I'm Finished Painting - Now What?

By Steve Auger

Did you know that Americans use more than a billion gallons of paint every year?  Almost 40% of households do not know how to dispose of paint and end up storing left over's in the basement.

Here are some guidelines on how to wind up your painting project.  First have a look at how much paint is left in the can.  If you did a good job of estimating (before buying the paint) then you may have only a little paint left.  If this is the case then try to use it up by over painting areas previously painted.

Next, consider keeping/storing a mixture of leftover paints for future paint projects.  The mixture will tend to be a neutral blend and may be useable for undercoat.  When you store paint the opening should be covered with plastic wrap.  Then close the lid and use a mallet to seal the lid.  Store the paint can upside down to prevent drying out and store in a cool dry area. 

If you have more than 1/3 gallon of latex-based paint then you may be able to swap for another color through local paint swapping programs,  You may also find an organization such as a church, high school drama department, Habitat for Humanity chapter or community group that will accept donations.

In most areas, latex paint can be allowed to dry out and then disposed of as normal garbage.  You can dry the paint out by removing the paint can lid.  Add an absorbent material such as kitty litter to speed up the drying process.

If the paint is oil-based then it is considered hazardous material and should be dropped off at the nearest hazardous waste depot.
