When doing plastic bumper repairs Sydney, there are certain important things you should keep in mind. Fortunately, for your bruised plastic bumper, repair materials are available and simple to use. Repairing a plastic bumper involves grinding the affected area, sanding, sculpting, and painting. However, it is worth the effort for bumper repairs that would cost less money than your deductible.

Choose your adhesive and prepare the fascia

After removing the plastic piece from the car bumper, you will need to work in a warm and dry place so that the repair adhesives can cure. The adhesives you need depend on the type of plastic you are dealing with. The first step should be to find a stamp on the inside of the bumper and label it as TRUR, PUR, TPE, PPO or PP. when you buy your repair products, you should consult with the seller at the auto body store to determine which recipe is right for the plastic of your bumper. You should stick to the same brand for your products to ensure compatibility.

Start by slightly scuffing the area and cleaning it with a surface cleaner meant for plastics. If your bumper is torn through completely, scrub the outer and inner surfaces. After rinsing the area and allowing the surface to dry, wipe the area with a prep solvent.

Grind a V

Allow the solvent to dry and sand the area with 80 grit sandpaper. You will need to make a V groove in the damaged area on both the back and front sides of the fascia to ensure quality car bumper repair. The grooves allow you to align the edges easily. They also provide enough surface area for the repair materials to adhere to.

Mix the adhesive and fix tears

Repair cuts and tears from the back side. If the tear or cut is large, you might need to align and hold the edges of the repair with quality masking tape on the surface. Use self-stick fibreglass repair tape and add structure to the tear or cut.

Mix equal amounts of hardener and your repair adhesive on a piece of paper or cardboard and apply it over the tape with a squeegee.

Spread the filler

After the material has hardened, move to the front of the fascia and remove the tape. Using 80-grit sandpaper, remove materials that may have squeezed through and sand spots that are above your finished level. Fill the tear or cut and any low spots on the fascia with the right repair material.

Sand and contour

Let it harden and then sand everything level. Start with 80-grit sandpaper and proceed to 120-grit sandpaper and apply a light skim coat of repair material to fill any imperfections and restore the contour. Finish with 400-grit paper.


After finishing the bumper repairs Sydney, apply two wet coats of flexible sealer. Let it dry for 30 minutes and the fascia will be ready for priming. Prime it and paint it properly.
