Thread: sikaflex fc11 for breathable wader seam repairs and sealing???

I've been told that sikaflex fc11 is a way more cost effective - and just as good - solution for seam sealing breathable wader seams where they have started to leak. I used a $30 tube of stormsure, which seems good, but on 2 sets of waders, would cost about $240.....
Hence thinking to try the fc11 at $30 for a full tube. I'll try it on some cheap Scierras first.
Anyone had experience with it? Wondering if it needs to be diluted at all.

Had plenty of experience with it, not in your application though. Not a product you can dilute, for ease of application keep it warm 20 - 25 degrees will make it far easier to use than if cold. It's a good quality product as sealant/adhesives go. There are some others out there that may work as well if not better as the technology has improved from 11FC (polyurethane) to products like Bostik Safe Fix or Fixall High Tac (MS Based).

Good idea to trial on something cheap, it will be hard to remove if it works.

Thanks, OK I won't thin it and will give a small patch a go first.....

I used the marine version Sika 291 to repair rubber product, wetsuit and even better 3m 5200. It’s not pretty but bulletproof

I'll track some of that 3m stuff down and try that. Thanks. Good to see you sorted your PRC issue eventually - interesting.

Yeah took a while to sort… Burnsco has small tube I think.
