Hardwood sleeper floor on slab
thanks gary. I've seen the article before. But it seems they are referring to flooring that's directly on the slab. I currently have sleeper floors. So i guess my question is, does being 5" above slab make any difference? I guess there would need to be some ventilation in the 5" space for it to work right?
Before starting this project, I actually had plans to use the dimpled plastic membrane as vapor control as described in the article. I was going to use Delta-FL on slab, then xps foam, then plywood, and then any flooring I want. But after starting the project, I realize the slab is not level (sloped for drainage) and the sleeper joists are shimmed (I'm sure painstakingly) to compensate for the slope. Leveling the floor is a much bigger job than I want to do, so I was trying to find a way to reuse the sleeper floor.
Also, the article mentions an epoxy to seal the slab, but no product details. Do you know what those products are? I've seen epoxied garage floors, but I don't think that's the same type of epoxy.
