A coat of spray paint is a great way to revive wear and tear from hindering the shiny metallic surfaces of metals.

But, experiencing paint chipping off from your concluded painting project can be disheartening. Such experience may discourage you from investing your time on another painting project.

One of the reasons why paint may chip off metal is because it didn’t adhere to the painted surface the way it should.

Let’s learn how to prevent this!

How to Keep Spray Paint from Chipping off Metal

Did you notice some paint chipping off your concluded paint projects? After all that devoted time and effort. Saddening right? I bet you are asking what did you miss out.

The solution to how to keep spray paint from chipping off metal might also lie in the material you used. For example, what type of spray paint did you use? Not all spray paints are suitable for painting metals.

This reason and many others can cause paint from adhering to the metal surface. Hence this causes paint to chip off metal.

Now let’s look at the reasons and the solutions.

Why Sprayed Paint May Chip Off Metal

Reason #1: Improper Surface Preparation

Before painting metal, proper surface preparation goes a long way to guarantee a perfect finish. It also helps paint to adhere to metal surfaces.

The presence of unwanted debris on metal surfaces interferes with the paint bond and may lead to paint chipping off.

Solution: Surface preparation means. Applying the right cleaning procedure until the surface is free of any nastiness (rust, dirt, specks of dust, mold, grease, oil, or debris).

Although the typical go-to surface cleaner is a wet cloth, soap, and water cleaning solution, the choice of clean up solution and materials varies and is dependent on the type and severity of the stains on the surface.

For very stubborn stains, I recommend that you soak and wash your metal for at least 10-15 minutes in a mild soap/water solution. Then rinse thoroughly to remove any residual toxins as this contributes to paint chipping off.

Avoid touching the cleaned up metal surface with bare hands – it leaves grease behind.

You may want to protect your work area from wind, as this may blow more dirt on your already cleaned surface.

Reason #2: Incompatibility between the surface topcoat and the paint

While painting on a metal that is in good shape (without rust), some people sand away the top layers of coats and stop when it reaches its original primer. This method is not wrong, but it might threaten the compatibility between the existing topcoat and the paint.

There are some commercial paints that you can apply directly on any surface. Depending on the type of paint you are using; also, you may still need a compatible spray primer designed for use on metals.

Solution: To avoid incompatibility, perform a test on the existing paint.

I recommend performing a quick sanding rough up technique in an inconspicuous area. Then apply the paint.

After you have completed the metal surface preparation, the sanding, it is vital to remember some pro tips to ensure a paint chip-free finish.

Apply the paint in light coats and layers

Sometimes when painting, to downplay the work time and play a smart one, the temptation might arise to apply thick coats of paint at once. Thick layers of paint coat will cause sloppy paint that may chip off later.

Applying paint in thin/light coats (three coats preferably) will guarantee the best finish and protection on your metal.

Protect it

A good top coat will give your painting job more reliable and durable protection and also a final polished shiny look. Apply topcoat with a good quality brush or spray on it.

Let it cure

Allowing paint to cure is to let the solvent dry off completely before touching. The rate at which paint cures is dependent on the weather. Low humidity equals a faster dry time and vice versa.

Also, the golden principle of applying paint in thin/light layers will determine the dry time. More lightweight paint coats result in faster dry time and vice versa.

A half cured painted job may lead to paint peeling or chipping off.
