Can I Use Only a Clear Finish on My Log Home Exterior?

 

Ask the Expert: Perma-Chink Systems Question: Can I Use Only a Clear Finish on My Log Home Exterior? In this installment of Ask the Expert, the pros at Perma-Chink Systems, Inc. explain the realities of clear finishes for log homes. The raw beauty of freshly milled logs, with their organic warmth and graceful grain patterns, appeals to many homeowners. Others are smitten by the silvery patina of aged wood and dream of having this aesthetic for their own log home.   This raises a natural question: can a clear finish preserve the look of bare logs or encourage natural aging while still protecting the structure? While a clear finish has some benefits, it’s rarely the best choice for achieving a consistent, long-term aesthetic.    The Benefits of Clear Finishes   A clear finish can feel like the purest expression of the wood, allowing the natural tone and texture of the wood to remain fully visible. Expectations, however, do not match reality. Log cabins last for decades — sometimes centuries — and over time, a clear finish neither preserves a fresh wood appearance nor is it ideal for natural aging.    A clear finish on bare logs has some merit. Perma-Chink’s Lifeline Advance accomplishes two important tasks. It brings enhanced beauty and luster to the wood without changing its appearance, and its breathable film allows moisture to escape while simultaneously preventing water intrusion. Water repelled and existing moisture inside the log is not trapped under the finish. This dual approach to water protection prevents log rot and decay.
