High-Performance Elastomeric Sealant
Sashco Big Stretch is a water-based acrylic elastomeric caulk designed to seal doors, windows, siding and mortar joints. It spans gaps up to 2 In. wide and adheres to most interior or exterior surfaces. The 10.5 Oz. cartridge delivers 26 LFT per 1/4 In. bead for efficient coverage.
Suitable For Flexible Sealing Tasks
This sealant suits projects requiring permanent flexibility and moisture resistance across a service range of -30 F to 250 F. It is paintable and stainable after 4 Hrs. Builders needing a heat-resistant formula or a smaller gap-filling capacity should look at alternative products.
Sustained Performance Under Load
The formulation remains permanently flexible through seasonal movement without cracking. It resists mold and mildew growth over a lifetime of exposure. Tools clean with water while the product is wet, and the seal maintains adhesion through repeated expansion and contraction cycles.
