I wanted stucco walls for my new garage, but the contractor didn't design it correctly - now I have hardyplank over frame with an exposed cinderblock foundation. The cinderblock gap between the hardyplank and the concrete footer ranges from a few inches to a couple of feet. Painting the garage, I'd still like to make the foundation look smooth, like stucco. I'm told there's a paint/mortar mix that can be applied as a thin layer, and will fill in the mortar joints on the cinderblock, leaving a smooth texture.
Any suggestions?
