Leftover paint should never be thrown in the trash and can often be donated for reuse or resale. Paint poured on the ground, into storm drains or put in the trash could end up in groundwater and streams. If you buy only as much paint as you need to complete a project, you will save money and avoid waste. To store paint for long periods of time: Cover the opening of the paint can with a piece of plastic wrap and seal the lid tightly. Store the can upside down and away from heat. Ideas for leftover paint: Apply a second coat or use for touch-up. Stencil or sponge-paint walls or furniture. Mix latex paint together to use as a base coat (mix interior with interior; exterior with exterior). Give it away. Check with neighbors, friends, theater groups or community organizations to see if they could use it. Paint a fence, shed or your doghouse. Latex-based Paint Small Amounts: If you have one inch or less of leftover latex, dry it out and discard the can. Dry out latex paint by opening the can and letting it evaporate outdoors, away from children and pets. Dispose of the paint can with the lid off with your trash.
