Lexel is the duct tape of all caulks. It is super-elastic, paintable, and has superior adhesion. It seals around 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 is tough and can handle up to 400%joint movement. It is scrubbable and sticks to just about anything. Lexel clear caulk is 19 times clearer than silicone without yellowing or clouding up over time.
