Mold Resistant Building Materials

When it comes to building your home, it’s important to be smarter. Maintenance can be a real downer when you have to do it year after year. So the material you choose should last long and be able to fight off anything that can damage it like water, mold, and mildew.

Today, we discuss some mold resistant building materials you can apply in your present or future home.

Mold Resistant Insulation: Even though fiberglass is inherently resistant to mold, there are companies producing insulation that has been treated with a fungicide. Companies like Nu-Wool manufacture a Premium Cellulose Insulation that is one of the few insulation products which contains a fungicide registered by the Environmental Protection Agency (EPA). In addition, the fungicide being used by Nu Wool is low in toxicity making it a safer choice when considering treated insulation.

Mold Resistant Paint: More and more, there are paints being offered that contain fungicides. The point of using a mold resistant paint is to discourage the growth of mold on the paint surface (the wall). However, it should be noted that if there is already mold present before the paint is applies, the paint will not kill the mold; any mold must be removed at its source before paint is applied. An example of a great mold resistant paint is “Perma-White®” by Zinsser. It is guaranteed to prevent the growth of mold on the paint film for at least 5 years as shown in independent laboratory tests.

Mold Resistant Carpet: Carpets made of Olefin (polypropylene) fibers or acrylic fibers offer resistance to mold growth, although, acrylic carpets are being less used in today’s market because of their poor resilience. Polypropylene carpets can be found almost anywhere today.

Mold Resistant Drywall: This type of drywall has fiberglass facing instead of the traditional paper facing. The use of fiberglass removes the “organic material” aspect from the drywall (mold feeds on organic material). Even though mold resistant drywall does not completely prevent mold growth, it greatly reduces occurrence.

Mold Resistant Sealant: Easily applied to wood, OSB, concrete, stucco, brick, tile, gypsum, and other surfaces in the home, mold resistant sealant is a protective coating that has been blended with anti-microbial chemicals. Mold resistant sealants come in either spray or non-spray forms. Brands like Fiberlock IAQ 6040 Mold Resistant Sealant® can be used on wood, OSB, wallboard, concrete and other construction materials to withstand the moist, humid conditions that provide the ideal environment for fungal growth.

Mold Resistant Caulk: On the market, this tends to be sold as “Mildew Proof” or “Mildew Resistant” caulk. Because mildew isn’t necessary the mold you see in your home, (See The Difference Between Mold and Mildew), we choose to call it Mold Resistant Caulk. Manufacturers like Dap® have introduced products like Kwik Seal Plus Adhesive Caulk with Miocroban®. The caulk is treated with fungicide so it helps prevent mold growth on the caulk as well as stains and odors. In addition, the caulk emits low VOCs.

While there are more products being manufactured to help resist mold growth, it is important to note that if there is a mold problem to begin with, the mold must be removed at its source. Nevertheless, mold resistant building materials provide great building blocks for a mold-free property and help prevent having to endure the process of mold removal. Especially when used in high-humidity and mildew-prone areas, mold resistant materials can significantly increase indoor air quality as well as help maintain a mold-free environment.
