What temp. is to hot for painting. It have been in the upper 90's around here and was wonder if I should wait for it to cool down a bit.

Re: temp
 

what type of finish are you spraying? the can be a big problem for some.

Re: temp
 

imron is what I sprayed this weekend. The paint never seemed to flow well.

Re: temp
 

well i know 100 is too hot to be working with bondo!!!! by the time i was done mixing the hardener it was starting to kick!!! i ended up putting the bondo and hardener inthe fridge for a while then mixing it together...gave me just enough time to put it on the golf cart i'm workign on :D

Re: temp
 

make sure you have the slowest reducer they make for it. thats about all ya can co for the heat :cool:

Re: temp
 

Like dave said use the slowest redecer you can get. I do know that the newer Imron doesn't flow out as well as the older stuff did, even in ideal conditions. The larger area you are painting the more problem you are going to have, if the reducer is not hot enough.

Re: temp
 

Looks like I have screwed up then. The paint store sold me the paint and activator. The can didn't say anything about a reducer. All is said was 3 parts paint and one part activator. I found a old can of Imorn which I used on the trailer and it mention using a reducer

Re: temp
 

Depending how old your old can of imron was, it is probably not the same. I think the new stuff does just call for the paint and activator. However if I was determined to use it I would add a little bit of a good grade reducer. (a high temp reducer)
have already painted it ? ,what are you painting? how big of area?

Re: temp
 

Painted the transom of the boat. I still have plenty of paint left over. Guess I will see how if looks after I color sand it and buff it. I have only used imrom a couple of times and the other two times it came out great. This has more orange peel than I would have liked.

Re: temp
 

I think the orange peel is probably due to the new style imron
vs. the older stuff. If you spray it again you might want to try
adding a little reducer.

Re: temp
 

interesting you mention that. over the last few years the manufacturers have backed of on the "recomended" amount of reducer to use to keep the "as sprayed" VOC's down. you still need it but they couldnt list it in the directions or else it would no longer be compliant. actually you didnt screw up you were just a bit misled by Dupont. :D

Re: temp
 

Thats right Dave. It seems that as the voc's go down often does the sprayability, and at times the quality with it. Thats why practicly all of our clearcoats are "high solids" now. And why the vast majority of painters are spraying with HVLP guns. You just have to be carefull about putting to much reducer in some of these paints that do not call for it. However I wouldn't be afraid to reduce that imron a little bit. You also have to watch some of these paints that do not require reducer, and see if they offer a couple differant types of activator. Sometimes they offer them in differant temps.
Later, Scott

Re: temp
 

Thanks for the info guys.

Re: temp
 

kinda feels like we have been left to figure it out for our selves on some products. some stuff just takes experiance to get ya through it :D luckily we can share that here and help out sometimes.


Scott, what are you spraying with now and what products? i spray mostly PPG's DBC bases with 2021 clear. gun i use is devilbus GTI and a Plus gun for clear although i dont use the Plus gun for the bigger boats because its rather ineficient (non-HVLP) but it does spray nice. most of my work is on larger boats, not to many cars for me anymore :drink:

Re: temp
 

Any time Dave. We are spraying the same stuff. 90% of what I spray is 2021 over DBC base. (good product) With the acasonal use of some House of Kolor. It helps to have all the mixing equpment in house for the PPG stuff. I mostly use my SATA Jet RP with a 1.4 It works really well for me and sprays a nice pattern. I also use a Binks M1G that I love, but it got to where It wasn't spraying as nice of a pattern as my SATA.
Here is a pic. of my Pantera it is listed in the classifieds.
Also another project I recently finished. 37 ford coupe 2004 streetrod Nats in Louisville kY ( Indoors in PPG's Booth )
Talk to you later, Scott

Re: temp
 

I will check tonight. The trailer came out perfect and nice shine and smooth. The boat has a slight orange peel to it. I noticed while searching for engine parts in the garage I still have the old cans of imron.

Re: temp
 

nice look'in pantera DC. i have seen that before on here. finally somthing different :D i like the palm trees. sounds like we spray the same stuff. i use the occasional House of Color stuff when i need a certain color but 2021 is my main clear. i have heard good things about the SATA gun but haven't got to try it yet. there is a SATA dealer/rep on the board that has offered one to me to demo but i haven't had the chance to take him up on it yet. i'll hafta look up his screen name and try it sometime. i am building a new race boat for myself right now and that may hafta be the test piece :D


hows it go'n Art :D i hope you are keeping everybody in line around here. i have been off line for a few days out on the boat :drink: :drink: :drink:

Re: temp
 

OK Dave, what's the scoop on this ???? Inquiring minds want to know!
You planning on racing? What series and class??

Re: temp
 

I just want to know if he's gonna need a crew - I would be the first volunteer.

So, Dave, what ya got up your sleeve??

Re: temp
 

hehe . . .its double top secret :D and yes . . it will be very cool. i will be posting pics soon :cool: :cool:

Bouy i will need all the help i can get. anytime you wanna help out an crew would be great. hopefully i will catch up with you in Key West this year

Re: temp
 

Just to let you guys know resprayed this weekend and the reducer made all the difference in the work. Thanks guys.

Re: temp
 

I am glad to hear that it helped!! Anytime.

Re: temp
 

I used a retarder for hot weather Imron applications. IMO, spray a hull side with Imron at 50-65psi thn clear with PPG 2021 clear x2 to slick it out( they have a DT895 that dries slloooowww(yes, it will run if you get happy fingers) If you decide to sand/buff, PPG will be sooo much easier and deeper than Imron.
