Applying DuPont™ 25 Year Painter’s Caulk

Follow these simple instructions for applying the product.

Applying DuPont™ Silicone Sealants is simple and all of the products easily clean up with mineral spirits. DuPont™ Paintable Premier Silicone is available in a cartridge which 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. 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. 

Application:

  • Test paint for compatibility prior to caulking.
  • 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.
  • 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 soap and water
  • Cured bead should be between 1/8” and ½” wide.
  • Allow 4 to 6 hours before applying paint
  • Coverage: 50 linear feet for a 3/16” bead (9.5 oz cartridge)
