I want to bond flexible PVC/vinyl sheeting to itself and I'm having
trouble identifying which of many products I can find actually do this
properly by 'welding' the PVC. I.e. I want a glue that actually
dissolves the plastic slightly so that the two pieces merge into one
piece.

I tried some Bostic "Soft Plastic" adhesive but that just does a
moderately good job of sticking the two pieces together. If you pull
the joint apart both halves are entirely unmarked and you can peel the
adhesive off the plastic.

There's a product called "HAÂ*66 Vinyl Adhesive Glue Cement" which
*sounds* like it should do the job (available from an eBay supplier)
but I'd like to be sure before buying it as it's quite expensive.

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.

Nope.

Something containing Methyl ethyl ketone might work, Methylene chloride
is a solvent that will work.

I have some already so I'll try! :-)

SWimming pool suppliers, some hardware shop, as in a kit for reparing backyard inflatable paddling pools. I had a kit with patch material some years ago and repairs did stay repaired. It was much more expensive than PVC pipe solvent.

Assuming it 'welds' that variety, I don't see why not.

Best way.

Of course. All these products sold for a specific task are. Even although
the basic chemistry is identical to something else. Think kettle
de-scaler, etc

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.

Can't see any tubes there and half a litre is a lot. OTOH a 50ml tube from
my local plumbers merchant costs the same price.

Got some Marley brand at my local BM in 250mL. Can't remember what it
cost, but if it had been a lot I'd have remembered. It does have a use by
date - but that seems pretty conservative.

No, similar to the Bostic "Soft Plastic" adhesive, it stuck the PVC
together but not very well. It pulled apart easily and the surface
was unmarked by the glue which could be rubbed off.

As I said I tried the tube I have (Marley) and it simply doesn't work
on flexible PVC.

Yes, I know, that's why I'm asking about it here before I spend lots
of money! :-)

Means the material you're trying to glue isn't PVC. Solvent weld dissolves
that, so would leave a mark even if it failed.

That's what I would have thought, too.
If the material here is soft then if it were PVC it would contain plasticisers, which might possibly affect the bond strength - but I'd still expect PVC solvent cement to leave a mark.
