Tile Underlay Installation Process

From a standing position:

  • Prior to installation, complete all floor leveling & tile preparation procedures.
  • Thoroughly clean & dry the structurally tile-appropriate substrate to be free from residue and dirt, including vacuuming & damp mop if necessary.
  • Spray the DemoFlex Adhesive onto the existing substrate.
  • Wait approximately 20-40 minutes while the adhesive activates until it does not transfer to the skin.
  • Thoroughly press the DemoFlex Underlayment into DemoFlex Adhesive with hands & feet or tools like a 35lb roller.
  • It is recommended to tape or caulk the seams & perimeter of Underlayment.
  • 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 Release Spray Adhesive Can along with the Release Membrane and Seam Tape together covering between 100-300 square feet per roll 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 long roll, peel & stick membranes.
