What do you glue carpet down with? I have a few veritical areas in the cabin.

Thanks,

Depends on what kind of backing is on it. If it's light weight carpet with foam backing you can get by with spray adhesive. If it's heavier with a more course backing you may need carpet adhesive. You can get either at Home Depot.

I'm by no means a professional carpet layer, but I've done a number of DIY jobs on cars and boats. I use a good quality contact adhesive, not sure what brands you have over there but I've used Kwik Grip and Bostik contact adhesives. Just brush it onto both surfaces, let it go tacky and bring them together. Never had a problem with it lifting.
I even carpeted ply this way to deck in my boat trailer. 4 years on and it still looks like the day I did it.

thanks!
