I’ve seen posts here on BPL that deal with applying a diluted silicone onto silnylon that’s losing its waterproofness.
Questions: 1) which silicone is best? 2) what is the best diluting agent? 3) what is the most effective tool for applying the mixture, a brush or something else?
Also, can this process help increase the hh of new silnylon? Thanks

100% silicone, for example GE. Clear. Don’t get the version that has mold inihibitor or dries quickly.
dilute with mineral spirits. Don’t get the low VOC version or environmentally friendly version, it has stuff other than mineral spirits.
10:1 by weight, stir for several minutes until the silicone becomes uniformly mixed.
Foam brush is good.
If your silnylon has lost its waterproofness, has it also lost it’s strength from UV? The color starts getting faded. If you really pull on it it will rip.
Set your tent up so it’s really taut, apply, let dry for at least a day. You could do it to a new tent which would increase it’s waterproofness. Also give it some UV protection.

I did one shelter using a very highly diluted mix (something like 10:1) but it was still too much.
