I have never done a wall mounted HDU sign. It will measure 2ft h x 20 ft long. It will consist of 2 10 ft panels. When we make the HDU signs , that are hung between posts, we back up single sided with MDO, or double sided we sandwiich 3/4" MDO in the center..
My question is, since it will be 1.5" 18lb, mounted up on a masonary wall, should it be backed with MDO or Diabond (to ligthen the weight).

Diane...Diabond for sure...MDO is so heavy and will not hold up over time as well...and why aren't you using diabond as the center of your double sided HDU signs as well...much lighter, as strong as you will need, and will not decay...you can chose either the solid core or corrugated...either would be lighter and better than the MDO...checkout my last post of about a week or so ago...I included some pictures...these show an example of the corrugated version I am presently building...but I would be fine with the solid core as well...it's just that the corrugated version is so very rigid yet so super light...you might want to read what I said on that post...it could help explain more.
I would be interested for others to weigh in on this question...does a 1.5" single sided 18 lb HDU sign mounted on a wall need the extra backing...I have put unbacked HDU signs on brick at least 3 times I can remember...and probably several more that I just cant recall...the results has been fine so far.
Without knowing your particular case...there could be an advantage to backing the 2 pieces together as one...but you could consider bolting a simple 2x4 frame to the wall...you would then bolt through the HDU into the wood...I don't see backing it as completely necessary but naturally it would strengthen the sign.
Now I've spent way too much time on the computer...it's back to the tv to get caught up on Zimmerman case.

I would not back it up at all. Just attach with enough screws to hold. Works great so far for me.

I assume the sign is all one piece. The sign is going to be a bit wobbly and hard to handle. What I've done is to cut two or three slots in the back of the sign along its length and epoxied aluminum angle into it. It gives it enough rigidity to make handling easier. And when possible, in mounting to the wall I use TapComs run through the face of the sign, through the aluminum angle and into the wall.
My mind wanders. And that's not a good thing, 'cause it's too small to be out there alone. Posts: 3129 | From: Tooele, UT | Registered: Mar 2005
