I've been trying to make a sprayskirt using this material and am having trouble getting the curves to seal well enough.

When you are sewing the curvature where the tunnel meets the spray deck you can cut darts or just sew over the bumps or bunches in the fabric where you are talking it into curving where it doesn't want to but when using the iron on the heat seal I've been getting small folds that end up leaking water thru.

It may be good enough for a non-rolling skirt but wasn't really good enough in my opinion for a rolling skirt.

Shawn, do you have any tricks for getting the heat seal to do the corners well?

The heat seal seems to need to be laying very flat to seal well, no problem for drybags etc. but trouble for curves required for skirts.

Hi Dave,

: It is urethane coated. You can sew it, but the most popular joinery for it is
: just as you assumed--with heat from a regular household iron. Makes a
: perfectly tough and waterproof seam.

: It is great stuff for making float bags, dry bags, nylon sprayskirts, and
: cockpit covers.
