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.

Overlay Flooring Moisture Barriers

If you’re looking to protect your flooring from excess moisture, consider using overlay moisture barriers. These barriers are materials that are rolled out and installed under the flooring. They can be made from paper, tar, or plastic and are suitable for use on a variety of subfloors, including OSB, particle board, plywood, and concrete. One of the advantages of overlay moisture barriers is their ease of use. They can be spread out quickly, making them a convenient option for flooring projects. Whether you’re a professional contractor or a DIY homeowner, overlay moisture barriers can be an effective choice.



Roll on Flooring Moisture Barriers

Another option for protecting your flooring from excess moisture is a roll-on moisture barrier. These barriers are applied to the subfloor as a liquid or semi-liquid and are often used over concrete to prevent moisture from entering the flooring. Roll-on moisture barriers come in two types: one-part and two-part products. One-part barriers can be applied without the need for mixing with a catalyst or hardener, while two-part barriers require the use of a catalyst for proper application. Two-part roll-on moisture barriers are generally considered more effective at protecting against moisture, but they can be more wasteful as any leftover product will harden and become unusable. When selecting a roll-on moisture barrier, consider the specific needs of your project and the potential advantages and disadvantages of each type of product.

Each option does the job effectively. However, if you have RH of over 85% on the floor or a higher than nromal moisture reading it is ideal to use a moisture blocker that overs 85%+ or higher moisture contents. The liquid barriers are superior if you have a space with 85% or 10+ moisture.
