The 18:1 mechanical advantage provides 18 lbs. of application pressure for each lb. of force applied to the trigger handle, perfect for applying high viscosity caulks and adhesives.

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 100°F.


  • Test paint for compatibility prior to caulking
  • 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
  • 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 or finishing tool
  • 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.

Not intended for areas that will be submerged in water.
