--->Moisture/Waterproof Gypsum Board
Waterproof gypsum board is a building material specifically designed to resist moisture and water damage. It is usually used in areas with high humidity, such as bathrooms, kitchens, and laundry rooms.
The board is made of a special type of gypsum core, which is mixed with waterproof additives and then covered with waterproof decorative materials. The decorative material can be paper, fiberglass, or a combination of both, which can provide additional moisture protection.
Waterproof gypsum board is usually green, which makes it different from standard gypsum board. Green comes from the waterproof additives added during the manufacturing process.
In addition to waterproofing, the board also has other ideal characteristics, such as fire resistance, sound insulation, and ease of installation. It comes in different sizes and thicknesses to meet different building needs.
Waterproof Gypsum Board has high waterproof performance, with surface water absorption ≤ 160g/m2 and water absorption rate of about 5%.
Water-resistant plasterboard is a versatile material that can be used in a wide range of applications where moisture resistance is essential. It is important to note that while water-resistant plasterboard is more resistant to moisture than regular drywall, it is not completely waterproof and should not be used in areas where it will be submerged in water.

Outdoor spaces: Water-resistant plasterboard is also suitable for use in outdoor spaces that are exposed to moisture, such as covered patios or outdoor kitchens.
Bathroom walls and ceilings: Water-resistant plasterboard is an ideal material for bathroom walls and ceilings, as it can withstand high levels of moisture without deteriorating. It is resistant to mold and mildew, which are common problems in bathrooms.
Kitchen backsplashes: Water-resistant plasterboard can be used as a backing for kitchen backsplashes, as it is resistant to moisture and can protect the wall from splashes and spills.
Laundry rooms: Water-resistant plasterboard is also suitable for laundry rooms, where high levels of moisture are common due to washing machines and dryers. It can help prevent mold and mildew growth in these areas.
