Paint Question
Posted by Martin Pearson on February 25, 2003 at 10:45 pmCan anyone advise on how long a van should be left after a respray before graphics are applied so the paint can harden ?
I have a customer who has bought a second hand van which is blue. He has arranged to have it sprayed white and wants us to graphic it as soon as it is painted so he can put it straight to work.
So the question is, is there a recommended length of time you should wait before applying graphics?signscript replied 22 years, 2 months ago 8 Members · 8 Replies -

Depends on what paint they have used abit, I have fitted a van up the next day after spraying (with 2 pack) and the spray chappie was more than confident I wouldn’t damage/pull his paint off….(and that was sprayed on a winters day with no baking oven)

Hi martin
There are a lot of techy replies can be had at this question. I’de advise 2 days minimum after its out the oven, if he can wait. That’s if there is an oven! Don’t be caught out by that…
Paints give off gases/vapours whatever they are called, for a couple of days after being painted and if you apply a graphic perfect to it then you may go back a few days later to find millions of tiny bubbles/pimples.
What do you do now? Strip it… ok! But remember you applied it to soft paint… strip the vinyl and there is a good chance the paint will come too…I was caught out a while back by this. the paint shop was late on spraying so insisted we applied when it was out oven. So I did. Spot on job. Very simple actually… 2 days or so later cutomer wants it done again. I said why he said bubbles….. you know the rest! 🙄 🙄

The recomended is 6 weeks martin but I have done them 4 days after if they have been oven baked.
Watch out for really bad preperation work on paint jobs hard to detect until you have to remove anything and the paint comes off down to the primer cause they never keyed it properly before they put the primer on.
I try not to over any sort of Guarantee if the customer is pushing you to put graphics on a vehicle that has just been painted and they wont wait.

2 pack paint relies on a chemical reaction for the paint to cure so will harden much quicker. The older type of paint system (cellulose) relies on evaporation for the paint to dry.
Nowadays, most bodyshops use 2 pack as it is far superior but it requires breathing apparatus to be used safely.
Ask your customer the type of paint used – if 2 pack you only need a couple of days to know it’s ok – but if cellulose I would say give it at least a week before applying vinyl.
Put the onus on the customer to advise the type of paint used. If in any doubt assume it’s cellulose and allow at least a week (or even longer if it’s cold weather).

And if its reflective vinyl, go for two weeks minimum.
Like other here, I have been caught in the past and now make it perfectly clear to the customer that I will accept no responsibility if they go against my advice.

Thanks for the advice people, have spoken to the customer and the coachbuilder. It is a 2 pack paint and he has an oven, it is recommended to leave it 48 hours apparently. Sprayed today so we are leaving the graphics untill monday.

sorry missed this one, well ive had loads of experience with this one, my old workshop used to be next door to a vehicle refinishers, they had the contract for 4 taxi companies, target vans, tnt vans and initial city link vans, so there were lots of new panels and lots of new vinyl for me to slap on, if its 2 pack then you need 48 hours, bare minimum, a week would be good.. BUT this is only if it is a GOOD paint job, there are lots of paint cowboys out there and if its a naff job then even 3 weeks wont be good enough, and i would agree with john that if its reflective i would leave 2 weeks..
I have however put vinyl on a van 4 hours after it came out of the oven the damn thing was still warm, i used 5-7 year metamark vinyl, and i then had the pleasure of removing the vinyl when the company changed their logo three months later, i was expecting a nightmare .. but it came off fine, no problems although i wouldnt recomend it !!hope this helps
