My wife and I are building a log home in North Central Ontario (Algonquin area). The logs are hand hewn Eastern white pine, 8” thick, and vary from 14” to 18” in depth. The chink gaps are filled with expanding foam, and will be finished with Permachink. I plan to build a false wall inside the log wall in the kitchen area, from which to hang the kitchen cabinets. This false wall will ”float” allowing the cabinets to be securely fastened but allowing the logs to behind them to move as require
The wall in the kitchen is the correct way to do it. The expandable foam will be a problem with the Perma Chink. The foam gives off a gas that will cause the chinking to bubble. It should be removed as much as possible and then use a closed cell foam for a backer under the chinking.
