A few years ago we purchased an investment house that came with a multitude of problems. One of the least was the 35 gallons of ancient paint in the basement. Some was even lead based. This was a small town and no local hazardous waste facility. It took a lot of research, but I finally found through the local trash company’s main office a knowledgeable woman who gave me the instructions on how to dispose of all the old paint.
It took 6 months, a 5 foot tall stack of cardboard and newspaper and 300 pounds of kitty litter to accomplish. We only have 4 gallons to do here so this will be a quick process.
STEP 2 – Open the cans and arrange the lids paint side up along the bottom of the boxes on top of several layers of old newspaper.
STEP 3 – Sprinkle a substantial layer of clay based kitty litter over the can lids.
STEP 4 – Pour the first can of paint over the kitty litter and spread even with a paint stir stick.
STEP 5 – Sprinkle another layer of kitty litter on top and allow to dry. This process can take anywhere from 2 weeks to 2 months depending on the paint consistency and amount. Ideally you want to make very thin layers and not make the boxes too heavy to lift.
STEP 6 – Sprinkle kitty litter all over the insides of the empty cans.
STEP 7 – When the paint is dry, toss the whole mess in your trash can. Simple as that.
