Posted: Sun Sep 30, 2007 1:05 pm Post subject: HVLP Questions

I went "shopping" at Sears yesterday to look at spray guns to use for 

priming parts (did not buy one, but bought their 24" digital level with 

laser -- on sale for $44!!).  They had 2 regular guns and one HVLP gun.  

My question:  does this HVLP gun get used with my regular air compressor 

or would I need to buy a special air supply system?  I didn't see 

anything at Sears that looked like anything other than standard air 

compressors.  If the HVLP cannot be used with my regular compressor, I 

will get a regular gun.  Is there anything special I should look for?  

What other stuff will I need?  I do have a small water separator on the 

output of my compressor and no inline oilers of any kind.  Never painted 

with anything but a spray bomb from Wal Mart

An HVLP gun can be used with a regular compressor. 



Here a couple of good links:

Bob,

All I use any more is HVLP.  It's the BOMB!  Less, way less, overspray, and 

using a lot less material-saves$$$$$.

1) any good single stage or 2 stage air compressor will work.  Any brand.  I 

would suggest that if you have space and $ invest in a good stand up 

compressor.  Sears is ok but over priced.  If you have a Tractor Supply Co. 

near look there.  If not any good discount place, home depot, Lowe's will 

have 30-80 gallon size.  CFM is the number that you are looking for on the 

compressor.  Higher the better.  My IR is 80 gallon single stage 18.1CFM 

5HP - works like a mule.  It will also keep up with ANY air tool that you 

have, die grinder, cut off tool, sanders,  NOTHING can bog it down.

2) Invest in a good quality HVLP gun.  It makes all the difference in the 

world.  DeVilbiss is all that I use.  AKZO epoxy primer, basecoat, 

clearcoat, will handle it all.  Gravity fed(cup on top) or pot feed is the 

only way to go.  Got mine on Ebay, new, half price what I could get it for 

locally.  On Ebay search HVLP paint gun, Devilbiss, there are quite a few 

west coast reputable companies out there that have tons of stuff and great 

price.  Like with anything - SHOP till you drop before laying out the $ . 

You'll get a better product for your bucks.

3).   I picked up the digital level/laser also-mine was craftsman's club no 

brainer.  check out there 3D laser level with stands for $40 when on sale. 

Very easy to stripe an a/c the entire length on both sides with two, or to 

do checkerboard on cowl/spinner/rudder.

Hope that this all helped,

PS - MUST have an inline water trap/filter with any compressor, big or 

small, compressed air makes water and will ruin your tools and paint.  You 

are right-no inline oiler.

Scott,

Glad that I could help out.  One thing that is Critical to the life of any 

HVLP gun is to clean it immediately after use.  I buy 5 gal cans of lacquer 

thinner at a discount paint shop/auto body shop and run 3x 1/2 cups of 

lacquer thinner through it after each use.  Thoroughly wipe out the cup with 

a clean paper towel soaked in lacquer thinner and the nozzle.  Let it air 

dry before putting it away.  If you maintain your equipment, it will last 

forever.  I have one HVLP gun that is 3 years old and shoots as good as day 

one.  The outside ain't so pretty but the guts are spotless.  Most people 

don't take care of their guns properly and then cuss them when they fail. 

Also you can plumb your shop with HIGH pressure PVC pipe and not cast iron, 

same isle as the regular PVC water pipe, just look for High Pressure 

HOT/COLD on the PVC.  Regular or High PVC cement.

Good luck,

Mike H 9A, 8A

If you use PVC, I would make sure your compressor is shut off after every use.  Good practice either way.  PVC will work but it will also become brittle over time and can shatter with a solid hit from something.  If it's permanent, use type L copper pipe.  It's more expensive but will last forever.  It's also rated for compressed air.

All good advice.  I have no plans to plumb my shop with air though.  I 

just drag the air hose around to where I need it...

My last shop was plumbed with high pressure pvc pipe and I did have a blow

out.  I was in the shop when it happened and it took a few years off my

life.  Shrapnel was everywhere and damaged a couple of things but nothing

major.  If anyone wants to plumb the shop I would recommend this product:



http://nibco.com/cms.do?id &pId=14



It is PVC and rated for compressed air.  It isn't quite as cheap as regular

o'l pvc but still not bad and glues together the same.  It is green and they

have great fittings for doing air.  I used it and had T fittings pointing up

for each drop.  Then they have a 180 degree short bend that allows you to go

from the T fitting down to your coupling.  This is great because any water

in your pipe is not dropped to your fittings but rather continues down the

run to the end where you can place a separator.



Good stuff and much safer.

Just for clarification, this stuff looks to be ABS and not PVC.
