Latex paint, once solidified, is non-hazardous and can be disposed of in your normal trash receptacle. The disposal method below is for latex paint only. Be sure to thoroughly read the paint label to understand if your paint is latex or oil-based. The Household Pollutant Collection Facility does accept oil-based paint, but not latex paint.
Some key words to help identify latex paint are: latex, soap and water cleanup, acrylic, non-flammable, and water listed as the first ingredient.
Words to look for on the label to help identify oil-based paints are: oil-based, mineral spirits cleanup, alkyd, flammable or combustible, and petroleum distillates.
To properly dispose of unwanted latex paint, simply remove the lid in a well-ventilated area and let the paint solidify. Depending on the amount of paint, this may take several days to weeks. Once the paint is solidified and there is no liquid left in the container, it can be disposed of in your normal trash.
If you have any questions about this process or the City of Tulsa's Household Pollutant Collection Facility, please feel free to call (918) 591-4325.
