caulking

Gap-sealing compound

Caulking is the material used to seal joints and gaps, preventing water, air, or pests from getting through.

It comes in tubes and is applied as a paste that hardens into a flexible seal.

You'll find caulking around bathtubs, windows, and anywhere two surfaces meet that need weatherproofing.

The old caulking around the shower had turned black with mildew.

The term also refers to the act of applying this sealant: I spent Saturday caulking the drafty windows.
