DuPont™ AIRTITE® Siliconized Acrylic Caulk Application

Follow these simple instructions for weatherization sealant application.

Applying weatherization sealant from DuPont is simple, and the products easily clean up with just soap and water. DuPont™ AIRTITE® Siliconized Acrylic Caulk with Weather-Tight Seal technology is available in both squeeze tubes and cartridge packaging that requires a caulk gun to apply.


Surface Preparation: 

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. Only apply when caulk, surface and air temperatures will remain above 40°F. Do not apply on surfaces that are above 120°F.  Do not apply on exterior surfaces when rain is immediately expected.

Application:

• 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 45° angle.
• 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.
• Clean tools with soap and water.
• Allow 4 to 6 hours curing time before applying paint.
• Cured bead should be between 1/8” and ½” wide.

   environment.

Frequently Asked Questions:

Why is caulking or Home Sealing important?
Reducing air leaks by caulking or sealing is recommended by the EPA ENERGY STAR® program to increase the energy efficiency of your home by improving the envelope. Sealing air leaks allows full performance of your insulation and can cut up to 20% of your energy bill according to the EPA.
Visit www.energystar.gov/index.cfm?c=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 temperature even under extremely hot or cold conditions. The goal of Home Sealing is to improve the home envelope, to make homes more comfortable and energy efficient.

Is Home Sealing something I can do myself?
Absolutely! You can seal up holes, weather-strip doors, caulk around gaps in pipes and wire, floors, basements, and crawl spaces. Remember, it’s important to 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
