Bonding polymetal to concrete?

[Marie]

Any suggestions for adhesive (or VHB tape) to use for mounting a 16"x68" polymetal (brushed gold) sign to an exterior smooth concrete face? Thanks!

Why not physical fasteners ??

VHB foam tape & lexel or poly construction adhesive

Is this concrete new or old? Painted or not painted? Smooth or rough? If older, painted and smooth, VHB and construction adhesive should be OK. I would do physical fasteners on concrete no matter what but if you can't I'd be sure that the concrete surface can deal with adhesive.

Keep in mind your human traffic and pedestrian safety. That might determine what you're comfortable with if the sign is elevated over a foot traffic area.

IIRC brushed gold will fade to silver in direct sunlight - I'm trying to remember how my brain thought this but I'm pretty sure it's a fact from sometime over the last 10 years.

We use Tesa 7065 tape from Grimco for mounting metal signs on concrete walls. We've used it enough to be quite confident with it – no failures yet. It's strong enough that we warn customers it may take some of the concrete with it when the sign is removed.

Correct. Polymetal brushed gold will fade to silver in the sun, and is therefore recommended by the manufacturer for indoor use only.

For hidden fasteners, I physically attach a backer to the concrete - then attach the sign panel to the backer using a combination of tape and adhesive...

Yes, don't ask me how I know this, I have to drive by my mistake every day...
