Hi-tac(?) vinyl with thick adhesive?

[Bengt Backhaus]

I know this is a long shot, but:
I just removed printed and laminated vinyl from concrete crash blocks.
The adhesion was the same on both concrete and reflective areas
and was pretty easy to remove. It feels more "rubber-y" than most vinyl.

Customer says its been on there for three years and was installed on site in 3-10 degrees celsius (37-50 fahrenheit)
And now they want me to redo it in the same material, but they dont know who did the original work.

The thing that might help someone recognize it is the adhesive.
It's thicker than anything i think i have seen. And it partially lets go from both the vinyl
and the concrete like that tacky stuff for posters.

my favorite hitack is arlon dpf8000
stuff is bonkers sticky, but I upgrade to 3M 8624 if I need to contour-wrap mortar lines/etc.

I use polar tack

My understanding is that Arlon DPF8000 has dbl adhesive and yes it does seem thicker that other hi tacs I have used.

We have used General Formulations 285 Roughmark for applications like this.

Thanks everobody.
I have ordered samples of all your suggestions.

It's been some years since i used Arlon 8000, and my supplier suggested Arlon 8200.
I'll ask for samples of both.

3M 8624 seems hard to come by here in Sweden.

That Arlon DPF 8000 leaves a lot of adhesive behind on our rollers and platen. Every time it is used the printer has to be cleaned thoroughly.

its just at the edges of the material, but a good point
...just use a piece of masking tape and dab at the rollers where this occurs after every roll/run. plucks up those goobers like a charm.

Really? I just did some stuff during our blizzard with dpf8000, including an insanely uneven brick wall. Stuff sounded like a trashbag until I got the heatgun roller out. I don't know how cold it was, no indication other than the numb fingers and icicles hanging from my handlebars.
Anyway, great stuff, I'm looking forward to going back in 6 months and seeing if it stayed. Does the 3m have a better warranty or does it just work better?

3M 8624 will stretch&contour, but the arlon8000 is really just for flat stuff as it's fairly rigid by comparison.
if its something permanent and the client wants their mortar lines contoured, then I upgrade to 8624, but if just spanning the mortar lines is acceptable then I'll use the 8000 but the mortarline-channels from the material floating & moisture/wind/etc. will deteriorate over time and start chipping/peeling away.

I started using dpf8000 when we needed a material to stick to HDPE, which it appears to be the only material I've ever seen capable of it.
still certain that it'll stay on the brick with some heat & squish, as you're basically just contouring the thiiiick adhesive layer, but wouldn't be surprised if a lot of the material is just floating between the peaks of the brick texture and could have some longevity issues.
