The bond made with Aquasure is much weaker than welded TPU, but in this case you are not relying on the Aquasure for a structural bond, only to make it airtight where the TPU is partly damaged. I would not use Aquasure between the seam strip and the tube fabric – even damaged TPU will be stronger, so simply reheat and reposition the seam strip,…[Read more]

Thanks for your calming answer Matt, I might even get down from the ladder later on to night and give it a try. 🙂   Maby I´ll try to do it using the hot air-welder I bought but havn´t been trying much yet.

One question though, would you say that a bond made with Aquasure is somewhat to be compared with the TPU-bond, or is it much weaker?

Don’t worry – it doesn’t look too bad!

In this situation I would first remove as much cardboard as possible by heating it with the iron and scraping it off carefully with a knife, a little bit at a time (or peel it all off when it is hot if it will come off in one piece, but I think it won’t). Then reheat the folded/wrinkled area to release the…[Read more]

Good idea!

Yep, the TPU is what makes the fabric airtight, so if it’s damaged that could cause it to leak – check those spots first. Cheers!

And apparently my tablet is schizophrenic when it comes to posting in a forum and I apologize.

Thank you Bruce, I appreciate your advice. The iron came with the V3 kit I recently purchased on eBay and I’m guessing it’s, at least, unused if not new. TBH I find infrared temp sensors to be iffy at best and I couldn’t get a consistent temperature trend to save my life. I find contact thermocouplings to be considerably more accurate and consi…[Read more]

Has anyone considered coating the inside lip of the dry bag closure with sealgrip to help minimize air loss?

Have you considered using a piece of 1/4 or 3/8 pex pipe split lengthwise on one side?
