Proper Paint Disposal Tips for Knoxville Homeowners

From Your Local Experts at CertaPro Painters® of East Tennessee

Whether you’ve just wrapped up a major home repaint or tackled a DIY accent wall, knowing how to properly dispose of leftover paint is an important—but often overlooked—part of the job. Improper paint disposal can harm the environment, clog plumbing, and even result in fines. At CertaPro Painters® of East Tennessee, we’re not only committed to delivering exceptional painting results, but also to helping homeowners in Knoxville make eco-friendly, safe choices after the work is done.

Why Proper Paint Disposal Matters

Paints contain chemicals that can pose serious risks to both human health and the environment when not handled properly. These risks vary depending on the type of paint, which is why disposal methods should never be one-size-fits-all. Let’s break down the right way to dispose of the most common types of paint.

🟦 Water-Based (Latex) Paint

Water-based or latex paint is the most common paint used for home interiors and exteriors. Thankfully, it’s also the easiest to dispose of properly.

Here’s how to safely get rid of leftover latex paint:

• Dry It Out First: Latex paint must be completely dry before being placed in the trash. This prevents spills and makes it landfill-safe.

• To dry small amounts, simply remove the lid and let the paint air dry in a well-ventilated area.

• For larger quantities, you can mix the paint with kitty litter, shredded paper, or commercial paint hardener to speed up the process.

✅ Once dried, latex paint can go in your regular household trash (with the lid off).

🟥 Oil-Based Paint

Unlike latex, oil-based paint is classified as hazardous household waste. It contains chemicals that can contaminate local water systems and harm wildlife if disposed of improperly.

Never pour oil-based paint down the drain, into storm sewers, or place it in household trash.

Here’s what to do instead:

• Contact a Local Hazardous Waste Facility: Knoxville homeowners can bring oil-based paint to:

  Household Hazardous Waste Facility
  Located within the Solid Waste Facility
  1033 Elm Street
  Knoxville, TN 37921
  ☎️ 865-215-6710
  Visit the facility’s website for current hours.

• Be sure to transport containers in an upright position and keep lids tightly sealed.

💡 Tip from CertaPro Painters® of East Tennessee: If the paint is still in good condition, check with local nonprofits, schools, or theaters—some may accept donations for set design or maintenance projects.

🟧 Specialty Coatings, Stains, and Varnishes

These finishes often contain solvents and resins that are harmful if leaked into soil or water systems.

• Like oil-based paint, they must be disposed of through approved hazardous waste channels.

• Never dump them outdoors or in household drains.

What About Reuse or Recycling?

Before you toss that half-used can of paint, consider whether it could be reused:

• Touch-ups: Keep small quantities on hand for scuffs or repairs.

• Crafts or smaller projects: Leftover paint is perfect for sprucing up furniture, planters, or trim.

• Paint Exchanges: Some local hardware stores and community centers offer paint recycling or exchange programs.

At CertaPro Painters® of East Tennessee, we aim to minimize waste on every project by accurately estimating paint quantities—and we’re always happy to leave leftover product with you for future use.
