Latex paint can be easily dried out and disposed of, with the lid off, in your regular trash.
- Allow the paint to dry by removing the lid and allowing liquids to evaporate. This works well for small quantities of paint (an inch or two in the bottom of the can), and can take several days.
- Latex paint can also be solidified by mixing in an equal amount of an absorbent material and allowing it to dry. Use scoopable cat litter, sawdust, plaster of Paris, oil dry, or vermiculite.
- Pour thin layers (about 1″ of paint) into a cardboard box lined with plastic. Allow the paint to dry one layer at a time until all the paint has hardened.
- When thoroughly dry, the remaining hardened paint should be discarded with your regular trash. Leave the lid off the cans so that the waste collector can see that the paint is hardened.
- DO NOT dump the paint on the ground or down storm drains where it will travel directly to the surface and/or into ground water.
- DO NOT pour down the drain. While small amount of latex paint can be safely washed down the drain into a septic system or waste-water treatment plant, this practice should be kept to a minimum. Limit this to brush cleaning and cleanup.
- DO NOT throw liquid paint in the regular trash. It may be released from the can when trash is compacted and may seep out of waste collection vehicles onto your street.
