Advice on sandblasted mdo sign

[Stormyj]

Hi all,
Im mounting a sandblasted sign mdo, 48"x96"x1.5" on the side of a building with vinyl siding with plywood underneath. The previous sign, 36"x96" was mounted with straight screws through the sign and into the side of building. Seems a bit unprofessional. How would you guys mount this sign. Any help would be greatly appreciated. Thanks.

You sandblasted MDO? Screws into the subsurface ply is the way I'd do it, too, for what it's worth.

I hope you meant HDU. Since sandblasted signs are usually at least 2.5" thick you can use brackets into the edge, studs on the back or a cleat

Hdu. Duh

As was already mentioned, studs or brackets. If it's in full sun, I'd put a rigid backer (.063" aluminum) behind it, too.

Take the easy way out. Screws straight through the face of the sign, incorporate them in strategic parts and put a plug in it as a decorative rosette kinda deal. You can even charge more for that deal.
