What is approximate lineal foot coverage of one tube. Just need some ballpark idea

Thank you for the question. Loctite PL Premium Polyurethane Construction Adhesive is not measured in terms of square footage, but instead linear feet based on different size extruded round beads. Not knowing the details of your project, it is not possible to determine square footage. For a 10 fl. oz. cartridge, a ¼” (6 mm) bead extrudes approximately 30.6 ft. (935 m) and a 3/8” (9.5 mm) bead extrudes approximately 13.6 ft. (4.1 m).
