Do not attach accessories like coat hooks, light fittings, mirrors, etc. directly to the tiles. Drill holes through the tiles and use suitable anchors to attach the accessories securely into the framing behind.
For installation in a shower area, around a bath or other very damp places, a bead of silicone sealant must be provided in the tongue and groove connection between the tiles themselves and between the tiles and support trims to ensure a completely waterproof joint. Also apply a silicon bead between the tile and the edge of the shower or the bath.
For edge treatment, you can use a 5/16-inch aluminum flooring edge trim for a professional edge look. These aluminum trims will need to be installed prior to, or at the same time as, installing the tiles.
color-matching caulk or clear silicone adhesive can be used to finish outside edges and/or inside corners.
