We’ve all ended up buying too much paint at some point in our lives. Here is how you should store your leftover paint correctly. 1. Choose The Right Container The key to storing leftover paint properly is using the correct container to keep it in. Canning jars are perfect for this task as they form an airtight seal. Use a funnel to transfer the paint from the can to the jar. If you don’t have canning jars, try placing plastic wrap over the tin before putting the lid back on and securing it tightly. 2. Label The Container The next thing you should do is label the container, so you know exactly what paint it is in the future. Put the brand, color, type, finish and room on the label to make it easy for yourself. 3. Keep It In The Right Place It’s best to store paint in a cool, dry spot away from sunlight. The temperature in the space also needs to stay above freezing.
