• 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.

Use Gold Bond® eXP® Tile Backer as a substrate for tile applications in high moisture areas, including showers, bathrooms, indoor swimming pools, laundry rooms, and kitchens. It is also a code-compliant substrate for tile and other finishes in both wet and non-wet areas, areas of high humidity, and fire-rated assemblies (5/8” Type X). It is ideally suited for a variety of interior applications.
