It's been a couple of years since the slab was poured - time to seal it. Can anyone recommend a locally available product or even a product type/class? I'm thinking that the cheap $15/gallon "Concrete Sealer" that I saw at Rona isn't the product I want to use.

Go to the north end of Gordon Dr. across the former tracks, on the right hand side. I forget the name of the business but they have all sorts of concrete sealers there. Very high quality ones. It is critical to know what yours was first sealed with though.
