CAR PLASTIC BUMPER REPAIR

Now that you know most of the things about our service, we are going to clear your concerns. Most people don’t understand how we are going to repair their extremely damaged plastic bumper. Therefore, we are going to tell you about how the car plastic bumper repair goes?

Steps that expert car plastic bumper repairers follow

1. Choose an Adhesive and Prep the Fascia

Once the bumper is detached from the car, take it to a dry and warm place because the adhesives need to work fine. There are multiple types of adhesives for different bumper types. Hence, one should consult the car parts store counterman that which adhesive material is best for your bumper type. Then get that item with all other required items and get to work. But we don’t need further information as we already have lots of experience, in fact, if you or your instructor needs help, we’re just a call away.

Usually, there is PP, PPO, TPE, PUR, or TPUR these five types of labels on your bumper plastic. Tell that stamped code to the counterman and ask which one would be better. After you’re done gathering all the items required for your plastic bumper repair, you will be good to go. But make sure that you only have the same recipe for all your car parts for the same operation.

Scuff the damaged area of the bumper with a surface cleaner especially made for plastic. Once your surface is clean and dry, wipe it down with the preparation solvent but move only in one direction.

2. Grind a “V”

Now sand the damaged area with an 80-grit paper and grind a “V” that will provide a lot of surface area for the repair material to adhere to. Also, the “V” shape will give you enough surface area for better placement.

3. Mix the Adhesive and Repair Tears

Now you need to mix the repair material of the adhesives and tears and apply it to the bumper where it’s cut or torn. Make sure that the repair material is equally mixed and that you have used the self-stick fiberglass-repair tape on the inside of the bumper. This will allow you to add structured grooves on the bumper if there were any. Then put the adhesives on a clean cardboard paper and apply it to the tape from the outside. Use a squeegee to do this for better results. To complete the filling, use another layer of the tape going at 90 degrees from the previous tape.

4. Spread the Plastic Filler

After completing the above step, wait for it to dry. Then, spread the plastic filler on the front side of the plastic bumper by removing all the tape or any leftovers. Use 80-grit sandpaper and sand the front surface of the bumper. If there are still any spots not filled or down the surface level, fill them with repair material. Then after waiting for it to dry, squeegee it equal to the surface.

5. Sand and Contour

Now after again waiting for it to dry, apply a very thin layer of the repair material on its surface. It will fill all the surface imperfections and unevenness; wait again for it to fry. Furthermore, in the last part of the repairing procedure, use 80—grit paper to sand, then 120-grit paper to make sure there’s nothing left to do. Finally, sand the surface with a wet 400-grit paper after contouring with the 120-grit paper on the surface. Sanding with a 400-grit paper will complete this procedure.

6. Paint

Before painting, you have to make it ready for it by applying two wet coats of the car plastic part sealer. Let it dry for at least 30 minutes and get it ready for priming first and then for painting. Now prime the surface of the bumper with a two-part primer-surfacer. But one thing is compulsory, let it dry between the coats so that it goes to perfection. And when it is dry and hardened enough to perform the next procedure, then remove any imperfections with 400-grit paper. Sanding it with that paper while it is dry is important to perfectly synchronize the surface of the plastic bumper.

Here comes the last part; the spraying part. But before going to spray the basecoat on the bumper, Wet sand the damaged area first, and then wipe gently to remove any dust or particles on its surface. Then go on with the spraying part. To properly spray the area, use the instructions of the manufacturers of your car. But when you are done with the first basecoat of the bumper painting, it may require you to do it twice and thrice. So, make sure to go through all this procedure one or two more times completely. And letting it dry between the coats is compulsory so that the paint sits in its position and does not drip off. After that, mix a clearcoat with the hardener, complete the medium clear coat and let it dry for like 30 minutes or more to completely let it dry. And then coat it one more time and again wait for it to dry. Once you’re done with all these coats, your car’s bumper is now ready to be installed on your car again.
