Morphology

caulking = caulk (transparent) = caulk + ing

Standard noun/gerund formation from the verb 'caulk' yielding the material or action, so the meaning is directly derived.

Etymology

Caulking comes from an old French word meaning 'to stop up', so the idea is about blocking holes and seams. A helpful way to remember it is to think of caulking as a 'cork' or plug that fills a gap to keep water out, which is why it means a waterproof filler that makes joints watertight.
