Hi,
I've just finished making a some silnylon stuff sacks and used SilNet to seal the seams. I then tried to inflate the stuff sacks (ala Jardine's beachball description) and while each inflated, they lost air fairly quickly.
I know this can't be THAT technical, so what am I doing wrong? Here's what I did, any new techniques would be appreciated.
I cleaned the seams with alcohol (from the medicine cabinet).
I let it dry.
I squished out some SilNet onto the seam on the OUTSIDE of the bag, and pushed it around, trying to "push" it into the seams, as Jardine described. I squished more, until it covered an area maybe 1/4 inch on either side of the seam (on the OUTSIDE of the bag), and seemed to be a consistently thick layer right over the seam. It doesn't "glob" over the seam.
I let the whole thing dry for 24 hours. Then I tried the beachball test and failed. :-(
I have filled the sink with water, and found that there is no consistency to where the leaks are, it's not just the corners, nor is it the whole length of the seam.
Any words of wisdom for the next batch I try to seam seal? And, I'm assuming I can just put a little more alcohol on the leaky bags, and then more Silnet, but again, any suggestions would be helpful.
I'm sorry if this is a really stupid question... you should have seen me paint a wall the first time. Sheeesh.
