Hi all, I am going crazy trying to find a way to change the color of the Quikwall product that I used to cover the cinderblock foundation to our patio. I had tried to match the stamped concrete slab on top but it turned out a little to orange so I want to darken it to a dark brown or grey. The biggest problem seems to be finding a product that will not seal because moisture coming up from the ground below needs to be able to escape...I don't want it trapped against foundation of house. I have called Boomers concrete in Detroit, a local block and concrete company and went to Sherwin Williams and none of them seem to have a product that will not seal. The funny thing is that I have heard that a "breathable sealer" should be used, but isn't that an oxy moron? Is there such a thing? Any pros out that that can help with a product recommendation? I really don't want to go over this with another coat of quickwall, attempting to get a better color this time! Thanks!
