Hi all,
Cascamite has been suggested as a good adhesive for gluing two blocks of craft foam together but before I wasted my time traipsing up and down isles I thought I'd ask here if the sheds stocked same?
I think the last time I used it was when I built a 6' rowing dinghy when I was at school!
All the best and thanks for your time ..

I'd not think it that good as it's inflexible. I'd try Evostick Serious glue.
Name changed to Extramite for some reason, readily available.
Ah, ok. I may have misled you there Dave. This foam is the rigid stuff, like expended polystyrene but finer? (daughter has to glue a couple of sheets of it together to make a thicker block to then turn / carve into shape.
Would 'serious glue' still be ok for that (didn't know if it was solvent based and may eat that type of foam)?
All the best ..

Ah, I spotted some of that on a Google search but wasn't sure it was the *same* stuff (like the difference between a generic 'No-more-nails' and green Gripfill) ;-)
All the best ..

I wouldn't use cascamite.
Or any other hard setting gap filling type glue.
No more nails or just PVA is the better sort of air dry glue.
Not sure whether I have some, but a water based contact adhesive may be best.
Mmm...I'll see and report back.
Right. I picked some up a few years back..Dunlop Thixofix ECO. Its a solvent free contact adhesive.
I've spread some on some white foam to see if it sticks OK.
I'll report back shortly when it dries ... and I whack the two bits together.
Right. It took ages to dry to tacky, BUT it's made a fantastic joint..
Eminently sand-able.
Ah - right.
It doesn't appear to eat into things in the same way as Evostick Impact, so I'd guess any solvent is less aggressive. But like all these things unless you're certain what the material is and what glues it best to do a test.
typically blue foam as used under concrete floors. Its extruded into flat sheets, and has a higher density and better surface finish than white.
the only solvents I have found that DON'T attack polystyrene are alcohols. And straight hydrocarbons like petrol and diesel. Any of the more usual solvents kill it stone dead. Acetone, cellulose thinners, etc.
Hence m advice to use a water based contact. Water based air dry stuff works, but takes forever to set off due to the impermeability.
Axminster sell it, not sure if it's right though
Brilliant, thanks for the field report ;-)
Same question then, is it currently available in the sheds?
All the best ..

No idea..copydex is another similar one.
