Preventing dust particles from getting onto fresh un-cured paint
Posted by fontuckydick on Wednesday, June 14, 2017 4:35 PM

I have a large scale model I bought years ago. It is a Pocher large scale Rolls Royce kit. I have had to start over twice as far as painting it. Can't do it anymore. Problem: Every time I spray paint, either with a can or air brush, I get dust in the paint before it drys. How do I stop this problem once and for all, thanks.

I place the part in a clean large size plastic tupperware container and place the lid on it as soon as possible.I try to not be outdoors when I paint and I try to have the room or area clean before painting.I use Lacquer as it dries so very quickly before dust has a change to hit.If I do get dust, I wait until the paint is absolutely dry and I polish the area lightly.We ALL get dust!

I use hinged plastic "bins" to store painted projects. I drill holes on each end to allow some air exchange. I drill holes down low on the end of the base and on the opposite end of the lid. If you don't allow for ventilation of solvents they may soften the painted surface of the model as they migrate from the paint but begin to concentrate in the stagnant air in the box. Same as 1:1 paint jobs. Don't trade one problem for another.

I wipe down the body with a tack rag before painting, and it seems to help pretty much as far as not getting dust in my paint jobs.

Okay this, this is going to sound a little off the wall. Back in the day, there was a brief period where I cared about dust particles. What I would do, is go vaccuum the paint room. Then I would turn on the exhaust fan in the paint box (it didn't really qualify as a booth) AND the exhaust in the bathroom around the corner. Then I would spray a heavy mist of water INSIDE a cardboard box, big enough to cover the model and then some. Then I would paint, and use the damp box to cover the model, propping up each corner for air passage. The thoery was, the damp inside of the box would statically attract any dust getting under it before the paint did.

Beleive it or not, I had about an 80% success rate. 

Not long after I started that I discovered and was taught, the fine art of polishing my paint jobs. I still have my old spray box, but no longer turn it on early in hopes of sucking dust from the air in the room. I turn it on, paint right away, and let my paint cure. Then I wet sand (most of the time... sometimes.) with a 3,000 grit sanding sponge. This alone gets me most often to "showroom shine". Then I polish with whatever is appropriate for the paint I used which can get me from the showroom to the show room. 

I guess the bottom line is, unless you have a professional paint booth it's almost always hit or miss. Learn to polish, and stop worrying about a fleck of dust or two. That's my philosophy anyway. Hope this is a help to you.

My favorite color is clear. I am also ambidexterous, I can screw up equally well with either hand. I am 53 years old and been building for most of that time. :)

I use model master enamel.  Two mist coats one wet coat from my Badger 200NH airbrush.  When cured after a few days if there is a spec of dust I have had great success using a run-out of the three Tamiya polishing compounds.  course fine finish, in removing the spec of dust.  I think because the enamel is relatively thicker.
