Code compliant tile backer application
- Gypsum backer board for tile applications in high-moisture areas.
- Acrylic-coated facer eliminates the need for a moisture barrier.
- Type X core is fire resistant and is an approved component in UL fire-rated designs.
Gold Bond® eXP® Fire-Shield® 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 Type X core.
eXP Fire-Shield 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 Fire-Shield Tile Backer as a code-compliant substrate for tile and other finishes in both wet and non-wet areas, areas of high humidity and fire-rated assemblies. It is ideally suited for interior walls and ceilings.
For a 1/2" regular core product that is not used in UL fire rated designs use Gold Bond® eXP® Tile Backer.
Check the Fire and Safety Information for a more complete explanation of how fire resistance ratings work.
