My husband and I have been working to clean out and better organize our basement this summer. In the process we found many cans of paint that we wouldn’t use again (old colors), or were nearly used up and didn’t need to be saved.
Many people think that latex and acrylic paint is considered to be a hazardous material, but in my town like many communities, you can toss dried up paint right in the regular trash. Sounds easy…but how to dry out the paint? I had heard that cat litter would do the trick, but could take a while.
I investigated options at our local hardware store and found that we could simply get a paint hardener to add to each can of paint. This is the one we used, but the hardeners are also available (and probably cheaper) in bigger containers. This was super easy and we cleaned out shelves of old paint from our basement.
Note: oil-based paints (and paint solvents) should be disposed of as hazardous waste. Check with your local town hall for more information for hazardous waste collection in your area.
