When buying paint, estimate correctly how much you need. Average coverage rate is 400- 450 square feet per gallon. For leftover paint, try to use it up. Paint extra coats on closets, cabinets, or even sheds. Try to donate it to someone who may use it: friends, neighbors, churches, high schools, theaters, or other organizations.
