Extend your gear’s life with our top 6 wetsuit sealants. Learn which adhesives offer the best flexibility and durability for quick, professional-grade repairs.
There is nothing quite as disheartening as pulling on your favorite wetsuit only to feel that telltale trickle of cold water seeping through a jagged tear. Wetsuits are a significant investment, but they don’t have to be retired the moment they snag on a reef or fingernail. With the right sealant, you can patch those breaches and get back to the lineup without missing a single swell.

Understanding Wetsuit Damage and Repair Needs
Wetsuit damage usually falls into two categories: superficial nicks and structural seam failures. A small cut on the exterior neoprene is often just a cosmetic annoyance, but if left unaddressed, the foam will absorb water and eventually tear further under the stress of movement.
Seam failures, however, are the silent killers of thermal protection. When the internal tape lifts or the stitching pulls apart, your suit loses its ability to trap a thin layer of water against your skin. Recognizing the difference between a simple patch job and a need for professional stitching is the first step in saving your gear.
Gear Maintenance and Proper Cleaning Methods
Before you even think about applying glue, your suit must be pristine. Salt crystals, sunscreen residue, and body oils create a barrier that prevents adhesives from bonding to the neoprene. Always rinse your suit thoroughly with fresh water after every session and hang it in the shade to dry completely.
Never use harsh detergents or leave your suit in direct sunlight, as UV rays break down the rubber polymers over time. If you notice a tear, clean the area with a bit of isopropyl alcohol to remove any lingering oils before attempting a repair. A clean surface is the single most important factor in ensuring your sealant actually holds.
Gear Aid Aquaseal NEO for Permanent Seams
If you are looking for the gold standard in neoprene repair, Aquaseal NEO is the product you want in your kit. It is specifically formulated to remain flexible, meaning it stretches right along with your suit rather than cracking and peeling off after a few sessions.
This sealant is perfect for anyone dealing with high-stress areas like crotches or underarm seams. It creates a bond that is effectively as strong as the original rubber, making it a permanent solution for serious wear. If you want a "set it and forget it" repair that won’t compromise your range of motion, this is your best bet.
McNett Black Witch for Quick Neoprene Fixes
Black Witch has been a staple in surf shops for decades, and for good reason. It is a contact adhesive that dries rapidly, making it the ideal choice for those emergency repairs you need to perform right before heading out to the beach.
Because it dries into a tough, black rubberized finish, it is best suited for exterior nicks and small gouges rather than large structural seams. It isn’t as elastic as newer specialized formulas, but its speed and reliability make it a must-have for any surfer’s travel bag. If you need a quick fix that will hold up for the rest of your trip, Black Witch is the reliable classic you need.
Stormsure Flexible Adhesive for Large Tears
When you’ve had a major mishap—like a deep fin gash or a snag on a jagged rock—you need something with more body. Stormsure is a thicker, heavy-duty adhesive that fills large gaps and voids better than thinner liquid sealants.
This product is designed for high-impact durability and remains incredibly flexible once cured. It is the best choice for those "oh no" moments where a significant chunk of neoprene has been compromised. If you have a deep tear that requires a bit of structural filling, reach for Stormsure to bridge the gap.
Gorilla Waterproof Patch for Instant Repairs
Sometimes you don’t have the luxury of waiting 24 hours for glue to cure. The Gorilla Waterproof Patch is essentially a heavy-duty, pressure-sensitive tape that acts as a temporary field repair. It is incredibly sticky and holds up surprisingly well against the constant flushing of ocean water.
This should be viewed as a temporary "get-you-through-the-weekend" solution rather than a permanent fix. It is perfect for keeping in your car or backpack for those moments when a seam blows out mid-session. If you need to keep your session going right now, carry a patch kit; it’s the ultimate insurance policy.
Aquaseal UV Cure for Fast On-the-Go Mending
Aquaseal UV Cure is a clever bit of engineering that uses sunlight to harden the adhesive in seconds. You apply the gel, expose it to the sun, and watch it turn into a solid, flexible patch almost instantly.
This is the ultimate tool for the minimalist traveler who doesn’t want to deal with messy tubes of glue and long drying times. It works best on small exterior tears and fingernail nicks that don’t require deep penetration. If you value efficiency and want a repair that is ready to go as soon as the sun hits it, this is the product for you.
Seam Grip WP for Long-Lasting Waterproofing
Seam Grip WP is the heavy hitter for sealing leaking seams that have lost their factory integrity. It is thinner than typical neoprene glues, which allows it to seep into the tiny gaps between stitches and fabric to create a watertight seal.
It’s not for patching holes, but rather for reinforcing areas where the water is starting to seep through. If your suit is still in good shape but the seams are starting to "weep" cold water, painting a thin layer of Seam Grip over the interior seams will bring that factory-fresh warmth back. It’s the best way to extend the life of an aging suit.
Proper Application Techniques for Best Results
The secret to a successful repair is patience and precision. Always apply the adhesive to both sides of the tear if possible, and use a small brush or toothpick to ensure the glue reaches the very bottom of the cut. Avoid over-applying; a thin, even layer will bond much better than a thick, messy glob.
Use masking tape to create clean lines around your repair area, preventing the glue from spreading onto the surrounding neoprene. Once applied, hold the edges of the tear together firmly for a minute, then let it cure for at least 24 hours. Rushing the curing process is the most common reason repairs fail prematurely.
Extending the Lifespan of Your Wetsuit Gear
Beyond repairs, the best way to save your gear is by changing how you handle it. Never stand on your suit while changing, as the grit on the ground acts like sandpaper against the neoprene. Use a dedicated changing mat or a plastic tub to keep your suit off the asphalt.
Store your suit on a wide, padded hanger to prevent the shoulders from stretching out, and never store it in a damp, folded pile. By addressing small nicks immediately and practicing good storage habits, you can easily double the functional life of your gear. Take care of your suit, and it will keep you warm for seasons to come.
Maintaining your wetsuit isn’t just about saving money; it’s about staying comfortable and safe in the water for as long as possible. By keeping a small repair kit handy and addressing damage early, you ensure your gear is always ready for the next adventure. Treat your suit with respect, and it will continue to be your most reliable companion in the surf.
