What Size Air Compressor Do I Need to Paint a Car?

Best Air Compressor For Painting Cars

Your car painting adventure requires the right air compressor, as any random model will not suffice.

The size is the most crucial factor in picking out the best air compressor for painting cars.

You see, a smaller tank can cause unevenness in the application or force you to stop between coats.

Painting cars is different than other paint jobs as you need a glossy sheen and clear panels.

If your air compressor features a tiny tank, you will have to wait for the tank to refill.

Over-spraying or spraying the same panel multiple times creates unevenness and dullness.

The right air compressor will ensure evenness and a glossy paint job.

These tips will prove helpful:

  • The best air compressor for spray painting features a volume of over 50 gallons, ideally 60 gallons. This volume will ensure your painting job is done in one go. However, as compared to the CFM rating, the volume is a less significant factor.
  • The CFM rating is a crucial factor to consider while determining the right size for your needs. Be sure to examine the CFM output number of all the compressors that you explore. A higher CFM reveals the compressor’s ability to inflate more air. So, a higher CFM will ensure that you can paint your entire car in one go.
  • Purchasing an air compressor with a low CFM rating can create asymmetrical streaks, with some areas glossier than others. It is ideal to choose a CFM rating of 14 to 18 per unit to ensure a smooth DIY car painting job. If you just want to retouch minor areas, a CFM rating of 5 will suffice.

Why Air Pressure Is Important

Air pressure is a vital factor in ensuring you have chosen the best air compressor for car spraying.

The amount of air pressure is indicated by the PSI (pounds per square inch).

People often confuse a higher PSI rating with smoothness, but that’s not true.

It is wise to purchase spray guns with a high volume low pressure (HVLP) to avoid exerting excessive pressure.

An HVLP compressor doesn’t require too much air pressure to ensure the desired results.

It is ideal to use 10-15 PSI while using an HVLP spray gun on the base coat. A 20-25 PSI is well-suited to spray a glossy coat.

Even if you’re using a non-HVLP air compressor, the ratings aren’t very different.

Avoid increasing the PSI reading excessively high while working with a low-volume and low-pressure spray.

Even the most challenging car painting job doesn’t require more than 90 PSI.

The size of the air compressor will determine the effectiveness of your investment and your convenience.

The size also takes into account other factors, such as the CFM and PSI ratings and the technology used to power it.

It is ideal to choose an air compressor featuring a 60-gallon tank, 5-6 horsepower compressor, 14-18 CFM, and 90 PSI.

If you’re choosing a smaller tank, you might not encounter any challenges with the base coat.

But the clear coat staged will prove difficult, and you’re likely to end up over spraying.

FAQ

How many CFM do I need to paint a car?

A CFM (cubic feet per minute) rating is a vital consideration to ensure you’re equipped with the best compressor for spray painting.

Choosing the right CFM to paint your car can prove challenging and complicated, especially for first-timers.

You see, a higher CFM rating reveals that the air compressor is capable of inflating more air, based on the PSI rating.

You will need a higher CFM rating if you are looking for air compressors for painting cars in one go, in simpler words.

This doesn’t take into account the running time you need to get the job done.

However, a low CFM rating can lead to numerous troubles and inconveniences.

A low CFM rating can cause unevenness with bad splotches on one side and neat strokes on the other.

To achieve the most desirable car painting results, invest in an air compressor with a CFM rating of 14-18 per unit.

This will ensure excellence.

However, it will increase the overall cost of your unit. If you need to do a minor retouching, a CFM rating of 5 will suffice beautifully.

What PSI should I use to paint a car?

It is advisable to aim for a higher PSI rating, at least 90 PSI, to enjoy the ultimate convenience and efficiency.

However, it is vital to examine the PSI rating in conjunction with the CFM rating for an enhanced application.

What Spray Gun To Use To Paint A Car?

If you can get your hands on one, you should use an HVLP spray gun to paint your car.

An HVLP (high volume low pressure) spray gun.

They will get the job done quicker with less paint and also spray the car much more evenly, especially on the first clear coat. They also offer some health benefits.

The good news is that these added benefits of using HVLP spray guns will cost you very little.

You can pick up decent HVLP spray guns for $30-$50.

Of course, if you are doing this professionally or you plan to then there are much better paint sprayers available.

Can you paint a car with a 21-gallon air compressor?

A 21-gallon air compressor ranks as a small compressor, but it will get the job done.

However, a smaller compressor with a 21-gallon tank will not prove an efficient and convenient investment for bigger jobs.

If you want to paint the entire go, you will have to do so in parts with multiple breaks.

You see, the air compressor will need short recovery periods in between takes to cool down and dissipate heat.

You will have to wait between different strokes, which will make the paint job uneven and dull.

Yes, it is possible to answer the question, but it will require a lot of patience, time, and effort.

It is pertinent to mention here that the CFM is much more important than the gallons of the air tank.

It is always easier to work with an air compressor tank with ample reserve, but the CFM is a dynamic factor.

A higher CFM can overshadow less air reserve by delivering superior efficiency.

Can you paint a car with a 30-gallon air compressor?

A 30-gallon air tank capacity is an ideal choice while choosing an air compressor for auto body painting.

If you’re investing for at-home usage, you don’t need a tank with higher capacity.

It is wise to focus more on the CFM (cubic feet per minute) so you can enjoy efficiency.

At-home applications do not require large reserves as that is a requirement for auto repair shops and commercial applications.


Conclusion

Choosing the best air compressor for painting cars may seem like a challenging investment for a first-timer.

But as long as you stay focused on the elements of PSI, size, and CFM rating, you’ll find it easier to review different units.

It is vital to align your purchase with your requirements, paint job complexity, and budget.
