If you own wood flooring, you no doubt know that you want to keep water off the top of it. While there’s no need to treat it with kid gloves, you don’t want to encourage any warping or staining! Indeed, certain types of flooring and spilled liquid don’t mix—but no type of flooring does well with liquid beneath it, which is where moisture barriers come into play.

If You’re Installing Over Concrete

“Solid concrete” is a common phrase, but it’s actually slightly inaccurate! While concrete is sturdy, of course, it’s porous in reality—filled with small holes. These small holes make this subfloor type extremely vulnerable to moisture accumulation and, thus, direly in need of a moisture barrier should any type of flooring be added atop.
