• Buy water-based latex paint over oil, when possible.
  • Buy only what you need. One gallon of paint will cover 300 to 400 square feet.
  • Try to use up all paint on each project.
  • Store paint correctly and it will last for years. Store your paint can upside down. Yes ¡¦¡¦ that's right. The paint will create a tight seal around the lid, keeping the paint fresh until you need it again.
  • Use up any stored paint before buying new.
