Chinking is a flexible sealant that is used to seal the joints of log homes. No matter what type of log property you own, it is important to use chinking, a synthetic mortar, to keep the log joints sealed.Click to see full answer. Just so, what is log home chinking made of?Traditionally chinking was a mixture of clay lime and sand with variations based on what was locally available. Today we use an acrylic elastic compound that adheres to the logs and can stretch and contract as the logs settle and move seasonally.Also Know, do all log homes need chinking? Virtually all log homes are chinked. Yes, even ‘chinkless’ log homes usually have some form of chinking. That’s because it’s hard to find a craftsman using the old tradition of real form-fitting notchwork. And rarely do commercial builders properly air season their logs due to time constraints. Accordingly, how do you fix a chinking in a log home? It’s easier to make a repair using a tube of chinking or a bulk loading gun than it is to scoop some out of a pail. Put a bead of chinking along the tear, making sure that you have good contact with the torn chinking and the wood. Once it’s applied, you can press it into place with a tool or your finger.What is the difference between caulking and chinking?The main difference between chinking and caulking is texture and elasticity. Caulking is more elastic than chinking and has no texture or very light texture; while chinking comes in various colors or textures. Due to higher elasticity caulking is a great option for using it in smaller joints (i.e. ¼” to 2” wide).
