The orange peel effect in paint refers to a textured, uneven surface that resembles the skin of an orange. Various factors contribute to this effect, including improper application techniques and environmental conditions. It is commonly seen in applications such as cars, walls, ceilings, cabinetry, and metal equipment and parts.
The orange peel effect in paint is caused by several factors, including application technique, environmental conditions, equipment settings, and more.
Here’s an image of the orange peel texture for reference:
Holding the spray gun at an angle other than perpendicular to the surface can lead to uneven application, increasing the risk of the orange peel texture. Ensuring a consistent and proper spraying angle helps maintain an even finish. Applying the correct amount of pressure is also essential for an optimal finish.
Regulating equipment pressure, product flow rate, and fan pattern is essential to ensure correct and uniform paint spraying, reducing the risk of an uneven finish.
The use of old or damaged painting tools can lead to inconsistent results due to a malfunction in the middle of the painting process. Always make sure that the painting tools are in good condition before painting.
A paint mixture with excessive viscosity will result in an irregular surface. Increasing the percentage of thinner in the mixture helps achieve the right consistency for a smooth finish.
High humidity can slow down drying times, while low humidity can cause the paint to dry too quickly. Both conditions increase the likelihood of an orange peel effect, making it important to paint in moderate humidity levels. In addition to that, when it is too hot or too cold, paint might solidify unevenly, leading to texture issues.
Selecting the appropriate catalyst or solvent with the correct drying speed for your environmental conditions ensures optimal results.
Failing to allow base coats to dry fully before applying additional layers can lead to uneven paint application. Always adhere to the specified drying times for each coat.
Applying too much paint per coat results in an uneven surface and increases the likelihood of an orange peel texture. Proper control of the amount of paint used is crucial for a smooth finish.
To achieve a uniform surface, it is essential to properly prepare and sand the priming coats before applying paint. Poor surface preparation can contribute to texture inconsistencies.
Here are some guidelines on how to fix the orange peel effect in a couple of different scenarios.
Below are some steps you can take to fix orange peel in auto paint.
1. Sand the Surface - Start with a medium-cut product to see if the issue can be corrected without excessive abrasion. If necessary, gradually use more aggressive sanding techniques. Wet sanding is the most commonly used approach. Use masking tape to protect undamaged areas.
2. Cleaning and Degreasing the Surface - After sanding, remove dust and debris using a degreaser and a microfiber cloth.
3. Polishing and Shining - Perform a polishing procedure to smooth out any scratches left. Finally, clean the area with a soft cloth to check the results.
4. Repainting (If Necessary) - If the orange peel defect persists in the finish, restart the painting process. Sand the surface with the appropriate abrasive paper, remove any dust or residue, and apply the finishing coat while following the best practices highlighted above for optimal results. To ensure a flawless finish, consider hiring a professional.
Here is a quick guide on how to fix orange peel on walls and ceilings:
Preventing the orange peel effect requires following certain practices when painting a metal part, a car, or a wall.
● Ensure Proper Technique - Practice your painting and texturing technique to maintain consistency and accuracy. If you are using painting machines, make sure that they are properly aligned.
● Test Your Equipment - Verify that your painting tools are functioning properly to prevent malfunctions that could disrupt the process.
● Plan Ahead - Use materials suited to the temperature and humidity of your workspace to ensure an optimal paint application and drying conditions.
● Prepare the Surface - Ensure the surface is smooth, clean, and free of dust or dirt. Sanding and cleaning may be necessary for an optimal finish.
For consumers, the simplest way to measure orange peel in paint is by visual inspection, but for manufacturers and companies that require a more precise and objective approach, specialized methods are available.
One common method involves using orange peel standards with different degrees of orange peel. By comparing a painted surface to these panels, businesses can determine whether the texture falls within an acceptable range for their application. This approach ensures consistency and quality control in production.

Another advanced method involves using special scanners that analyze the wavy patterns on a painted surface to provide accurate measurements. While highly efficient, these scanners may struggle with smaller parts, making orange peel standards the preferred choice for measuring orange peel for these particular applications.
It is important to note that the acceptable level of orange peel in painting varies by industry and application, as some products require a smoother finish than others.
The orange peel effect is commonly found in industries such as automotive and housing, but it can also be present in many other applications, such as cabinetry and metal parts.
In the automotive sector, it often appears on hand-painted cars, whether applied by manufacturers or body shops. In this industry, the effect is generally undesirable, as a smooth, flawless finish is preferred for aesthetic and quality reasons.
In house painting, this effect can occur on walls and ceilings. While it is sometimes seen as a flaw, certain applications intentionally use this texture for its unique look and ability to mask surface imperfections.

Yes, orange peel in painting can be corrected through proper sanding, cleaning, and polishing techniques. If the defect persists even after sanding and polishing, it may be necessary to restart the painting process.
Orange peel is generally considered a defect in the finish of painted metal components, automotive parts, or other surfaces. While it does not change or disappear on its own, it is not permanent and can be removed through corrective processes. In some cases, it is better to repaint the surface.
Manufacturers can measure the level of orange peel by using orange peel standards to visually compare surface textures. Additionally, specialized scanners are available to analyze the waviness of a painted surface and provide objective measurements. However, these scanners may not be ideal for small parts or components, making standards such as those offered by ACT a more practical option in such cases.
Orange peel in factory-painted cars results from how the paint is applied and the environmental conditions during the drying process. Manufacturers follow industry standards for acceptable levels of orange peel, which can vary between models. More affordable vehicles may have a more noticeable texture, while premium models often receive a smoother, high-quality finish.
