Seam sealing

BTW, yes at TT USA they use a thinner version than the one I use.
Sometime it is hard to tell their work (except against the light) , you can see mine , still it is thinner than most.

Thanks for the clarification on the different application. That makes much more sense.

So, that TT USA method also works? Any reason why you prefer the slightly thicker consistency? Durability? Convenience of application? I've done mine closer to your suggested consistency. It's thin enough to not peel off with some finger rubbing yet visibly forms a layer on top. Assume that's good.

Just personal preference. (I use the seams as sort of built in guylines)
I put more tension than some on my tents and that is partly how I do it.
Brooks Range use a variant of this in their Tension 30 tents (inner seams with built in cord ), Aarn Tate and Jack Stephensons have their versions ( X tension inside via cords) , not of course that my idea compares to theirs..

Thanks for the insight Franco. Makes sense.

Franco, I understand that you'd use a more dilute mixture for "proofing". But 100 to 1? How much silicone per square meter would that work out to?

I think I used something closer to 4:1 when I de-slipperyized the silnylon floor in my summer tent. I probably overdid it a bit but it's still good 8 years later.

Orion you have to remember that this 100:1 dilution was used over the top of the existing PU proofing layer on the Moss tarp.
The mixture I used for waterproofing the Megamid was probably closer to 20:1 and doing inside and out added ~200/250 grams to the weight. Not really sure because I never bothered to weigh either

Interesting. I didn't know silicone would even stick all that well to a polyurethane coated fabric.
