About Tile Backer Board


Tile backer board, also referred to as wall board, foam board, or building panels, is used as a substrate behind tile installations to provide a stable, moisture-resistant surface. These panels are installed over wall framing, subfloors, or countertops prior to tile installation to create a reliable base for thinset mortar and tile assemblies.


Tile backer boards are commonly used in bathrooms, kitchens, showers, and other wet or high-moisture environments where traditional drywall or plywood may not be suitable.

Types of Tile Backer Board

  • Cement Backer Board: Dense cement-based panels designed for strength and moisture resistance.
  • Foam Backer Board: Lightweight panels with waterproof cores.
  • Fiber-Cement Board: Cement boards reinforced with fibers for added strength.
  • Building Panels: Multi-purpose panels designed for tile substrates and waterproofing systems.

How to Choose Tile Backer Board

  • Application Area: Walls, floors, countertops, or wet areas.
  • Moisture Exposure: Select waterproof or moisture-resistant panels for wet zones.
  • Panel Thickness: Choose appropriate thickness based on framing and load requirements.
  • System Compatibility: Confirm compatibility with thinset mortars and waterproofing membranes.

Common Applications


Tile backer boards are used behind tile in showers, tub surrounds, bathroom walls, kitchen backsplashes, floors, countertops, and other tiled surfaces in residential and commercial installations.

Why Use Tile Backer Board


Tile backer boards provide dimensional stability, moisture resistance, and a reliable bonding surface. Using a proper backer board helps reduce movement, support tile adhesion, and contribute to long-term installation performance.
