Using Window & Door Choice Silicone
Follow these simple instructions for caulking windows, doors and siding areas. Applying DuPont™ silicone sealants is simple and all of the products easily clean up with mineral spirits. DuPont™ Window & Door Choice Silicone is packaged in a cartridge which requires a caulk gun to apply product.
The area must be thoroughly cleaned before caulking any joint, gap or crack. Surfaces to be caulked must be dry and free of all dirt, dust, oil, mildew, loose paint and old caulk. Use masking tape to prevent sealant from sticking to adjoining areas. Remove tape immediately after sealant has been tooled. Only apply sealant when surface and air temperatures will remain above 40°F. Do not apply on surfaces that are above 100°F.
• Clean surface to be caulked.
• For gaps greater than 1/2″ deep, use a backer rod.
• Insert caulk tube into the caulk gun.
• Cut the dispensing nozzle at a 45° angle.
• Puncture inner foil seal.
• While slowly squeezing the caulk gun trigger, gently push the sealant nozzle along the gap to be sealed. Ensure complete contact is made on both surfaces being sealed.
• Smooth applied bead with a moist cloth or finishing tool.
• Clean tools with mineral spirits.
• Cured bead should be between 1/8″ and ½″ wide.
• Allow 12 hours curing time before exposing to a wet or damp environment.

Frequently Asked Questions:
• What is Home Sealing?
Home Sealing is a process recommended by the EPA ENERGY STAR® program to increase the energy efficiency of your home by improving the effectiveness of the building envelope. Sealing air leaks helps to enhance the performance of your insulation and may help to cut up to 20% of your energy bill, according to the EPA. Visit www.energystar.gov/index.cfmc=home_sealing.hm_improvement_sealing for more information.
• What is a home envelope?
The exterior of your home is also called the ″envelope″ or shell. The insulation, outer walls, ceiling, doors, windows and floors all work together to control airflow in and out of the structure, repel moisture, and prevent heat from being lost or gained inside your home. A high-performance envelope helps maintain a consistent interior temperature even under extremely hot or cold conditions. The goal of Home Sealing is to help improve the home envelope to make homes more comfortable and energy-efficient.
• Is Home Sealing something I can do myself?
Absolutely! You can seal holes, weather-strip doors, caulk around gaps in pipes and wires, floors, basements and crawl spaces. Remember, it's important to always air-seal before adding insulation. ENERGY STAR® has a written Do-It-Yourself Guide to help with the process of Home Sealing, which can be downloaded by going to http://www.energystar.gov/ia/partners/publications/pubdocs/Seal_and_Insulate.pdf.
