Tools Needed

Steps on How to Paint a Bumper Cover Yourself

  1. Pick a Warm Sunny Day or a Garage That’s Well-Ventilated

    Pick a warm day to do this repair, or paint the bumper in a well-ventilated area. This is a meticulous job to do inside, so pick an area like a garage that’s well-ventilated if you’d rather not paint outdoors.

    You will need to fix the bumper outside on a warm sunny day if you do not have a paint booth. Pick a day that’s not too windy so dust or pollen can’t attach to the bumper. Watch out for bugs since some may attach to the bumper during the job.

  2. Warm the Bumper Up in the Sun

    Leave the bumper outdoors in the sun. Place it on stands and let it warm it up for about ½ hour to 1 hour.

  3. Wash the Bumper Cover

    Wash the bumper cover like you’d wash your car. Rinse it with water, clean it with soapy water and scrub it well, and then rinse the soap off.

  4. Dry the Bumper Cover

    Dry the cover off with compressed air or a towel.

  5. Wipe the Bumper with a Scuff Pad

    Take a non-abrasive scuff pad and wipe the whole bumper down. Scuff up the bumper so the primer and paint will stick better.

  6. Inspect the Old Bumper and Place Tape Over the Sections that Don’t Need to Be Painted

    Look at the old bumper and find out what sections need to be painted and taped off.

    Place painters tape over every section of the new bumper that you do not want to paint.

  7. Remove Dirt and Debris from the Bumper with a Tack Cloth

    If you have a tack cloth, pat the bumper down and remove any dirt, dust, or debris so you don’t have any underneath the paint.

  8. Spray Primer on the Bumper

    For this plastic bumper, we used plastic adhesive promoter primer.
    Shake up the can, follow the directions, wear a mask, and spray primer on the bumper. The primer will look clear. Keep 10 inches to a foot away while spraying.

    In our example, we applied 3 coats. We sprayed one coat every 3 minutes, and let the primer dry for 10 minutes before putting the paint on.

  9. Paint the Bumper

    After the last coat of primer has sat for 10 minutes, it’s time to paint the bumper. You might have to warm up cans of paint depending on how warm it is outdoors. Place the cans in a bucket of warm water so the paint is at least warm.

    With the bumper primed, first paint areas where paint is likely to pool up, like the edges of the tape and slots on the bumper. Then paint a nice thin coat on the rest of the bumper, back and forth in sweeping motions.

    Wait 10 minutes before applying the 2nd coat. Let the bumper sit for 10 minutes after the last coat.

    Pro Tip: Order more cans than you think you’ll need to be safe. In this example, we went through 3 cans, but 4 cans would’ve been better

  10. Apply Clear Coat

    After the bumper has been painted and 10 minutes have passed, use clear coat and apply it in the same way you applied the paint. Put on a thicker coat than the paint for a nicer finish. Don’t make it too thick so you don’t have any runs or drips, and wait 10 minutes between coats.

  11. Let the Paint Dry for 24 Hours after the Last Coat

    Let paint dry for 24 hours after the last coat of clear coat is applied.

  12. Remove the Tape After the Bumper Is Dry

    Once the bumper has dried for 24 hours, remove the painter’s tape from the bumper. If the tape is sticking, you might need a razor blade.
