3L seam tape. 22mm wide, use with any 3L WPB fabric.
Apply with a normal clothes iron at 100 degrees with a teflon sheet or baking paper to protect the iron from glue. Even white side has the glue surface. Power output on irons and material compatibilities may vary so try with scrap pieces first.
Meant for waterproofing sewn seams. Not to attach fabric.
You can also cut the tape narrower to fit on tight seams.
