    We need to make some temporary road-side signage for an event. We are going to print 4ft x 8ft graphics on vinyl using HP Latex and then adhere them to either ACM or Coroplast... Do you all have tips on adhering the ACM or Coro to Plywood or OSB? I wasn't sure if it would be better to use something that rolls on or that you squeeze on (like liquid nails). Any tips would be appreciated!

    Fasteners would be what I'd use. If you used 6mm you likely don't need the plywood backer. If you use adhesive, I guess I'd trust something with some thickness and flexibility to it, rather than something you roll.

    texas signmaker is tight, nothing wrong with a few fasteners
    we have short deck screws & fender washers painted to "normal" colors (black, white, red, blue, green, brown, etc) . choose a solid colored area on your print. strengthens your liquid nails, construction adhesive or whatever

    The price is high right now for MDO. Not sure if there is a shortage due to political signs or what but that is why I was thinking of using the Coro on OSB option.

    Yes, that stuff is very nice but very expensive for a very short term use.

    I am afraid it would be too light and flimsy for that large of a sign and the wind would cause it to buckle. However, if a wood frame was made behind it then that actually is a good idea but I would have to see if it would be worth the time to make a wood frame. Thanks.

    If it's available in your area- I use 10mm Coroplast often in place of MDO for site/ political signage faces with great results. I get a couple of 2x4" stringers across the back to support it if need be and it's a done deal. Granted the posts are painted and the auger doesn't hit hardpan it's a 30 minute install with 2 gents. Best of luck with your project!

    If things are too expensive, why waste YOUR time building frames and whatnot outta cheap substrates ?? They either pay for what they want and you give it to them.... or they pay extra for your extra time. Building frames to support a cheap Cor-X sign is ludicrous, just because they don't wanna spend any money. How much time do you already have invested trying to figure this out ??

    Use $35 3mm ACM and two stringers between your post and call it a day. Or if you dont have a flatbed, print on banner at attach w/ fasteners w/ grommets

    He may be tight.
    But fasteners work best.

    I'm gonna go out on a limb here, but I think netsol meant right, not tight, cause he repeated the same sentiments.
