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.

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.

Excellent product, prompt delivery.

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
