How do you dispose of paint? Here are the methods that you should use during paint disposal.

How to dispose of latex paint

Latex paint is composed of water and is easily cleaned up using water. This makes it relatively easier to dispose of.

For latex paint disposal, do the following:

Let it dry completely

If there's less than a quarter of a can left, let the paint sit in the sun away from kids and pets until it dries out.

If you have more than half a can remaining, you could add a hardener or kitty litter to the paint to solidify it.

Does kitty litter dry up paint? Yes, it does. When using cat litter, follow these steps:

  • Add equal parts cat litter to latex paint in the can. If the can is more than half full, pour the paint into a lined box or trash can then pour in the cat litter.
  • Next, stir in the cat litter into the paint until it thickens and won't spill.
  • Allow the mixture to sit for one hour. It might take more than one hour for the mixture to dry out, depending on how much you have.

If you decide to use a hardener, note that the hardener will turn the leftover paint solid. Once it's solid, scoop it out of the can and dispose of it normally, then recycle the can.

Another method you could use involves using a newspaper to soak up the paint and speed up the drying process.

Throw away the can

After the paint has dried out completely, throw the dried can in the garbage. Make sure you remove the lid.

You could also call a recycling center or your local waste management authority and ask if they could collect it.

How to dispose of spray paint

Here is how to get rid of paint that comes in spray cans:

  • You will need to use any of the remaining paint in the can because the pressure can make it unsafe. Use any of the remaining paint on a spare cardboard box or things you're going to dispose of.
  • Once dried, recycle the can. Note that not all recycling facilities will accept spray cans, so you have to check with them first.

As you can see, the methods of disposing of paint depend on the type of paint you are dealing with. Before you begin getting rid of old paint, you need to determine which type you're dealing with.

Other tips and FAQs

Here are some tips that might come in handy:

1. Store paint correctly

Water-based (latex) paint has a shelf life of 10 years. Oil-based ones have a shelf life of 15 years if stored in a cool, dry place with proper can sealing. Due to its long shelf life, you can keep paint for many years and use it when needed.

But to keep it fresh, you need to store it properly. Here are tips on how to properly store paint:

  • Keep it in its original container with the original label. You should also include the date when you opened the can and the room it corresponds to.
  • Seal the can - cover the opening of the can with plastic wrap.
  • Put the lid on securely and make sure it does not leak.
  • Turn the can upside down to allow the paint to create its seal.
  • Store the can upside down in a cool, dry place away from sunlight, safe from freezing, and out of reach of kids and pets.

To avoid having anything left over, use a paint calculator to calculate the amount you need for a specific project.

3. Know when paint has gone bad

Before getting rid of old paint just because it is old, you first need to determine whether it has gone bad or can still be used.

Paint has gone bad if:

  • It smells more pungent than it usually does
  • It's been around longer than a decade.
  • It is hard after stirring
  • It looks rubbery

4. How do you harden paint?

Mix an equal amount of absorbent kitty litter or sawdust into the paint. The moisture will absorb into the litter or sawdust over the next few days, hardening it. Leave the lid off as it hardens.

5. Can empty paint cans be recycled?

Yes, they can. Empty steel cans are recyclable where steel recycling is accepted
