Great product

I re sealed my existing countertops and the product rolls on very well. Followed the directions for rolling and it turned out perfect.

Dave Miller

I will use nothing but Rock Top when I seal Concrete Countertops. Preference to spray or roll is totally yours as the results of both techniques are flawless as long as a person can follow application directions. The finished sealed surface is always nothing short of Amazing!!!

Lance Nelson

Great product that applies easily

Great Sealer

There is no perfect sealer for concrete. I have been using Rocktop for several years now. The application process can be tricky depending on how you choose to apply it, but it looks phenomenal when it is finished. Like all concrete sealer it will acquire wear but it is easy to reapply and if taken care of properly it will hold up well. I did a 145 sq foot countertop surface in a bar a few years ago and it has held up just fine. If you educate the customers on some of the dos and don'ts it works great. I'd recommend this product for countertops. I just put it on my first outdoor kitchen job and I'm curious to see how it holds up over time. Great product!
