If your finish starts to look like the surface of an orange, you’re dealing with what’s known as Orange Peel, a common issue that needs to be corrected for a smooth, professional look.

How to fix Orange Peel?

Unfortunately, there’s no quick fix. You’ll need to sand the surface until the texture is completely gone, then reapply the finish. Start with a finer grit sandpaper and work your way up to P400, or follow the manufacturer’s recommendations.

Caution: Avoid sanding down to the bare wood or the seal coat, as this would require extra prep work to start over.

What causes Orange Peel?

Several factors can lead to this textured finish:

• Improper spray gun setup: An incorrect configuration — often too much product for too little air pressure — is a leading cause of orange peel.

  Incorrect viscosity: If the finish is too thick, it won’t atomize properly. Be sure to check the product’s specifications and adjust the dilution as needed.

• Applying too much finish: Less common, but still possible — applying too heavy a coat can create an uneven texture. Always follow the manufacturer’s recommended film thickness, and use a wet film thickness gauge to avoid over-application.

By understanding these causes and how to fix them, you’ll get smoother results and a more professional-looking finish.
