Hello,

I recently bought another project car, but it has been poorly resprayed quite a few times, so its my turn to do a full respray. My question is, are there any good quality masks for two pack spraying, that aren't air fed? My compressor isn't big enough to supply the gun and a mask with air, so I need one that isn't. And my safety comes before anything else, so i'm not too fussed about cost.

 

Oh, and could I possibly make a home brew air system that is a pipe from outside, that goes to a mask? So it doesn't need the compressor, but is still clean air? Just a thought.

 

i ve used a few of the 3m ones

 

If you can extract the fumes fast do so ie hire buy or beg a extraction fan as no mask will
Cope with the fumes (other than air feed), iv learnt the hard way
An suffer with bad lungs these days

 

As above Mate, the 3m masks will help with particles in the air but airfed mask is the only way to protect from isocyanites.

It has a cumulative effect though, if you painted a bumper with good ventilation and half decent mask you'll be fine, paint a few bodies a week and you'll be done In no time.

A mask with air from outside will work fine too, so long s it has a valve so you don't breath out back up the tube the fresh air comes through cause it'll cause dead air in the pipe and after a few breaths you'll have used the oxygen and will probably go dizzy. Fresh in through tube, out through sides of the mask or summat.

You can't use air from compressor either, unless its properly filtered for breathing. The compressor concentrates anything it breathes in, anything harmful in the air will go in, including oil vapour inside the cylinders etc too.

 

You need to use an air fead mask as nothing else is safe for 2K spraying
the conpressor must be well away from the spray area so it is not sucking in the paint fumes.
I always let all the air out of the conpressor and let it recharge a couple of times to flush it out and let it stand outside in the garden while I am spraying
I'm sure this anoys the nieghbours but I only paint very occasionally
You also need a good water trap/filter and pressure regulator.
It may be hard to justify the cost but if you want to be around for a few more years don't take the risk.We all know people who just use a normal paint mask but they will pay for it in the end.

You need a proper 3 stage filter set comprising of a pre filter, coalescing filter and carbon filter, the carbon one is usually in the airfed mask belt pack. I wouldn't paint 2k without airfed not worth the risk. You can couple 2 compressors if you can borrow one, but if only doing a one off job best to just use 1k paint, I have experimented with iso free 2k primer and it works fine, used standard solvent base coat and upol 1k smart clear not as good as 2k but safer and plenty good enough and reasonably hard wearing.

 

The lad`s at work (industrial painting , bridges) when they cant be bothered or dont have the filter`s use 3M 5255 (what we call monkey mask`s) no fumes through these puppy`s , last for about a month then bin them , i think they are about Ł20`ish from ARCO...

 

spray it outside lol

 

Nonsense advice, there is NO WAY to stop the isocyanites besides breathing fresh air.

A mask can stop particles of paint, but the isocyanite is a gas so unless you're mask is capable of suffocating you, then it isn't stopping it all.

Have a read on how to deal with isocyanite using google or something. It's dangerous in large/frequent amounts. But not instant death.

 

2K paint or clear coat SHOULD only be painted in a booth,

 

Even in a booth you should use an airfed mask. Ideally.
