have bought a cheapee air compressor 24 lt ? capacity 2 hp motor
bought a spray gun for it but the paint only comes out in a 2 or 3 inch spray area is this because the paint is to thick ? have diluted it but then seems to be to thin to cover anything with out 3 or 4 coats and spray seems to be not much bigger lousy directions with it as well
also how do i work out how thick the paint should be ?
looked at another spray gun said low pressure ( from super cheap ) would this work better ? it works ( i think ) on pressure in spray bottle other works buy suction ( i think )

also what about these small hand held air less sprays do they do anything as well as the air compressor types seems (airless ) do have alot more parts to stuff up and clean etc

any info about them would be a great help

The spray gun may have an adjustment nozzle to control spray area?

I can't say I've don tons of heavy duty spraying, but I've done a bit of model spraying with an airbrush and consistency needed is often described as being the consistency of milk to get a good coverage and prevent the gun clogging up or spraying inconsistently etc.

I think the gravity feed cup sprayers are better for smaller compressors?

Hi David
It pays to spend money and get a good spray gun, mine cost about $200.
I've used cheap guns, and they are a pain in the bum.
My gun has 3 adjuster knobs, paint volume, air volume, and spray pattern. Plus nozzle end for horiz, or vert spray pattern.
( I think this is how it all works )
I can get a spray pattern from a couple of inches, to a foot wide.
Paint consinstency plays a major role in how the finish will turn out, with water based I thin with 25-50% water, its all trial and error.
Its always better to put on 3 or 4 light coats, rather than one heavy coat.
I find if the paint is too thick it will come out with blobs in it.
Too thin and it just runs.

Cheers, Allan

I bought a Wagner electric spray gun from Bunnings (on special reduced from $149 to $95) and it is quite good. It is typical German tool quality ie excellent. It takes a bit of practice to get used to doing this. Also I ring the various paint suppliers and ask about diluting specific products. They know about the different guns on the market and can advise about using their products with these. With the flood of cheap compressors on the market I will eventually buy one but probably stick with the Wagner for most things. :)

Hi Rod, I was looking at buying a Wagner myself but somebody advised me that it wouldn't be any good for the large areas I want to do. What do you use your for?

I bought one of the Wagner ones last week as i had a warehouse to paint with ceilings at 3.8mtr then the beams, had great fun using it but the dust it made was something else. took 2 days to do the job and would have taken probably 4 days with a brush due to the type of wall surface. Just used Dulux Proffesional low sheen and diluted it by 10% to 15%.

well bought a wagner as well and worked ok but need the ceiling attachment to do what i want and of course will take a wk to get in joys of little towns

agree dose make a mess i looked like santa after using it for a bout 4 hrs lol
was told to stop using it as soon as it got hot and didnt have any problems with the work load

st5ill would of liked to have the air compressor spray working have been trying to adjust it but still dosent seem to spray much out unless the paint is like water and then need to paint it over againa nd again to get a decent coat

anyway thks
