Installation Instructions
- Apply to dry, clean surfaces that are free of grease and oils
- Cartridge applied with a caulk gun
- Coverage depends on size of the bead. 1/8" bead (343 ft), 1/4" bead (86 ft), 3/8" bead (38 ft), 1/2" bead (21 ft)
- Clean with water while the caulk is wet. Scrape off dried caulk with a putty knife.
