Flushing paint down the drain is a no-go, so it’s important to find alternative methods for disposing of paint safely. The right way to do it depends on the type of paint you’re using. Here are the best ways to dispose of paint safely.
How to Dispose of Oil Paint
Oil-based paint is a hazardous waste that always needs proper disposal. Never throw it away in regular trash or pour it down the drain. It can contaminate water sources and harm the environment.
Look for a household hazardous waste (HHW) facility site or a hazardous waste collection event. In some cases, you may need to contact your local government or waste management facility to find out the proper procedures for disposing of oil paint. You may need to put the paint in its original container with a label and make sure that there are no leaks.
How to Dispose of Water-Based Paint
Acrylic and latex paints are water-based. They’re not as hazardous to the environment as oil-based paints. But there are still some rules to stick to when it comes to their disposal.
In some states, you can dispose of latex paint yourself. In others, you have to take it to a designated location. Always check your local regulations before you pick a disposal method.
Your disposal method may also depend on the amount of paint you have left over. If you have less than a quarter of a can of latex paint, you can let it air dry in the sun outside. Once it’s completely dry, you can dispose of it with your regular household trash. If you have more than a quarter of a can, consider donating it to a local community center or recycling facility that accepts latex paint. Or, take it to a household hazardous waste facility.
Alternatively, you can solidify your paint. One option is to use paint hardener, a chemical product that you can mix into the paint to solidify it. Once solidified, you can dispose of it with your regular household trash.
Maybe you’d never think that kitty litter has much to do with your home improvement projects. But you’d be wrong. In fact, cat litter can be used as a substitute for paint hardener. You can also use sand or sawdust as alternatives. These materials help absorb the liquid in the paint, causing it to solidify over time.
Remember to remove the lid and leave it open for the paint to dry completely before disposal.
