Notable Features
Distinctive aromatic cedar scent; contains natural oils that provide weather resistance; can cause respiratory irritation or allergic reactions in sensitive individuals.
Finish Recommendations
Responds well to oil-based stains, transparent sealers, or paints. Water-based finishes work well if the wood's natural oils are cleaned with a solvent first.
Identification Confidence
High; the distinctive reddish hue, coarse texture, and growth ring patterns are classic indicators of Western Red Cedar dimensional lumber.
