Storing Leftover Paints: Step-by-step

  1. Clean the plastic or glass containers first. If the storage containers are full of dust, dirt, and other debris, we advise you to wash them thoroughly to remove these wastes. For drying the containers up, use clean clothes to wipe the wet areas.
  2. Transferring your excess paints from canned paint to containers. Use funnels to avoid potential spillages. If there are no available funnels, you can use soda bottles instead. Cut the top head using scissors or craft knives.
  3. Position the funnel or your DIYs into the plastic or glass containers. Pour the paint leftovers slowly and gently to prevent a big mess.
  4. Before you close the container, clean the paint residues around the mouth to make it easier to open. Apply cut out plastic wrap more considerable than the opening of the storage containers.
  5. Afterward, seal them tightly to the point which the air cannot enter. You can use a rubber mallet to hammer containers. Don’t hit the lid directly to prevent the distortions that play havoc with air exposures. Instead, put the block wood on the top of the cover and hammer it smoothly.
  6. If you want to maintain the storage well-organized, label the storage containers with sticker papers, stick-on sticky notes, or permanent markers. You can also use paper and apply masking tapes efficiently. Ensure necessary details such as colors, brand name, and parts of the house paints are used.

Considerations in Storing leftover paints

  • Choosing containers – Paint quality goes bad when contaminated with air. It’s better to choose airtight plastic or glass containers to prevent exposure.
  • Temperature – Keep in mind that some paints are flammable and can burn your house down. Plus, aside from air that can ruin the quality, extreme temperatures will dry the paint until it becomes solid, making them unusable.
  • Storing locations – Store the paint containers in a dry and cool area. The basement is the best place to store your paints. If you don’t have a basement, put it in a cupboard.
