Moisture- and mold-resistant gypsum panel for tile applications

  • Gypsum backer board for tile applications in high-moisture areas.
  • Acrylic-coated facer eliminates the need for a moisture barrier.
  • Ideally suited for a variety of interior applications.

Gold Bond® eXP® Tile Backer is manufactured with an enhanced moisture- and mold-resistant core encased in specially designed coated glass mat facers. The facer is then coated with a specially formulated acrylic coating, which provides superior protection against moisture and humidity. It provides an integral water barrier, eliminating the need for a separate water barrier. It is available in a regular core.

eXP Tile Backer is an acrylic-coated, moisture- and mold-resistant gypsum panel specially designed for use as a substrate for tile applications in high-moisture rooms, including showers, bathrooms, indoor swimming pools, laundry rooms, and kitchens.

Use eXP Tile Backer as a code-compliant substrate for tile and other finishes in both wet and non-wet areas, and areas of high humidity. It is ideally suited for interior walls and ceilings.

For an approved component in UL fire-rated designs use Gold Bond® eXP® Fire-Shield® Tile Backer (5/8” Type X).

APPLICATIONS:

  • Use in both wood- and metal-framed construction for interior wall and ceiling and countertop assemblies as a substrate for tile and other finishes.
  • Approved for use in high-moisture environments such as baths, showers, indoor pools, kitchens and laundry rooms.
