I bought a 75 year old log cabin home in northern Idaho. It was stained or oiled from 30s – 90s. Then somebody stuccoed it (must have been a heck of salesman). Then someone else painted over the stucco. As the newest owner, I scraped off everything loose, caulked all the cracks and primed and painted the entire structure. THEN I found your page. Will the breathability problem be helped by the age of the logs? Should I cut a slot on the underside of each log to let it respire? Help?
