What is Electrostatic Painting – What Are Its Benefits?

what is Electrostatic Painting

The hassle of the painting process is a struggle that is well known to homeowners, landlords, and their friends and family alike.

Depending on the size of the room, the operation can take a solid chunk of the day or even up to several weeks if the project is large enough.

On top of the time commitment, choosing the right type of paint and paint applying tools is no easy task either – latex and oil-based paints seem to leave all sorts of imperfections from bubbles and can peel, while rollers and brushes, no matter their quality, will tend to leave streaks.

Unsurprisingly, paint innovators have come up with an ingenious solution for these problems by employing electrostatic spray paints to get the job done.

The primary idea behind electrostatic paint is a tried-and-true tactic that also happens to work well in the realm of dating – opposites attract.

In spite of this simplistic idea, electrostatic paints are a bit more complex in reality, have consistently proven to be an effective way to paint without producing flaws like the paints that came before.


What is Electrostatic Painting?


As mentioned before, the electrostatic painting was developed and works because of the adage that “opposites attract”.

This phrase pops up frequently in science classes and is the driving force for describing how magnets work.

The negatively charged molecules of one object, usually metal surfaces and/or metallic substances, are attracted to the positively charged molecules of the magnet.

The resulting interaction has the two pulling objects pulling towards one another to connect with one another.

This is the same exact principle that drives electrostatic paints.


What Does Electrostatic Coating Mean?


The electrostatic spray-paint molecules are positively charged and the molecules that line the wall are relatively negatively charged.

The attraction here is incredibly strong which heavily reduces the likelihood that any sort of bubbles will form, or peeling can occur.

What truly sets electrostatic paints apart is a combination between these attractive qualities and the repulsive qualities between the paint molecules themselves.

Of course, the paint molecules are intrinsically attracted to the wall due to the stark difference between the charge of their molecules.

This enables a strong bond to be formed between the two which creates a smooth, unobstructed surface that looks beautiful compared to traditional paints.

The second aspect of this paint is that since all this electrostatic coating is positively charged, the individual droplets will be propelled away from one another and almost literally seek out the negatively charged surface.

Such attraction prevents the paint from being over sprayed onto certain areas and creates an even coating across the surface.

You’ll still have to ensure you’re pointing the spray gun over a relatively even area yourself, but this process is more or less automatic and can be done with ease.

In the end, the final result will be leagues better than if it were done using normal spray-painting methods.


What are the Benefits of Electrostatic Painting?


There are several other benefits aside from creating a more even surface, though this is a huge benefit in itself.

Regardless, here are some of the other primary reasons that electrostatic painting can be preferable to normal paints and coating processes.

1- Durability

Electrostatically painted surfaces aren’t impervious to damage.

However, they are non-porous, which makes it difficult for other substances to get into and damage the paint itself.

This makes such painted surfaces easy to maintain over their lifespan and can be cleaned off in seconds.

2- Increased Value

Using this type of paint is akin to making an investment that you’ll expect a decent return on investment with.

Electrostatic paints and the accompanying materials are on the expensive side to purchase.

The benefit comes in later because it will ultimately increase the property of the property and/or section being painted.

3- Less Product Lost

Due it the attraction/repulsion aspects of this paint, less paint will need to be used as a result.

Electrostatic paint will work automatically to find sections of the surface that aren’t yet covered instead of piling on to painted areas.

This also produces an even painted surface that looks like it was done by a professional, just without the cost or the same level of effort is necessary.

4- Convenience

Compared to traditional paints, electrostatic paint dries rapidly, poses few health concerns, and is easy to apply even for beginners.

Hence it is best to use for wrought iron fencing, outdoor equipment, antique bathtubs and even your old kitchen appliances like refrigerators or oven.

5- Protection

Along with the convenience, powder coatings provide an ample amount of protection for the surface being painted.

Unlike other paint jobs, electrostatic paints can actually refurbish the surface it’s being applied to.

6- Revitalization

At the end of a surface’s life, it can feel like it will have to be entirely replaced in order to look good again.

Fortunately, these paints essentially subvert the replacement process by making them look good as new once the painting has been completed.


How to Do Electrostatic Spray-Painting at Home?


The electrostatic method of spray painting involves the usage of specialized equipment like an HVLP (High Volume Low Pressure) sprayer gun.

Before spraying any paint on the final surface, makes sure to test your sprayer and the fan pattern.

You will need to turn on the electrostatic and perform the test to ensure the sprayer is spraying the paint as it should.

When consulting a professional painter, it would be rare to find one that goes into a project without a game plan of some sort.

Therefore, for using electrostatic spray paints at home, the same principles must be applied.

A relatively streamlined process looks something like this:

  • Inspect the Surface
  • Mask the Area
  • Ground Metals
  • Apply Paint
  • Clean Masked Area

Once this has been completed, it is advised not to go near the surface for at least 24 hours in order for it to cure.

It may dry faster than this, but this will ensure nothing goes wrong.

Final Thoughts

The electrostatic paint spraying process works so well because of the aspects described before: the paint particles are positively charged and are effortlessly attracted to the negatively charged, grounded surface particles.

The attraction will cause the paint to spread across the surface seamlessly and dries in 24 hours.

In actuality, the electrostatic painting process creates a paint job that encompasses the absolute best outcome for spray paints without any of the messiness that accompanies it.

If you have not tried it yet, you should definitely give it a try when planning your home renovation next time.

Since the process can be complex if you do not have the right knowledge, I recommend getting the help of a professional painter to get the job done right.
