List Of Common Spray Paint Mistakes
There are several frequent spray paint blunders, and cracking is the most common one. In most cases, insufficient surface preparation is to blame, resulting in weak and ineffective adhesion.
It’s advisable to pay greater attention to your preparations’ details to avoid them crumbling. Before painting a surface, ensure that the surface has been cleaned properly.
If there are any impurities like dirt, oils, or dust present, the paint won’t adhere properly. This will lead to cracking, so take your time and be meticulous while prepping.
- Inadequate surface preparation is the first step in avoiding cracks and other flaws in the final paint finish. Before the new material is applied, the surface should be free of cracks and other flaws.
- When using reducers and hardeners, remember to comply with the manufacturer’s instructions. The final dry paint film might be harmed by using defective or inferior materials.
- The improper reducer may lift an undercoat that appears to be cracking in the final layer or by some materials being top coated before curing fully.
- Defects in the dried paint film can occur if the correct ratio of activator/hardener is not correctly combined or if too much is used.
- If you’re applying and curing your paint at a high temperature or humidity, the surface can develop cracking and other flaws.
- Cracking might occur if too much material is sprayed in completely wet coatings.

This type of paint is called orange peel because it looks like orange peel once it dries, with many small pockmarks. You’ll want to stay away from this because it’s an unflattering appearance. This is a result of overdoing the spray paint and putting too much of it in one coat.
- Applying a lot of paints in wet coatings can result in an excessively thick layer. Before the paint dries, this prevents the paint flow into an even film.
- Negligent application of the reducer might cause the solvents to vaporize too quickly, resulting in an uneven paint coating and a less-than-desirable final appearance. Use the correct reducer for working circumstances and temperature.
- Problems associated with the use of firearms: Spray guns, fluid tips, and air caps should all be used in a precise manner for the task at hand. This can lead to poor atomization of the paint, preventing it from flowing properly. Insufficient air pressure can also cause this problem.
- This is a wrong approach: There are many variables that might cause an orange peel, including the position of a gun tip, speed of a pass, overlap, and distance.
Runs & Drips:
Drips and runs are by far the most prevalent paint problem, but they’re not the only ones. It is possible to make several faults with your technique, but all boil down to over-painting a single region.
Moving slowly, spraying from a minimum distance, or trying to apply a thick coat are all possible causes. Patience is required to avoid drips and runs.
Allow each coat to dry completely before proceeding to the next. Drips and runs are inevitable if you rush and apply a lot of paint at one time.
Running and dripping will continue to plague you if you use improper spraying techniques and move at unpredictable speeds while applying an uneven coat.
Use correct spraying techniques and avoid applying a lot of paint at once to avoid the dripping and splattering you’re now experiencing.
- Choosing the wrong reducer or using too much reducer can significantly impact the final finish. The reducer you choose should be appropriate for the material you’re spraying and the shop circumstances you’ll be spraying in. Two of the most common causes of sags and runs are slow-evaporating reducers and excessive usage of reducers.
- Excessive film thickness causes paint to flow when applied in full wet layers.
- Additionally, not providing enough time for the initial coat’s solvent to flash off might lead to runny paint.
- Paint sags can be caused by a lack of air at the end of your paint gun. Use the right air cap or fluid tip and the right paint gun for the painting material.
- This is a wrong approach: The speed of the pass, the overlap in time among passes, and the distance from the gun panel may be all contributing factors to the runs and sags you see.
Fisheyes are those small, circular blotches that can emerge in your dried paint when you’re not paying attention. Surface flaws or pollutants, such as oil and grime, are to blame.
Make sure your surface is appropriately prepared before painting to avoid problems like fisheyes in the future. If there are any surface flaws, sanding will be your best bet for removing them.
- Immediately after painting, fish eyes may be seen in the finished product. Fish eyes can only arise for one reason: contamination.
- Toxins present on the bottom of the water are responsible for fish eyes. The second most common cause of contamination is during the preparation or painting phase. Due to the lack of oil separator and water and the reuse of shop rags that may have been previously used with silicone or other compounds, this can occur. Because certain silicone and wax products might damage paint, caution should be exercised when using them near a paint shop.

Peeling And Flaking
In the same manner, as cracking is caused by poor preparation, peeling and flaking are also caused by poor preparation. In most cases, grime, dust, or oils are the culprits.
Preparation is the best approach to avoid paint flaking and peeling while it dries, so be sure to do it thoroughly. Make sure your surface is free of any impurities before spraying if you want good adherence.
- If the substrate has not been adequately abraded or has surface irregularities and/or rust spots that have not been removed before painting, delamination may develop. Improper surface preparation. Keep in mind that the surface is only as excellent as the materials used to construct it.
- The thinness of the film is too low: The importance of maintaining a consistent and appropriate film thickness cannot be overstated. When the paint is applied too thinly, it has a propensity to separate from the surface it is applied on.
- Application instructions were not followed: Adhesion may be difficult if the proper application directions are not followed. For example, to avoid delamination, some undercoats should undergo sanding before applying a topcoat.
It’s easy to introduce bubbles while using spray paint if you shake it around too vigorously. Shake the paint well to mix the contents before spraying correctly.
Paint will bubble up if you shake the can too vigorously. After you’ve sprayed the paint, you’ll see these bubbles. In spray paint, bubbles can also occur if you apply them to a porous surface.
Air can be trapped in the pores of porous surfaces. Bubbles might form while the spray paint dries due to the presence of air.
- Outside, it can be very wet. There is a longer drying time for the initial layer of paint in this situation. In other words, it’ll bubble if you start applying a second coat over the wet first paint. There’s a lot of humidity even while you’re spraying in your garage.
- Out there, it’s just too chilly to be outside. For metal surfaces, the temperature outside should be between fifty and ninety-degree temperature. On the other hand, metal retains heat for a more extended period of time than, say, wicker or wood. For this reason, the temperature or the light may have to change.
- It’s also possible that the heat outside is to blame. There are just a few accounts of this; however, you may have heard about it from friends or neighbors. So if possible, avoid spray painting on hot days! Who knows, it might actually work after all.
- Finally, those bubbles have another explanation. To be on the safe side, consider whether you performed cleaning your piece well but did not allow it to dry completely. Keep in mind that the object you intend to paint must be very clean and dry in order to get a smooth, even finish.
Without sufficient time for the paint to completely dry before use, spray paint will become tacky. Having sticky or tacky paint is a sign of moisture in the paint, not the paint itself.
If you put many layers of spray paint, the paint will become tacky and difficult to remove. The longer the paint has to cure between applications, the more is the chance for it to get tacky.
Spray paint can also become tacky if you don’t allow enough time between layers for it to dry completely. If you use low-quality spray paint, you may also end up with a sticky finish.
You should always allow ample drying time between applications of spray paint to prevent it from becoming tacky. Don’t apply a lot of thick coats of spray paint to your vehicle.
- There are a number of typical causes of spray paint sticking, including using wet paint instead of dry paint, utilizing inexpensive spray paint, and oil-based spray paint when the water-based spray paint is the proper choice. Some can be avoided totally depending on the circumstances, while others are simple to solve.
- Even though some of our readers may be dealing with a lot of challenges, most people tend to experience one or two of these issues at a time. It’s still worthwhile to read the rest of the post, even if you think you’ve figured out what’s wrong with your spray paint after looking at our explanations for the various issues.
- However, there are several less common reasons for spray paint being sticky that we don’t expect most of our readers to encounter. Many people find it more challenging to train when they can’t see the paint or the settings in which it was used because it’s more complicated and challenging to assess.

If you’re painting a huge area with spray paint, you’ll likely end up with a blotchy finish. With spray paint, it isn’t easy to attain even coverage; thus, it’s more likely to be blotchy over large areas.
Fine-grit sandpaper should be used to sand the finished coat until it is entirely smooth carefully. To complete the project, a clear coat should be applied.
- One of the most common causes of blotchy spray paint projects is a lack of spray paint experience.
- Everyone has been there at some point. Fast, cool, and a lot of fun: spray-painting painting is more thrilling when you use spray paint. Even while it’s tempting to go with the flow and end up with an uneven paint job, it’s actually relatively simple to correct.
- Blotchy spray paint is blamed mainly on a lack of proficiency in this area. Spray paint container or sprayer mishandling is to blame. Blotchy spray paint is caused by beginner blunders like overspray, halting your spray at the wrong place, or getting too close to the project.
- You can get blotches even if you spray at an excessively steep angle. Blotches can also be caused by factors such as filthy equipment and incorrectly prepared spray paint. This is a good thing because fixing it is a piece of cake.
- Spray paint blotches may be a problem for anyone, so here’s what to do to prevent them from occurring.
During the application of thick coats of paint, wrinkles can emerge. It’s easy to see in the photo how the paint coating shrinks and develops crawling as a result. Letting the undercoat completely dry before applying the final coat can help to avoid this problem.
- The paint can dry on the top, but the paint underneath remains wet. A wrinkled web is formed with each expansion and contraction of the dry layer. When utilizing oil-based coatings, this is more likely because of a thick application.
- Wrinkling can also be caused by immediately exposing a dry water-based paint layer to dew, high humidity, or rain. A large amount of solvent must evaporate before the paint can be considered fully cured. At this point, moisture from the surrounding air might seep back into the coating, causing it to wrinkle and degrade. If you use water-based paints rather than oil-based paints, this problem will likely arise.
- Post to the rapid application of the second coat, wrinkles can form because the first coat has not had the time to dry. The upper coat dries into a film, obstructing the regular drying of the lower coat. This is likewise the case when a topcoat is put before the prep coat is fully cured.
- Severe temperatures can also cause wrinkles. When painting outside in hot weather, it’s possible that the paint will produce dried skin before thoroughly drying. During periods of extreme dryness, the water solvent in water-based paint will be sucked out of the paint, creating impermeable skin.
- Painting over dirt, oil, and wax-contaminated surfaces can also cause wrinkles. They can create the coating to deform and react in regions where they are found.

Quick & Easy Process On How To Fix Common Spray Paint Mistakes
Spray painting mistakes can happen in a variety of ways, but sanding and repainting are the only ways to remedy them. This will necessitate sanding and recoating the problematic regions.
Let’s take a look at all of the stages involved in repairing spray paint problems and transforming a rough coat into a polished finish.
Always Give The Adequate Curing Time
It’s challenging to resist fixing a mistake as soon as you discover it. Impatience will only make the situation worse. Your mistakes must be thoroughly dried before fixing them may begin. Step two can be started after the paint has had enough time to cure.
Proper Wet Sanding A Must
Wet sanding is the next step after the paint has dried thoroughly. Our goal is to get the paint back to a proper starting point so that we can proceed with a new paint job.
A grit number of thousand or higher is ideal for wet or dry sanding applications. Wet sand can be wet in two ways. You can either moisten your sandpaper before using it to sand, or you can wet the surface with a spray bottle before sanding.
You can use it anyway, as long as you don’t overdo it with the water. There is no need to submerge the sandpaper in water completely.
To achieve a perfectly smooth surface, you must sand away all of the flaws. This may necessitate returning to a bare surface. Alternatively, it may only be a matter of sanding off the top coat of paint.
It’s up to you to see how you feel about it. To make it as smooth as possible to the touch, consider sanding it.
Cleaning The Surface
It is imperative that you allow the surface to completely dry after wet sanding. Preparation for the next round begins. To avoid spray paint mishaps, it’s vital to prime our surfaces before applying the paint thoroughly.
It is imperative that the surface be devoid of flaws and spotless. This entire process will have to be repeated if there are any pollutants on the surface that can stop the paint from sticking.
You may use turpentine or rubbing alcohol to ensure that the surface is spotless. Avoid paper towels, which leave too many fibers, by using a rag that does not shed.
Allow the surface to dry completely after washing and priming it, then go to step four.

Apply Primer At The Right Time
If you removed all of the paint and were left with a bare surface throughout the wet sanding process, you’ll want to prime that area so that the paint can adhere and cover evenly.
You may skip this particular step and go straight to the next one for those who have already completed the painting. Be careful to follow the directions on the primer can before using it.
You may spray it on with a can approximately 12 inches away from the surface you’re painting, just like you would a spray paint.
Moving at a reasonable pace from beginning to end, apply paint with even strokes. Prior to applying paint, be sure the priming has completely dried.
Your primer should be the correct consistency if you’re using a sprayer. After that, apply it in broad, even strokes that overlap halfway.
Applying The Paint
If you’ve stripped the old paint off, take the time to clean and prime your wall. When you’re done with that, it’s time to reapply your paint. Before you begin painting, be certain that the surface is completely dry.
Read the directions on the paint can for a place to start. Make sure you adhere to them to the letter. Your paint should be the correct viscosity for your sprayer.
Take long, even strokes with the paintbrush. Allow about 10-12 inches of paint distance between you and your work area. Make sure you don’t overdo it with the paint. Instead, use a very light coat to get the evenest coverage.
Right Amount Of Drying Time
It’s tempting to get eager after painting and try to go forward before the paint has thoroughly dried. However, you must let the paint cure completely before applying any further layers.
Make sure you follow the directions on the paint can. Make sure they tell you the amount of time the paint needs to dry between coats. Before adding more paint, wait a minimum of that long and check to see whether it’s dry first.
Application Of Added Coats
You may need to apply more coats following the correct method in order to complete the process. Once you’ve applied a few even and thin coats of paint to the entire surface, you’re done! If you don’t wait long enough between coats, you could end up with smudged paint.
Mistakes in spraying paint are typical because spray painting requires a fair amount of practice. Using spray paints looks cool and convenient, but it is only possible if you know the proper process for performing so.
However, if you take the time to prepare the surface properly and spray the paint, you can avoid making these blunders and get a perfect finish.
Spray paints are extremely popular and easy to apply only when you are aware of the possible problems and the scenarios that can cause those.
Stain-blocking primers can also help to reduce the risk of these blunders. It is essential to follow the instructions above if you discover any faults while spraying paint.
We have covered everything on how to fix common spray paint mistakes and the reasons behind the same so that you can understand what you must avoid. In case you have fallen into similar problems, here are some easy fixes for you too. All the best.
