What Do I Do With Leftover Paint May 9, 2021 Email Got leftover paint from a home renovation or DIY project? Don’t worry, you’ve got some options for taking it off your hands. The first thing to know is that house paint and primers — and all latex and oil-based paint — are considered hazardous waste. It must be disposed of properly and should never be dumped down the drain. Improperly disposing of paint can be toxic to the environment and pollute water sources, harm fish and wildlife and even impact human health. Disposal Options Here are a few disposal options for paint that will ensure it can be recycled and used again. Take it to a participating hardware store. Some hardware and home improvement stores have paint-collection programs where you can donate leftover paint to be remixed and resold. Find a location near you.
