Cement board panels – sometimes referred to as tile backerboard – are wallboard sheets made with cement and other water-resistant materials. They have now become the standard for use in high-humidity areas, especially behind ceramic tiles, where moisture intrusion can be an issue.

FibaTape® Cement Board Tape is alkali-resistant and the only tape that should be used for cement applications with dry or thin-set mortar. This tape is made from the same vinyl-coated fabric that is embedded in the face of some cement boards to give the board added strength and crack resistance.

Other benefits include:

  • Alkali-resistant for enhanced long-term performance in cement applications
  • Works in dry and thin-set mortars
  • Self-adhesive for easy application
  • Ideal for indoor and outdoor use
  • Heavy fiberglass yarn increases joint strength and structural integrity
  • Resists mold and mildew
  • Ideal for use in bathrooms and kitchens


  • Cement board joints
  • Tile backerboard
