No, the KR dam has a “patented” recessed channel design that eliminates to need for additional glue or adhesive reinforcement of the edges. The recessed channel with automotive grade 3M tape pulls the dam tight to the shower surface along the perimeter of the dam providing a integral flexible friction seal similar to a car or window seal that that is easy to clean and maintain. This feature also limits water exposure to the tape, so the tape maintains a long-lasting bond.
