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.

Excellent product, prompt delivery.

It’s a good product it keeps the stone bright

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.

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.

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

I’ve used this several times on a new white marble top table and I tested it by setting a cold can of sparkling water on it and it still leaves darkened rings. Thankfully it’s just water so it evaporates, but this didn’t work for me. I followed the instructions and did multiple coats. Maybe this is only intended to top off an already sealed surface?

I use a lot of their other products and stand by them but the sealer is absolutely fantastic. It is fairly easy to put on and stinks to high heaven but the result is as. close to professional as one could get. I would put children and pets out of the house when you use it.

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.
