What Are Tails When Spraying?
Spraying is a common technique used for painting, coating or applying chemicals on various surfaces. It is a quick and efficient way of covering large areas with minimal effort. However, sometimes during the spraying process, you may notice small droplets or lines forming at the end of the spray pattern. These droplets are known as tails, and they can affect the quality of the finished product.
Why Am I Getting Tails When Spraying?
There are several reasons why you might be getting tails when spraying, and identifying the root cause is essential to address the issue. Here are some common reasons why tails occur during spraying:
Incorrect Nozzle Size
One of the most common reasons for tails when spraying is an incorrect nozzle size. If the nozzle is too small, it can create too much pressure, causing the paint or coating to atomize too much, resulting in tails. Conversely, if the nozzle is too large, it won’t provide enough pressure to atomize the paint or coating correctly, resulting in a lack of coverage and tails.
To solve this issue, it is essential to choose the right nozzle size for your application. Check the manufacturer’s recommendations or consult with a professional to ensure you have the correct nozzle.
Improper Spray Technique
Another common cause of tails when spraying is an improper spray technique. If you hold the spray gun too close to the surface or move it too slowly, it can result in tails. Conversely, if you hold the spray gun too far away or move it too quickly, you may not achieve adequate coverage, resulting in a lack of consistency.
To avoid tails caused by improper spray technique, it is essential to maintain a consistent distance from the surface and move the gun at a steady speed. Practice on a test surface to find the ideal distance and speed for your application.
Inconsistent Air Pressure
Inconsistent air pressure is another cause of tails when spraying. If the air pressure is too low, it can cause the droplets to become too large, resulting in tails. Conversely, if the air pressure is too high, it can cause the paint or coating to atomize too much, resulting in tails.
To avoid inconsistent air pressure, ensure that your air compressor is working correctly and set to the recommended pressure for your application. Check for leaks or obstructions in the air hose or gun that may affect the pressure.
Low-Quality Paint or Coating
Using low-quality paint or coating can also contribute to tails when spraying. If the paint or coating is too thin or has not been properly mixed, it can result in poor coverage and tails. Conversely, if the paint or coating is too thick, it can clog the nozzle and cause tails.
To avoid tails caused by low-quality paint or coating, ensure that you are using a high-quality product that is appropriate for your application. Follow the manufacturer’s instructions and mix the paint or coating thoroughly before spraying.
Conclusion
Tails when spraying can be frustrating and affect the quality of your finished product. However, by identifying the root cause and taking appropriate measures, you can avoid tails and achieve a consistent, high-quality finish. Remember to choose the correct nozzle size, maintain a proper spray technique, ensure consistent air pressure, and use high-quality paint or coating for your application. With these tips, you can achieve excellent results every time you spray.

Frequently Asked Questions for Why Am I Getting Tails When Spraying?
1. What are tails in spraying and why am I getting them?
Tails in spraying are the stringy, thin lines that appear in the sprayed paint or finish. They are usually caused by the excessive air pressure or incorrect nozzle size. If you are getting tails, it means there is something wrong with your spraying technique or equipment.
2. How can I prevent getting tails when spraying?
To prevent getting tails when spraying, make sure to adjust your air pressure to the recommended level for your sprayer and paint material. Also, ensure that you are using the correct nozzle size for your paint and surface. It is also important to maintain a consistent distance and angle when spraying.
3. Can using low-quality paint cause tails in spraying?
Yes, using low-quality paint can cause tails in spraying. Paint with a low viscosity, high solids content, or poor flow properties can cause tails to appear. It is important to use high-quality paint that is specifically formulated for spraying to achieve the best results.
4. How can I fix tails in my sprayed finish?
To fix tails in your sprayed finish, you can sand them down after the paint has dried and reapply the finish. However, prevention is key, so it is best to address the issue with your spraying technique or equipment to avoid getting tails in the first place.
