Squeegie marks on lam'd window perf application

Last week we did a large DRY installation of window perf using Contravision Performance 60/40 with DOL 1360Z OPTICALLY CLR overlam. It went on nicely but a week later we are still seeing squeegie marks from the application (we used a soft felt squeegie to apply). Has anyone else experienced this with this material and will it eventually settle in and the marks disappear? Thank you in advance for your feedback! I'm trying to reassure our customer that these marks are only temporary...

Usually after it's in the Sun for a day or two they go away. Does it have access to direct sunlight? If not it should still go away it just takes longer.

You could always use a heat gun and low and heat up a little area and see if it goes away if you're concerned, but 99 out of 100 times it will go away on its own

We experienced the same issue using 1360 on perf. Using a thicker optically clear laminate has given us better results and no squeegee marks. The marks happen because the laminate is contacting the glass in some areas. Sometimes it would clear up and sometimes not. The extra thickness of the lam also make install a little easier.
We have had good results with this product. https://www.fellers.com/fellers-sho...clear-uv-overlaminate-permanent-adhesive-4-yr

Curios. Why lam perf? If it is for a better margin, than it's cool. Printed and mounted perf since 08' Not one have ever lam'd. An accounting firm we did his windows in 08' was my second job. Started losing magenta after 3 years. I was annoyied that it lasted so long. : )

SIgn Up!

If rain gets into non laminated perf, you can't see outside of it. And some areas unlaminated prints wont last 3 years... Especially on store fronts where the owner pressure washes it. Around here, everyone laminates perf

Thanks very much for your comment and assurance, it does get a lot of sunshine in the afternoon, however, when I went by last week, it still had a lot of squeegie marks showing. Many of these glass panels are printed in a solid black, which may be part of the problem. Hoping when we go back out in a couple of days that it will look better. Fingers crossed!

We have always applied overlam to perf as it helps to make the areas easier to clean, and keeps the colors vibrant and true. We have some projects 12 years later that still look fabulous.

Interesting.

We used ND Graphic's recommended DOL 1360Z Optically Clear, Cast Gloss Overlaminate which is a is a 1.3mil, premium quality, ultra-thin, ultra-conformable optically clear cast vinyl film on a 2mil transparent synthetic liner. Perhaps we should have used a heavier lam on the face...

I think the thicker ones have less of a mark... But you should still be fine. We usually just throw on 8518, a thin conformable laminate that's pretty much optically clear.

When you're laminating all the vinyl / glue goes between the perf holes and sticks to the window.... So the squeegee marks are really just the vinyl sticking. Eventually heat / the sun brings the Overlam back to its original straight shape, which lifts it off from the perf holes and removes those squeegee marks.


I've never not seen squeegee marks go away, even on perf we put up in the window when there was no sun... Eventually it'll pull itself off.
