My log home has 3/4 logs with 2×6 framing. I have these cracks. in the winter they fill with snow melting then freeze and check more. When that happens it sounds like a gun shot. Can I seal these with stacker caulk? Also where can I get minwood filler putty?
Be aware that if you file all of the checks that they will need constant attention. When you fill the check with caulk, the caulk over time will dry out and break lose from the wood, leaving a hair line crack that allows water to seep down in behind the caulk. Since the opening is filled it cannot dry out fast enough and will start to cause rot. We recommend applying a borate mixture into the checks once a year. Take a squeeze bottle with a small nozzle and squirt the mixture down and along each major check.
