SOCRRA's Latex Paint Guidelines Video

Latex-Paint Guidelines Script

In response to questions regarding what to do with old latex paint cans, SOCRRA has developed some simple guidelines on how to deal with leftover latex paint. Because latex paint is technically not a Household Hazardous Waste, it is recognized as a liquid and therefore cannot be placed in with the trash, which is considered solid waste. Instead, SOCCRA asks that latex paint first be dried or hardened before it is disposed of in the trash, and that the empty paint cans be placed in the recycling bin. Because oil-based paint contains dangerous solvents, it is important to remember that these procedures can only be used with latex paint. Here are the options we recommend:

Natural Drying - With paint cans that are less than a quarter full, simply remove the lid and place the can in a well-ventilated area. The remaining paint should be dry within a few days. Once dry, the hardened paint can be chipped out and placed with the trash. The empty paint can, whether metal or plastic, should then be placed in the recycling bin.

For paint cans that are more that a quarter full, you’ll need:
Paint Hardener - You can pick up paint hardener at any local hardware or paint store. Once you have your paint harder there are a few simple steps to follow:

Cover your work surface to protect it from paint splashes
Add a paint hardener to the can – read the directions on the packet to find out how much hardener you need to add. Typically one packet will harden up to 2/3rds of a gallon of paint.
Stir and mix thoroughly. After a few minutes, the paint will have a chunky, oatmeal-like texture
You can now dispose of the dried paint in the trash. The empty paint can be placed in the recycling bin

Kitty litter - This common, household absorbent works well in removing the moisture from latex paint. How much kitty litter to add depends on the makeup and age of the latex paint. In most cases, start with a cup or two and add as needed. Stir thoroughly and after a short time, the paint will thicken. Dispose of the hardened material in the trash and recycle the empty paint cans.

Saw Dust, Mulch, Small Animal Bedding, & Sand – These are other common absorbents that can be used to thicken and solidify latex paint. Use them the same way you would use kitty litter. Remember to recycle empty paint cans and lids after disposing of the hardened paint.

Some general tips to consider before drying latex paint: to limit waste buy only what you need – ask at the paint stores, they are the experts! Store cans in a proper place, properly sealed, so the paint doesn’t leak or dry out. Storing paint cans upside down can help keep paint fresh. Try to use all of the paint up. Donate any leftover paint to local schools, churches, and theatre groups.
