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 cladding 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 cladding 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.
