Galley and kitchen carcasses with sealed edges

Working & finishing tips

First, acclimatise boards to the room. Next, pre-seal all edges (particularly cut edges) with a suitable sealer or varnish. Then fix at the recommended centres and leave small expansion gaps at walls and corners. Finally, apply a water-resistant finish; in shower or splash zones, use an appropriate membrane or liner.
