Tile Underlay Installation Process

From a standing position:

  • Prior to installation, complete all floor leveling & tile preparation procedures to a CSP-2 or greater.
  • Thoroughly clean & dry the structurally tile-appropriate substrate to be free from residue and dirt, including vacuuming & light damp mop if necessary.
  • Spray the DemoFlex Adhesive onto the floor substrate.
  • Wait approximately 20-40 minutes while the adhesive activates until it does not transfer to the skin. Use of fan recommended.
  • Thoroughly press the DemoFlex TMS Membrane into DemoFlex Adhesive using a hand roller, weighted roller or by hands & feet.
  • Bridge the seams of the TMS Membranes using DemoFlex Tape or sealer.
  • Apply the DemoFlex Tape or sealer around the perimeter of the installation area.
  • Spread mortar and set tile directly on top of DemoFlex Underlayment, using a quality, modified mortar & grout following industry standards. ‘Fast-set’ mortar is recommended for reduced curing time.

(Following the TCNA Handbook for proper tile installation)

The DemoFlex™ Systems consist of both the Spray Adhesive Can along with theTMS Membrane and Seam Tape together covering between 150-450 square feet depending on the membrane you choose. You will receive both the spray can, seam tape and membrane together. The membrane is meant to cover the entire surface of the floor installation and does not require any helpers like other membranes.
