Big Stretch is a high-quality, professional-grade elastomeric sealant that is specifically designed for use in a wide range of residential building and remodeling applications. It’s a high-performance sealant that offers superior flexibility, elasticity, adhesion, and ease of use, making it an excellent choice for professionals and DIY enthusiasts!
Homes move. Window frames move away from the siding or doors shift against the brick. This movement happens as the home settles as well as with temperature changes and even wind. If movement causes a sealant to crack, you can lose the air or moisture barrier in your home. That’s why you need Big Stretch®. With powerful adhesion and extreme elasticity, it will stick, twist, bend, compress, and stretch — 530% maximum stretch — to handle most any movement your home can dish out, all without cracking.
Application: Natural shrinkage will give the joint a concave appearance; multiple applications may be needed to fill the joint flat. If dirt or oils are present on the substrate, wash with any household
cleaner, rinse to remove and allow to thoroughly dry. Remove any old caulk, especially silicone and all silicone residue. Use a silicone remover. Insert backer rod into joints deeper than 1/2” to provide for proper sealant depth and a stronger, longer lasting seal. Choose bead size and cut the nozzle. Puncture the inner seal. Gun Big Stretch into the joint. Tool for a smoother bead using a damp foam or paint brush with a light, skimming touch, or use a beading tool.
Dry Time: Full cure 4-5 days (depending on temperature and humidity) Paintable: 4 hours with exterior painting, 1-2 days with interior paints, 1 week with oil-based paints.
Application Range: 40° to 120°F (4° to 49° C) surface temperature, Service Range: -30° to 250°F (-34° to 121°C) Lower temperatures and higher humidity will slow cure time. Allow 1-3 days curing before exposure to direct rainfall. Use plastic sheeting with good airflow underneath to protect the product if rain is expected sooner.
