K-Board Waterproof Backer Board Kit 6 Sheets




Waterproof Shower Backer Board

The integrity of your tile is only as good as its foundation. KBRS Backer Board provides a strong, lightweight, waterproof, and vapor-resistant tile base for wet areas. It is an XPS foam panel manufactured with a waterproof proprietary blend of synthetic polymer mortar and an alkali resistant fiber mesh. This gives it a highly rigid structure and exceptional bonding strength.

The backer board installation kit includes:

  • Six Sheets of KBRS Board backer board (3' x 5' x 1/2" sheets)
  • Four tubes of KBRS ShowerSeal® Polyurethane Sealant (10.1 oz. each)
  • 200 Washers and 200 Screws

Note that this kit provides enough backer board to cover 90 square feet. Additional materials may be necessary for larger shower installations.
