Disposal of Latex & Acrylic (water-based) Paint
The best thing you can do with unused, water-based paint is to use it up. If you cannot find a use for it (and are unable to find someone who can use it), the paint in the can must be dried up completely prior to disposal.
​
There are three ways to accomplish this. All methods require drying time in a well-ventilated, covered, warm (over 60°F degree) location, out of reach of children and animals. Dispose of lids separately; metal lids and cans may be added to a scrap metal recycling pile once residual paint has completely dried.
​
-
Thoroughly mix in clean kitty litter or “Speedy Dry or Oil Dry” until the consistency resembles thick oatmeal.
Approximate drying time = 3-7 days. -
Purchase a packet of powdered paint hardener from your local hardware or paint store, and add the recommended amount into the container per instructions. Mix thoroughly with a stir stick.
Approximate drying time = 1 day. -
(Do this for small quantities only) Place a small, shallow, cardboard or shoe box with a tight bottom seal (no holes) on top of a thick layer of newspaper. Empty the paint into the box and let it dry completely.
Approximate drying time = 3-7 days.
​
After the paint is completely dry (not just a thick surface layer), you may bring the lid-free container to Valley Recycling for disposal @ $1.00 per dried up paint can up to 1 gallon.
​
Empty dry metal paint cans and can lids can be disposed for free in the metal recycle bin

Important: Only water-based paints may be disposed of using the methods described here. All oil and solvent-based paints must be taken to a household hazardous waste collection for disposal. Call your town to find the next hazardous waste collection date.
