Airbrush Troubleshooting Guide, Why Doesn't It Work? Demystifying Airbrushes.

[@brohofied2561]

started airbrushing a week ago i got an iwata revolution and i run on all sort of issues X) till i decided to not just clean the needle part and cleaner spraying but open it all up, surprise surprise, there was some gold pigment below the trigger and some dry magenta on the nozzle, opening it up helped me understand more or less how it works so i searched youtube to find more info and found your insightful video, now i really understand how it goes, thanks :)

I appreciate your understanding of mechanical principles because with this knowledge, you explain in a logical procession, the step(s) which must occur sequentially for a system to complete its operational cycle. You never fail to explain a step, which taken as a series of steps, explains how a system completes its operational cycle. Your logic is easily grasped because of your methodical approach. In short, I appreciate your ability to break a system down into easily understandable steps. It is this quality which sets you apart from all others.

Thanks for the basic info. I had trouble ranging from large globs coming out, plugging up and not inserting the needle far enough into the gun.

one last thing I just noticed. I was looking at reviews of the .5 needle and nozzle and saw a few people claiming that the nozzle broke off rendering their G22 useless. they claim to only finger tighten the nozzle. they claim the nozzle they got was just junk. Have you heard of this? now I am concerned about my airbrush, worried that the part my wife order are bad. I am wondering if this happens because of some shady low-quality parts. basically, knock-off parts for a knock-off. I hope I made this clear lol, thanks again for letting me pick your brain. I am very aware that the nozzles are very delicate and need to be treated with extra care.

[@edwardkennedy5680]

Hi Spidiq8 , many thanks for your v prompt reply , your work experience alone , speaks volumes ! I myself worked in Texas as a house painter in the late 60's. Some genius came in using a spray gun kept us going briefly before we folded !😁 This is my spare brush ! When plugged in it sprays air , however on triggering it it sprays liquid . Have tried a trigger from a cheap portable - same result . I'll check but worried about seals etc. As usual , grateful for your advice n help ! Keep safe ! Best Edward

[@spidiq8]

It'll definitely be the air valve, you'll note on your other air comes out when you press the plunger, and paint when you draw back the needle. If the seal is damaged, incorrectly fitted or dirty or dry they can stick and typically stick in the open position. This is a tiny rubber O ring in the air valve which is the bit where your hose connects and the trigger is right above. A very VERY tiny smear of silicone grease on the O ring before refitting will help if it's just a bit dry for example, but emphasis on the very, you don't want any silicone based products mixing with the paint. Stay safe over there.

[@nickrogers3111]

Thanks for the videos, very informative. I been messing with a cheap Chinese Airbrush for weeks. I think from you explanation I finally figured out why I'm getting air but no paint.

The cheap ones can be great but equally if you get a bad one they can be so frustrating if you're new to them. Once you understand how they work and get the hang of them like anything they become easy to diagnose. Good luck with yours and I'm glad the video was useful.

[@spidiq8]

@@nickrogers3111 Best of luck. My very first cheap airbrush worked like a dream from the start, the second one I got had a defect in the nozzle thread and never would seal all the time. This is the real difference between the cheap ones and name brands. Iwats and Badger are my go to recommendations and they're all typically individually checked before leaving the factory.

[@optrirominiluikus]

You're a lifesaver! I had a problem where I got good airflow, and bubbles in the cup when I tried to paint. Opened the airbrush up and cleaned it. Still had good airflow afterwards, but still no water coming through. Opened it up again, and this time I cleaned it out very carefully. Used these tiny rubber toothbrushes to clean out the channel where the teflon seal sits, and now it works! Going to be real careful about cleaning it out after each use from now on, hopefully without having to disassemble it every time.

Hello there what a great and informative video, as many comments have stated i am relatively new to airbrushing and am having trouble with my h&s ultra, i will try some of your advice and see if this works.Also just wanted to say thanks again as airbrushing has a steep learning curve and having such experience available is really helpful. Thanks again.

[@nokiot9]

Greg Watters remove the valve at the base and submerge the entire thing in alcohol 99% or hardware store acetone (mineral spirit). Make sure you pull the needle back too. Also I keep some of it in a needle tip bottle and feed it into the air port in the bottom then screw the valve on and blow air thru it. Doing all that makes sure you get solvent into every single area of it so it can’t clog. I find most issues with mine are caused by clogs.

[@adrianolsen-woodhamwoodtur4980]

Extremely helpful and comprehensive review of how airbrushes work (and don’t work)........many, many thanks. One question, can you explain the different needle/nozzle sizes and their uses?

[@spidiq8]

Absolutely yes. They're simply for the fan size of the spray area, the larger the nozzle the more paint it will deliver allowing you to spray a larger area from a slightly further distance. The downside is that you can do fine lines as easily with a large nozzle. 0.3 is a good compromise for most model kit painting, 0.2 is really only for airbrush artists who need pencil thin detail and 0.5 is perfect if you regularly spray primer, clear coat or very large models.

Especially with regard to cleaning.

[@spidiq8]

Glad you enjoyed it. Hope it's useful for you and re the cheap stuff. The problem isn't that it's no good. Often it is perfectly good but the qc is so hit and miss. The cheap Chinese brush in this video was the first I got and works great. I used it for years before upgrading and still get it out to remind myself it works well for priming etc. Then I bought another which was terrible fitting and wouldn't seal or work correctly. If you're completely new to airbrushing then I'd recommend the compressor no hesitation but something like a NEO as a first brush as they have qc and you know it should be in working order. When you go to the higher Iwata models you'll actually receive a test card they sprayed from your airbrush to check it's functioning.

i appreciate all the tech and it gave me some insight and things to look for. however, u didn't include a siphon type brush. my problem being that while i have good air flow and no clogging in the uptake tube or bottle vent or anywhere in the brush nothing is pulled from the bottle.

[@spidiq8]

With a siphon type the resultant low air pressure passing over the tube allows the paint to flow up it and become atomised and spray, a Venturi effect like in a carburettor. The reasons for no flow are either paint too thick/airflow too low or a combination of both or a blockage. Being sure there's no blockage it has to be one or both of the others. Check that your vent hole is clear if it's a capped jar and the air pressure has to be quite a bit higher to get the same effect from a siphon feed.

[@Moxiltws]

Thank you so much for this video! You're so right about the imortance of understanding how the airbrush works!! I was realy close to just get a new airbrush but I finaly find out what the problem was and it's due to my new understanding of how an airbrush works. I had a really bad case of sputter even when spraying ink. It was not a dilution problem and it's making me crazy. When I saw your video I thought of new things I can try to make the airbrush fonction as intended again. It was a problem of air wich I had no idea could happen. Some paint had cluged the end of the air cap leading to a poor delivery of air flow. It works perfectly now I cleaned it.

@@spidiq8 yes it's been expensive, but I got a nice airbrush, set of tamiya acrylics paints, not all of them, working in getting migs ammo products, ak colors, and well just got 2 more model kits, total of 17 in stash, with many more coming. So yes I'm enjoying it very much. I did realize I have the trouble of losing parts for 1/72 scale kits.

My iwata revolution will spray paint, but it sounds like a machine gun and paint sprays out like that too. Even very thin paints make the machine gun sound. What causes this?

[@spidiq8]

Best guess would be a partial clog. Bent needle tip or split nozzle. If you have a loupe or a good magnifying glass have a good look at your nozzle with the needle inserted to see if there's a split. Check the needle tip for straightness at the same time, if they're both OK. Sit the nozzle components in cellulose/lacquer thinner, wipe the needle with the same stuff until it's squeaky clean. Check it has a little resistance on the Teflon seal in front of the trigger. Adjust that in a little if not. (My other videos on stripping airbrushes cover this) then reassemble making sure the nozzle seats well, (use a dot of beeswax on the threads if necessary) and seat the needle and retry and that should sort it.

Hi Spidiq8, sorted thanks to you ! Even though it wasn't my Iwata , and was still working what was happening was annoying - turns out the little button on the attachment of the hose to the gun was stuck down thus not pushing up on the trigger piece that fits into the trigger hole ! Just finished a camo pattern on a 🐅 finding it hard to a achieve thin lines, pity one cannot purchase a o.3 needle for it or(Iwata Revolution). Again as always appreciate your input ! Best Edward

[@spidiq8]

Good to hear you sorted it. You can get 0.3 needle and nozzle for the Iwata. However I've managed fine lines with the 0.5, if you experiment with thinning the paint a little more and using lower pressures 10 to 15psi and spraying closer you'll be surprised.

@@spidiq8 I usually thin my Tamiya paints by filling bottle to the lip with my home made X20A , will try pulling down the pressure and getting in close to get fine lines . Trying to save 💰 these days ! Thinks and stay safe! Edward

Before Teflon and similar materials were invented, what material would have been used to prevent paint getting into the trigger/air valve area?

[@spidiq8]

Older brushes used rubber seals but solvent based paints would damage these gradually.

[@philraggett4059]

Giday , in regard to enamel / hammertone what type of nozzle / needle would be best , i have a paasche ( a very old one with rubber seals ) that i think i will designate for this as i have new guns for detail . Thank you in advance for a wonderful insight as i found the paasche had a bent needle and was blowing back into the pot . Hope the rubber is ok but will now inquire about teflon seals.

[@spidiq8]

Rubber seals will hold up to harsh solvents for a little while but they'll degrade quite rapidly as they dry out, crack, split and perish. If you can find O rings the same size made of Viton they'll be better. For model paints any nozzle will work, for paints which aren't designated as airbrush use I'd suggest a 0.5mm minimum as often the pigments and such can be much larger and will clog a small nozzle easily.

[@philraggett4059]

@@spidiq8 Yes , i`ve looked into it a bit more and have ordered a 0.5 needle kit , the hobby outlet in the city has O rings . I`ll be using it for steel camera lens external parts and body work so the enamel will be durable .

I hope the time comes when I know half what you do. Very helpful. The paint on my model airplanes after drying has been like sandpaper. Additional coats don't help and varnish will dry looking as bad as the paint. Looking at all you mentioned my airbrush is fine. I may need to thin paint more?? Any help please.

[@spidiq8]

Thank you, very kind words. There's no reason that you couldn't know that and more though. For your specific problem I'm guessing you're using acrylics? These have a tendency to flash off very quickly so you need to shoot them at a lower pressure and if necessary closer to the kit. After your first mist coating you're looking for the paint to start looking 'wet' as it lays down. This is a practice thing, knowing the exact point to say that's enough and move further along, not enough and you get a rough texture and too much you get runs. Where possiblr use the recommended thinners as these often have additives like flow improvers and retarding agents to prevent the paint drying too quickly.

[@spidiq8]

@@skimmer8774 I love enamel paints for spraying and it's unbeatable gloss. The only downside is the smell and long drying times. Honestly acrylics are terrible paints in so many respects but it's not worth the argument or upsetting people who like them. The fact is lacquers and enamels simply work better.

[@davidgriffiths9102]

what about if you press down on the trigger and you have paint coming out when there is only to be air since i have not pulled back the trigger asking for paint

[@spidiq8]

If that happens your needle isn't sealing in the nozzle. It's either not seated correctly, not gripped in the chuck or the needle is bent or nozzle damaged.

[@IcarusIcarus76]

Fantastic video I have a problem with my iwata eclipse HP-CS 0.35mm, when i press down only for air a small amount of paint comes out!!! The air cap and head assembly are well at their posisition, what can go wrong? My needle is not bend , only thing i can think of is about my nozzle but at a first glance seems to be ok and clean

[@spidiq8]

Is this every time you press the trigger down or just after you've finished spraying a piece? If the latter then it could simply be a small amount of paint collecting at the nozzle tip. If it's every time though it has to be that the seal between the needle tip and nozzle isn't perfect. Inspect both with a magnifier to check and check the nozzle with the needle in to see if it's split.

[@nokiot9]

If ur using enamel paints you need a .5 mm needle for coverage. The .35 is for very fine fine detail. Try turning the black knob on ur compressor too. I think clockwise will increase the air pressure.

[@edwardkennedy5680]

Hi Spidiq8 , I hope you are keeping well and surviving these difficult times . You have been a great source of help and good sense in the past in helping me with Airbrushing magic! Question for , my no 2 airbrush ( cheepie) which came with the As 18 compressor is bubbling continuously despite everything it has to be the Nozzle ! I have always cleaned as your video , but see now others say never touch the nozzle and therefore draw needle out backwards - , have ordered a replacement - cheap ! Bubbles are a pain in the tail end ! Will soon find out if that's it ! Best Edward

[@spidiq8]

Hi Edward, apologies for not replying until now. I've heard a few say not to remove the nozzle but if you think logically, why supply a wrench specifically for it and also alternate sizes, also for me, you cannot properly clean without, just take care when refitting.

[@cherylsager9883]

How do you replace those teflon seals when they are buried in the body of the airbrush?

[@richardramey5943]

In using oil paint (house/furniture) it seems I have to thin it down to a point where it's too thin , in order not to have issues or clogs. Thanks for any tips !

[@spidiq8]

For airbrushing oils you need good quality artists oils as they have a very fine pigment. The widest airbrush nozzle you'll typically encounter will be 0.5mm the most common 0.3mm. For rougher cheaper everyday oils like the sets good get for starter painting you'd need a spraygun with a 1.0mm or larger nozzle as they're really designed for brushing.
