Professional Tips for Installing Drywall in High-Moisture Areas

When it comes to drywall installation, high-moisture areas like bathrooms, kitchens, basements, and laundry rooms present unique challenges. Installing regular drywall in such spaces can lead to mold, mildew, and water damage. If you're planning a project in a high-moisture area, it's important to know the proper techniques and materials to ensure your drywall can withstand the environment. At Calgary Drywallers, we specialize in handling these tricky areas with expertise and precision. Here are some professional tips to help ensure your drywall installation lasts for years to come.
1. Choose the Right Drywall Material
Standard drywall, also known as gypsum board, is not suitable for high-moisture environments. Instead, use moisture-resistant drywall. Some of the best types include:
- Green Board Drywall: This drywall is water-resistant and often used in bathrooms, basements, and kitchens. While not waterproof, it can handle higher humidity levels and occasional exposure to moisture.
- Blue Board Drywall: Blue board is specifically designed for areas where veneer plaster is applied. It offers resistance to mold and mildew, making it a great option for moisture-prone rooms.
- Cement Board: Also known as backer board, cement board is extremely durable and 100% moisture-resistant. It’s ideal for areas that are in direct contact with water, such as shower walls.
- Purple Drywall: This is an advanced moisture- and mold-resistant option that offers superior performance in high-moisture areas. It’s commonly used in bathrooms and laundry rooms for added protection.
2. Seal All Gaps and Joints
Even with moisture-resistant drywall, water can still find its way through small gaps and seams, leading to damage over time. To prevent this, it’s crucial to properly seal all gaps and joints using a high-quality joint compound. Make sure to apply tape over the seams and coat it with a waterproof sealant or mold-resistant compound.
Additionally, caulk around windows, doors, and any other openings in the drywall to prevent moisture from seeping through these vulnerable spots.
3. Use the Right Fasteners and Spacing
Moisture-prone areas often see expansion and contraction due to temperature and humidity changes. This can lead to cracking or warping if the drywall isn’t installed correctly. Use corrosion-resistant fasteners, such as stainless steel screws, to prevent rust from moisture exposure. Ensure that fasteners are spaced correctly (typically 16 inches apart) to prevent the drywall from sagging or becoming loose over time.
4. Install a Vapor Barrier
In very high-moisture environments, such as saunas or steam rooms, installing a vapor barrier is essential. A vapor barrier is a layer of plastic or foil that goes behind the drywall to prevent moisture from reaching the wall structure. It helps protect the framing and insulation from water damage while improving the overall lifespan of the drywall.
5. Proper Ventilation is Key
Ventilation is a critical factor in maintaining drywall in high-moisture areas. Ensure that the space has adequate ventilation, including exhaust fans, air vents, or dehumidifiers, to control humidity levels. This will reduce the likelihood of mold and mildew forming behind the drywall.
6. Consider Waterproof Paint or Primer
Once the drywall is installed, consider applying a waterproof primer or paint as an added layer of protection. These coatings help seal the surface of the drywall and prevent water from penetrating through, keeping your walls looking fresh and damage-free.
7. Regular Maintenance is a Must
Even with proper installation techniques, drywall in high-moisture areas requires regular maintenance to ensure it remains in good condition. Be on the lookout for signs of water damage, such as discoloration, warping, or peeling paint, and address any issues immediately to prevent further deterioration.
