Interior: What adhesive works to glue carpet to corrugated plastic for interior work

[Jeff T.]

Good evening,

Awhile back I asked about what I could use to replace my weathered firewall liner and kick panels for my 62 Lark that sits outside in the weather year round , someone out there suggested corrugated plastic (Thanks for the suggestion)

So I have cut out a replacement firewall liner and kick panels and now I want to glue some extra carpet to the liner and kick panels but wonder if good old contact cement will work to glue carpet to the plastic on one side and apply the fiberglass batting from the original firewall liner to the flip side.

If contact cement wont work, what do you suggest?

Thanks,

Jeff

3M Super 77 Multipurpose adhesive. Spray it on both surfaces, bond almost immediately. Hot glue gun for any edges that lift. Nothing really, really bonds to Coroplast, because it is polyolefin, and does not bond well to any adhesive, but the Super 77 has a sticky-tape sort of stickiness that endures. Some staple-gun staples, shot through from the carpet side and then bent over, could help, too.

I agree with gordr. The 3M Super 77 will do the job for you. I've used the Super 77 for years with great results. Bud

While I haven't glued carpet to coroplast, I have built little boxes out of the stuff and hot glue works really well. I'll bet it works great for the edges.

Yeah. Coroplast is polypropylene, and hot glue is polyethylene. Get the Coroplast at the joint hot enough, and use hot glue, and you are actually plastic welding.

What variety of hot glue would you recommend? I've a couple of hot glue guns in the basement and a lot of plastic scraps to practice with.

I have always used the clear stuff. Maybe the package indicates what color is best suited for each use.
