Plasterbase® Type X drywall

Continental Plasterbase is a base layer gypsum board for interior veneer, plaster-finished wall and ceiling applications that require fire resistance.

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.

Identification: Dark blue face paper clearly distinguishes Firecheck Plasterbase Type X from regular drywall.

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. It is used on:

  • Interior walls
  • Interior ceilings

Ease of Installation:
Fast installation similar to regular drywall.

Compatibility: Provides a strong bonding surface for gypsum veneer plasters that meet ASTM C 587.

Fire Resistance: Firecheck Plasterbase Type X is formulated to perform in accordance with ASTM C 1396, Section 10 and C 588, Type X and is UL labeled (Type LGFC6A).
