HVLP Gravity Feed Spray Gun for water base paint

I have been making up a couple of computer stands out of MDF for my wife.

She wanted one for the laptop at home & another for the laptop at work.

She works in a Real Estate office & that one needs to be very tidy.

I used a 4in1 water based primer/sealer/undercoat applied with a brush & it looked fairly ordinary so I thought I'd try spraying it.

I have a kit of 3 guns I got from Super Cheap Auto a while back & there is one with a 1.7mm nozzle so I dug it out & gave it a try.

Impressive results. :2tsup:

I gave it a couple of coats of the 4in1 while I was working out the best settings.

Then moved on to a 80% gloss Water based Enamel.

Waahoo, am I sold on that, suddenly I like painting. :D

Here is a tip... set your regulator to about 35-40psi with a blower nozzle before you connect up the spray gun, they don't like high pressure at all.

Cheers for the write up Cliff, I've been interested in getting into using spray guns but a bit intimidated. What sort of compressor are you running?

I am also keen to get details. Did you thin the paint or use straight from the can?

I went that way initially then upgraded to a detail / touch up gun for spraying NC lacquer - a Star S-106-TG is the equivalent now I think. Much more refined to use than the SCA units but it comes at a price though.

I have a big 2 cylinder job I got from a friend, I'll check the details later.
I have the regulator on it set at about 90psi which is about right for my Brad Gun.
I sits down one end of my shed with a long air hose that I can drag all around the shed.
I then have a 2nd receiver which is the tank off an old compressor that I bough for $30.
It has a 2nd regulator on the outlet & that is set to 35-40psi.
I have a shorter air hose that runs from that unit to the gun.
The 2 tank system with a long hose in between give the compressed air a better chance of cooling & the moisture then condenses out so I have much drier air at the gun.
Not that it maters that much if you are using water based paint.

I started out thinning it but then I found that I didn't need to with the 1.7mm nozzle.

I had an old saw buck made of ply that is fairly beat up, I used it as the tester to get the settings right before I turned the gun on the good piece.

The saw buck is looking really flash now.

I have one of those too but the nozzle is too fine for water based paint.

Agreed, performance is all in the nozzle size and setup.

G'day Cliff,

Are the guns marked as HLVP, are they gravity fed or pot?

Any clogging of the nozzle?

The guns are marked as HLVP, they are gravity fed.

I didn't have any clogging using straight Water Based Enamel through the 1.7mm nozzle.

I have this kit before they were branded Blackridge. The body of the guns I have are blue.

Thanks for that.

I was not being obtuse asking about the HLVP, have seen claims on the packaging before as to HLVP but the product itself wasn't.
