GE Silicone I All Purpose caulk can withstand all weather conditions, and will remain permanently waterproof, flexible, and shrink-/crack-proof. Outdoor elements such as heat, sun (UV rays), and extreme cold can cause non-silicone to crack and crumble over time, leaving gaps for air and water to seep through. Those leaks can lead to water damage, mold growth, and higher energy bills.
Cut nozzle to obtain desired bead size and pierce inner foil seal. Using a caulking gun, apply sealant in a continuous operation applying a positive pressure adequate to properly fill and seal the seam, cavity, or joint. Smooth or tool the sealant into gap within 5–10 minutes of application. Tool or strike the sealant with a clean and dry gloved finger or caulk finishing tool, applying light pressure to spread the material against the joint surfaces to ensure a void-free application. Do not over tool or tool too thin. Doing so will have a negative impact on sealant integrity and performance. Sealant skins over in approximately 30 minutes, depending on humidity and temperature.
