Sign construction advice

[Circleville Signs]

OK - Here's my dilema - and I know there is probably an easy answer, however i've not ever tried this before with Polymetal/Dibond.

I've got a sign completely made out of 6mm Polymetal. It is 3'x6', or at least the panel is.

This panel has a full digital print piece laid down on it. I need to attach some routed shapes to this face, that are also cut from 6mm Polymetal.

Here's the kicker - they need to be flush, AND I can' have bolts sticking out of the back of the sign, as it is single sided, eye level post mounted.

Oh, yeah - and one layer of the routed shapes sits on top of another one, but is larger - so I'm going to have to anchor it with some type of spacers, I'm thinking?

Will gorilla glue work for this? I'm worried to use silicone because I won't be able to get things flush.

Any suggestions are appreciated!

I would probably use laminating adhesive sheets for that...my brand of choice is mactac IB-2107 comes 17"x22" sheets

silicone done correctly would be flush...just weigh it down

 

[Circleville Signs]

Will the adhesive on those sheets be strong enough to hold up a shaped peice that weighs, say, 3 lbs?

 

[J Hill Designs]

I would say so...It's full contact across the entire surface...I can test with a heavier than 3 lbs setup RQ if you want...

That would be awesome if you don't mind!

Thank you for this thread!

We have to do a similar layout using 1/4" dibond, with raised 1/4" dibond panels with the renters' business names on them. Is the MacTac sheets good for an outdoor application?
I found a spec sheet on it but it does not specify.

how thick is your base piece and lettering?
i've stud mouted 1/8" to 1/8" before without having the studs sticking out either side... paired with adhesive of any kind, they'll never fall off.

OK approx 5lb - 1/8" aluminum sheet attached to dibond - not only does it not fall off, I am having a hard time releasing it with force

as for exterior, I can only imagine yes since its a PE core with acrylic adhesive...water/solvent resistant

Sweet man!! Just ordered some of it and will post the finished sign once I pick up the sheets and get it finished!

I'd use 3M VHB tape

Great thread!

 

[J Hill Designs]

most VHB is too thick to not see a visible offset from the surface..and the thin stuff (I have found) doesnt quite work that well

What about a nest rout were the panels will be placed? Then they could be glued/silconed into the inset.
