Paint Storage Tips

Paint products can become contaminated with bacteria or mold, which may lead to an odor that is strong, offensive, and in some cases, sickening. In addition, paints such as poster paints and tempera paints that are intended for classroom use and for use by children often contain an organic binder that is subject to degradation if not stored properly or used within a reasonable period of time.

To guard against bacteria and mold, manufacturers of paint products add preservatives to these products. Diluting the product will decrease the effectiveness of the preservatives. To maximize the shelf life of paints, follow these storage tips:

  • Store the product in its original container in a cool, dry place and prevent it from freezing.
  • Date and rotate your inventory, always using the oldest products first.
  • Thoroughly shake the product before using.
  • Remove only enough paint for immediate use. Never return unused portions of paint to the original container.
  • Never dilute the product. The addition of water dilutes the preservative's strength as well as the strength of the paint. If you are diluting paint to simulate watercolor techniques, prepare only enough paint for immediate use.
  • Avoid working directly from the original product container. Do not place brushes, hands, or other objects in the container.
  • After each use, make sure the cap is on tightly and that the product is securely sealed before storing.

All paints are subject to eventual spoilage after they are opened and exposed to air and other contaminants. Most spoilage is a result of cross-contamination from common sources such as air, water, contact with humans, brushes, and other tools. Proper storage and usage will reduce potential sources of contamination and extend the life of your paint products.
