The key to successful paint storage is to keep it in a cool dry place.

A dry basement is a good place to store paint, but wherever you decide to store your leftover paint, be sure to avoid places with high moisture because metal paint cans will quickly form rust around the lid and when opened, small pieces of rust will fall into the paint.

Here’s a good tip on how to store paint:

  1. Clean and remove all paint out of the sealing rim of the paint tin.
  2. Use a layer of plastic wrap as an added seal between the tin and lid.
  3. Store paint tins upside down, so the paint itself creates an airtight seal against the lid.
