Caulk

Definition

Includes caulks, wallboard mud, joint compound and spackle.

Disposal

Solvent-based caulk is flammable. Bring it to the household hazardous waste collection sites for free. Empty containers go in the trash.

Latex or water-based caulk is safe to put in the trash. If the label reads "soap and water clean-up," the product is not flammable.
