I recently bought a Big Agnes Fly Creek tent. It is a great tent; I have had it out twice now and have weathered a couple of strong rainstorms in it and stayed bone dry. I like the weight; 35 oz with stakes, lines and thin Tyvek ground cloth. Only a few ounces more than the single wall Contrail it replaced. I like the double wall feature and it seems to be roomy enough for me at 5' 10" tall, 170 lb.

My only problem with the tent is a low coefficient of friction between the tent floor and the bottom side of my Thermarest Prolite 3 short sleeping pad. I contacted Big Agnes and they recommend patches of McNett Seam Grip on the floor. I suspect that silicon sealer won't stick to the polyurethane. Any other recommendations or ideas? Thanks!

Silicone will stick to the silnylon. I painted a cross hatch on the floor of my Contrail. I used silicone caulk thinned with Coleman fuel per the instructions with the tarptent. Really makes a difference. The pad stays in place much better.

The Gossamer Gear 1/8" thinlight pad is another option, to put between the Prolite and tent floor. It won't slide against either surface. Also multi-use if you need extra insulation or a sit pad, but an extra object to carry if you don't.

second vote for either the mcnett's seam sealer, or use 100% silicone caulking thinned 50/50 with white gas and paint it on.

Ditto. I did this on colder trips with my prolite 4 short.

Also, If you don’t want to mess up your tent, an 8x8” pad of shelf liner (~1oz) holds thermarests pretty well.

Shelf liner works well. I use it between my thermarest and my sleeping bag. It keeps me from sliding off.

Pardon my ignorance but I don't think I am at all familiar with shelf liner and certainly never thought about it as a non-skid surface. Is it that flowery peel off paper that folks use on kitchen shelves? Sounds fascinating and it could substitute for a bouquet in my tent. How is it applied? As strips or blocks or patches? How well does it adhere? Any info would be a big help. Thanks.

I think Howie is referring to this stuff.

Thanks for the reference. Looks good but I was hoping for flowers.

The floor of your tent is described :
"Floor is ultralight silicone treated nylon rip-stop with a 1200mm waterproof polyurethane coating "
I would assume that if top part (the inside ) feels slippery, then only the outside is coated. In that case you do need silicone seam sealer.
My suggestion is to paint "dots" rather than stripes so that the dirt does not get trapped in between when you try so sweep it out.
(you also use less silicone this way)

Buy a tube of GE Silicone II, clear. Wipe down your tent floor to get the dust off of it. Put a small dot(the size of a BB) of silicone every ten or so inches. It will flatten out as it cures. You don't need many dots and you don't need to thin it. Phat's 'paint on' idea works too and with that you will need to thin it a bit.
