Tacky silnylon tarp issues

Quick guess, but I imagine the PU coat is breaking down.

Possibly the previous owner has "treated" the fabric with some spray.

Unlikely – afaik MLD only sell the tarp in silnylon and Cuben.

so…PU degradation might not be out of the question? Roger knows a LOT more about fabrics that I do tho.

I'll look at it closely this week when I'm hiking. It sounds like it's probably-not-but-could-be a coating degradation issue. Hopefully it's just something like a tree sap that got stuck to one section and isn't really visible but still leaves residue.

Yeah, PU degradation is a long shot, but still possible. A lot of sils have a little PU on them.

I admit I'm completely unaware of how much MLD has on theirs if any though :)

If you want to get rid of it, try patting on some powdered chalk or baby powder. I do that to the seams after seam sealing to keep them from sticking as the silicone glue is a little tacky even after drying. Even after washing away the excess the tackiness will be gone.

Could be the previous owner used it under trees infested with some sort of insects which excreted excess fluids fro their GI tract, which would leave the tarp a bit sticky.

I like this theory the most.

What about…whoever did the seam sealing may have dribbled a little sealer on the tarp panels.

set it up in sun for a few days

or hang it in warm place for a few weeks

I have fabrics which have a silicone coating on one side and a PU coating on the other side, but I have never heard of an actual silicone/PU blend. I guess its possible. Mind you, I have seen a silicone/polycarbonate blend: it was used on some spinnaker fabrics which were very noisy. The coating cracked and leaked.

I was going off the techie comments on the page for the tarp. Who knows?

Someone better ask MLD.
