Cracked Chinking: If a log joint is deeper than 1/4 in. and backer rod was not used, there is a very good chance that the chinking will crack. What happens is the logs will naturally expand and contract and since there is no bond breaker to allow the chinking to stretch in the middle, the caulking or chinking cracks in the center.
Depending on the condition of the caulk or chinking, the material could be completely torn out, backer rod installed and then caulk or chinking reapplied. An alternative to removing all of the material is to run a length of packaging tape down the middle of the joint, over the chinking material as shown on the right (the tape will act as a bond breaker). Then cover the old caulking and packaging tape with a new layer of caulk or chinking as shown.
