Description

Lets you control the flow, so you can always “dial up” the perfect bead size. Turn it down for pinpoint precision. Crank it up for maximum coverage. Unlike other caulks that dry out Flex Caulk’s innovative hybrid polymer formula allows it to expand and contract, and stay completely flexible. Flex Caulk is 100% waterproof and weatherproof, as well as chemical and UV resistant. Plus, it’s solvent-free and virtually odorless. There’s no need to wait for surfaces to completely dry before caulking them. It even works underwater! Bathrooms, kitchens, sinks, showers, toilets, backsplashes, counter tops, baseboards, mouldings, pipes, skylights, windows, doors, autos, boats, and more. Flex Caulk is proudly made in America, using globally sourced products. Adjust the flow setting to the desired amount. Hold at a 45° angle, push trigger down, while moving the nozzle in an even motion. Remove excess caulk with a dry paper towel, do not use water. After use, secure the “Snap & Save” cap tightly on the nozzle.
