100% waterproof and leakproof. Hygienic, easy to fit and easy to clean. The Aquaboard a cream-coloured internal corner is a two-piece corner intended for use with 10 mm Aquaboard panels. Installing it finishes off two panels where they meet at a 90° angle. Your finished corner will look professional without sacrificing hygiene or cleanliness. Once installed, you will be left with a corner joint that is 100% waterproof and leakproof. Best of all, installation is fairly straightforward. With moderate DIY skills, you and an assistant can easily put both Aquaboard panels and corner pieces in place. The corner piece itself is mounted directly onto the wall. The back of the piece has two integrated slots that accept the leading edges of Aquaboard panels. Once those panels are attached to the wall, just a small gap between them remains. That gap is filled by the outer piece of the corner joint. Internal corner pieces are just as durable and hard wearing as Aquaboard panels. They are scratch resistant, easy to keep clean, and equally capable of keeping out moisture. Corners are included in our kits, or you can buy them separately. First time buying wall cladding?
