What to Look for Before You Buy Painting Car Air Compressor
Now that you have seen the reviews for the best air compressors around, you should look at some factors before you make your purchase to choose the best compressor for painting. So, we discussed these factors for you.
Air Pressure
The first thing to look for is how much air can your compressor pump out. These values are usually given as PSI or pounds per square inch. This tells you how much force the compressor can deliver from its tank.
Now, if you use an HVLP sprayer, then even a compressor with low PSI should handle the job quite easily as it is all about the volume of air, rather than the pressure. Other than that, if you wish to use this air compressor with other tools as well, don’t forget to check its requirements.
Cubic Feet Per Minute
The next thing to look at is the CFM or Cubic Feet per Minute. This shows you how much air your compressor can blast out while it works. This might seem like a bit too much now, but you’ll need the right equipment to match this number for different kinds of jobs.
Compared to other tools that use air, paint sprayers will work continuously, you’ll need higher CFM ratings to get a more efficient paint job. So, it’s rather essential that your compressor has a good CFM rating for efficient work.
Portability
Now, you also have to look at how easy it is to move your compressor. Small air compressors are easy to move with your hands alone. But large compressors will come with wheels due to their weight. So, unless you have a fixed spot for the compressor, it’s important that you consider this factor before you buy.
This kind of portability will let you keep everything in a compact place and keep things tidy.
Tank Capacity
You also need to look at the size of the tank while buying a compressor to get consistent air power. Car sprayers work with a lot of pressure. So, a small tank won’t do the job that well.
Professionals will recommend a 50-gallon air compressor if you want to get things done efficiently. But you can always make do with a lower volume if it meets the CFM requirements of the sprayer that you’re using.
Noise Made
Now, all air compressors make a whole lot of noise. But it doesn’t hurt to look for one that produces less for the sake of your family and your neighbors. You don’t want to annoy anyone for something that you’re doing, do you?
Moreover, you can also save your ears from all that noise pollution. So, try to buy something that makes fewer decibels of sound.
Oil-Free or Not
And the last thing to look at is if the product’s oil-free or not. This is because oil-free pumps require less lubrication. Now, these pumps come pre-lubricated so you don’t have to worry about oiling anytime soon. So, that brings down the hassle for maintenance.
What Are the Minimum Requirements for an Air Compressor to Paint a Car?
Now that you know about the qualities to look for in your compressor, it’s time we told you about the ideal numbers for the air compressor that you’ll use to paint your car. This might help you decide what is the best air compressor for painting cars for you.
Ideal Air Pressure
The first thing to keep an eye on is the air pressure. To paint a car properly, you’ll need quite the amount of air pressure. Now, the air pressure will vary for different paint coats on the car. But the ideal work range is 15 to 20 PSI. So, keep an eye out for that kind of pressure.
Cubic Feet Per Minute
CFM is very important when it comes to painting cars as you’ll have to apply thin coats as evenly as you can. So, the higher the CFM, the more range you’ll have for your coats.
Hence, you’ll need a substantial air compressor that can deliver the CFM that you need. We would recommend one that can provide 14-18 CFM at 90 PSI.
Best Tank Capacity for Painting Cars
One thing that we would like to mention is that spray painting your car is more about the volume of your air, rather than the air pressure. So, we would recommend an air compressor that has a 30-60 Gallon tank. But, 20 Gallon should also do the trick.
How to Set Up an Air Compressor System for Painting Cars?
Before we tell you how to paint your cars using the air compressor, we need to tell you how you should set it up. The procedure is pretty simple. So, here goes:
Step 1: Check Your Compressor Unit
The first thing that you have to do is check if your compressor unit can provide the PSI and CFM that your spray gun requires. This way there will be no drop in pressure and no loss in volume.
Step 2: Check if Your Air Hose Is the Right Fit for Your Air Compressor
Now, it’s important that you choose the kind of hose that your compressor needs. Otherwise, there might be volume loss and the pressure might drop if the hose is too long. Moreover, the air pressure will be low if your hose is too narrow.
Step 3: Avoid Quick Connectors
If you connect the air hose to a gun, you shouldn’t remove it that much. But some people use quick disconnecting fittings that might end up dropping your pressure. So, we would recommend to not use quick connectors unless you must use them.
Step 4: Get Good Quality Hight Flow Regulator
The next thing that you have to do is get a good air regulator. The regulator makes the air pressure smooth and helps it remain constant. But then again, don’t use a regulator that is too restrictive as it might lead to the pressure dropping excessively.
Step 5: Connect and Start Spraying
Once all that is done, simply attach the spray gun and start working your magic.
How to Use Air Compressors for Painting Cars?
Now let’s see how you can use air compressors to paint your car properly. There are three easy steps that you can use to do so. So here goes:
Step 1: Sand the Surface
At first start by properly sanding the surface of your car. This is necessary to get rid of the old clear coat, the topcoat, and the base coat. Use a sander for this purpose, because you have a lot of ground to cover here.
Try to consistently sand at every point of the surface to smoothly sand off the coats of paint and for the corners and crevices, use your hand for better results. Cover the whole surface as evenly as possible. Once this is done, use a clean rag to apply paint thinner on the surface and wipe off the dust on it.
And lastly, let the thinner evaporate before you start the rest of the work.
Step 2: Prime the Whole Thing
Now mix the primer and the thinner according to the recommended ratios. Fill it into the canister. Then mask all the places that you don’t want to paint. Now, hold the paint gun about 6 inches away from the car panel and spray it side to side. Don’t hold the trigger when not moving the gun to avoid overspray.
Now, make sure you apply the coat evenly and as thin as possible. 2-3 coats should do the trick. After that, sand the surface with 2000 grit sandpaper of the wet and dry kind.
Step 3: Start Painting and Work Your Magic
Once that is done, mix the paint and the thinner. Now, follow the same technique as you did with the primer and apply 3-4 coats of paint. Make sure that you let the paint dry after every coat.
Then sand the surface before the final coat and clean the residue with a clean rag. Now, apply the clear lacquer coat of paint and sand again.
Then remove the masking tape and let the coat cure. With that, you’re done painting your car.
Frequently Asked Questions
Can you paint a car with a 30-gallon air compressor?
Well, you can do that, but it’ll be rather difficult if the compressor has a low PSI and CFM rating.
Can I paint motorcycle parts with a 10-gallon air compressor?
You sure can, just make sure that your PSI and CFM are properly adjusted.
How much air pressure is required to paint a car?
That depends on the kind of work you’re doing. 15 PSI for base coat is fine and 20-25 PSI would be perfect for a clear coat.
Can I use a porter cable pancake air compressor for painting?
You can, but you definitely shouldn’t. These pancake air compressors don’t have enough pressure.
Can you spray interior walls with a car paint gun air compressor?
You can. But these sprays are rather messy and tend to overspray. So, we would recommend you not to do so.
Can I paint a car with Kobalt 8-gallon air compressors?
It’s not ideal to use such a small compressor for painting. But if it’s all you have, you can.
Can a 5-hp 8-gallon air compressor work for painting a car?
The power here is fine, but working with such a small compressor can be difficult when it comes to painting cars.
Can a 20 gallon 2.5-hp air compressor paint a car?
You can do so, but you’ll have to give time for the paint to recover as you keep painting.
Final Words
That was all we had for the best air compressor for painting cars. We hope you could learn something out of here and put it to good use.
Make sure that you consider your use while weighing your choices to make the best decision. Other than that, happy painting!
