If you have been hanging on to the paint you used in your living room for more than 10 years, toss it! It may be a match to the walls, but it probably won’t mix well when you try to stir it. Over time, latex paint forms bits that can cause the paint to go on unevenly. Always check with your community for disposal guidelines as some paint can be hazardous. If you have paint to dispose of, try paintcare.org to find a location near you.
