Sticky tape

Have you tested it with solv weld? You might be in luck.

Gaffa is just duct tape without decent stick.

That's the sort of left field thinking I like, ta. Not sure if the stuff is actual PVC or not; definately one of the "try an inconspicuous corner" to watch it crinkle up to nothing ;-)

Funnily enough I read that after posting. Never really twigged the difference, although chances are I've never played with proper gaffer tape. Although it might explain a roll I had to use once that didn't stick well to carpet.

If you use a ds tape make sure it is fabric reinforced otherwise it will stretch as you pull it off the roll and then contract later and make the screen cockle.

Ta, good info. Tho I've no idea where to go for it; Screwfix's selection is limited.

I think I'm going to break out the sewing maching and try a piece...

Strange, all I've used have had a paper backing to stop them sticking to themselves and that has stopped the risk of stretching.

My experience of flexible PVC is that the glue on any kind of adhesive tape ends up turning gloopy or eventually slimy due to migration of the plastic iser used to make the PVC flexible into the glue; most of the joints I see that were made in the manufacture of these things seem to be welded. In the short term double sided tape should do fine but if it needs to last you may have to be prepared to remove it and re-do the joint at some point when the glue has lost too much strength.

The backing is paper but the glue is impregnated into a coarse woven fabric. At least let the tape relax a while after taking off the reel.

How about a simple sewing job, probably zig-zag stitch to minimise risk of tearing along the needle holes?
