Fix through the tongue using stainless steel or hot-dipped galvanised nails or screws to prevent rust staining, and leave a small expansion gap at board ends. Western Red Cedar can be left unfinished to weather to a natural silver-grey or treated with a penetrating oil or UV-stable finish to maintain its warm reddish-brown tones - either way, ensure all cut ends are sealed on installation.\u003c\/p\u003e\u003ch2\u003eFAQ\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eDoes Western Red Cedar cladding need treating before installation?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eNo. Western Red Cedar has natural oils that give it good durability for above-ground external use without any pressure treatment.

Cedar contains tannic acids that react with plain steel and zinc-plated fixings, causing dark staining that bleeds onto the face of the board.
