Moisture resistant Gypsum Board
Water-resistant gypsum board, also known as greenboard or moisture-resistant gypsum board, is a type of drywall that is specially designed to resist moisture and humidity. It is commonly used in areas where moisture is present, such as bathrooms, kitchens, laundry rooms, and basements.
water-resistant gypsum board is not completely waterproof but it is designed to resist water and moisture for a certain period of time, allowing for proper cleanup and prevention of mold growth. It is important to note that water-resistant gypsum board is not suitable for areas that will be directly exposed to water, such as shower stalls or saunas.
