If you are a car owner, it is important to know how to do bumper repairs in Sydney on flexible bumpers. As the use of flexible bumpers in today’s vehicles grows, the need for effective and simple steps to repair plastic panels and bumpers also grows. Read this guide to understand the standard operating procedures for repairing minor damages to flexible bumpers. Some of the minor damages that can happen to flexible bumpers include bubbling, scratches, minor cracks on the bumper and so on. These standard operating procedures include cleaning the repair flexible bumpers properly, sanding the flexible parts and the use of a flexible plastic repair material and adhesion promoter.
It is important to note that damages such as tears and cracks that penetrate plastic are two-sided repairs and will require different procedures to fix.
Clean damaged areas
Cleaning the flexible repair area of your bumper can make subsequent steps easier and faster, and ensure professional and complete repairs. It is recommended that you clean the entire bumper with water and soap flowed by a surface cleaner that is VOC compliant to get rid of additional contaminants. You should clean the entire bumper if you want to identify any hidden damages. You need to use a microfiber detail cloth for your cleaning agents.
Initial preparation sand
You should start to refine the repair area and prepare your plastic bumper for the flexible filler materials. You should use a dual-action sander using an 80-grade abrasive disk, taper or dish out, the damaged area so as to create an area in the surface that is slightly lower during bumper repairs. You should refine the 80-grade scratches that surround the dish-out area using a DA sander and an abrasive disk of 180, removing the paint and creating an extension of the feathered area two to three inches beyond it. It is also important to have this extra surface space for your flexible filler, since applying flexible filler beyond the bumper repair edge can result in costly repairs.
Apply adhesion promoter
You should blow off the repair area using dry compressed air and then apply a light coat of adhesion promoter evenly to the area, coating the bare plastic. You should always apply adhesion promoter before applying any filler material. Let the adhesive promoter dry for five to ten minutes.
Apply flexible filler
You will need a flexible filler and use a manual applicator gum to mix and apply your flexible filler using a tight coat to ensure the substrate is wetted out with adhesive. Use thin wet-on-wet coats to build the area and ensure you keep the filler within the damaged bumper repair area.
Sand flexible filler
Use a hand block to sand the flexible repair material during repair flexible bumpers. You can approach this process the same way you would sand polyester filler on metal. Finish your bumper repair using a DA sander. Blow off with dry compressed air and inspect your repair job for quality.
