(1) When installed, the air, product and substrate temperatures should be equal to or higher than the manufacturer's recommended minimum application temperature. Although the typical minimum temperature range for your application is 40-50°F, consult your specific manufacturer for storage and handling in cold weather applications.
(2) The substrate must be free of any dust, dirt, oil, moisture or debris which may interfere with proper adhesion. Typically, the roof surface must be primed before the film is applied - as the SA board primer technology continues to evolve, check with the manufacturer for primer type, film rate and drying time requirements.
(3) The self-adhesive film should only be applied to acceptable substrates; consult an approved manufacturer for acceptable substrates.www.snpefilm.com
