: Hello Again Sage,

: If you are sealing PVC to PVC then there is a glue that you can buy at any
: good marine chandlery. It is used to patch hypalon inflatable boats, which
: is basically PVC. Make sure it is compatable with PVC. I'm pretty sure
: that hypalon has a rubber coating and the glue may be different, but I
: think the one I bought does both.

I do believe PVC and Hypalon are two different things...Hypalon is rubber (or synthetic rubber?) based. PVC (polyvinylchloride) is "vinyl" based.

I would be interested to know what brand you used. Sounds like it might be a good "universal" adhesive.

For structural joints, it's probably best to use an adhesive specifically formulated for your fabric.

PVC's are "solvent-welded", which means the fabric is slightly melted to form the bond.

I think rubber cements (for true rubbers) will use some sort of unvulcanized rubber which vulcanizes with the addition of heat or a catalyst.
