APPLICATION INSTRUCTIONS

GLUE-DOWN INSTALLATION INSTRUCTIONS - 3-EASY STEPS - TROWEL APPLIED
1. Cut underlayment to length and lay loosely over the area to be installed.
2. Pull the loose laid material back at least half the length of the roll. Using the recommended trowel, apply approved adhesive to the subfloor. Allow approved  adhesive to flash (no flash time needed for MS polymer or urethane adhesives) for recommended time prior to placing underlayment into adhesive. Upon placing underlayment into the adhesive, roll both ways with a 100 lb roller. Repeat the installation for the other half of the subfloor, insuring all joints are butted together tightly.
3. Allow adhesive to set prior to proceeding to flooring installation. See adhesive product label for additional flashtime information. It is highly recommended to allow at least 18 hours prior to installation of the flooring.
Notes: Refer to flooring manufacturer and ANSI or TCNA handbook for ceramic tile and stone installations and thinset recommendations.

Always check with the flooring manufacturer for installation recommendations.

For glue down applications, please consult flooring adhesive recommendation for trowel and coverage.


FLOATING FLOOR INSTALLATION - 6 EASY STEPS
1. Check for nails
2. Sweep or damp mop
3. Roll out 1 width of membrane
4. Cut roll at the wall
5. Install flooring planks
6. Roll out next width

Repeat steps 3 to 6 until floor is completed

Never mechanically fasten the isolation barrier with screws, nails or staples as this will severely diminish the acoustical values of the barrier.
