Aquaseal sealants from McNett are great for repairing waders and materials, including breathable and neoprene waders.
We carry the following McNett Aquaseal Repair Adhesives:
McNett Aquaseal Urethane Repair Adhesive repairs all types of waders and materials, including breathable and neoprene waders. This sealant provides superior adhesion, wear resistance, flexibility and waterproofing. Aquaseal features a highly concentrated formula, providing a thick layer to repairs with minimal adhesive shrinkage. One application to waders provides a permanent waterproof patch. Aquaseal Urethane Repair Adhesive comes in a resealable 0.75 oz. tube with instructions.
McNett Aquaseal UV Ultra-Violet Cure Repair Adhesive repairs all types of waders and materials in the same way as the Urethane sealant with the addition of UV curing, which enables you to perform streamside wader repairs. A few seconds of exposure to the sun or to a mini UV lamp and the wader patch is cured. One application to waders provides a permanent waterproof patch. Aquaseal UV Ultra-Violet Cure Repair Adhesive comes in a resealable 0.25 oz. tube with instructions.
McNett Cotol-240 does two things to make gear repair better. It is a urethane cure accelerator as well as a pre-repair cleaner. Cotol-240 speeds curing time to approximately 2 hours and eliminates surface contaminants that inhibit adhesive bonding. Cotol-240 is formulated for use with SeamGrip, Aquaseal Urethane Repair Adhesive and Freesole. Comes in a 0.5 ounce jar with applicator brush.
I have used this product a couple of time over the years. Once for a silver dollar size hole in neoprene waders, It worked great. This time I bought a couple tubes one to repair a cut in the rubber boot portion of my waders. And then I used the rest to cover all of my seams. Not that they were leaking there but just for some preventative maintinance.
A little tip I dilute with a little thinner and use some acid brushes to give the seams some good uniform coverage.
