why is my matt vinyl not adhering properly?
Hello all!
I’ll try to keep this simple but will probably fail.
I was asked to do a job by a customer who’s previous sign man refused to do because he ‘had problems with matt vinyl’. I telephoned my supplier who told me that was rot and matt vinyl performed as well as gloss. I have applied matt vinyl to the side of a spray painted fuel tank which is a teeny bit stippled. I used soapy water and the vinyl doesn’t appear to want to stick very well. I have peeled back the vinyl and the gluey surface is all white. It is only 6 hours old and in a coolish workshop. Should I expect the white gluey surface to dry very sticky or have I been ‘sold a pup’? I have applied another piece dry and this seems to stick a bit better. Have I made a mistake with the wet application?
The vinyls are black and white ‘Rimark Ritrama L&S Series’ and rather alarmingly red ‘Oracal Serie 620 Removable’!
Any opinions waould be greatly appreciated.
ps. The fuel tank is off to Ghana in a week and I’m not a very good flyer.

it is a water based adhesive mete, that is why it has gone white. Best reapply dry, or use a material with a solvent based adhesive.
nothing wong with matt tape at all, just as good as gloss

just to add, you should not apply ‘removable’ vinyl wet in truth. It is a ‘week’ adhesive in the first place, adding water will almost negate its effectiveness

Hi Gareth a couple of questions how long had it been sprayed before you put the vinyl on ?? not familiar with rimark. and why removeable ?? never had a problem with matt vinyl it performs the same as gloss but not shiney. and I really think your main problem is soapy water why not dry !!!!!!
I don’t mind flying if someone is paying 😀 😀 😀

Deleted because it was a load of balls. 🙁

Thanks all, um pardon John?
Lynn.
The job was 12" wide black stripes with a thin red pin line over the top and white text added, so I thought water for the potential bubble problem. The vinyl was sprayed and then immediately applied.

Gareth,
My comment was balls, not your question. I should have read it properly before I opened my gob. 🙁

Gareth when I said sprayed I meant the tank not the vinyl , and you still didn’t say why you used removable vinyl I don’t expect it will come back once a year for a re-furb !!!!!
(yes John is very pardonable nice pic John)Lynn

Lynn,
Ah! It has been a long day. The tank was sprayed ages ago. At least a few weeks. It seems extremely stable. I did not know I was using removable vinyl until I read the backing paper advertising. I’m an idiot!Shane,
Why is water based adhesive being used on vinyl which is going to be outside for most of it’s life? Or have I just answered that question?

Gareth, a few manufacturers use waterbased adhesives for their cheaper product lines. The waterbased adhesive will not fail out in the weather if it gets wet, but will be harder to apply in some circumstances if applied wet….. If that makes any sense.
Water based adhesives are generally used on the shorter life span products but solvent based adhesives are usually on longer term products. Essentially, solvent based adhesives can be produced to supply a greater range of adhesision situations, and waterbased adhesives are usually less aggressive.
Hope I have not confused you too much mate…

Shane & Lynn,
Thanks for all your input. It isn’t sounding too good this, is it? I’ve made a decision.
I’m going to rip it all off and use banner vinyl (applied dry) and hope I don’t get a call in 3 years asking me to nip over to Ghana to re-apply the stripes!

Gareth ….. it’s all already been said. 😀
I once applied a vinyl with a water based adhesive wet on reverse onto clear acrylic panels!!! So it was a white and terrible looking. BUT ….. it did dry clear and there were no problems whatsoever with it from then on.
As far as possible fit it dry. But leave it a little while and see if it dries out. If the vehicle can be sat somewhere fairly warm then that may do the trick …. outside if it’s not raining where you are ….. like it is here BIG time at the minute 😕 -
