Coro vs. Plywood for Poster Projects

Recommended Posts

I've been doing a "retro" display for a few years now (mainly featuring blow molds) and I would like to try a cutout project for the upcoming season.   Since my art skills are none, I am leaning towards the already printed/glue them on/cut them out type projects and I like this classic one:

I was wondering if anyone had done this type of project using Coro instead of plywood.   I realize there would be trade offs (coro requiring some additional bracing comes to mind) but the lower cost of the coro, the easier cutting, not having to sand, etc. makes me want to explore it as an option.

Is this feasible?  Can you glue poster paper to coro?  What other problems/challenges would there be?

thanks

If you go with the thicker 10mm coro, the stuff you normally see in HomeDepot and campaign signs is only 4mm, you really won't require much bracing, if any.  My 6'x6' snowglobe is 10mm coro and  has one 2" stip running down the back, mainly so I can ziptie it easily to my pole.  I use PVC tubes on the back of my little stuff and just slip it over wood stakes or 1/2" PVC over rebar.  There are two big advantages to coro over plywood, completely weather resistant and very light weight.  The con is prepping and getting paint/glue to stick to the plastic.  I have begun using Liquid Nails Fuze-it http://www.liquidnails.com/products/fuze-it-all-surface-adhesive as my glue of choice for just about everything.  It is excellent on coro as it stays slightly flexible and adheres very well to it..the con is it is grey and too think to use to lay down the poster image, but use it to glue any bracing or mounting.   The problem with coro is it is resistant to chemicals so you aren't going to find any epoxy or anything that will chemically adhere to it.  The flexibility of the fuze-it is great as it can flex with the coro and won't crack off the surface.

To get the poster to adhere I would just lightly sand the coro to give it texture for the glue to adhere to.  I do this and then spray with krylon adhesion promoter before painting and have had good success.  For the poster you are doing I think lightly sanding the coro and using a spray glue would work just fine.  I hit my painted stuff with a clear semigloss spray at the end to seal and protect it.

If you haven't done any work using Coro, I've made a video that shows you how to make a Christmas display piece (out of Coroplast) that you might find helpful.  http://www.planetchristmas.com/index.php?/forums/topic/61350-coro-vs-plywood-for-poster-projects/#elUserLink_menu 

Hope this helps and good luck with it.  And most importantly, PLEASE post pics of your finished product!
