Customer wants Dibond over MDO (don't ask) What would be the best way to fix the two together - there's no folding so I'm thinking some kind of adhesive. Silicone? Epoxy? Do you think there would be any expansion/contraction issues between the two materials (4'x8')?
Any advice appreciated.

I've laminated both sides with Dibond and haven't seen any expansion issues yet. I don't know if one side only would cause a problem.
We use Gorilla glue, laminate to both sides, clamp to dry, then route or cut through all to get a flush edge. Seal and paint the MDO edge as you normally would.

Dave,
If I told you, I'd have to kill you Posted by Michael Boone (Member # 308) on :
why would you not use aluminum instead of Dibond....it would be a lot cheaper and just as good.....

5 years ago, I put a new aluminum sign face (.040") over an existing MDO sign. I cleaned the MDO with 440 Wax and grease remover and used 3M high bond Tape! It is still there, with no signs of coming loose! I agree with Boone. Why use Dibond???

Because the customer is always right. If you use aluminum is it big enough that you might have trouble with oil canning? I say use roofing screws, that way he'll be able to see it is on there good and he'll have confidence in the project Posted by Graham Parsons (Member # 1129) on :
They want Dibond because they want the colored finish (Blue) to exactly match their other signs...(and the cost isn't an issue)
