In my old railway modeling days we used PVA, what's the application, stresses on the joint etc?

Use epoxy. 5 minute stuff is more than strong enough. It won't melt the foam, and unlike PVA, it doesn't require air to dry.

Silicone sealant works well and is totally waterproof.

Superglue?


Was that a joke????

You'll have no polystyrene left....

UHU POR does it nicely, so does PVA, and so does FoamZap.

do you remember my working narrowboat? it just has a platform at the top of the hull covered with a thin layer of coal, underneath can be hollow, or in my case all the radio and batteries are below.

I suspect you might be confusing polystyrene foam and polystyrene sheet. They have rather different properties.

Unless it's blue, pink or EPP foam you're using, no they don't.

If you are, none of them are called polystyrene.

You are obviously far better informed than I am, and indeed than the people who contribute to Wikipedia: http://en.wikipedia.org/wiki/Polystyrene

you can use superglue, any superglue on polystyrene, polystyrene is the sheet plastic (for some reason known as styrene sheet by a lot of modellers), obviously you can use MEK weld or polyweld plastic cements as well

On EPS (polystyrene foam, expanded polystyrene, white foam( and most other foams)) you can use odourless cyanoacrylate (foam freindly superglue) (not the standard types), foam safe contact glues such as our Depbond (solvent based) or Depbond Pro.W (solvent free), PVA and Aliphatic resins are slow to dry but can be used on small areas , epoxy resins can be used with no problems as they have no solvents (never use polyester resin) , Most foaming polyurethane glues such as Xbond can be used as well
