What is Caulking?

The term ‘Caulk’, ‘Caulking’, and ‘Caulker’ all derive from the oldest of nautical trades in which ‘caulk’ was used to seal leaks in ships. Here is the dictionary definition…

caulk (v.)

late 14c., “to stop up crevices or cracks,” from Old North French cauquer, from Late Latin calicare “to stop up chinks with lime,” from Latin calx (2) “lime, limestone” (see chalk). Original sense is nautical, of making ships watertight. Related: Caulked; caulking. As a noun, “caulking material,” by 1980 (caulking in this sense was used from 1743). Related: Caulker.

Is there a Difference Between Silicon Caulking & Joint Sealing?

No. Silicon Caulking is exactly the same as Joint Sealing and the terms are interchangeable. ‘Joint Sealing’ is the modern day term now commonly used in the construction industry for internal & external joint sealing.
