Protection using iso-cyanates.
 

I'm an occasional painter - garage style. I've done a few day classes, and painted a few panels.

But I'd like to use paints with hardeners, iso-cyanates in other words. And epoxy primers. I can paint outdoors so I don't need absolute protection.

What do you guys use or think of as being an acceptable minimum for an air feed respirator setup. I had been considering a second hand 3M Dustmaster and having the box upwind (or outside of the garage) and a longer air tube.

I like that idea. For occasional use, it'd probably be fine. I wouldn't clear an entire car with that setup, but for limited exposure etc you'd probably be ok. I'd mount the intake as high up as possible. I don't know how powerful the fan is, might have to upgrade to a higher cfm unit if the hose run gets long.

That is probably fine as long as you use the correct cartridge.

Also wear a Tyvek suit nd cover as much of your skin as possible.. isocyanates can penetrate your skin..

Thanks Greg, thanks Tim.

Second the reco for cheap tyvek suits. Disposable, local auto paint supplier has them.

Will do, thanks.
