Metal to Concrete adhesive recommendation?

[wavinwayne]

I have an aluminum sign that I need to attach (glue) to concrete block, and I don't want to drill holes in the concrete. Google AI says Loctite Epoxy Metal/Concrete is what I want. What say you all?

Liquid Nails makes a quality adhesive that will work for you. Can be found at Home Cheapo in the paint section! Might be ugly if you need to remove this sign at a later time.

This polyurethane based construction adhesive will be a permanent bond for that sign. Holds up well in the outdoor environment.

You may need to rough up the aluminum. And removal may damage the sign or block.

Won't have to remove. It's just a friendly "Get off my lawn" sign.

Ive also used red high temp rtv as a glue before. Sticks to everything.

I agree with Google AI, and yes, make the bottom of the aluminum as rough as possible. The "glue" should have a thick consistancy, almost like putty.
JB Weld might work too.
