My research and inquiries have allowed me to narrow down my options to what the experts recommend. And I would like to share with you the fruits of my research and inquiries.
The cedarwood, especially the Western Red Cedar, is a widely used wood species for outdoors. It is a tough wood characterized by its anti-microbial properties. Hence, it is a perfect choice for outdoor furniture. It might be a resilient wood, but you still need to provide primary care to preserve its natural beauty. Thus, giving western red cedar wood the best exterior finish would further extend its longevity. It will also protect the wood from turning gray.
Which Finish Should You Choose?
You got two options when treating cedar. You can either stain or paint it. Moreover, you can also leave it untreated. Your choice, however, boils down to your preference. It will also depend on the level of protection required by your project.
It will help balance the protection you would like to provide your cedar and the appearance you would like to render it. If you want your cedar to sport a weathered appearance, you can use a transparent oil finish. If you are desirous of protecting your cedar from UV lights and other harsh elements, you should use an opaque finish.
As a caveat, the amount of rain and sunlight that affects the cedar will shorten the longevity of the finish that you have applied. Hence, you should use an oil-based stain if you think the wood will be constantly exposed to these harsh elements.
Besides, your choice will depend on the maintenance level you intend to provide your cedar. If you don’t plan to reapply refinishing on your project within a year, you might as well choose a finish that doesn’t require immediate refinishing within a year or two.
