If you plan to mount bathroom fittings, a washbasin, faucet, wall-mounted toilet or other bathroom furniture on the panel, you need to install, for example, a 0.5-inch thick sheet of plywood behind it. You can, of course, attach the decor to studs behind the wall. 

Fibo Seal is specially developed for our panels and is ETAG 022 approved. Fibo Seal is also supplied in the same colors as the joints on the panels. Do not use silicone, only MS polymer sealant approved according to SINTEF TG 2289.

You should use about 14 screws per sheet (installed at approx. 8-inch intervals) and approx. 4-6 screws per inner corner. The rule of thumb is one package of screws for ten 24″ panels. The rule of thumb is one tube of Fibo Seal for 6 panels.
