I am planning on spraying the final coat of primer / sealer on my car tommorrow. However, looking at the weather forecast, it shows and 80 % chance of rain.

Is it okay to spray primer in such weather? In a garage of course, and compressor has a water seperater / filter.

Primer is PPG Epoxy

JeffW

water is fine just have to watch your outdoor tempatures.

its ok to spray with such high humidity?

and what kind of temps should you watch out for? (too hot, too cold??? ballpark figures and how paint will act in those figures please)

im looking into painting my own car soon in a garage setup also, just curious.

No spraying paint when its humid / damp / raining is not good, period. Dont know where you got the idea that it was Jeff

I'm no expert but that seems rather obvious. Even if it doesn't hurt the adhesion process, it will take longer to cure which means more prone to accidental bumps and other debris.

I guess its not that obvious after all

Sorry guys, you're way off base on this one... Jeff's right, no probs in humidity.. temp range is the BIGGEST factor...
How in th hell do you think they spray in Florida??
Here in the summer dog days of michigan, you get the highest humidity of most states... We spray every day.
Now, can more problems occur? Yep, you bet. But I'll tell ya one thing, for the backyard guy, a rainy day is probably better than most... It knocks the dust down... less bugs are apt to be flyin' around...
Select the correct hardener and reducer for the temp range and spray away...

JeffW

hahaha ya what kevin said........ where you get your info? gotta love how people think they know what they are talking about and can;t just say they don't agree.. or found this info ect...

where i get my info alot of education and reading and asking and doing my paint jobs..... where you get your info may i ask... (never mind just seen my car is older than you that explains it)


anyway the tempatures depends on what paint your using. the reducers have diffrent tempature rating slow med and fast set for cold weather. just be sure to have the right tempture reducers or catalyst. depeding on system. Read you t sheets and the ranges will be in there.

good luck with your project, keep you air dry and you have it made. use a water seperator close to where your spraying and not at the compressor. water cool then condenses so you will see the water further down the line not at the compressor. and if your air runs warm coil you air line in a cooler of ice then the water seperator, great little trick fro dry air.

Well guys, I decided to wait, as it begain to rain so bad last night, that I did not want to risk it. I instead spent more time wet sanding, then wiping the car down real good with oil and grease remover. As soon as I get off work today, I am going home and spraying the last coat of primer.

Thanks anyway for the info.

JeffW

you can search the project for all the info.. but ill make it easy on ya...its colbalt candy blue over strato blue all house of kolor products the gfx are platnum pearl.

thanks

No your wrong, humidity and water are just as important as temperature. I might be young, but for being as "experienced" as you claim to be, you sure are talking . An ideal paint temp range is 60 - 80 F. You dont want to paint while its raining, or to be safe, a day or two after its rained. Water can ruin your paint job.

We bake everything at the shop I work at. Primers, Sealers...everything. Temps are probably one of the biggest factors when painting....anyhow, what Jeff and Kevin said are totally right

You guys cannot be serious when saying that water doesnt matter when it comes to painting.

TEMPERATURE, HUMIDITY, AND WEATHER ARE ALL EQUALLY BIG FACTORS

cooltc2004

This is totaly correct

Make up your mind.

/edit: And im not trying to be a hardass / ******** / know it all / rude person. Its just your information is clashing from, what was, general rules in painting.

So johnny blaze, you paint cars. I would like to get mine painted. Maybe we can talk sometime.

KEVIN G.

I'm sorry, colt were you spraying outside??

And for all my , call me when you need your car painted.I'll remember to tell my customers that, when I can't paint their car, cause it's 90 degrees and 80% humidity outside...
I'll make sure to remember to send them to your expertise and years of experienced, post.

In a painting booth its totaly different, because the climate is controlled. But im sorry, if you think that rain and humidity doesnt effect the paint job, then you dont know what your talking about.

Many times have I seen people being told that they cannot get their car painted because of the weather, and these are high dollar, professional paint jobs. There is nothing more to argue, for all your experience, you sure dont have much to show for it. Oh, and I dont claim to be an expert, its just common knowledge.

KEVIN G.

Let me take you to school, son.
Very few boothes are CLIMATE controlled! (by this I mean humidity...) They are air controlled. Paint is dried by the ammount of air FORCED accross the panel that is being refinished. The process is accellerated by HEAT. We bake the panel to aid in many things...we can buff the panel sooner, assembly can be achieved at a faster rate. the vehicle can be delivered sooner. The only thing that can CURE a paintjob is the passage of time.
X-ammount of days need to be achieved to release the solvents trapped in the paint, before it is cured.
NoW, EXACTLY WHEN DID ANY OF US SAY THAT HUMIDITY DID NOT AFFECT A PAINT JOB??!!!
NO ONE HERE HAS SAID ANYTHING OF THE SORT!!!
YOU are claiming that a vehicle cannot be painted when it is raining, I'm sorry to inform you that approximately the whole month of April in Michigan, (most years) is here to prove you wrong!!!
I RUN close to a million dollar a year body shop, A PROFESSIONAL BODY SHOP...A GM DEALERSHIP BODYSHOP...
I think my boss would get a little irate if I informed him we couldn't paint any cars in the spring 'cause of the rains...!!!
I don't CLAIM to be an expert either...
But my certifications do...

U guys ever see that show on TLC i think. When they showed how the vettes get made and painted.. That was a controlled env. Well they have water running down the walls to help in overspray. I think its ok i have never saw anything on a paint can saying do not spray on high humidity/ rainy days. Only about outside temps. I might be wrong. I'm not a painter. But have worked in bodyshops for sometime now. And I have had painters tell me to paint on days that its raining.

cooltc2004

Yes, unfortunatly I dont work in a "million dollar GM paint company" so I have to spray outside.

Maybe where you live where its "90% humidity all the time" you have special paint, but we dont have that kind of paint here.

I dont know of to many high dollar painting booths that dont have climate control. Surely if your company is a multi million dollar company, you could afford one.

funny, usually when it rains, it gets humid.

Nope, not once did you mention humidity


This arguement is stupid and pointless. You can continue and argue with yourself if you wish, but I know who I would never have paint one of my cars.

KEVIN G.

Read my post.. Nowhere did it say humidity would not AFFECT a paint job...IN fact
(uh...from my very first post in this thread.)
Humidity CAN AND DOES affect a paintjob, But it sure the hell ain't gonna stop me from spraying... Because I know how to paint a car, and so do each and every one of my employees.
You are trying to say that You cannot SPRAY when it is raining?? You're wrong.
No "special paint".
I just told you very few do...
I spent sixty grand on my booth. Spraybake 1000... top o' the line about seven years ago.
That's a shame, cause you're missing out an a very fine job indeed.
Keep spraying the way you wish, but the offer still stands, get a bus ticket to MI sometime and I'll show you how to paint a car.

Im going to respond, because I think there is a misunderstanding. Now by "you cant spray when its raining" was for circumstances like mine, where you paint outside. When you disagreed with me, I didnt realize until you told me that you have a painting booth, and that obviously kills that circumstance. Now not having a humidity control, lead me to as about the special paint. By speical paint I ment additives for the high humidity. Here in Ohio it doesnt get that humid all the time, very rare in fact. Humidity, depending on the paint, can effect it very well, even to the point where it turned red into white, untill is was buffed. I missed where you said that "can it effect a paintjob? yes". I appoligize for that.

Painting booths, at least the ones I've seen in catalogs and on the specialty shows, all had climate control, the high dollar ones that is. Now 7 years is a long time, and the technology is probably more advanced, but I still have not seen many paint booths without a humidity control. That doesnt mean they don't exist, but I wouldn't classify it as "most dont", thats all.

Im one that can admit his misunderstanding and being wrong, like I have above, but here where we paint, rain and humidity prevent us from painting. All over the state I have seen companies tell customers that their car cannot be painted today because of the humidity / weather. This included high dollar paint companies and even maaco. I bring up maaco for the only reason that they are out to make a quick buck, and I would except them to spray no matter what.

Now being my age I AM still learning, and I'll tell you what, I might have to take you up on that offer of yours

I hope that any bad blood between us has been put to rest, and possibly we can learn to get along.
