How to Remove Spray Paint Overspray

Ryan Lawrence

Removing paint drips and splatters can be a tedious, difficult endeavor. Because spray paint over-spray tends to go on light and wispy, the adhesives usually do not soak into the surface and bond.

Do not use a metal putty knife in place of a plastic one.

If you need to remove spray paint over-spray, appropriate removal techniques are necessary to avoid causing damage to the underlying surface.

Tip

Do not use a metal putty knife in place of a plastic one as this may scratch and scar the underlying surface. Do not mistake turpentine for lacquer thinner, a much harsher solvent. Do not use an unbuffered plastic putty knife to scrape over-spray away from wood, plastic, fiberglass, or vinyl or you may scratch and scar the underlying surface.

Fabric

  1. Lay the fabric flat on top of a wood board.

  2. Apply a few drops of olive oil to the over-spray.

  3. Allow the olive oil to soak into the over-spray for four minutes. Scrape away the over-spray with a plastic putty knife.

  4. Wipe the olive oil from the fabric with a rag dampened with turpentine.

  5. Wash the fabric with dish-washing detergent.

Brick and cement

  1. Remove as much of the over-spray as possible with a pressure washer.

  2. Apply lacquer thinner to the over-spray.

  3. Scrape away the over-spray with a wire brush.

  4. Rinse the surface with the pressure washer.

Wood, plastic, fiberglass, or vinyl

  1. Apply a few drops of olive oil to a rag.

  2. Apply olive oil to the over-spray with the rag.

  3. Wrap the wide scraping-end of the plastic putty knife with a rag.

  4. Scrape the over-spray free using the plastic putty knife buffered with the rag.
