Mounting large SignFoam sign to exterior wall...any suggestions?
Hi All,
I am making a one sided oval shaped sign that is approx 8 ft wide by 4 ft high. It will be mounted to the side of a building, and lit from 2 lights below the sign. The building owner wants to help with the installation because he doesn't want unnecessary holes in his newly re-sided building. I was planning on having the owner install 2 pressure treated 2x4s, horizontally, one about 3 feet higher than the other one. From these 2x4s, I was going to hang my sign. How? I'm not sure yet. :)
At first I was going to do something like a French cleat. I have no experience with that so I'm up for suggestions.
My concerns are:
- Should I have something like MDO behind the sign? The signfoam is 1.5 inches thick. I am concerned that an 8 ft span is too much for signfoam without being supported.
- What method for hanging the sign would be the easiest (we can't have any fasteners show from the front)
Thanks for your help! -Keith
