Why is flooded window coming off.

Hi everyone.
We flooded the rear windows of a vw van the other week, we then lettered it.

It was really cold and we did it outside, the owner has now called in to say its coming off. Is it all down to the cold, we used Hexis digital wrapping vinyl.

You'll need to check the technical data sheet for the vinyl you've used but I would say you're absolutely right, from now until march I doubt we'll get more than a few days where you can confidently apply vinyl outdoors!

Glass is even worse as it tends to stay slightly colder than painted panels.

We do on average around 5 vehicles a week, when the temperature drops we tend to allow 30 minutes extra on a job so we can heat every vehicle with a gas space heater before fitting and try to leave the vehicle inside as long as possible to give the adhesive the best start in the curing process.

Hope that helps

I fit Oracal 551/751 to vehicles out in all weathers including snow on the ground
and never had a problem. Last year covered rear windows on several vans with Oracal 3164 in minus temps outside still all good.

I am unclear on your terminology, Denise. When you say Flooded, do you mean wet-applied?

If you have a look at the oracal application guide you'll find all the specific info you need for applying vinyl at minimum temperature.

It even mentions avoiding shocking the vinyl when taking from a heated workshop to cold temps outdoors.

You can get away with it if you heat the vinyl with a heat gun after application to start the curing process but again it's all in the application / technical instructions :)

i agree there are tech guides for the application i'm only stating what we get away with, a fleet of vehicles are not going to wait until we have warm weather. Even the workshops on site where open. I personally have never had a problem with vinyl failing. We use felt squeegees and these can generate heat when you apply the vinyl we normally rub over the app tape several times.

We mainly use Oracle 651 For vans and have always applied outdoors for 15 years never had a problem. Always apply with a heat gun and blast it on.
the trick is make sure its clean.

I use Iospropynol or an alcohol based glass cleaner first, to clean as much grease and dirt off as possible. I guess when you think something is clean, there is usually a product which proves it isn't. About every 6 months I use a clay bar on my cars paintwork after it has been washed twice with a decent car shampoo. Invariably the clay lifts off dirt that you would not expect to be there as the car looks and feels clean!

Also, depending on the vehicle, it may have a nano coating on the glass! I believe there is a product available which eliminates this problem, how though I am not sure!

Hi There,

Oracal do 3161DT and 3551DT , the DT stands for Deep temperature , can be applied at minus 5 , should help in the cold months ahead.

3161 is a monomeric 4 yr , 3551 is a 7yr soft polymeric.

Hope that helps.

Cameron
