Latex paint, or water-based paint, is not
considered hazardous, and is not
accepted at local hazardous waste facilities. Latex paint should be dried out
and thrown away in your household trash.
To dry out latex paint, mix in kitty litter (or paint hardener):
1. Add equal parts kitty litter to the paint.
2. Stir until it reaches an oatmeal-like consistency.
3. Allow to sit for at least an hour.
4. Throw away in the trash with the lid off.
Consider using community sharing websites such as Nextdoor Kirkland or Buy Nothing Kirkland to give away usable paint. Limit wasted paint by using a paint calculator
to buy only the amount that you need.
