Good Coroplast to Coroplast Adhesive?

I want to patch up some "oops" and bond some lap joints together. What's a good glue to hold this stuff to itself?

I'd give super glue a try.

I was wondering that very same question.
I was going to try using 3M spray trim adhesive (I have 2 partial cans on a shelf) That stuff seems to be able to hold just about anything to itself.
My other thought was to carry some coroplast to the craft store or home depot and ask them for advice.
And now a 3rd thought, asking the people who sold me the coroplast in the first place. They ought to know.

I'd try liquid nails or possibly gorilla glue.

I've used contact / rubber cement with coroplast (once). Worked well for me.

Coroplast is made of polyethylene, so you need to use one of the few adhesives that will work with polyethylene, which is a low surface energy material that most glues will only attach weakly too. If you are careful, (since coroplast is hollow) you can also heat weld pieces of it together. McMaster-Carr sells an epoxy adhesive that works with polyethylene.

Walmart sells a 2 part glue (primer + glue) that says it works even with polyethylene. I know it is rare to find one that does work. Honestly Id try contact cement first, it seems like it would work a lot better for large surface area lap joints.

Thanks for the info. on just what coroplast really is, basjos. I found some information about bonding polyethylene by googling and found this writeup about a specialty 3M product, DP 8005:


He talks about the special applicator -- I'd give just squirting it out on a piece of cardboard and stirring it up a try. It looks like it's available at "drillspot.com" here:


With ground shipping a single tube is about $25.00. I may want to live with my ugly lap joint for a while, or even try some really short sheet metal screws run in from the piece behind the visible surface to see it that's good enough for a while.

Edit to add: Sheesh, thanks again, basjos, for the McMaster-Carr reference. I'll see if the outlet near me stocks the stuff.

you should try fiberglass resin on a sample piece.. bet it would work, there are different types of resins that are compatible with different types of materials..

Really i love fiberglass resin there are so many uses for the stuff.
