This summer we took on a log home exterior – a different kind of project for us but we enjoyed it and learned some important tips on log home maintenance in Montana.
Log homes have special needs because their structure is exposed to the elements – sun, wind, water, extreme temperature changes and even bugs. Ultraviolet exposure from the sun is the primary cause of log rot in places like Choteau, Montana, where it’s dry and sunny much of the time.
We found that all of these elements can be combated with the right kind of log finish. The best log finish will offer UV inhibitors, flexibility, breathability (some, but not too much), insect inhibitors and of course protection from rain and snow. We also learned that finishes with darker pigments offer better UV protection. If you own a log house, put this kind of armor on it.
We used a log and siding finish by Sikkens that we believe is outstanding. We’ll watch it perform over the next few years with great interest.
We consulted an excellent book for this project that log home owners should have in their libraries: The Log Home Maintenance Guide by Gary Schroeder.
