How To Repair Car Dashboard Crack?

The dashboard of your automobile is more than simply a feature-rich panel; it’s an integral element of the vehicle and a canvas that preserves memories of countless trips. Moisture and dust quickly gather on the dashboard. You subject the dashboard to temperature variations every time you turn on the car’s AC system or the heat. This can cause cracks to form over time, reducing the overall look of your vehicle’s interior.

This post will show you how to fix a cracked dashboard using low-cost components in a short amount of time.

Complexity Of Dashboard

A car’s dashboard consists of three layers. The bottom layer, a glass-fiber-reinforced thermoplastic, is not visible. On top of that is a layer of polyurethane foam. The top layer on older vehicles is, of course, PVC. Recently, dashboard covers have been composed of PVC mixed with something called ABS. ABS stands for acrylonitrile, butadiene, and styrene, a block copolymer.

PVC combined with ABS practically achieves the same result as PVC with an additional plasticizer, but the ABS does not evaporate, allowing the dashboard to stay much longer. Plasticizer is still used, however, because consumers appear to enjoy the new car fragrance!

Where Do The Cracks Come From? 

Your car’s dash is just below the windscreen, so it receives frequent sunlight exposure, which causes the vinyl’s PVC to progressively lose its chlorine content. After that, the coating hardens and becomes brittle, losing its ability to change its size in response to temperature. Then, the areas with more tension will see the first cracks form.

If you don’t address these issues immediately, the fractures will spread over your dashboard. The foam beneath will start to inflate as a result of absorbing moisture from the air. This results in the common crack that older cars frequently have.

It would take at least three days to remove and repair a dash that has cracks all the way through. As a result, you should act as soon as there is any damage because waiting will make the process more expensive and time-consuming.

Repairing Car Dashboard Cracks

1. Supplies You Need

  • Dashboard Repair Kit

  • Cleaning Solution
  • Putty Knife
  • Paint
  • Microfiber Cloth

2. Assessing the Damage

3. Preparing the Surface

Adhere precisely to the guidelines provided by the manufacturer, applying the filler in sparse layers and allowing it to completely dry between applications.

Once more, ensure that you adhere to the product’s instructions and give sufficient time for drying.

5. Sanding and Smoothing

It’s time to sand and polish the restored surface. Use fine-grit sandpaper to gently smooth away any excess filler until it is flush with the dashboard surface. Take your time with this stage, since a flawless finish will significantly improve the end outcome.

6. Painting and Finishing

After filling and smoothing the crack, it’s time to paint and finish the repair. Begin by applying a coat of paint that matches the color of your dashboard. Matching paint is available at most auto dealers or by contacting your vehicle’s manufacturer. After the paint has dried, use a clear coat to preserve the repair and give it a glossy appearance. Allow the clear coat to thoroughly dry before reassembling the dashboard.
