9mm Moisture resistant Gypsum Board Drywall Waterproof Gypsum Board Ceiling Plaster Board
Introduction of 9mm Moisture resistant Gypsum Board Drywall
--->Moisture/Waterproof Gypsum Board
Water-resistant gypsum board, also known as green board or moisture-resistant gypsum board, is a building material used for walls and ceilings in areas where moisture is likely to be present, such as bathrooms, kitchens, and laundry rooms.
Water-resistant gypsum board is made by adding a layer of moisture-resistant material to the core of standard gypsum board during the manufacturing process. This moisture-resistant material is typically a fiberglass mat or a specially treated paper facing.
Water-resistant gypsum board is designed to resist the growth of mold and mildew and can withstand exposure to moisture without deteriorating. However, it is not designed to be completely waterproof and should not be used in areas that will be in direct contact with water, such as shower stalls.
Features of 9mm Moisture resistant Gypsum Board Drywall
Waterproof Gypsum Board has high waterproof performance, with surface water absorption ≤ 160g/m2 and water absorption rate of about 5%.
- Water-resistant core: Waterproof gypsum board has a core made of water-resistant materials, such as fiberglass or plastic, which prevents it from absorbing water.
- Moisture-resistant facing: The facing of waterproof gypsum board is made of moisture-resistant materials, such as vinyl or fiberglass, which prevents water from seeping through the surface.
- Mold and mildew resistance: Waterproof gypsum board is treated with additives that inhibit the growth of mold and mildew, which are common problems in damp environments.
- High strength: Despite its water resistance, waterproof gypsum board is still strong and durable, making it suitable for use in high-moisture areas.
- Easy to install: Waterproof gypsum board is easy to cut and install, making it a popular choice for DIY projects and professional installations.

Application of 9mm Moisture resistant Gypsum Board Drywall
- Bathroom walls and ceilings: Since bathrooms are prone to moisture and humidity, 9.5mm Water Resistant Plasterboard can be used to create a moisture-resistant barrier on walls and ceilings. This will help prevent the growth of mold and mildew, which can be harmful to health.
- Kitchen backsplash: 9.5mm Water Resistant Plasterboard can be used as a backing material for kitchen backsplashes. It can be installed behind tiles or other decorative materials to provide a moisture-resistant barrier and protect the wall from water damage.
- Laundry room walls: Laundry rooms are also prone to moisture, especially if they are located in the basement. 9.5mm Water Resistant Plasterboard can be used to create a moisture-resistant barrier on walls to prevent water damage and the growth of mold and mildew.
- Basement walls: Basements are notoriously damp and can be prone to flooding. 9.5mm Water Resistant Plasterboard can be used to create a moisture-resistant barrier on basement walls to protect against water damage and mold growth.
- Outdoor walls: 9.5mm Water Resistant Plasterboard can be used as an external cladding material for buildings that are located in areas with high levels of rainfall or humidity. It can provide a moisture-resistant barrier and protect the underlying structure from water damage.
