Help!!!! paint spraying nightmare
Any paint sprayers out-there I'm having one hell of a nightmare, never ever had this before, HVLP gravity feed gun.
trying to spray nose cone black,high build primer went on OK. trying to get the gloss on is turning out to be a nightmare gloss black cellulose &
standard thinners 50/50 as soon as the paint is hitting nose cone it's developing a milky coloured coating,
rub it down try again with fresh paint same effect, any ideas only thinners I could get on sunday was from a mates workshop which was standard
thinners,is it likely to be the thinners or is there another cause, 50 deg in workshop compressor and filter drained. will it just polish out with
G3.
Many Thanks
Tony

Standard cellulose thinners is good for cleaning spray guns 
You need good anti-bloom premium quality cellulose thinners.

As above - you really need good quality anti bloom thinners thats compatable to the paint. I'd look to get it from the same supplier myself to
ensure its fully compatable.

by no means an expert and I could be well of the mark.
Does you mate use a heated both ? or spary in a warm enviroment ? use profesional compresor / setup ?
When spraying at home I used anti bloom thiners and its somthing to do with the dealing with the moisture in the air / compresor.
I also have a inline moisture - filter drain / presure regulator are you runnning one of these ?
I am sure thst someone who actaully knows will be along shortly but knowing the above might assist.

Anti bloom thinners required but it'll still tend to happen if its damp where your spraying.

Have you got a trap in the line? It sounds like damp in the air. Some fast thinners will help with the flash time but they won't get rid of all
the bloom if it's damp.
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

as above too
loads of moisture in air tanks, has to be filter out, humidity gets increased when the air is compressed. Watch out for cold drafts too, if you can
see mist in the air then try lightly preheating the nosecone with a hair drier before spraying but not after you have sprayed

Old thinners can pick up a bit of moisture in storage too. Not that we use them for spraying but, all of the compressors we use at work have expensive
moisture traps and oil filters (not the usual workshop ones) on them and it is quite surprising what they collect.

Sorry for the thread hijack but guess this is relevant to the rest of the thread - I need a new regulator / moisture trap to suit paint spraying
needs. Any recommendations at all?? I did think about looking at Stafford this weekend with the other favoured option being Machine Mart. Got a nose
cone to spray myself probably next week!!

Cool. I'll take plenty of cash with me then. Does anyone know if you can buy a filter regulator with detachable lubricator at all?? Obviously
dont want a lubricator for spraying but do with general air tools?

bought mine at Aldi but yes I suspect they will have one with an in-line oiler.
Officially i think you are suppose to keep a dry line for Spraying ( only to be used when spaying and your oiler is off) .
Personally I oil any air tool with a drop of oil before I use it. So dont bother filling my inline oiler.
