You should remember that improper paint disposal can harm the environment. So, store unusable paints properly and safely before disposal.
· Keep the product in its original container with the label intact.
· Store products out of reach of children and pets, away from heat, and away from the house, if possible.
· Check the label in intact condition if any lead or hazardous materials are in product because lead and mercury may be found in older paints.
· Remove the lid and let the paint air dry outdoors. If you want to speed up the process, stir in an absorbent material.
· Take a look at the paint which it is completely dry and has no moisture, then wrap the dried clump in newspaper and place into your regular trash. Do not place the lid back on the can. Wrap the lid and can separately in newspaper for disposal. This technique works for latex paints because oil based paints require an extensive time to dry.
· You can purchase for “waste paint hardener”, if you need to get rid of a lot of latex paint. This powder mixed in with a gallon of paint will cause it to harden up within hours.
