Is it ok to spray in a garage that has a hot air oil furance in it with the paint mist in the air?
Thanks
Jerry

Yeh its o.k. if you like to repaint and repaint and repaint because of fisheye problems..........NO its not o.k.,oil contaminates the surface and the paint will not bond.If you have already sanded the surface and you have been running the furnace your in for a nightmare.
Go to your favorite paint store and get some gease and wax remover and pray for the best.Ask for the p-sheet that will tell you the correct way to use the product..........and find a buddy w/GAS heat

Jerry, I painted my velle last march in my garage....Oil furnace and a salamander heater, and there was no problem at all with fisheyes...matter of fact it came out fantastic...If you have oil contaminates floating in the air, you have a problem with your furnace..only thing about a garage paint job is more dust in the finish, but if you're gonna color sand and buff anyway, whats the difference...You can do it, just clean the surface well and dont have the discharge from the furnace blowing right over the car so it doesnt carry anything into the paint. As far as the explosive hazzard, I didnt run the furnace when I was actually spraying, I waited till the fumes cleared out for a few minutes before I started it up again...I had two box fans in the garage windowns.

Hot air, oil fired

Thanks to all you guys for the help

If that furnace has a flame or some sort of spark igniter, you're crazy if you paint in there. Mixture gets correct, garage goes "Boom."
The son of a friend was cleaning his motorcycle in his garage with gasoline.
The burner of the water heater kicked on, the air/fuel ratio was just right and blew the kid right out of the garage, set the garage and fire and ended up setting the house on fire as well. Ironic thing is, my friend was a LB fireman. When his kids called the fire departmment (pre 911 days) they were excited and transposed the numbers of their address. The fire department went to the wrong house which slowed their response time and additional damage occured.

Thanks Guys
I appreciate the help
Jerry

If anyone was wondering... the Upper Explosive Limit of gasoline is approx 7% and the Lower Explosive Limit is approx 2%. SO there doesnt need to be much fuel in the air when it reaches an ignition source for the BOOM to happen.

A residential garage is NOT a SAFE place to refinish a car. I know it is done often. It is not healthy. It is not safe.
Just because no one gets killed that often doesn't make it safe.
Ventilation requirements are MASSIVE.
All electrical motors, wiring, and heat sources must be explosion proof or in a remote location.
Closing the garage door 3/4 of the way and putting a house fan in the back window, or door, does not qualify as adequate ventilation. &lt;CHOKE-GASP&gt;
If garage is attached to house, house may not have positive pressure. &lt;FUMES IN HOUSE&gt; If your air compressor motor is mounted low it will be in a vapor laden area. It is probably NOT ignition protected. &lt;BOOM&gt; Depending on when you garage was wired, the electrical outlets could be too close to the floor.
&lt;BOOM&gt;
As I stated before this is not the optimum environment to refinish a car. The dangers are many. Be careful.

Jerry,
it is against local regulations in most citys. Even turning on an elactric switch can trigger an explosion.
You will need a few fans to move any vapor out, if you are still willing to risk yourself and the house.

Good thing I ask.
i'm not very lucky making the odds worst
Thanks

I've painted cars in my garage and had no problems.Just work saftly and use your brain.It's probaly illegal to paint in your garage,but if no one calls whos to know.I've also painted in my driveway(waited till people went off to work so the fumes wouldn't kill them,and no one would call the DEP.I did my vette in my driveway and it looks like glass.(I've been paintimng cars for 20 years)Just alot of water sanding and buffing.And to all the guys that say bring it to a shop and have them do it,because it's not safe or you shouldn't do it in a residential area,if you don't have $4000 for a paint job you're gonna do it in your garage.

I have sprayed in the garage also. I don't have the water heater in there though. I use enough exhaust fans to move the spray right out. Like 427stringray stated: how are ya going to get your car painted when the body shops want $4000 or so.

The overspray floating in the air will put a lot of added wear on your compressor as well. Best to have it and the furnace in a separate room. Much safer this way.

the first i did was 2 years ago in my garage. I opened the garage door half way, turned on the overhead light and got to spraying. No fans, no respirator, no nothing. I'll NEVER do that again. My nose hairs were soaked in paint. From now on im just gonna make a pemporary booth out of plastic with fans and all electricals will be in a different room.

No matter how much ventilation you have - you should be wearing a good quality respirator preferrably air supplied. A dust mask doesn't count. Most of today's paints contain many dangerous solvents and other chemicals that act as anything from nerve agents to carcinogens. I too have painted in my garage many times and I won't pay $4000 for a paint job but I also don't want to die young so i wear a good respirator with the correct cartridges and use some big fans.

I bet all the tree huggers/EPA would go crazy over this email..... hehhehe

My main concern here would be the "What if?" factor.

Like, what if your garage catches fire, your neighbors house gos up, and you're home owners insurance doesnt cover it as it was against the law for you to be painting in your garage? You're liable out of pocket correct? Your house and any damages incurred by neighbors. That could spell bankruptcy real quick. Atleast for me.

Couldnt you do all the prep work in the garage and just rent a booth for the final shoot? Or just have a shop lay down the paint?

Just curious.

I think that's what I am going to do. Work on all the small panels individualy and then go shoot the whole car in a booth.

I think it's safer, some people just like to be able to say "I did it all in this here garage"

Have to jump back in on this thread. Let's talk about health. The catalyzed finished also absorbs into your skin. The worse the ventilation, the more your body absorbs.
We used to let the filters plug up in the spray booth, on purpose, moves less air, less dirt. This is before charcoal filter masks, shoot suits, and supply air systems. Down draft booths didn't exist. When we sprayed you couldn't see the other side of the hood. Sometimes (in our wisdom) we even turned the fan off while spraying.
As previously described we were soaked with overspray, nose plugged, all exposed hair covered with overspray.
For the record, even then, painters seemed to be sick more often, and died sooner than most of the body guys.
Then they started pruducing catalyzed enamels, then acrylic enamels, finally urethanes.
Painters really started getting sick then. I have buried most of them. The safety stuff and the information we should have had came too late.
Everyone has a different threshold of sensitivity to the products of today. It is kind of like saying "smoking is not bad for you, my uncle smoked for ## years and died at 95"
We have already lost many who could still be in this industry, because they are sensitized to the products.
I understand it is difficult to find a shop willing to paint our cars, it is still worth trying. There is no easy or quick answer to this problem. Be careful.
Note on liability. Not an attorney. In our area, when we store boats for the winter we shrink wrap them. It is very expensive. It is a big plastic baggie that is stretched over and edges are melted with open flame to tighten and hold to lower portion of boat. A thrifty boat owner decided to shrink wrap his own boat, in spite of Marina rules against. (I'll sneak in there on Sunday and do it) All done, smelled smoke, cut hole in shrink wrap to see what was wrong. POOF-FLAMAGE, took out his boat and over 20 others. These boats were in the price range of 50 to 200 thousand dollars. He is in deep Doo Doo, can you spell bankruptcy, and more. This too is an extreme, however, Be Careful-- Karl

If you are spraying solid colors it may be wiser to do a few panels at a time if you have to do it in the garage. Less dirt and dust in paint and easier to ventilate if your only spraying for a short while.
Also if you compressor is borderline you won't run out of air as apposed to shooting the whole car. Sometimes color match is an issue but I have done it successfully a few times myself, maybe just luck but its worked for me. On the other hand its nice to just get it done in 1 shot and be done also.
And as Karl stated this paint is nothing to mess around with! Supplied air respirators
or at the very MIN a full face respirator with organic vapor cartridges and hepa filter or other mist type pre-filters and change out the cartridges every hr or so. I changed mine out 3 times on the last car I painted!(of course I would never paint a car in my garage http://www.chevelles.com/forum/smile.gif Its cheap insurance for your lungs.

I really don't think anyone painting His car in his garage is going to get sick and die.I really think the people that died are the ones that did it everyday and didn't prepare themselves correctly.If you wear a long sleeve(or even get a tyvex suit) shirt,gloves and a good respirator I don't think you should worry.And also the fire and explosion situation,I don't think many paint shops or collision shops have explosion proof fixtures and switches.The ones I have been to seem to have the same ones that we have in our garages.The explosion proof ones are very expensive.I don't think many shops want to spring for that kind of money.When doing it just think before you do it and use the best safety equiptment you can get.
