Manufacturers produce drywall that is effective in high-moisture areas, and it also can inhibit the growth of mold. However, such products often cost more than regular drywall, and they can come with a list of limitations that make them unsuitable for some projects. Read on to learn more.

Instructions

Difficulty: Moderate

Step1

Make sure you're using a product for its intended purpose. Drywall that is water-resistant is often called green board. It has been around for a long time and is recognizable by its green-colored paper facing. It can stand up to limited amounts of water. However, waterproof wall materials typically won't be harmed by water or water vapor.

Step2

Understand green board can be effective behind sinks and toilets, but not behind ceramic tile in tub and shower areas. Water can penetrate ceramic tile grout and deteriorate the paper facing of the green board.

Step3

Know that there are gypsum-core products that are considered to be waterproof. These waterproof panels can be used behind tile and in areas where water is consistently splashed on a wall.

Step4

Consider that paperless interior drywall can inhibit mold growth, but note the manufacturer's statements and warranty for paperless products. Specifications for these products often say the drywall is mold-resistant and moisture-resistant, not mold-proof.

Step5

Note other limitations of paperless drywall. Manufacturers' instructions may tell installers to keep the drywall from being exposed to excessive moisture. Additionally, manufacturers also acknowledge that no material can be considered mold-proof due to varying conditions. This could mean mold problems won't be solved if the paperless drywall is being used to replace a product on which mold grew.
