Stormsure is suitable polyurethane glue for packraft patching. Fixing small holes and resolved seams works nifty at home.
If the damage is in an awkward place (e.g. seam), Stormsure glue is best help for it. Clean the surface (with alcohol if possible), dry well and spread liquid Stormsure glue to the damaged part. Spread the glue at least 5 mm over the end of the damaged part. Glue flattens out itself. Stormsure glue dries approximately in 10-12 hours. Stormsure is polyurethane, very flexible and 100% waterproof.
You can also use stormsure for tents, waders and other things made of polyurethane and neoprene. This is not contact glue, so with this you can not glue for example grab loops – for that you need contact glue made for polyurethane. Package contain: 15 g tube clear or black Stormsure glue.
Note: Manufacturer recommends to store opened Stormsure glue in a freezer.
