Protection using iso-cyanates.

[Bill Douglas]

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.

as I'm sure you are aware of the iso-cyanides get exorbitant thru your skin.
so you need full body protection no mater where your using the products with them. this is a quality paint suit head sock proper gloves and even eye protection. when it comes to a respirator an air supply system is best but if you can or do have a way to exhaust the overspray out of your spraying area you can use a none air supply or cartridge type one.
when I was a kid painting in my moms garage at home. I made a exhaust system for the garage.
I took 4 box fans and made a faults bottom panel that fit in the space of the garage door then closed the garage door into it with the fans blowing to the outside. in moms garage we had two windows so I took AC filters and made a frame to put the filters in to fit into the windows when opened for the fresh filtered air to come in.
it worked great I could spray a hole car with no overspray hanging in the garage and get some pretty clean paint jobs.
spraying out in moms driveway just never worked out good to much wind or bugs or dust or the worst was about 10 minutes after I finished one job a cat jumped on the car.

Oh Jeesus that's funny.

Thanks for the good advice.

Haha, when I was a teenager I woke up one day and decided to paint the Beetle. I had some proper car paint and ran a power cord down from the house, used an electric sprayer, taped newspaper over parts then painted.

The car looked brilliant. I think because I used a Din 4 viscosity cup and by luck the paint laiyd down beautifully. A leaf fluttered down from a tree and stuck to the car and I reached for it. A voice in my head said STOP, which saved the paintjob I feel.

Zero planning and prep', but it sure did look good LOL


Edit: mu uncle bought a brand new Ferrari and drove it out to se his friend on a farm. they came outside to admire the car and found his pet goats climbing around on it haha.

HAHAHAHA yup the 1st car I painted was a VW bug. I used rust-oleum primer I thinned out then bought some royal blue rust-oleum paint and white rust-oleum mixed them together to get a light blue thinned it and sprayed the car. sprayed it with a old at that time binks pressurized cup spray gun and a 4.5 HP 110 volt compressor. took 24 hours for the paint just to setup some and over 3 days to dry enough to put the door handles and things back on the car. I too used news paper to mask it.
for a 14 or 15 year old kid it didn't come out to badly. I put some used snow tires on it and drove it in the corn fields and dirt roads around our house. if I remember right my friend and I both came up with 50$ each to buy the car.
god we had fun with that car! one time we were way the hell out in the woods on a single track trail and these guys came along on dirt bikes wondering how we made it out in the woods that far in this trail.

Haha, great first car story.

You just reminded me. When I was school kid I bought an Austin A40 truck that need paint. Being a thirteen year old I first painted obscenities over it, then the next day painted it with blue rattle cans. It looked OK in the eyes of a school kid. But in the right light you could clearly read what was written underneath.

One evening, beautiful lighting, I sold the truck to an elderly gentleman. I sure had a good laugh seeing him driving around town with semi visible obscenities written over the cab.
