Any tips on how to stop bad bubbling on cast vinyl on vans?

[Brian Little]

sure its not dirt trapped under it

im struggling to understand how your having trouble with just black

[Jill Marie Welsh]

Are you applying in the sun?
Sometimes a hot surface can cause bubbles.
And black is a great absorber of heat.
I know it’s not what Rob would advise,
but get thyself some Rapid Tac application fluid and apply wet.
I get far less bubbles this way.

Sun, in England? where ?

[Jan Chambers]

I’ve been puzzled about it just being black as well as it’s the same make
of vinyl as the blue and the red. I wondered if the bubbles just showed up more on black but the red and the blue seem almost perfect. I know it’s not sun but I’ll try using the RapidTac and see if it makes a difference.
Thanks for the advice. Jan

HI There,

What surface is the vinyl going onto ?

Reason i ask is some surfaces notably GRP sided vehicles outgas over a very long period of time, Cast vinyl is very thin so slow outgasing will dissipate through the film , the black as Jill suggests aborbs the heat and reaches a higher temperature which speeds up the outgasing which in turn exaggerates the bubbles caused , if you strip away the bubbled area and the adhesive is stringy then its an outgasing problem.
Also type of paint could be the reason 2 pack paint is another that is dry to touch quite quickly but vinyl manufacturers will recommend upto 3 weeks before trying to apply vinyl for the same reason.

Hope this helps.

Thanks Cammy. It was a van that the vinyl was going on to and it was new. It was also stringy when coming off so I guess outgasing is the problem. I’ll watch out for this in future. Do you know of any way round the problem, apart from waiting three weeks before signing?

He’s a clever man that Cammy. Just taught me something too 😕

Thank God he’s clever – I’d never have figured the bubbling out and
it was driving me nuts. I even thought the vinyl was faulty at one point and tried a different batch.
