Western Red Cedar

ITI NZ
Visit Website

Western red cedar heartwood shows variations in colour when fresh from dark brown to pink colour, maturing to a reddish-brown and, in time to silver-grey when weathered. The sapwood is a paler colour. Straight grained and rather coarse texture, it has a very low shrinkage factor. Also, machines and stains very well

WR Cedar is easily worked. Since WR Cedar is very soft there is a risk when dressing it that the cutters may compress the softer earlywood which will later recover to produce a ridged surface. Thus sharp cutters are required. Sanding dust can be very irritant to the breathing passages so a well-ventilated workshop is essential. 

WR Cedar takes glue, stain and paints well.
