discussion Pesky dust and blowing it away

[BattleshipBob]

Despite my best efforts, dust and tiny hairs usually make a appearance and always after painting!

Can you get a airblowing gun, like the ones I used on trucks to blow dust etc off components etc. Or can a airbrush produce enough air pressure to blow the stuff off??

I would think so Bob, other than that, remove the gun and use the hose, that will blow any dust away.

The little cordless Dspiae vac can also be used as a blower, you fit a small nozzle /tube /hose (included) to the rear exhaust vent and it acts as a nice blower to clear dust, etc. See previous vid I did here....
YT clip on Dspiae vac/blower
Vids only 10 mins long and if you go to the 3min mark I discuss the air blower function.
Cheers

Ta very much, being a Dspiae stalker I have one. I'll give it a go!

A junk or broken airbrush should make a decent blower, I use one that came free with my first compressor.
You may need to crank the pressure up.

Thanks Andy, noticed you can also get battery powered hand held ones, about a tenner?

 

[Andy T]

Something like that might work, but I'm not sure how much puff they have.

 

[BattleshipBob]

This is a typical one Andy

 

[Andy T]

Certainly looks the part Bob but I've no idea how they perform.

Me too, it will blow my wig off or dust of my wallet lol

Musing aloud, I’m not sure blowing dust off is the best idea. Just puts it back in the air so it can land back on the newly sprayed wet paint when the air is pulled back in by suction from the spray booth. Don’t know the answer though, wipe over with a damp brush perhaps?

Tack Cloths are good for dust removal and between sessions model kept in a container.
One of my wife's sealable plastic cake boxes is the latest choice.

I reckon an airbrush with a decent psi could work, plenty of cheapo ones on Amazon.
Don't recommend them for paint though, tried one just out of interest and it was rubbish.

Morning Tim, was thinking that myself? Could possibly blow off dust away from the booth, But have an idea, see below

Hi Leyton

I use tack cloths and yes keep it in a food container as you say. Going to see if I can cut it into strips for small places. Then use with a tweezers?

I did toy with the idea of making a drop down spray booth plastic front curtain to minimise dust ingress while drying. Basically, spray, switch off booth, drop curtain…. However , cleaning the booth properly before spraying probably gives a better result. The dust (dried paint droplets) that collect on the coarse outer filter during use is pretty impressive. I’ve started washing mine every few sessions and giving the housing a wipe with a damp J cloth before use. Helps a bit, but I don’t think this issue is fixable without significant expenditure on pro quality air handling, room HVAC, Laminar flow safety cabinet, specialist clothing and cleaning etc. Certainly not cost effective for making plastic kits….

A valid point Tim - there's no point just blowing the dust somewhere else.

I tend to have my extractor running and aim the dust towards it. Hopefully that should do the trick in getting rid of it.

Also, I only do this for the final bits, before wiping with a tack rag. Any sanding dust gets "swept" from the model with a 1" or 2" paintbrush, straight into the bin, before getting anywhere near the booth.

That's my method but I'm sure there are plenty of others that'll work just as well. As you say though, we can only do so much...

I think the biggest problem is the room is built inside the garage, we all know that garages are a huge dust and general crap centre, and no matter what I do, spiders etc get in, so I regularly hoover. But its a constant battle. I do use the kits box to store the hull and the superstructure bits in sealed food containers. Hopefully the modelling room will cut a lot down. I'll store as much as possible in cupboards etc to keep the dust down.

Hi Tim

I wash the filters too and have ordered 3 new ones as the others are in a sorry state lol. I hoover the booth as well. Do you just use water with the J cloth?

Thinking of buying a Benchvent booth for the long awaited room, 95cm wide so it will take virtually all 1 350 and you can get a hinged door. Not cheap of course but lifetime warranty, metal and high quality.

I know what you mean Bob, my paint jobs are definitely cleaner since moving out of the shed.

There's less spiders in them anyway

 

[Tim Marlow]

My paint jobs are done in a spare bedroom….but I still get dust . I wash my builds in the sink with dish soap before painting. Best way to get rid of finger grease and general swarf.
