Frequently Asked Questions
What is the best backerboard for tile?
For wet areas (showers, wet rooms), foam backer boards like Wedi or Kerdi-Board are the best choice — they are waterproof and lightweight. For floors and countertops, cement board (HardieBacker, Durock) provides excellent stability. For walls in dry areas (kitchen backsplash), cement board or fiber cement backer is appropriate.
Do I need backerboard for a kitchen backsplash?
A kitchen backsplash is a dry area that does not require cement board. Tile can be installed directly over properly primed drywall for a backsplash application. Cement board is still acceptable but unnecessary — the extra thickness can create issues with outlet depth and backsplash transitions.
