A Kayak can be expensive and both fiberglass and polypropylene kayaks have been virtually impossible to repair. Tech-Patches (patent pending) will repair both types of Kayaks quickly easily and permanently. Tech-Patches are made of a reinforced polymer, are flexible and impervious to thermal cycling. Of course, they are also waterproof.
How to repair a hole or crack in a fiberglass kayak.
Need: A Starter Kit.
- Rough the area around the problem in the Kayak with a coarse grade of sandpaper (60 grit)
- Clean the roughed area with a residue free cleaner and a soft cloth.
- Spray the roughed area with a solvent-based Activator/Accelerator. Let the Accelerator dry.
- Apply a Structural Cyanoacrylate to a Tech-Patch, leaving the corners free.
- Grab opposite corners, gently stretch and press the Tech-Patch on the roughed area.
- Grab the remaining corners, gently stretch and press.
- Apply the Structural Cyanoacrylate to the corners and press down.
- Run a bead of the Structural Cyanoacrylate completely around the seam of the Tech-Patch.
- Spray the seam with the Activator/Accelerator.
