backerboards
Backerboards are substrate panels used in construction to provide a stable, non-deformable surface for tile, stone, or plaster, especially in moisture-prone areas. They are typically cementitious or fiber-reinforced cement panels, though gypsum-based variants exist for interior applications where moisture is less of a concern. Backerboards resist rot, warp, and mold better than standard drywall and help prevent tile failures by providing a solid base.
Common types include cement backer boards, fiber cement backer boards, and gypsum-based backer boards designed for
In wet areas such as showers, tub surrounds, and bathroom walls, backerboards are preferred because they offer
Advantages of backerboards include high moisture resistance, dimensional stability, and strong support for heavy tile, which
Limitations include higher weight and cutting difficulty compared with drywall, higher cost, and the need for
