Homes move. Big Stretch provides the adhesion and flexibility to handle the movement. Big Stretch is a 100% high-performance acrylic latex caulk with powerful adhesion and elasticity. Big Stretch will stretch and compress to absorb just about any movement a home can dish out. It spans gaps up to 2-inches wide and stretches up to 500% of the original joint size without cracking. Big Stretch is perfect for many interior and exterior applications, including windows, doors, siding, vents, soffits, eaves, and baseboards. It is also good for crown molding and sound proofing interior walls. Big Stretch should not be used or specified in areas of water submersion, where frequent or prolonged puddling occurs, or in areas of high foot or vehicle traffic (i.e. tubs, showers, sidewalks, driveways, highways, and patios). Not for use on roofs, where prolonged dampness or possible submersion may inhibit curing.
