"Mike Lyle" wrote in message ... Perfect logic, but the fact remains that there isn't a glue for poly[ethyl]ene, which isn't a million miles different from ptfe, the non-stick frying-pan stuff. It's always joined by welding. The problem is, I think, that the adhesives on gaffer tape and such-like, while they will stick well to polythene till they dry out a few years later, can't be applied in amateur conditions. -- Mike. Yup -but we are talking about repair -not construction. A repair using the proper tape will outlast the useful life of the poly sheet. imho ! pete |

Yes, that's quite right; but I was only answering the question about why we can't get an adhesive which would work for polythene. |

Yup -but we are talking about repair -not construction. A repair using the proper tape will outlast the useful life of the poly sheet. But would have been impossible. Given two edges 12" apart, taping it up just isn't going to work. Lacing it up, and drawing the edges together worked well. However, the proper tape does well with intermittent loads, but will creep off the joint if it's under constant tension. |
