100% waterproof and leakproof. Hygienic, easy to fit and easy to clean. When installing white Aquaboard laminate shower panels, there is no better way to finish internal 90° angles than these tough, hard wearing 2-piece corner joints. Installing corner joints is a far better option than simply applying sealant to exposed edges. Aquaboard corner pieces have been specifically designed to create a solid corner joint that is both waterproof and leakproof. The goal is accomplished thanks to a unique two-piece design with integrated notches that allow 10 mm panels to slide right in. When installed with adhesive and sealant, edges are completely covered. Water is kept out, too. Installation is as easy as affixing the back piece of the kit to the wall first. Next, each of the two panels can be coated with adhesive, slid into their appropriate notches, and attached to the wall. Inserting the outer piece of the corner into the remaining slot finishes the joint and creates a watertight seal. We are proud to say that Aquaboard laminate shower panels are scratch resistant and durable. They are so tough that we back them up with a 10-year guarantee. First time buying wall cladding?
