Paint Runs After Spraying – What Causes them?

Paint runs are one of the most common problems that people face while painting their cars, furniture or any other object. They are a result of excessive application of paint in one area, which makes it drip down and create an uneven surface. These drips or runs can be caused by various factors like improper technique, using the wrong type of paint, improper equipment or environmental factors like humidity and temperature.

How to Fix Paint Runs After Spraying?

If you are facing the problem of paint runs after spraying, the good news is that it is not something that cannot be fixed. Here are some steps that you can follow to fix paint runs and achieve a smooth and even finish.

Sand the Surface: The first step to fix paint runs is to sand the surface. You can use a sandpaper with a 220-grit or higher to sand down the runs. Sanding will help you remove the excess paint and create a smooth surface.

Fill the Gaps: After sanding the surface, you may notice some gaps or holes in the paint. You can fill these gaps with some auto body filler or wood filler depending on the surface you are painting. Use a putty knife to apply the filler and let it dry completely before sanding it down.
Sand Again: Once the filler is dry, sand it again to create a smooth surface. Use a sandpaper with a 320-grit or higher to sand the surface. Make sure that you sand the surface evenly to avoid any further runs or drips.
Reapply the Paint: After sanding the surface, it is time to reapply the paint. Make sure that you use the correct type of paint for the surface you are painting. Apply the paint in thin layers to avoid any runs. You can use a spray gun or a paint roller to apply the paint.

Sand and Polish: After the paint has dried, sand the surface again with a 1500-grit sandpaper. This will help you remove any imperfections and create a smooth surface. Finally, polish the surface with some wax or polish to give it a shiny finish.

Preventing Paint Runs:

While fixing paint runs is possible, it is always better to prevent them in the first place. Here are some tips that can help you prevent paint runs.

Use the Right Equipment: Make sure that you use the right equipment like paint guns, sprayers or rollers for the type of paint you are using. Using the wrong equipment can lead to uneven application and paint runs.

Practice Proper Technique: Use the right technique while painting. Make sure that you apply the paint in thin layers and avoid overloading the surface with paint.
Check the Environment: The environment can also affect the quality of your paint job. Make sure that you paint in a well-ventilated area and avoid painting when the humidity is high or when the temperature is too low.
Follow the Manufacturer’s Instructions: Always follow the manufacturer’s instructions when it comes to mixing and applying the paint. This will help you achieve the best results and prevent any paint runs.
