A lot of homeowners aren't aware that you need to have different types of drywall for bathrooms and areas that collect a lot of moisture. There are a few different options depending on your situation, and one of our Ottawa Drywall contractors would be a good resource for finding out exactly what you need for you project. In the meantime, below we're going to go through some of the different types of drywall you could, or should use in your bathroom.
One of the primary concerns when selecting drywall for a bathroom is its ability to withstand moisture. Moisture-resistant drywall, commonly known as green board or green drywall, is specially designed to resist moisture penetration and minimize the risk of mold and mildew growth. Its gypsum core is treated with water-resistant additives and covered with a moisture-resistant paper facing. Green board is an excellent choice for areas prone to high humidity, such as bathrooms, as it offers enhanced protection against moisture-related issues.
For areas of the bathroom that are directly exposed to water, such as shower walls or bathtub surrounds, cement board is an ideal option. Made from a combination of cement and reinforcing fibers, cement board is highly resistant to moisture and offers exceptional durability. It is specifically engineered to provide a solid base for tile installations and acts as a reliable moisture barrier. Cement board is known for its ability to withstand frequent water exposure, making it an excellent choice for wet areas in the bathroom.
Paperless drywall, also known as fiberglass-faced drywall, is another suitable option for bathroom applications. Instead of traditional paper facing, it features a fiberglass mat that provides enhanced resistance to moisture and mold. This type of drywall is particularly beneficial in areas prone to high humidity or where water exposure is likely, as it eliminates the organic paper surface that can serve as a food source for mold growth. Paperless drywall offers improved moisture resistance and is an excellent choice for maintaining a dry and mold-free bathroom environment.
In addition to choosing the right type of drywall, you've got to pay attention to the joint treatment. Bathrooms require airtight seams to prevent moisture penetration and potential mold growth. Opting for mold-resistant joint compounds and using mesh tape instead of paper tape can further enhance the moisture resistance of the drywall system. Applying a waterproofing membrane or sealer over the joints and corners adds an extra layer of protection, ensuring a watertight bathroom environment.
Conclusion
Selecting the best type of drywall for your bathroom is vital for maintaining a durable and moisture-resistant space. Moisture-resistant drywall, cement board, and paperless drywall are all excellent choices, depending on the specific application. Additionally, paying attention to proper joint treatment and utilizing moisture-resistant products will further enhance the longevity and performance of the drywall. By making informed choices and following best practices, you can create a bathroom that not only looks great but also stands the test of time.
