Step 1 Seal your Paint Can
One of the most important parts of paint storage is making sure your lid is tight and secure. Make sure to clean any paint from around or inside the rim of the paint can, and then tap the lid closed with a rubber mallet. Don’t use a normal hammer, as you can easily warp or bend the lid and cause it to not fit tightly. If you don’t have a mallet, you can lay a flat piece of wood across the top of your can and use a regular hammer to tap the wood. This will ensure that you don’t damage the lid.
