100% waterproof and leakproof. Hygienic, easy to fit and easy to clean. No aquaboard installation is complete until the outside edges are capped with a piece of trim. We offer a variety of trim options, including aquaboard\'s black edge trim. This piece works seamlessly with any 10 mm board in either the aquaboard laminate or PVC range. Outside edges of aquaboard wall panels are finished with trim for two reasons. First is aesthetic appearance. A piece of black edge trim makes for a beautiful finish you just cannot get from caulk. Second is the need to create a watertight seal. A correctly installed aquaboard shower panel is 100% waterproof and leakproof. To accomplish that however, you need a proper piece of edge trim that has been correctly installed and sealed with our silicone sealant. Done right, the trim keeps out water and creates an aesthetically pleasing finish. You can purchase black edge trim for use in your own custom installation or to replace the trim that comes in an aquaboard shower kit. Either way, you get a product with a 10-year guarantee and the full support of our customer service. First time buying wall cladding? Learn more and compare products here.
