The short answer: Never pour paint down a drain, storm sewer, or onto the ground, and never put liquid paint in your trash. For latex (water-based) paint, dry it out completely — stir in kitty litter, sawdust, or a paint hardener — and most landfills will then accept the solid, dried can. For oil-based paint, stains, and solvents, treat them as hazardous and take them to a household hazardous waste (HHW) facility or collection event. When in doubt, take it to HHW.
Leftover paint is one of the most common things people get wrong, partly because the rules depend on what *kind* of paint you have. Here’s how to handle each one in Texas.
Latex vs. oil-based: which paint do I have?
Check the can. Latex or acrylic paint is water-based — cleanup is soap and water. Oil-based (sometimes labeled alkyd) paint, along with stains, varnishes, and the solvents used to clean them, are flammable and considered hazardous. The two are disposed of very differently, so identify yours first.
How do I throw away latex (water-based) paint?
Liquid latex paint isn’t allowed in the trash, but dried latex paint usually is. To dry it out:
- Small amounts: leave the lid off and let it air-dry in a well-ventilated spot away from kids and pets.
- Larger amounts: stir in an absorbent — cat litter, sawdust, or a store-bought paint hardener — until the paint is solid and no longer pours.
- Once it’s fully hardened, most landfills and transfer stations will accept the can. Some prefer the lid off so they can confirm it’s dry.
Always confirm your facility’s rule first — a few accept latex differently, and the dried-can method is the most common but not universal. Check what your nearest facility accepts before you go.
How do I dispose of oil-based paint, stain, or solvent?
These don’t go in the regular trash at all, even dried. They’re hazardous and belong at a household hazardous waste facility or event:
- Keep the paint in its original, labeled container.
- Don’t mix products together.
- Take it to an HHW drop-off. Find a household hazardous waste site near you and check the day and hours, since many run by appointment or on event dates.
HHW programs also take the related materials people forget about — turpentine, mineral spirits, brush cleaner, and aerosol spray paint.
Can I donate or reuse leftover paint instead?
Often the best option. If the paint is still good:
- Give it away to neighbors, community theaters, schools, or buy-nothing groups.
- Use it up as primer or on a fence, shed, or garage where the exact color doesn’t matter.
- Combine like with like — several cans of similar latex can be merged into one usable batch.
Reusing paint avoids disposal entirely, which is cheaper and greener.
What you should never do
- Don’t pour paint down the sink, toilet, or storm drain — it pollutes waterways and can violate local ordinances.
- Don’t dump it on the ground or in a ditch — that’s illegal dumping in Texas.
- Don’t put liquid paint of any kind in the trash — let latex dry first, and route oil-based to HHW.
FAQ
Can I put paint cans in the trash in Texas?
Only if the paint is latex and fully dried out. Liquid paint of any type isn’t allowed, and oil-based paint must go to household hazardous waste even when dry.
How do I dry out latex paint fast?
Stir in cat litter, sawdust, or a paint hardener until it’s solid. Hardeners work fastest; thin amounts can simply air-dry with the lid off.
Where do I take oil-based paint?
To a household hazardous waste facility or collection event. Keep it in the labeled original container and don’t mix it with other products.
Is it illegal to pour paint down the drain?
You should never do it — it contaminates water systems and can breach local rules. Dry out latex or take hazardous paint to HHW instead.
