I didn't read the specs on the Behr products, do they penetrate the concrete? The main reason I chose the Seal Krete is because it was what was available at Sherwin Williams locally - closest Home Depot is 40 miles away. We do have a Lowes but I don't think they carry Behr products?
When I described to the salesman at SW what I was looking for he told me all the brick masons in the area use Seal Krete, because it penetrates the concrete/brick it actually forms a stronger bond. However, the ONE lesson I learned the hard way is it's NOT waterproof, only water resistant. I used it on the inside of my hollow concrete sphere and when I added water the dark green interior turned milky where the water is.
It's perfect for most projects but won't work for anything "submerged".
