What is chinking? Where do I chink instead of caulk?
"Chinking" is now commonly thought of as a water-based, synthetic sealant that is textured like mortar and has considerable elasticity and flexibility. Twenty years ago, "chinking" was generally thought of as Portland cement-based grout that was applied to the joints between logs, reinforced with metal lath. The new chinking products, such as Log Jam and Chinker's Edge, far out-perform the old type of chinking.
Chinking can be used in most places where caulk would be used, but chinking is more commonly used in large joints between logs and when the building owner wants the nostalgic look of old-fashioned, textured cement grout.
