Why Does Spray Paint Crackle?

Here are some reasons which I have noticed during the course of my painting career. These are the main ones that are the sole reasons for crackling the spray paint. Avoid these in order to prevent the spray paint crackle issue.

Why does spray paint crackle: Because of humidity

During the hot summer months, spray paint tends to become extremely dry and brittle. The paint film dries up and cracks as a result of moisture that evaporates from the paint.

This happens because the paint is composed of several particles of various sizes, each of which is coated by a layer of paint. Want to know the number of cans of spray paint required for shutter painting.

Then, the paint is heated and put into a can along with propellants that cause the paint to spray out of the can. But, the tiny particles of paint are not completely covered by the layers of paint.

When the paint dries, the layer of paint becomes very brittle, and it cracks as a result of moisture. However, it is not advised to spray the paint in the warm months. Here is the complete method to fix paint drips of spray paint. This is the first reason on why does spray paint crackle.

Why does spray paint crackle: Due to the thick layering of paint

“Crackling” occurs in spray paint because the paint is thicker than usual as a result of prior layering. The solution to avoiding this is to apply a fresh coat of paint each time and to paint with a thin layer.

The spray technique to use is: to hold the can 12 to 18 inches away from the work surface, pull the trigger and then quickly stop; this will ensure the paint is applied in a thin layer.

Your goal is to have the paint dry between layers. If the paint isn’t dry, the new layer will sink into the old one and won’t adhere. These were the reasons on why does spray paint crackle.

How to fix spray paint crackle

Wear protective gear before starting

Before you begin to fix a spray paint crack, you will need to put on some protective gear. This includes a respirator, gloves, and protective clothing.

You will also need to make sure that the area you are working in is well-ventilated. Once you have all of your gear on, you can start to repair the crack.

Here is the complete guide after collecting all the tools which are necessary to do this job properly. Follow these steps to do the fixing process completely.

Step 1: Sanding the surface

So here you have a wooden table and it has all these weird bumps on it. To make the surface look even, we are going to take a piece of sandpaper and rub away the rough spots.

The best way is to go over the area in circular motions that cover the length of your table so you don’t miss any spots.

There might be some areas that are too damaged, so just leave them because if you try to smooth them out with the sandpaper there will be nothing left but splinters.

Step 2: Cleaning the surface

To ensure a bright, beautiful finish for your project, first off, you’ll need to start with a clean surface.

Just as sanding creates dust and powdery streaks on the wood, the paint will never stick to a surface that has residual dirt on it.

So, take your time and wipe down all of the dust using a lint-free cloth prior to applying any paint. Only after you’re sure that all the old dust is gone you should proceed to the next step.

Step 3: Priming the surface

A while back, artists would cover their canvases with a layer of primer before they would add any paint.

The reason was simple: it created a slick surface that allowed the paint to stick and stay in place, which avoided chips and cracks.

Because labor and materials are cheaper today, most people don’t bother applying primer when starting an art project these days; however, you can paint two or three times as fast if you take the time to prime your canvas first!

Step 4: Buffing the surface again

Our final tip is only if you’re planning on repainting your furniture in the same color. The way to get the most durable paint possible?

Sand it! This can be a daunting task for some, but we promise you that it will pay off. And also clean the surface after completing

Step 5: Painting the first layer

Before applying the paint, take a screwdriver and poke through the tip of your spray paint can.

In doing so, you’ll be making sure the spray will come out more evenly than it normally would.

After 5 minutes, apply your first coat of paint. The goal is to evenly coat each section of the wall but don’t kill yourself if you see a few areas that are blurred together – we’ll touch it up in the next step when drying time is over.

Step 6: Final coating

There you have it! The final step. We recommend that you apply the final coat just as thinly and evenly as possible to get rid of any remnants of the crackled paint effect.


Spray paint is one of the most beautiful things to customize your objects with. But later you find that the spray paint leaves a very ugly and thick texture on your object, which decreases the original beauty of the object. It looks really ugly and takes a lot of time to clean. It can be really frustrating at times. However, there is a simple way around this. You just need to use a bit of turpentine (or some other wood cleaner) to get rid of the texture. You just have to clean it properly with a brush and turpentine and it will be smooth again. Hope this helps!

First, you need to figure out why it is bubbling. If it is because of the climate, then you will have to get the appropriate weather-resistant spray paint. If the problem is the way improperly you are applying the paint then you will have to learn some techniques. For instance, you need to shake the can well. The can should not be completely empty. Always try to apply the paint in a well-ventilated area. Make sure you apply multiple thin coats for a smoother finish. Thing about the weather; don’t try to use spray paint in cold weather. Try not to get the paint on your skin or on porous materials such as furniture or carpet. If you get paint on your hands, wash them with soap and water immediately.

Spray paint is usually composed of two parts: the paint itself and a solvent. When you spray paint, you’re mixing the solvent with the paint, in order to turn it into a sprayable, useable form. The idea behind the second coat of spray paint is that you are applying a new layer of paint over an existing layer. The reason that your second coat of spray paint is bubbling is that you have extra solvent between the first and second layers of paint. When the solvent in the first layer of paint dries, it will pull the new solvent into the paint. This will create a second layer of paint that is slightly concave. The bubbling is caused by the fact that paint and solvent are not mixing. If you want your second layer to be smooth, you want to make sure that your first layer is very dry. If you used a different brand of spray paint, this may also be the source of your bubbling problem. It’s a good idea to try a few different brands of spray paint if you’re having trouble with second coats.

If you have just finished painting the walls of your house and have noticed overspray, it is easy to clean it. Simply use warm water, white vinegar, and a toothbrush to remove the overspray. You might want to concentrate on the corners and other hard-to-reach areas. Rinse the walls with water and wipe with a soft cloth. This will leave your walls ready for the next coat of paint.

In order to fix blotchy spray paint on metal, you will need to use another spray paint that is of high quality, as well as a good primer and paintbrush. The first thing you should do is to apply the good primer on top of the blotchy spray paint, using your paintbrush. This will help to prevent the blotchy spray paint from rubbing off.

You can polish the blobs away or you can sand them off. The easiest and most effective way to polish away paint blobs is to use a 3M Perfect-It. You can also use a metal paint file, but a Perfect-It will give you a better finish and the metal file can cause the paint to flake off. For sanding, you will need to build up layers of fine sanding paper.
