Appearance:Cedar’s rich grain and texture offer a timeless
complement to any architectural design, from turn-of-the-century to
contemporary. Its natural colour gradations range from pale straw tones
to deepest chocolate hues. It will weather to a silver grey colour over
time.
Finishing: Paints, stains, varnishes, oils and waxes all work well.
While Cedar can be left unfinished for a rustic wheathered look, the
use of a quality finish can enhance both its good looks and its natural
characteristics. Wetern Red Cedar accepts a wide range of stains in
your choice of tinted transparent finishes for a natural effect, or
lightly pigmented semi-transparent finishes. Consider a
coating that offers good fungicide and ultraviolet shielding properties
as well as additional preservatives to protect your project's youthful
complexion. Varnishes and other film-forming coatings which can crack
and peel are not recommended for use on Cedar.
