509 ALL-WEATHER MODIFIED MASTIC is the go-to choice for professional roofers demanding a heavy-duty, commercial-grade mastic capable of performing in challenging conditions and on specific membrane types. This rubber modified compound is designed for application in all weather, wet or dry, and possesses the remarkable ability to bond underwater for both temporary and permanent repairs. Its formulation, fortified with Power Gel Technology, ensures it remains highly resilient and durable through all seasons, resisting cracking even under high heat conditions.
509 is specifically engineered for use with modified bitumen membranes (SBS) and conventional Built-Up Roofing (BUR) membranes, particularly in areas where substrate movement is expected to occur. Its modified properties provide excellent adhesion, elongation, and recovery characteristics, crucial for sealing seams and repairs on these systems. This mastic offers easy spreading and application, features anti-sag properties, and eliminates the burn hazards associated with hot kettles and propane torches, making it ideal for use where open flames are prohibited. 509 is excellent for repairs and seams on SBS Asphalt Modified Roll Roofing Sheets and can be used on flashings, around skylights, gutters, crevices, and other penetrations on recommended substrates including BUR, SHINGLE, TILE, MOD BIT, CONCRETE & METAL. Please note, it is crucial NOT to use 509 on APP, TPO, EPDM, or PVC membranes. Meeting ASTM D 4586 and ASTM D 3409 standards and holding Miami-Dade NOA compliance, 509 ALL-WEATHER MODIFIED MASTIC from A1A Wholesale Supply offers a dependable, high-performance solution for your commercial and modified bitumen roofing needs nationwide.
