John Greenslade Posted December 20, 2001 Share Posted December 20, 2001 Plan on spraying primer over clean metal today. I got a high quality polyurethane primer (needs catalyst) yesterday and purchased a respirator that the body shop supply store said is what they normally sell. It is a charcoal and gauze filter type. I notice in some of the shops that they are using full air mask to spray. Is thnis necessary or is the charcoal and gauze adequate. I will be doing in a reasonably well ventilated garage. All other paint work will be done professionally but need to get the bare metal covered now. Thanks. Still trying to decide on spray gun. Probably will go with siphon variety on basis of cost Quote Link to comment Share on other sites More sharing options...
Tim240z Posted December 20, 2001 Share Posted December 20, 2001 John, As for breathing protection, if the primer contains cyanide compounds, then the activated charcoal is not sufficient. However, since you will be venting the area well, probably not worth the expense of breathing apparatus. I would recommend that you reconsider the gravity feed spray gun. In my experience, they work better and most pros are going that route too. Tim Quote Link to comment Share on other sites More sharing options...
DavyZ Posted December 20, 2001 Share Posted December 20, 2001 Ditto on what John just said: isocyanate is very dangerous to the human body--please consider very good equipment if you are using paint with this chemical. Just keep thinking to yourself, "full body protection..." Davy Quote Link to comment Share on other sites More sharing options...
John Greenslade Posted December 21, 2001 Author Share Posted December 21, 2001 Gentlemen, thanks for the comments. I checked the paint labels and no cyanates disclosed so charcoal filter should work with necessary ventilation precautions. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted December 26, 2001 Share Posted December 26, 2001 JOHN G-PAINT RESPIRATOR WHEN SPRAY PAINTING THE NEW POLYURETHANE PAINTS, AFTER ACTIVATING THE PAINT, LET PAINT "BREATHE" FOR ABOUT 15-20 MINUTES. IF YOU DO THIS, ALOT OF THE TOXIC FUMES WILL ESCAPE. REMEMBER THESE PAINTS ARE HIGHLY TOXIC SO TAKE CARE WHEN PAINTING. ALOHA, SUNNY Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted December 30, 2001 Share Posted December 30, 2001 Epoxy is a primer that needs a catalyst and does not have any isos. All 2K primers contain isos except a VERY new ppg 2K which is iso free. Read carefully. The masks do not filter isos, no matter how new they are. You need a fresh air system.

Guest gprix1 Posted December 31, 2001 Share Posted December 31, 2001 I got VERY sick by using a less than adequate mask once. It is a very rotten feeling; took days to feel right again. If I ever do my own painting again, I will make sure I have the right one. Quote Link to comment Share on other sites More sharing options...
