Dumb questions BUT??

MSS3020 · Apr 24, 2013

I use a compressor and paint gun to prime and paint with. So a year ago I painted my sons front fender on his mustang and the next day was stuffed and had a sinus infection... Last week I painted a tailgate for my truck and next day stuffed and sinus infection. I know your suppose to wear resp. gear which I have since bought AND will use but is this coincidence or anyone else sensitive to this stuff.

Yes some people are more sensitive then others.

On the can with isocyanates it states air supplied mask... to be totally safe.

A couple links on the subject

I learned back in 1978 when hardner (isocyanate) first came out for Dupont Centari. It had no affect until 4 hrs later after supper. My airways would swell shut and couldn't get enough air to blow my nose. Like an athesma attack. Then about an hour after that it all let loose and would cough my head off for an hour and then would settle down. I was so sensitized to it that I had to discard paint suit and change my cloths before I removed my respirator. Supplied air??? Only chemical plants used them back then. I don't know if they even made lightweight portable ones yet. The full face respirator did the job for me. Long as I used that it didn't bother. They say they don't filter it out but the real reason they don't recommend them is because of faulty fitment issues.

If you use hardener you need supplied air. If you did not use hardener all you have to have is a charcoal filtered mask. If you are truly allergic to the stuff you need supplied air for everything. If you get sinus infections when not painting the fumes may cause it to happen more often, and you probably should not be around paint at all. Qualification is I'm no doctor, you need to ask one. The fumes do affect me, I avoid that by using explosion proof exhaust fans in my building along with supplied air for hardeners. If you paint outside you will still get the fumes.

you could be getting stuffed up from painting but it takes a week and a half to get from stuffy to sinusitis. I used to get it three-four times a year before I started irrigating them. Now if I feel sinus pressure I go irrigate and in ten minutes it is gone.

What a painter friend explained to me what's important is the air movement in your shop or paint booth. He says the paint booth at work he uses is removing the mist at a high rate constantly. In a your do it yourself shop with just say a 16" fan in the wall venting the fumes you maybe alright for a little job like a door or something. But a bigger job like a big piece of equipment or whole vehicle the spray area over loads and a charcoal mask can't filter it out well enough when the spray mist is so dense in the air. The air supplied systems are not that much more $$ then high end full face charcoal mask set up now a days.

Let me start by saying I'm plagued with chronic sinus infections myself and many things you breathe can aggravate and bring on a sinus infection. I'm a cabinetmaker and I can no longer cut or sand wood anymore without wearing a respirator. Then paint is so much worse than wood dust. You need to get a respirator. If you are using a paint with a isocyanite hardener, you need to get a air supplied respirator. Even spraying one vehicle you can put yourself in a major hurt without one. The stuff will go straight through a regular paint spray respirator.

Chase -- I misinterpreted your last statement. I interpreted your comment on supplied air vs charcoal filters as supplied air not being much better than a full face charcoal filter. As Showcrop said, you must have meant supplied air did not cost that much more than full face masks -- I haven't priced any of full face masks lately. My exhaust fans are pretty good at controlling the mist, but not nearly good enough to allow charcoal filters to be used. If you have already read my initial response, I apologise.

(quoted from post at 17:43:43 04/25/13) "The air supplied systems are not that much more than high end full face charcoal mask set up now a days."

That statement is not true. The intake is set outside in fresh air, completely away from the fumes. Remember that supplied air is positive pressure, the air is forced into the hood and comes out at the bottom of the hood, no mist can get in, I am breathing fresh air. I have two exhaust fans. You are partially correct about the air movement, but the fans are far better than no circulation at all. The mist is fairly constant, I don't paint enough to fill the area with mist. The fans I have are not bought at a hardware store, they are explosion proof fans made for the purpose. I cannot afford a downdraft paint booth. Professional body shops can use charcoal masks provided they can measure the the content of isocyanates and have a regular schedule of of changing the filters, an amature cannot do that. If I am not using isocyanates, in my case epoxy primer and the base coat of the base/clear system, I use a charcoal mask. The fans are a tremendous help. Your painter friend is mostly correct about the air movement, which I have under control, beyond that he doesn't know what I do and how I do it. There is NO "high end" full face or otherwise charcoal mask that is labeled for isocyanates for amatures, only for paint booths that can be monitered.

CNKS, I read it that Chas_99 was agreeing that supplied air is much better and not much more money than high end charcoal.

Showcrop, upon reading it again you are probably right, so I deleted it and reworded it. Thanks.

Chase_99 · Apr 26, 2013

No problem. You got it right. Those Hobbyair systems are pretty reasonable now like $400 which is not a lot for piece of mind.

Out of the blue last Nov. I had some wierd health issue's that I dealt with with all winter (feel good now) that was some odd ball rare thing with my ammune system and lungs and what not. All the blasted tests and trips to the doc trying to figure out what the heck is wrong makes a guy be more careful. They don't think it was something like paint fumes or nasty molds etc. but one always thinks it has to be something... as I've never had wierd issues like that in my life.

How do you guys edit your posts? I can't find the edit option.

CNKS · Apr 26, 2013

I have a Hobby Air, the first time I used it about 11 years ago, I set it in the window. The wind was from the wrong direction, the fumes headed for the window so I got a direct shot. I got over it, and now it always sits outside. This was before I had the exhaust fans. As to editing, if you are using the classic version you can't edit in that version. But, there is what is called the "modern view" at the top of the page, you can switch to it and use the edit function (most of the time). Sometimes it isn't there. You can use the classic view that I prefer or the modern view, which I use only to correct my mistakes.
