Seam sealing NANO tarps

Why bother?? The tarps aren’t big enougth to provide protection by themselves, thus you need a bivy sack. Since the bivy protects you from spendthrift, I say forget the seamsealing and dont worry about it.

I was told (via a customer support request on this site) that silnet is fine for the nano fabric. This was for a nano stuff sack.

“Spendthrift” —- good one. If you add up the cost
of the tarp and bivy it does indeed protect you
from spendthrift. And baby needs a new pair
of shoes.

The nano tarps only significant seam is at the
ridgeline and is unlikely to leak unless you were
to set it up in an unusual way which would allow
water to pool over the seam.

I would set up any new shelter in
the yard (good practice anyway) and hose it down
to check for any leaks. Seal only if you find a spot
that water drips through. Different fabrics have different “self healing” properties and some may
need more or less sealing depending on how the
fiber and coatings enlarge or stretch back over the
needle holes. Use may have an effect on needle hole sizes too.

I find that regular Seam Sealer 3 or any similar polyurethane type sealer works fine on the thread seams. However, I do not stitch the ridgeline seam and use a double wide strip of special tape and then seal those edges with a quick swipe of Seam Sealer 3.
