I'm not painting my KR yet, but other projects such as a cub cadet resto, using single stage urethane / catalyst. Apparently you really dont want to breathe any of that stuff. In doing research I've learned a lot and only certain respirators will protect you and only for a short time. Also, once opened, the charcoal starts to "fill up" even when stored. Best to store in a sealed zip lock bag for that reason. I read one aircraft painter whos shop standard is to only use the 3m respirator cartridges for ten minutes before discarding! (they normally use supplied air). The bad stuff also is odorless (although the paint carries other odors with it).
So the bottom lines is that a SUPPLIED AIR RESPIRATOR is really the way to go. Hobby-Air is a popular one for occasional use, and comes with 40ft of hose for about $400 from Aircraft Spruce. There are 3 hood options, half face, full face, and over the head tyvek style. I am not sure if the pump unit has any filtration/hepa or charcoal. So anyway, the main question is whether anyone has made a DIY supplied air system? I mean, its just an air pump and hose into a mace mask, with the air pump outside of the painting area right? How about making a fitting for my 3m respirator that pushes this air thru the OV/P100 cartridge OR prefilter by making a pump unit that pulls thru one or two of those, thru a hose (cheap garden hose? other?) and into a regular respirator mask? Just throwing this out there first to warn new painters from the dangers, and would love to hear options others here have used for paint protection... As an aside, I bought a $22 harbor freight traditional paint gun (bottom canister) but found out that HVLP gets more paint on the work and less overspray and will grab one of those. I saw a test and the cheap HF guns made out pretty well the main advantage of the $600 ones is durability not paint quality. _______________________________________________ Search the KRnet Archives at https://www.mail-archive.com/krnet@list.krnet.org/.
