Go to the NRS site and download the instructions for a Hypalon repair. Then order Clifton's 8488 glue and accelerator. Use the accelerator very sparingly. A few drops will do ya. You can thin it a little bit with Toluene. DO NOT SEW.
Make inner and outer patch 1 1/2" to 2" wider and longer than the repair. If you have to, make the cut big enough to work inside the tube as you need to lightly grind the fabric on both sides to get both patches to stick. Prep is everything. DO NOT overgring the fabric. Just enough to roughen the coating without hitting threads. The best thing I have found to do this with as a cordless drill and scotch bright discs.
Give everything (inside and out) a coat of glue and let dry overnight. give it a second coat and start sticking it together from the inside out. Use a little bit of toluene to seperate the material it it sticks down prematurely. Good luck.
Great info here, but just want to clarify that Stabond is great for several different fabric applications. You can most definitely use Stabond on Hypalon and it's the only glue we stock and recommend for our boats. It's a very versatile glue that can adhere different fabrics to each other...for instance, our thwart attachments are plastic, but adhere to our Hypalon thwarts and boats. If you use it, you'll want to clean with MEK rather than Toluene. We stock and sell both.
If you are simply doing a Hypalon to Hypalon repair or say gluing on a d-ring or footcup, then Stabond OR Clifton will do great for the job.
