large HDU install questions

[mangsigns]

Hi there,

I have a few large 2" HDU pieces to install into stucco and the customer wants a 2" standoff. My first thought is to use 8" long studs with gem pads so I'd have about 5.5 inches of stud into the wall. Is there a more practical way to do this install?

You might want to consider adhering a rigid back on the HDU... Either MDO or polymetal, depending on the size of the signs.

rigid backer

the signs are various shapes roughly 2.5' x 3'...my thought is that if I use construction adhesive to glue the studs into the foam, about 8-12 studs would be fine. But the backer is now making more and more sense safety wise. Will the foam fail eventually?

You don't need to back up a wall mounted sign that size and thickness. If you want to use studs drill oversize holes in the hdu and use epoxy to hold the studs in.

Epoxy the studs into the back.
