How To Repair Bumper Cracks? - Simple Guide

Wondering how to repair bumper cracks? Our blog is here to help you understand how to do so, depending on the severity of the issue and how much experience you have, to fix your vehicle. Bumper cracks can be caused in many ways, some more minor than others. Like most occasions, leaving your vehicle with even the smallest of issues can always lead to more developed problems. Don’t let that occur, and let us help you at Dinks Auto Repair.

What Causes Bumper Cracks?

Bumper cracks are usually caused by everyday accidents or wear and tear. They often happen when you least expect it. Here are the 5 most common reasons your bumper might crack:
 

Low-Speed Collisions: A small bump in traffic or a car park can be enough to crack a plastic bumper.
 

Reversing Into Objects: Something as simple as reversing into certain objects, such as bollards or walls, could cause this damage.

Hitting Curbs or Parking Stops: Pulling in too far and catching the bottom of the bumper on a curb or concrete barrier can cause cracks, especially underneath.
 

Cold Weather: In colder temperatures, plastic becomes more brittle and more likely to crack (even from a light knock).
 

Previous Damage: Bumpers that have been poorly repaired before or are already weakened are much more likely to crack again, even under minor pressure.

Can You Repair A Cracked Bumper Yourself?

With repairs like bumper cracks, there is the possibility of being able to repair them yourself with thorough research and delivery. For small, surface-level cracks, it is possible to do a decent job at home. Although reassurance and trust in your vehicle are crucial and tampering with equipment and car parts that you may not need could cause further problems. Here is a simple guide to know how to repair bumper cracks:

Clean the Area: Wash off any dirt or grease around the crack, then dry it completely. This helps your materials stick properly.
 

Sand the Surface: Use sandpaper to smooth the edges of the crack and roughen the surrounding area to help the filler bond.
 

Apply Plastic Filler or Epoxy: Depending on the size of the crack, you’ll need to apply plastic repair adhesive to both the front and back of the bumper. Let it cure fully.
 

Sand Again: Once the filler has hardened, sand it down until smooth and level with the bumper’s surface.
 

Prime and Paint: Apply automotive primer, followed by colour-matched spray paint and a clear coat for a professional-looking finish.

Despite there being ways to fix your car yourself, there are always risks. In order to save you time and resources, come and visit our workshop or fill in your needs via our enquiry form.

How Our Professionals Focus On This

Professional bumper crack repair is a detailed process that restores both the appearance and structural integrity of the damaged area. First, the vehicle is carefully inspected by our team at Dinks to assess the extent of the crack and determine whether a repair or full replacement is necessary.

If we notice that the bumper can be repaired, it is often removed from the vehicle to allow full access. The damaged area is then cleaned and sanded to remove any loose material and prepare the surface. 

We use specialised plastic welding equipment or high-strength fillers to seal the crack from both sides. Once the structural repair is complete, the area is smoothed, primed, and repainted using precision-matched automotive paint. Finally, the bumper is reinstalled and the repair is thoroughly inspected to ensure it meets professional standards, leaving your vehicle looking as good as new.
