One-Part Pourable Sealer

WeatherBond/Carlisle One-Part Pourable Sealer is a single-component, moisture-curing, elastomeric polyether sealant that is compatible with WeatherBond RBR EPDM membranes. The material is designed to provide a flexible, durable and long-lasting seal around hard-to-flash penetrations in EPDM Roofing Systems.

Coverage Rate: .23 gallons per 6" pocket

One-Part Pourable Sealer provides rapid skin time when exposed to atmospheric moisture forming a waterproof rubber surface in less than one (1) hour. Moisture curing continues, until a two (2)–inch deep solid rubber seal encases the penetration. Complete cure time will vary depending on relative humidity and temperature. The sealant’s one-part, pourable consistency allows for quick pocket fi lling without mixing. WeatherBond’s Multi-Purpose or Low-VOC EPDM Primer must be applied to all EPDM surfaces, including cured membrane and uncured flashing, that will be in contact with One-Part Pourable Sealer. Primer should not be applied to the plastic (HDPE) strip that is part of the WeatherBond Pourable Sealer Pocket. Unused sealant remaining in a pouch will remain useable up to 30 days if pouch is resealed with original cap.
