What is Blue Board Drywall?

Blue board drywall is made from gypsum and is covered with a blue paper. This unique paper is designed to bond with plaster, making it ideal for those seeking a smooth and durable finish. The absorbent surface of blue board allows for better adhesion of veneer plaster, providing a harder and more resilient surface compared to regular drywall.

Advantages of Blue Board Drywall

1. Moisture Resistance: Blue board is specifically designed to handle moisture better than traditional drywall, making it suitable for areas like bathrooms and kitchens.
2. Smooth Finish: When finished with veneer plaster, blue board offers a significantly smoother and cleaner appearance than standard drywall.
3. Durability: The plaster applied over blue board creates a hard surface that is less prone to dents, scratches, and other damages.
4. Faster Installation: The installation process is quicker as blue board does not require the mudding and sanding typical of regular drywall.
5. Sound Proofing: Blue board combined with plaster can reduce sound transmission, making it a good choice for multi-family homes or shared walls.

Disadvantages of Blue Board Drywall

1. Cost: Blue board can be more expensive than standard drywall due to its specialized purpose.
2. Installation Complexity: While the initial hanging is straightforward, finishing with plaster requires skill and experience, making it less suitable for DIY beginners.
3. Limited Use: It’s not ideal for every application, particularly where traditional drywall may suffice.

Installation Process of Blue Board Drywall

Step 1: Preparation

Before beginning installation, ensure that the area is clean and free from debris. Measure and cut the blue board panels to fit the wall space, just like standard drywall. Use a utility knife for clean cuts.

Step 2: Hanging the Panels

Secure the blue board with drywall screws or nails. Maintain a uniform distance between fasteners to ensure stability. Joints between panels should be tightly aligned to minimize gaps.

Step 3: Taping and Plastering

Once the panels are hung, apply a special tape to the joints. Instead of using joint compound, cover the taped seams with veneer plaster. This process can be completed in one or two thin layers.

Step 4: Finishing Touches

Allow the plaster to dry thoroughly before moving on to painting or other finishes. The drying time can vary, so consult the plaster manufacturer’s instructions for optimal results.
