I'm not sure in your exact application as it is a countertop, however, I will offer what I have found in my recent search of "polyurethane over an old brick wall" in our home that we recently discovered, and I had the same question. This is what I found and where I found it. -- Hope it gets you started. Good Luck! " Q: (from Donna in San Diego, California): We just finished removing the plaster from the chimney stack in the kitchen. It looks great but what should we do to the exposed brick? Jay: There are a couple products you can buy to seal brick. You may also want to try simple satin-polyurethane. The same product you use to protect wood. The brick may darken slightly as it soaks up the 3 to 4 coats, so don't be surprised. Remember to use it on the mortar as well. Above all make sure the area is well ventilated and you let each coat dry thoroughly. http://www.diynetwork.com/diy/ho_maint/article/0,,DIY_13948_3465461,00.html
