Atlas® WeatherMaster® PolySeal™ SE Peel & Stick SBS Reinforced Underlayment

WeatherMaster® PolySeal™ SE

WeatherMaster® PolySeal™ SE is a durable, self-adhering modified composite underlayment, specifically designed to withstand the rigors of all roofing applications. It can also be used as flashing tape to provide a secondary water barrier. WeatherMaster® PolySeal™ SE is an excellent underlayment for metal roofs.

The tough, slip-resistant poly fabric surface provides a rugged barrier to physical damage, UV degradation, weather, and moisture. The unique adhesive layer offers the application benefits of cold temperature adhesion and exceptional thermal stability under high heat.

WeatherMaster® PolySeal™ SE prevents moisture entry into structures by sealing uniformly to the substrate and around nail penetrations. Since WeatherMaster® PolySeal™ SE is self-adhering and cold applied, no special adhesives, heat, or equipment is necessary when properly installed.
