Sandblaster compressor used for painting?

Hello all. I am thinking about painting my truck. I have done a lot of research online, and read a few books about painting and think I am ready to give it a shot. I had a question about the compressor I plan to use though.

My friends dad owns a sandblasting business and they use large diesel compressors for heavy duty sandblasting. I figured that they would provide plenty of CFM for painting but wondered if there would be any issues with using this type of compressor. Would I be okay with just using a regulator/filter to bring the PSI down to the recommended level? Would a compressor that large be pushing out too much CFM (is that possible) for the paint gun?

Any thoughts?

Also, any thoughts on the brand of paint? I plan on using a urethane based paint but what would you all recommend?

Thanks for the info.

Dylan.

Regulator

I dunno just how your dads compressors are setup but the ones we used for our jackhammers and pavement breakers put out 125 cfm and they did have provision made for using small tools by have ing a seperate regulator and connection for that..maybe your dads compressor has the same thing or one may be installed..

I woudl definetely spring for a filter regulator to mount on the garage wall..then run a line to the filter regulator from the compressor and then run a whip to your gun from the filter regulator..

Lot of the guys here are using the SPI products for primers and clears..Not sure on the base colors as Spi only has a few colors available at this time..

Those "big ole" jackhammer compressors do indeed put out oil and other junk so if you use it keep that in mind and deal with it before attempting to spray paint.

They put out oil and junk into the compressed air stream? Hmm. Just to be sure we are talking about the same thing, this is basically a 6cyl diesel engine turning a compressor.

Is there any type of filter that will seperate the oil and junk out of the airstream? My only other alternative is the buy a compressor which will add a good 400-500 (at least) to the cost of the job.

I guess when one considers the sheer volume of air supplied by those things it's not surprising that a significant(at least to cause paint problems)amount of oil will be produced. If that thing has a tap for a smaller hose you could probably hook up a good filter and regulator at that point but a water separator should be used some where downstream in the line and not at the compressor itself and then a final in-line disposable filter should take care of it. After you get everything in place it might be a good idea to run it a while to make sure you have the oil and water under control before risking your paint.
good luck

If it is a newer compressor eg; Ingersol Rand 185 it'll work.Its a dry system. But if it is an older model stay away. To be on the safe side go to your local rental shop and rent a 5hp gas pwd. compressor. It'll work just fine. Use a water separator and either empty it every time you fill your gun or leave it open a crack so it'll drain all the time. Good Luck. Cheers!!

Put a good watertrap and oil seperator inline and it'll work just fine. Most good sandblasting setups have a water seperator already built in so just plumb your air line after that if possible and add the extra seperators downstream. A desicant hose is also only about $15 and will add some extra guard against moisture. Just make sure your compressor intake isn't taking in any of the diesel exhaust.
Many years ago I used a 4 cylinder powered gas compressor to paint cars in a barn on the side, the thing was so old you had to start it with a hand crank on the crankshaft snout like a model T, it ran so hot that water in the line was a major pain...but I made it work. Bob

compressor oil and paint

All compressor put out oil downstream- even oil free compressors can because of the oil vapors in the air. As previously recommended, put a filter to catch the oil, and a desiccant filter to catch the water. Water will cause you the most problems, as the heat of compression is carried in the air, and as the air cools, you will get condensation. Condensation can ruin any paint job
