Can You Put Paint in a Dumpster?
Liquid paint: no, not in our trailer, not in any dumpster, not at any landfill gate in Colorado. Dried-out paint: yes. Here is the difference and the easy free option most people miss.
The Rule
No facility in the metro accepts liquid paint, and a can that leaks in a load can get an entire trailer rejected at the gate, which becomes everyone's expensive afternoon. Fully dried paint is ordinary solid waste: cans with hardened residue, lids off, are fine in the trailer.
The Free Option: PaintCare
Colorado runs a paint stewardship program called PaintCare, funded by a fee you already paid when you bought the paint. Participating paint and hardware stores across the metro take leftover house paint, stain, and varnish at no charge. If you have usable paint, this beats drying it out and is genuinely free.
How to Dry Out the Rest
For the half-inch of dead paint in the bottom of a can: pop the lid, stir in kitty litter or paint hardener, give it a day. Once it is solid, the can goes in the trailer with the lid off so the gate can see it is dry. A dozen cans takes one bag of litter and zero trips.
