Drafty windows, gaps around door frames, and worn-out caulk on siding can let in water, air and energy loss — and you shouldn't need a contractor to fix them. Gorilla 100% Silicone Window & Door is built so anyone can refresh problem areas with a smooth, confident bead. It forms a durable, 100% waterproof seal that holds up to sun, rain, and temperature swings, making it equally suited for fast touch-ups and full re-sealing projects.
- Cut nozzle at 45° angle to desired bead size. Completely puncture inner foil seal.
- All surfaces should be clean and free of dirt, grease, oil, and old sealant.
- Apply sealant in a steady bead, pushing the bead ahead of the nozzle.
- Smooth bead immediately after application, before a skin forms.
- Wipe off wet sealant immediately with a dry cloth.
Cure time: 24 hours. Cure time will increase with lower temperature, humidity and larger bead size.
