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

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, prompt delivery.

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.

After following the directions and rereading the directions and applying the sealer my countertops look smeared not polished. Now I’m stuck with how to fix it. But they are probably sealed.

This Black Diamond granite sealer worked perfectly on my kitchen countertops. After several years of sealing my countertops every year, I stopped applying sealer for about ten years, and my granite was looking a little worn out. I applied Black Diamond sealer, and they look almost new again.

I assume most sealers are easy to apply. I applied two coats on new granite, water beads as expected. I would recommend. There are probably less expensive sealers. I purchased this product because of the 2n1 cleaner sealer maintenance type product was a good price.

I bought this to seal an outdoor concrete coffee table. I applied 2 coats and so far so good. I followed the instructions and wiped the product in a circular motion avoiding streaks. It says do not allow product to dry on the surface which made me wonder if it meant do not allow it to dry in puddles on the surface? Of course the product is supposed to dry. I wish I had done this 2 years ago to avoid the weather damage. Way easier than constantly covering with a tarp.

The product was easy to apply with some caveats. If the area to be sealed is exposed to the sun, I suggest you reduce the area of application to 2/3 of the suggested area as the product dries very quickly in the sunlight. If it appears to be drying too quickly reapply the product using a kitchen sponge followed by a wipe down with a dry clean cloth. If you find streak marks repeat a quick application over the marks followed by the dry cloth. The product was applied on granite, marble, and cultured marble surfaces and behaved the same on all surfaces. Three coats of product were applied allowing for the suggested drying time between coats. I am trusting that the product will perform for at least one year. After a 24 hour waiting period a granite polish was applied on all surfaces and the surface finish was excellent. After the usual kitchen use, the surface came back to the original lustre obtained after the product application.
