  • Help please! Vinyl on the window, wrinkles next day

    Posted by George Neagu on 7 August 2015 at 10:23

    Hi guys,

    I have applied printed vinyl on a shop window twice in 2 weeks and all I get is wrinckles just next day. I can’t figure out why.

    1st application
    – Avery mpi 3601 printed on UV Arizona 460 (due to 1800mm width) and applied wet with application fluid from Signgeer. All nice and flat and next day I had wrinkles.
    – unlaminated

    2nd application
    – OraJet 3164M printed on UV Arizona 460 (due to 1800mm width) and applied wet with application fluid from Signgeer. All nice and flat and next day I had wrinkles.
    – unlaminated

    I have applied hundreds of vinyls wet and dry on the windows and never had troubles but I always used Metamark, mainly solvent printed.

    I would appreciate if you guys can provide an answer to this. I meet the customer again this afternoon and I don’t know what to say.

    Thank you!

    Could it be extreme heat causing this?

    Hi Phill,

    This vinyl has been installed in London yesterday before noon and last night I got the pictures with the disaster.

    I believe the sun hits the window afternoon but we all now the sun is not that strong in this country.

    Phew…

    I think 3164 is a water based adhesive, so applying wet might affect the adhesive, so it’s got less grab.

    Hmmm… I think you are right, it’s water-based. I’ve been told it can be wet applied so I assumed is solvent adhesive.
    But let me tell you something, I stayed around it about 2 hours to make sure it is dry and no trace of fluid is trapped underneath. It was really strong when I tried to peel it off.

    Now, you can see in the images that the vinyl expanded. It’s an excess of material of 5 to 10 mm per wrinkle. This is weird to me..

    How exactly did you clean the glass, George?

    Here’s my suggestion..
    I think the tunnelling may have occurred as a conseqence of heat. If you allow a small expansion border around the perimeter (i.e do not fit the vinyl edge to edge in the pane) the tunnnelling will be avoided in future

    After I removed the previous vinyl, the glass was very clean but I gave it an extra wipe with water and a drop of soap, mainly around the edges.

    Just got a reply from Oracal Germany saying indeed the vinyl has water-based adhesive, therefore no wet application is recommended at all.

    This is another issue, Behind the glass there is a "light-box". really stupid idea and design but it is what it is. However, I cannot leave any border around the edges as the light will show and they don’t like it.

    First of all, I should say I am so glad as an Iranian sign maker to see lots of sign makers and sign painters and sign writers here in UKsignboards…
    Then bud! I am applying lots of vinyl on trailers everyday and I am still learning new things after 20 years being in this career.
    I am sure it depends on heat.
    It is so important when you want to apply vinyl how is the weather… shiny? hot? colt? raining? windy? etc
    I recommend you to clean up the surface and apply the vinyl at 8 A.M and not to use any heater to remove the water. Then you should regularly pull something like your credit card on the vinyl, horizontally and vertically with a few pressure to put all the water behind the vinyl out.
    The most important part is when you are puling the water out… You must be so patient and do your job completely.
    Be sure it works… And do remember! Not to use any heater during this job.
    Sorry if my English is not that good… As I said, I am Persian and I speak Farsi and I can’t speak English better than this! 🙂
    Thanks for your time
