Would it be the same glue as used for plastic model kits? If so, search Ebay for "airfix model glue"
Solvent weld for PVC drainpipes. Comes in a big tin for not much money - compared to most tubes of such stuff. You'll have to ask for it in a shed
- obviously a 'sniffer' favourite. Or go to a proper PM.
no it is NOT the same. That is styrene, the OP wants polyvinylchloride
Thiod is readily available at any builders merchants as the stuff used to bond PVC plumbing and guttering. Its essentialy PVC dissolved in (probably) xylene or similar.
You can also make it using cellulose thinners and bits of chopped up PVC.
Something containing Methyl ethyl ketone might work, Methylene chloride is a solvent that will work.
Will it work as well on flexible PVC?
I have some already so I'll try! :-)
Assuming it 'welds' that variety, I don't see why not.
Best way.
What he said. I've used it to fix all manner of PVC objects. Also available in smaller tubes which may be better for occasional use.
