Preparation & Application

All surfaces to be caulked must be dry, clean and free from mildew, loose paint or coatings, oil, grease, rust, dirt, and other foreign matter.

Cut spout at an angle to desired bead size and load into a standard caulking gun. Karnak 44 Klear Seal Caulk should be applied with even pressure directly over the crack or joint. Before the caulk begins to skin over, tool with even pressure directly over the crack or joint. Before the caulk begins to skin over, tool  with even pressure to create a positive seal with the substrate. Excess caulk should be wiped away with a damp cloth before skinning over. An application  rate of a ¼” x ¼” bead of caulk will yield approximately 25 lin. ft. per 10.1 oz caulking cartridge. Coverage rate may vary depending on desired thickness and surface to be caulked. Apply when temperatures of the caulk, substrate and ambient air are 40ºF and rising. Karnak 44 Klear Seal Caulk dries quickly to the touch in about 1 hour and may be painted over after 4-6 hours dry time (depending on temperature and humidity).
