Water-Resistant Gypsum Backing Board
PABCO® WATER CURB® is a moisture-resistant treated core product and is intended to be used in rooms with intermittent high humidity levels such as in bathrooms, kitchens and laundry areas. PABCO WATER CURB shall not be used in extremely critical areas such as saunas, steam rooms, locker/gym shower rooms, or indoor pool enclosures.
PABCO WATER CURB panels are manufactured in 1/2" and 5/8" thicknesses and in lengths of 8' or 12'. It has a water-repellent paper (blue-green face paper and gray back) both treated chemically to provide a water-repellent surface. The core of the PABCO WATER CURB gypsum panel is chemically treated to make it water-resistant. Tapered edges provide a recessed area that allows tape and joint treatment to be used to create a monolithic (flat) surface.
PABCO WATER CURB panels are flexible and can be attached with nails or screws. The gypsum core provides natural resistance to the spread of fire.
