Fire resistant gypsum plasterboard

The board has a non-combustible gypsum core, enhanced with glass fibers for protection against fire and the passage of heat. It is covered with blue paper facings on the front, back, and long edges.

The special-bonding blue veneer facing paper creates an optimum plaster "working" rate and increases plaster adhesion. The board will accommodate up to two veneer plaster finish coats.
Firecheck Plasterbase is designed for use in applications that require direct mechanical attachment to wood or metal framing. For best plaster-working and adhesion properties, the veneer plaster should be applied as soon as possible after board installation.

To ensure optimum Type X fire-resistance performance from this board, follow recommended installation procedures.

Note: Firecheck Plasterbase is suitable for interior applications only, and should not be used where temperatures exceed 125 degrees F for extended periods or in areas of extreme humidity. Likewise, the board should be protected from exposure to adverse conditions during storage and construction. The special facing paper is unsuitable as a base for adhesive applications such as tile and paint.
