Rustic Floor Supply offers flooring moisture barriers at our Spokane, Washington location. Moisture barriers are utilized to stop humidity from the subfloor from reaching the flooring above it. There are two main types of moisture barriers: roll-on and overlay. Both of these types are effective at reducing moisture transmission and can be used based on the specific needs and requirements of the project. No matter which type you choose, a moisture barrier will effectively reduce moisture and protect your flooring from damage.
