What is the difference between chinking and caulking?

What is the difference between chinking and caulking?

“Chinking” in the log home industry has come to mean an elastic sealing material that looks like the old-fashioned Portland cement-based mortar in color and/or texture, used to seal the joints between logs. Chink lines can be fairly narrow or pretty wide. Backer rod or bond-breaking tape should always be used in back of the chink line in order to provide 2-point adhesion and allow the chinking to expand and contract to the maximum possible degree. Log Jam and Chinker’s Edge are both excellent chinking products.

“Caulking” is a similar material to “chinking”, but usually has no texture or a very light texture. Caulking also generally has more elasticity than chinking products. Because of this, caulking works better in smaller joints (i.e. Ľ” to 2” wide). Caulking can be used to fill the horizontal cracks (called checks), create a continuous caulking line between the log rows, or as a stacker during construction.
