100% waterproof and leakproof. Hygienic, easy to fit and easy to clean. Creating a 100% waterproof and leakproof shower starts with your choice of Aquaclad wall panels. But you\'re not done there. You also need exterior corners to cover panel edges and keep water out. That is the purpose of genuine Aquaclad exterior corner pieces. These particular pieces are black. Aquaclad exterior corners are glued on where two Aquaclad panels meet to create an exterior corner. When you purchase them as part of a 2- or 3-wall kit, your adhesive is included. You will need to buy adhesive separately if you are doing a customised install without a kit. Note that installation is as easy as fitting wall panels and gluing the corner to both surfaces where they meet. Once in place, you will have a beautiful finished edge that keeps water out and is not prone to mould. You keep the corner pieces clean the same way you clean Aquaclad panels: by wiping them with a damp cloth every now and again. As always, you get our 10-year guarantee with these exterior corner pieces. If you still have questions, feel free to contact us. First time buying wall cladding? Learn more and compare products here.
