I bought some 'PSP Spinnaker repair tape'. Washed the troos and made sure they were dry. Cut two strips of tape with rounded corners, applied tape to garment and pressed hard with a cold iron. The tape doesn't seem to have stuck that well. Is it my method of application, the tape or a combination of both leading to a non-satisfactory result?
I had to do some repairs on my waterproofs. 2.5 drilite. Nothing much stuck including the spinnaker tape. In the end I put it down to the fact that I'd done a wash and TX job on them recently and it was that that was the issue. Especially after using it on some other older waterproofs, where it adhered brilliantly, and another more 'fabriccy' jacket where it was like an invisible mend.
I'd say taping the inside first and letting it adhere for a bit before doing the outer as well and making a sandwich of the fabric.
On the Drilite I found some clear gorilla tape and applied it to the inside. making sure the tear was back in its spot, then after the original outer tape failed, I ran some shoo goo glue along the tear to keep it sealed and it worked. Not the neatest of jobs, but battle scars on show!
