Surface Preparation

The area to be sealed should be thoroughly cleaned before caulking any joint, gap or crack. Surfaces must be clean 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 when caulk, surface and air temperatures will remain above 40°F. Do not apply on surfaces that are above 120°F.


  • Clean surface to be caulked
  • For gaps greater than 1/2" deep, use a backer rod
  • Insert tube into caulk gun
  • Cut nozzle at a 45° angle and with the desired opening size
  • Puncture inner foil seal
  • While slowly squeezing the caulk gun trigger, gently push the nozzle along the gap to be sealed. Make sure sealant is in contact with both sides of gap.
  • Smooth applied bead with a moist cloth
  • Clean tools with soap and water
  • Allow 4 to 6 hours before applying paint
  • Cured bead should be between 1/8' to 1/2" wide.
  • Allow 24 hours before exposing to a wet or damp environment.

Not intended for areas that will be painted or submerged in water.
