It’s a good product it keeps the stone bright

Excellent product

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.

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.

Definitely follow the directions on this as that is key. let the product sit but not sit too long. You also need to make sure you buff the product off before it dries too much. The humidity and temperature of the air and time of day plays a role in the outcome.I did this at night as it was much cooler and didn't have time in the day but i think early mornings is best when you get the most light and its cooler so it won't dry immediately after putting it on. I did two coats and the quality of this product is evident. It brought back that shine that the old stone was missing.

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