The Blanke PERMAT is an innovative uncoupling tile underlayment that offers added support to wood substrates thereby reducing deflection and provides greater compression and tensile strength than plastic tile underlayment roll products. The Blanke PERMAT is stable to walk on during installation and does not require additional curing time when installing porcelain with latex modified thinset.

Properties

  • Strengthens wood substrates
  • Reduces vertical subfloor movement (deflection)

  • Superior tensile strength
  • Crack isolation properties (uncoupling)
  • Superior resistance to delamination during installation
  • No extended cure time for latex modified thinset mortars under porcelain tile
  • Lightweight; easy to install
  • Self-seaming panels prevent substrate movement stress from transmitting to tiled surface
  • 1/8" thick
  • Permanent Support of high quality floorings - ex: stone, marble
  • Assures HIGHEST protection for your construction project
