DPF 8000 Wall Wrap

[mikeinpdx]

We're having some issues with an Arlon wall wrap adhering to a concrete block wall. The wall was cleaned and paint was in good shape. Material adhered well to it.

The issue is that now it's sunny the wrap is shrinking quite a bit. It is about 9' tall, has been up for about two months, but in the last week in the sun, it apparently has shrunk by several inches.

I'm hoping that after a week in the sun, it's finished with the rest of the shrinkage. Before, we had heated and applied with a Roly Pro ( time consuming ). I realize 3M has the TSA-4, which I might make an emergency buy on, but I wondered if anyone has tried a faster approach. The installer is confident about using a weed burner and has done it in the past. I wondered if using that to heat an area quickly, then using a silicone rolling pin might be a quick way to reheat and press down. Probably looks stupid, but it seems like it's doing close to the same thing and might be faster.

We are having the exact same problem. Installed in August on long flat, unpainted concrete wall. Surface prepped by power washing and letting dry for 4 days, heated and rolled during application, even put edge sealer along the top edge. We noticed a lot of contraction after a few weeks but did not feel we needed to address at the time. Now it seems that large areas (particularly in the corners) have lost all adhesion...we can easily just pull it off with zero effort. We're trying to get some recommendations from Arlon on how to proceed but not getting a lot support from the distributor in helping us get in touch with them. I'd be interested to hear if you found re-heating to work (though it might be too late for our job) and if you had any conversations with Arlon regarding the issue.

We may reprint just the sections that are failing with DPF 8000 again but if it looks like more sections are failing then we'll have to redo the whole job but probably with a different material. We opted to go with DPF 8000 over 3M 8524 (b/c I believe at the time it had 2 yr warranty on masonry but now it looks like it's been downgraded to 6mos). Anyone with other recommendations on materials that would last at least 2-3yrs?

Arlon is pretty upfront about the shrinkage of this product. In fact, it is one of the first things they talk about in the marketing video I saw for it.
It happens because of the softness of the adhesive is what they said. No real solution other than trying a different material.

I am about to install some on an indoor wall, and I have the same reservations, but I went with this, because the paint this company has on the wall has historically not done well with other less tacky vinyls.

Good luck

DPF 8000 Is a great product. It wont last long on rough surfaces. 3m makes a decent wall graphic film, dont remember the number off the top of my head.. but also you can use the 3m envision apparently.
