Moisture Resistant Core Type X

Product Description

Product Description

Cabot Moisture Resistant Type X Board consists of a water-resistant core of noncombustible gypsum rock sandwiched between a green, water-resistant face paper and a water-resistant brown-back paper. Both front and back paper are made from 100% recycled paper. The face paper is formed along each edge, wrapped around, tapered and sealed to the back paper. This produces a strong yet flexible panel which meets most commercial/residential construction requirements for wall and ceiling substrates. Cabot Moisture Resistant Core Type X Board is manufactured in 5/8" Type X Core for use in UL/ULC fire-rated assemblies. 

The panel is designed to be used in high moisture areas such as bathrooms, kitchens, and laundry rooms. The board comes from the factory as a ready-to-finish product. After installation, the ends, edges, corners and fastener as a ready-to-finish product. After installation, the ends, edges, corners and fastener heads can be concealed with joint treatment systems to produce a smooth seamless surface prior to final decoration. The panel can also be used as a base for ceramic tile, or laminate panels. It should however not be used behind a finish that comes in direct exposure to running water or continuous high humidity.

Adequate ventilation must be maintained during installation and finishing and curing process. Board application must be in accordance with the applicable UL/ULC Test. 

Decoration

Decoration

Cabot Moisture Resistant Gypsum Board is designed to accept most types of paints, texture and wall covering materials. The surface should be primed and sealed with a full bodied quality latex primer before applying a decorative material. If glossy paints are used in areas such as kitchens or bathrooms, a Level 5 finish is recommended to reduce highlighting or joint photographing. Joint treatment must be thoroughly dry before proceeding with primer-sealer application and final decoration. Do not apply drywall joint compound to joints or fasteners that are to be tiled.
