How to Sand Chrome for Paint

Chrome is a popular finish that is often found on car parts, motorcycles, and household fixtures. While it provides a shiny and durable surface, there may come a time when you want to paint over it to change the look or cover up imperfections. However, painting over chrome can be a challenge as it does not adhere well to most paints. The key to successfully painting over chrome is to sand it down to create a rough surface that the paint can adhere to. In this article, we will guide you through the process of sanding chrome for paint and answer some frequently asked questions about this topic.

Materials You Will Need:

– Safety goggles
– Dust mask
– Sandpaper (various grits: 220, 400, 600, 800, 1000)
– Sanding block or power sander
– Water
– Dish soap
– Clean cloth
– Primer
– Paint

Step 1: Prepare the Work Area

Before you begin sanding, it is important to prepare the work area. Start by ensuring good ventilation and wearing protective goggles and a dust mask to shield yourself from any debris or fumes. Lay down a drop cloth or newspapers to catch any sanding dust and protect the surrounding area.

Step 2: Clean the Chrome Surface

Thoroughly clean the chrome surface with warm water and dish soap. This will remove any dirt, oil, or grease that may prevent the sandpaper from properly gripping the chrome. Rinse the surface well and dry it with a clean cloth.

Step 3: Start Sanding

Begin by sanding the chrome surface with 220-grit sandpaper. Use a sanding block or a power sander for larger areas to ensure even pressure and consistent results. Sand in a circular motion, applying moderate pressure. The aim is to create tiny scratches on the chrome surface to allow the paint to adhere better. Once the surface is evenly scratched, move on to the next finer grit of sandpaper (e.g., 400).

Step 4: Progressively Use Finer Grit Sandpapers

Continue sanding with progressively finer grit sandpapers (e.g., 600, 800, and 1000) until the chrome surface feels smooth to the touch. Be sure to remove all visible scratches from the previous grit before moving on to the next one. This step is crucial for achieving a smooth and flawless paint finish.

Step 5: Clean the Surface Again

After sanding, clean the surface once again to remove any sanding dust. Use a clean cloth and water to wipe away all debris and let it dry completely before proceeding.

Step 6: Apply Primer and Paint

Apply a coat of primer specifically designed for chrome surfaces. Follow the instructions on the primer for the best results. Once the primer is dry, you can apply your desired paint color. Use multiple thin coats, allowing each coat to dry before applying the next. This will result in a more even and professional-looking finish.


Q: Can I skip sanding and just use a chrome paint?

A: While chrome paint is available, it does not provide the same level of durability and adhesion as sanding and using regular paint. Sanding is crucial to create a rough surface for the paint to adhere to.

Q: Can I use an electric sander for the sanding process?

A: Yes, an electric sander can be used for larger areas. However, be cautious not to apply too much pressure or leave it in one spot for too long, as it may damage the chrome surface.

Q: Can I wet sand chrome?

A: Wet sanding can be done on chrome surfaces. Simply soak the sandpaper in water and proceed with the sanding process as described above. Wet sanding helps to reduce friction, keeping the surface cooler and preventing clogging.
