Gaps between log courses are a common problem in log homes. As moisture evaporates slowly from logs, the logs shrink over time and leave gaps. Drafts can result from these gaps, which can reduce energy efficiency. These gaps allow moisture to accumulate between logs, increasing the risk of decay. They also provide entry points for wood boring and nesting insects.
Many log homeowners use silicone to fill large gaps. There is always a chance that the silicone will fail. This can sometimes be worse than doing nothing. Moisture will get into the caulking and not evaporate as fast. This can increase the chances of insect and decay problems. Caulking success is dependent on a few key elements.

You should first choose caulking that is specifically made for log homes. You should ensure that the logs are free from oil and dirt. The backer rod is an important component of caulking. A backer rod is used as an insulator and filler, which helps reduce the amount of caulking required. The backer rod, which is a filler and insulator, will allow the caulking to adhere to the log above and below the joint.
The backer rod will not allow the caulking to adhere to it. This allows the caulking's flexibility to be stretched like a rubber band. The caulking will stick to the top, bottom, and area within the joint without a backer rod. This is known as three-point adhesion. The caulk, substrate (log surface), or adhesive will most likely fail if the gap grows.
