Car Paint Looks Like Orange Peel? Here Are the Causes & Solutions

A car paint finish that should be smooth and glossy can sometimes end up with a textured, uneven surface resembling an orange peel. This condition is known as orange peel in car paint. The texture not only affects the appearance of the finish but can also indicate that the material application process was not optimal.

For body repair painters and restoration enthusiasts, understanding the causes and how to prevent it is important for achieving a smoother paint finish.

What Is Orange Peel in Car Paint?

Orange peel is a surface texture that appears uneven, wavy, or similar to the surface of an orange peel. This condition is usually clearly visible when light reflects off the car panel.

During the painting process, this result can be affected by several factors, ranging from spraying technique and spray gun settings to spraying distance and the characteristics of the material being used. Therefore, addressing orange peel cannot rely solely on polishing after the paint has dried.

Causes of Orange Peel When Painting a Car

Orange peel texture on car paint can occur due to several factors during the painting process. The problem does not always originate from the material itself, but can also be influenced by application techniques and environmental conditions during spraying. Some of the most common causes include:

The spray gun is held too far from the surface, causing the material to begin drying before reaching the panel and preventing it from spreading evenly.
The spray gun movement is inconsistent, both in terms of speed and distance, resulting in an uneven coating thickness.
Improper air pressure can lead to suboptimal material atomization and produce coarser droplets.
Material viscosity is too high, making the paint more difficult to flow and level after application.
Choosing the wrong thinner or reducer can affect the evaporation rate and the time available for the material to flow and level.
Environmental conditions, such as temperature and humidity, can also affect the drying process and material characteristics during application.

Therefore, addressing orange peel requires more than simply correcting one factor. Painters need to evaluate the entire process, from material preparation and spray gun settings to spraying technique and the selection of a reducer appropriate for the application conditions.

How Can You Prevent Orange Peel on a Vehicle?

Prevention should begin before the spraying process starts. In addition to ensuring that the panel surface has been properly prepared, painters also need to adjust the application technique according to the characteristics of the material being used. Some factors to consider include:

Set the spray gun correctly, including air pressure, spray pattern, and nozzle size according to the material’s recommendations.
Maintain a consistent spray gun distance to ensure more even material distribution across the panel surface.
Use a stable movement speed and maintain proper overlap between spray passes to prevent excessive buildup or areas that are too thin.
Pay attention to the material mixing ratio according to the technical instructions. A mixture that is too thick or too thin can affect the finishing result.
Choose a thinner or reducer according to the application conditions, particularly when the ambient temperature may affect the material’s evaporation rate.
Make sure the painting area provides suitable conditions, including temperature, humidity, cleanliness, and air circulation.
Do not rush to increase the coating thickness. Allow the appropriate flash time between coats so the material can form the layer properly.

Material selection also plays a role in achieving a smoother finish. A clear coat with good flow and leveling characteristics can help the material flow and even out the surface before it dries. For specific applications, selecting the appropriate reducer can also support this process.

Choose a Clear Coat with Good Flow and Leveling

In addition to spraying technique and reducer selection, the characteristics of the clear coat also affect the quality of the finish. A material with good flow and leveling properties can help produce a more even surface.

One option for refinishing applications is BELKOTE PU 2K Clear Coat 2100. This product is a two-component polyurethane clear coat with high solids and excellent flow & leveling characteristics. It can be used for partial body repairs as well as full-body repainting.

Belkote also recommends using BELKOTE PU Extra Slow Reducer to achieve optimal results from the clear coat.

What If Orange Peel Has Already Occurred?

If an orange peel texture has already formed, the treatment needs to be adjusted according to its severity and the condition of the paint layer. In certain cases, the surface can be leveled through sanding, followed by polishing or refinishing.

However, do not rush into aggressive sanding. Make sure the thickness and condition of the existing layers still allow for correction. Surface preparation is an important part of collision repair work.

In addition to the finishing result, safety during the spraying process should also be a priority. OSHA notes that spray finishing activities can involve various physical and health hazards, so risk controls and appropriate working conditions need to be taken into consideration.

Achieve a Smoother Finish from the Start

Orange peel in car paint is generally not caused by a single factor. Spraying technique, application settings, reducer selection, and the characteristics of the clear coat can all influence the final result.

Therefore, a smooth finish should be achieved from the preparation and application stages, rather than relying solely on corrective processes after the paint has dried.

With the right technique and appropriate material selection, the risk of orange peel can be minimized, resulting in a car body surface that is smoother, glossier, and more professional.
