Superior Bond For Superior Protection
Polyglass roofing and waterproofing sealants provide a strong lap seal when used with Polyglass® Polystick® Underlayments.
PG 500 Modified Cement
Polyglass® Polystick® roof underlayment membranes must be installed to ensure full contact with approved substrates. Over-fabric and over-granule laps should have a 6-inch wide, uniform layer of Polyglass PG 500 Modified Cement applied in between the application of the lap for proper adhesion.
PG 500 is required for all Polyglass underlayment lap seal applications to comply with product warranty coverage requirements. When installed properly to meet manufacturer installation guidelines, the roofing system can achieve a 30-year guarantee.
