Atsko Silicone Water Guard 300g

G'day Belle,

Theres no coverage of application rate provided by Atsko at all, but it is a super light application.
You're not supposed to soak the fabric or put a thick coating on it.  Some customers have done a full gazebo fly with one can, so you'd be able to get a hiking tent or smaller tent done, or a few jackets, etc.

G'day Jack,

Yes, you could use this spray on your hiking pack. We don't sell Osprey, so it's hard to know for sure if it would have any impact on the mesh you're talking about, but the spray is designed for nylon and other synthetic outdoor fabrics so as far as we know this should do the trick.

G'day Ali,

The Atsko Silicone Water Guard spray will definately be suitable! The Nikwax Tent & Gear Solar Proof will also do the trick, with added UV protection to help prolong the life of your fly.  In terms of rejuvenating the water rating, either will do the trick!
