Moisture Resistant Plasterboard

What is Green Plasterboard?

Commonly known in the trade as green plasterboard, moisture resistant plasterboard is easily identified by its distinctive green paper face. The green colour shows that the board has been treated to withstand moisture better than standard plasterboard.

Benefits of Water Resistant Plasterboard

• Water repellent additives throughout the core and paper liners

• High resistance to deformation in humid environments

• Suitable for decorating, tiling or plastering

• Compatible with a range of paints and finishing products

• Available with tapered or squared edges for different finishing requirements

• Can be fixed using screws that won't rust or adhesive

• Gypsum and paper materials are fully recyclable

• Suitable for both single and multi-layer board applications

• Same expected lifespan as the room when correctly installed

Where to Use Moisture Resistant Plasterboard

Moisture resistant plasterboard is the recommended board type for any interior space with high humidity such as bathrooms, en-suites, kitchens, utility rooms and cloakrooms. It's suitable for both wall and ceiling applications in these areas.

While not fully waterproof, water resistant plasterboard significantly slows moisture absorption, making it suitable for areas with high humidity and occasional water exposure. For areas with direct and constant water exposure (such as wet rooms or showers), specialist tile backer boards are recommended.

Installation, Fixing and Finishing

Waterproof plasterboard is straightforward to install using standard drywall methods, making it a practical choice for both trade professionals and DIY projects.

Boards are typically fixed to either timber studs or metal framing systems, depending on the environment. In areas such as bathrooms or kitchens, metal framing systems are generally recommended as they offer greater resistance to moisture and won't warp over time.

Moisture resistant plasterboard supports a range of finishes to suit your project. Boards can be skimmed with plaster, painted using a moisture-resistant coating, or tiled directly using a suitable waterproof adhesive. For tiled finishes, ensure the board specification supports the weight of your chosen tile and adhesive system.
