Here is a complete guide on how to Fix Bubbles in Spray Paint. Have you ever attempted to give your furniture or walls a fresh coat of paint only to have it come out all bubbly and uneven? It can be frustrating, but don’t worry – there are simple solutions to fix this common problem with spray paint.
Firstly, it’s important to identify the cause of the bubbles. One common reason is spraying too close to the surface, causing the paint to pool and create bubbles. To avoid this, hold the spray paint at least 8-10 inches away from your painting surface. Another cause of bubbles can be due to the weather conditions. If it’s too hot or humid, the paint may dry too quickly, forming bubbles on the surface. In this instance, waiting for cooler weather or working in a shaded area is best to ensure the paint dries evenly.
If you’ve already encountered bubbles in your spray paint, don’t worry – it’s easy to fix. Wait for the paint to dry completely, then gently sand down the bubbly areas with fine-grit sandpaper. Once you’ve smoothed out the surface, you can reapply another coat of paint.
How to Fix Bubbles in Spray Paint: Easy Steps for a Smooth Finish!
Spray painting is a popular way to give furniture, walls, or any other surface a fresh and modern look. However, when bubbles appear in the paint, it can be a frustrating experience. This common issue can ruin the outcome of your project and leave you feeling disappointed. But don’t worry; you can remedy this problem with the right approach and achieve a flawless finish.
Whether you’re a beginner or a seasoned DIY enthusiast, learning how to fix bubbles in your spray paint is essential for achieving professional-looking results. Several factors can cause bubbles in your colour, such as humidity, improper application, or the use of low-quality paint. But with a few simple steps, you can avoid these issues and achieve a smooth, bubble-free finish.
Gather Your Materials
Firstly, you will need sandpaper. The purpose of sandpaper is to smooth out the surface where the bubbles have formed. This will help to create a level surface for the new coat of paint to adhere to. Depending on the severity of the bubbles, you may need to use a lower or higher-grit sandpaper. A fine-grit sandpaper will suffice for minor bubbles, whereas a coarser grit may be required for more giant bubbles.
Secondly, a clean cloth is essential for removing any debris or dust on the surface. Use a clean cloth free from lint or debris that could get caught in the colour.
Thirdly, primer is an essential step in fixing bubbles in spray paint. Primer helps to create a barrier between the surface and the colour, ensuring that the paint adheres effectively and evenly. Primer can also help prevent future bubbles by creating a smooth and stable surface.
Finally, you will need your spray paint. It’s essential to choose a high-quality spray paint that is compatible with the surface you are painting. Read the label carefully to ensure you use the correct paint type for your project.
Sanding Down the Bubbles
When fixing spray paint bubbles, sanding down the bubbled areas is an essential step that cannot be skipped. The bubbles create an uneven surface that needs to be smoothed out before the paint can be reapplied. If this step is neglected, it can result in a bumpy and rough finish that will be unsightly and difficult to correct.
To achieve the best results, using the correct type of sandpaper is essential. This type of sandpaper is gentle enough to avoid further damage to the surface but also strong enough to remove the bubbled areas. It is also important to note that sandpaper with a lower grit number should be avoided, as it can cause deep scratches that may be difficult to remove.
Applying the right amount of pressure is essential when sanding the bubbled areas. Too much stress can further damage the surface, while too little focus may not be enough to remove the bubbles. The key is applying even pressure and working slowly, checking the exterior frequently to remove the bubbles.
Once the bubbled areas have been sanded down, it is essential to clean the surface thoroughly. This will remove any dust and debris accumulated during the sanding process. A damp cloth or sponge can ensure the surface is arid before moving on to the next step.
Cleaning the Surface
One of the most important aspects of surface preparation is effectively removing any dust or debris that may have accumulated after sanding. Sanding is essential in refinishing or painting a surface, as it helps smooth out any rough spots or imperfections. However, it also leaves behind a significant amount of dust and debris, which can compromise the quality of the finish. Therefore, removing this debris before moving on to the next steps in the process is crucial.
Depending on the surface type and available tools and materials, there are several ways to clean a surface after sanding. One standard method is to use a vacuum cleaner or a tack cloth to remove any loose dust or debris. A tack cloth is coated with a sticky substance, which helps pick up and trap any dust or debris left behind after sanding.
Another effective method is using compressed air to blow away dust or debris. This is especially useful for hard-to-reach areas or intricate details that may be difficult to clean with a vacuum or tack cloth. However, it is essential to use caution when using compressed air, as it can be powerful enough to damage the surface if not used correctly.
In addition to removing dust and debris, it is also essential to remove any grease, oil, or other contaminants that may be present on the surface. This can be done using a degreaser or a solvent, depending on the type of contaminant and the surface material.

Applying Primer
The primer’s primary function is to promote better adherence to the topcoat. Applying primer creates a more receptive surface to paint, allowing the coat to bond more effectively. This results in a smoother and more even finish, with no visible brush strokes or roller marks.
Another essential function of primer is to prevent the formation of bubbles. Applying paint directly onto a surface can sometimes react with the material and create bubbles or blisters. This can be especially problematic regarding metal surfaces, as the bubbles can eventually lead to rust and corrosion. Applying primer first creates a barrier that prevents the paint from reacting with the character and causing these problems.
Spray Paint Application
Firstly, it is crucial to maintain an optimal spraying distance from the surface. Holding the spray can too close to the surface can cause the paint to pool and create bubbles, while keeping the can too far away can result in a thin, uneven coat. A good rule of thumb is to have the can approximately 6-8 inches away from the surface, adjusting the distance as necessary depending on the size and shape of the object being painted.
Allow to Dry.
After spraying, let the paint dry completely. This usually takes about 20 minutes. As it dries, the bubbles will get smaller and smaller until they disappear. Drying time is a critical aspect of achieving a flawless finish. If the paint dries too quickly, new tiny bubbles could form as the paint cures.
We want to avoid this, so undisturbing the surface is important until no more changes are seen. Rushing the drying process could also cause cracks or a dull finish. I’d recommend allowing at least 20-30 minutes to be safe. Just set it aside in a dry, well-ventilated area and let the paint do its thing until it feels scorched to the touch before moving on to any next steps. With patience, it will result in a beautiful, bubble-free coating.
Checking for Imperfections
Thorough inspection for remaining bubbles and imperfections is necessary before completing the project. We’ll explain how to identify and address any remaining bubbles, ensuring the final result is smooth and professional-looking.
- Examine it under bright, directional lighting if possible. Natural daylight is ideal. The shadows and angles will help imperfections pop more than typical room lighting.
- Get down on their level – literally. Crouch or lay on the floor/ground to look at it from as flat an angle as possible. Things tend to jump out more when your perspective is shifted.
- Scan slowly. Resist the urge to speed through. Focus on a tiny section at a time and make slow, deliberate passes over the entire surface. Don’t hurry.
- Check for inconsistencies using lighting or shadows as references. Look for uneven shading, smudges, or distortions compared to surrounding areas.
- Look for remaining bubbles. Gently run your fingers over the surface to feel for any raised or squishy spots hiding air pockets.
- When in doubt, spray it with water and watch for beads or streaks. Residual moisture can sometimes reveal defects.
Final Touches
Completing the final touches involves curing the paint to ensure a lasting, durable finish. We’ll discuss the importance of following the manufacturer’s recommendations for curing and how it contributes to the overall quality of the paint job.
Finishing up properly involves giving the paint time to cure fully before subjecting it to wear and tear. When freshly applied, paint isn’t yet set in its hardened, protective state. It’s still soft and vulnerable to damage from moisture, abrasion, chemicals, and more if handled hastily.
Enjoy Your Smooth Finish!
After fixing bubbles in your spray paint, you can now enjoy the satisfying results of your efforts. We’ll discuss the sense of accomplishment of achieving a flawless finish and offer tips for maintaining and preserving the painted surface.
