Franco. love the music. Nice video. Could you show us a close up of the job done. I just finished doing my Duomid. It's in the yard being tested as it is raining again.

Hi Ken
This was all done very quickly. One take and it is live video.
I just grabbed some detail from one of the last frames from that video. You should be able to see the sealer trickling down from the paintbrush. It is , at this stage, very runny, about the consistency I use .
I never measure the mix , just go by feel.

There was no tent to seam seal. I just did that to show how simple it can be to dilute silicone.
As for why, see , for example, page 2 of the "silnylon misting" thread, my comment there.

Ken,
Here is a Spinn seam, with bivy loop stitching at the center. My silicone was about the same consistency as Franco's. I applied it with a syringe. When I flip the tarp over, I can see the silicone has wicked through.

Perfect timing. I am about to go get some silicone for a new GG Spinn Shelter. Never was accurate with the 3 to 1 ratio measuring. Thanks for the video.

Excellent, thanks for the video! Is it considered a requirement to later powder the seam with talc to prevent it from sticking to itself when packed?

Some do, I don't. Mine stay up for at least a day and a night ,usually 2 days.
A few years ago i did the whole floor of a BD tent and put that away when I thought it was completely dry. Sometime later I put that up to find that a wrinkle on the floor had stuck to itself.
Unfortunately, having left my brain upstairs , I proceeded to forcefully separate the fabric. I now have a patch on that floor.
So, take your time…

If you're short on patience, or have a sore wrist, a slightly bent finish nail chucked in a drill will stir up a uniform batch in a few seconds.

When I first posted this method, a guy said it took longer to get out the drill than it does to mix by hand, and he didn't have the money to spare for a nail. So, depending on your drill storage and financial situation, this may not be the solution for you.

Worked like a charm for me though.
