LEXEL Waterproofing Sealant

Lexel® is the “duct tape” of all caulks. Super-elastic. Superior adhesion. Paintable. It seals around anything: tubs and shower stalls, sinks and counter tops, window frames and door frames, PVC and metal pipes. Apply to wet or dry surfaces, indoors and outdoors. It’s tough and can handle up to 400% joint movement. It’s scrubbable. It sticks to just about anything. Lexel clear caulk is 19 times clearer than silicone and won’t yellow or cloud up over time. Lexel won’t let you down.
