Best Adhesive for External Sign??

[prof]

I have a relatively small sheet metal sign that I need to affix
to the outside of our brick building and I can't use screws.
What is the best all weather adhesive to use to secure the sign
to the building??

TIA,
prof

Tons of tube-based adhesives (think caulking gun) at local hardware store. Liquid Nails is one type of product. Ask the salesperson.

That's quite amusing because I just happen to have some liquid nails
handy and I was planning on trying it if I didn't get any better suggestions.

Thanks,

3M 5200 Works and cures underwater.

If you're just gluing an ultra smooth sheet of aluminum or sheet metal to a brick face any knucklehead will be able to peel the thing off in a few minutes with minimal prying.

I know you said you "can't" use screws - but I would use Tap-con screws.
Just a thought...and I own a sign shop.

Glue velcro®to the brick and the back of the sign and let it do its thing?

I used 3M windshield adhesive (just as nasty as 5200 to try to remove) to stick a sign to a painted concrete foundation and found the bind's weak point was the concrete paint 's adhesion.

One windy night my sign blew away.
Left me with 6 spots of no paint to indicate where the sign had been.
