How to Repair Your Cracked Car Dashboard: A DIY Guide

A cracked car dashboard isn’t just an eyesore; it can significantly detract from your vehicle’s interior appeal and even affect its resale value. While a severely damaged dashboard might seem like a daunting fix, you have options to restore its appearance. Many dashboards, especially in older models, are constructed from rigid ABS plastic or vinyl layered over a foam padding. Repairing cracks in these materials is possible, although it requires patience and the right techniques.

For minor cracks and surface imperfections, flexible epoxy fillers designed for plastics can be effective. However, it’s crucial to understand that dashboard repair can be challenging, and achieving a factory-fresh look might be difficult, especially for extensive damage. Professionals often recommend simpler and more reliable solutions like installing a vacuum-molded dash cap. These caps are custom-fitted covers that go directly over your existing dashboard, providing a seamless and new appearance.

However, if you’re determined to tackle the repair yourself using epoxy, here’s a step-by-step guide to help you through the process:

DIY Epoxy Repair for Dashboard Cracks

This method utilizes a flexible epoxy designed for plastics, such as SEM Problem Plastic Epoxy, to fill and repair cracks.

1. Prepare the Damaged Area: Begin by carefully trimming or shaving away any loose or lifting edges around the crack. This ensures a smooth surface for the epoxy to adhere to.

2. Apply Epoxy Filler: Using a mixing card or applicator, fill the crack slightly above the surface level with the plastic epoxy. Smooth the epoxy across the crack, ensuring it fills the entire void.

3. Cure Time: Allow the epoxy to cure for approximately one hour. Refer to the product instructions for specific curing times, as these can vary.

4. Initial Sanding: Once cured, use 220 grit wet-or-dry sandpaper to evenly sand down the epoxy. The goal is to level the filled crack with the surrounding dashboard surface. Wet sanding helps to reduce dust and achieve a smoother finish.

5. Repeat Filling and Sanding: Inspect the repaired area. If the surface is not yet level or if the crack is still visible, repeat steps 2-4. Multiple thin layers of epoxy are better than one thick layer for achieving a durable and even repair.

6. Fine Sanding: After achieving a level surface with 220 grit sandpaper, switch to 500 grit wet-or-dry sandpaper. This finer grit will further smooth the repair area and prepare it for texturing and coloring.

7. Texturizing the Repair: Sanding can remove the original dashboard texture. To restore a natural look, you’ll need to re-texture the repaired area.

   • Spray Grain: The easiest method is to use a spray grain texture product, like those used in leather and vinyl repair. Apply in thin coats for best results. apply a spray grain

   • Super Glue Dotting (Alternative): For a more manual approach, you can use tiny dots of super glue. Apply small dots, then immediately pat and disperse them with a paper towel. Catalyze the super glue with baking soda for quick hardening. Sand lightly after curing to even out the texture. demonstrated here For optimal results, follow the super glue method with a spray grain application.

8. Spray Grain Application: Apply the spray grain in several thin coats, allowing each coat to dry for at least 10 minutes before applying the next. Thin coats prevent runs and provide better control over the texture. Gently polish with 500 grit sandpaper between coats if needed to refine the texture.

9. Color Matching and Application: Once the texture is satisfactory, apply color to blend the repaired area with the rest of your dashboard. Shop Our Colors

   • Rub ‘n Restore® Colors: These colors are designed to dry with a low-luster finish, ideal for dashboards to reduce glare. They are self-sealing and generally do not require a separate sealant.

Consider a Dash Cap for Simpler Repair

While epoxy repair is a DIY option, installing a dash cap offers a simpler and often more effective solution, particularly for extensive or multiple cracks. Dash caps provide a full, new surface and eliminate the need for precise color matching and texturing. They are custom molded to fit your specific vehicle model, ensuring a seamless and professional-looking result.
