Latex paint is not hazardous. There are no special collection programs in Cuyahoga County for latex paint. Dry it out and place it in the trash for proper disposal.
To Solidify Latex Paint:
- Air dry. Remove the lid and allow the liquid 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.
- Use a drying agent. Mix an equal amount of an absorbent material into the can and allow the paint to dry. Use cat litter, sawdust, plaster of Paris, Oil-dri, or “waste paint hardeners” found at home improvement centers. The paint could dry quickly, depending on how much drying agent you include in the can.
- 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 paint has hardened.
- Once the paint is thoroughly dry, place it in a regular trash bag and put it out with your weekly trash collection.
