the membrane and to the substrate. This gives a net coverage rate of 60 square feet per gallon (i.e. approximately 1.7 gallons per 100 square feet). The coverage rate will vary depending upon the porosity of the substrate.

6. Do not apply adhesive to the membrane where hot-air welding will be performed.

7. Allow adhesive to dry (approximately 5-10 minutes) until it does not stick or form strings when a dry finger is pushed into it and removed. The dry time will vary due to ambient air conditions.

8. Open time prior to mating the membrane to the surface may extend up to 60 minutes depending on the ambient air condit ion s. Howeve r, the installer is urged to apply the membrane to the substrate as soon as the adhesive is ready.

9. Mate the adhesive coated membrane to the adhesive coated substrate slowly and evenly to avoid trapping air and to minimize wrinkles.

10.Immediately broom or roll the membrane into the adhesive to ensure proper bonding.
