For whatever reason I’ve proved myself thoroughly inept at using rubber cement or wetsuit repair glue to actually fix wetsuits.
But, I’ve been having good results with good old Gorilla Glue. I weigh/clamp the parts as the glue foams and the next day I’m good to go.
For both applying neoprene patches over big holes and for plugging up pinholes.
I know it’s may not be big news, but hey, it’s keeping me warmer and it’s cheap and easy.
Are you sure?
the reason of why? wetsuit glue is that it is relatively
safe for most peoples skin to get in contact with it.
Gorilla glue doesnt sound like anything I want rubbing
against my skin. Additionally it would need properties
of being pliable or flexible. …Never used it!
Good question. I though that after 24 hrs Gorilla Glue is inert and safe.
Anyone know for sure?
when it’s thin, it is flexible enough to bend around my forearm or foot/toe area as I put the suit/booties on/off.
I doubt it would stretch as much as my shoulder panels do – their condition kinda decides when it’s time for a new suit
Gorilla glue doesnt sound like anything I want rubbing
against my skin.
GG is FDA approved for food contact. I doubt it will cause any reactions with your skin. I have a hole in the butt of one of my suits. Since I already have an open bottle of GG I may give this a try.

I dont know where you found that at?
as its not reflected in the MSDS.
However, the MSDS just may be for the unreacted/non-dry product.

Harmful by inhalation. Irritating to eyes, respiratory system and skin. May cause sensitization by inhalation and skin contact.
Inhalation If aerosol or vapour is inhaled in high concentrations: Move affected individual to fresh air
and keep him warm, let him rest. If there is difficulty in breathing; call a doctor.
Eye contact Flush eyes for at least 10 minutes while holding eyelids open. Contact a doctor.
Skin contact Remove contaminated clothes immediately, and wash skin with a cleanser based on
polyethylene glycol or with plenty of warm water and soap. Consult a doctor in the event
of a skin reaction.
Ingestion Product is not intended to be ingested or eaten. If this product is ingested, severe
irritation of the gastrointestinal tract may occur, and should be treated symptomatically.
Do not induce the patient or animal to vomit. Call a doctor, ambulance or seek
veterinarian assistance immediately.
Upper flammable limit (UFL): Not determined
Lower flammable limit (LFL): Not determined
NFPA: Health – 3, Flammability – 1, Reactivity – 1
HMIS: Health – 3, Flammability – 1, Reactivity – 1
General fire hazards
Down-wind personnel must be evacuated. Do not reseal contaminated containers; a chemical reaction generating carbon
dioxide gas pressure may occur resulting in rupture of the container. Dense smoke is emitted when product is burned
without sufficient oxygen. When using water spray, boil-over may occur when product temperature reaches the boiling
point of water, and the reaction forming carbon dioxide will accelerate. MDI vapour and other gases may be generated by
thermal decomposition.
Page 1 of 4
Special hazards in fire
In case of fire, formation of carbon monoxide, carbon dioxide, nitrogen oxide,
isocyanate vapour, and traces of hydrogen cyanide is possible.
Extinguishing Media
Carbon dioxide, dry powder, and foam. In cases of large scale fires, alcohol-resistant foams are preferred. If water is used, it
should be used in very large quantities. The reaction between water and isocyanate may be vigorous.
Required special protective equipment for fire-fighters
Fire fighters should wear full-face, self-contained breathing apparatus and impervious protective clothing. Fire fighters
should avoid inhaling any combustion products.
Personal precautions
Wear full-protective clothing and respiratory protection as required maintaining exposures during clean-up below the
applicable exposure limits.
Environmental precautions
Do not discharge spillage into drains.
Clean-up procedures
Remove mechanically; cover remainders with wet absorbent material (e. g. sand, earth, sawdust). After approx. one hour
transfer to waste container and do not seal (evolution of CO2). Keep damp in a safe ventilated area for several days.
Handling
Avoid contact with skin and eye. Do not smoke, eat and drink at the work-place.
Ventilation: If vapour or mist is generated during processing or use, local exhaust ventilation should be provided to
maintain exposures below the applicable limits.
Personal protection: see Section 8.
Storage
Keep product away from sources of alcohols, amines, or other materials that react with isocyanates.Avoid prolonged heating
above 160°C/320°F. Store the product in tightly closed containers in a well-ventilated place and in accordance with national
regulations. Keep out of reach of children.
For exposure controls see Section 15.

particulate filter is recommended.
Eyes protection Chemical goggles or full face shields are recommended. An eyewash fountain
and safety shower should be available in the work area. Contact lenses should
not be worn when working with this product.

Safety Data Sheet for New Stronger-Faster Gorilla Glue
Page 4 of 4
Ive used gorilla glue on my suits, booties, board once and even on a cut when I have no super glue once. It works well with suit and yes on a bigger area it does not hold up to well, but for simple small cuts and pin holes it works really well. If you want to try something else use a patch kit for a bicycle tube repair kit. Wicked durable and will last alittle longer, has worked for me.
Late
Soul
I use solvent based Contact Adhesive. Just make sure it is really dry before connecting the surfaces to be stuck!
I’ve used Superglue with good results for minor repairs. The only problem is, the glue holds, but the adjacent rubber will start to tear because you’ve created a hard spot in the material. I only use it when something’s on the way out. It’s perfect for those holes you get between your fingers in your gloves… when you’re at the end of the season, trying to squeeze a couple more months out of them.
for busted seams there is a kind of nylon tape with acrylate based adhesive, clean the repair area well and clamp… the tape will eventually fail but you can just re-do every ten surf sessions or so…
For small holes and tears there is a bicycle innertube repair strip type tape which also works super well, I think the adhesive is like solvent based rubber cement… which brings the next tip, old inner tube rubber, cleaned, slighly scuffed with 60 grit and clamped with rubber cement…
I recently used Shoe Goo to fix a torn hood (chin strap was just about completely separated, only the nylon covering was holding it together, which made the strap 1/2 inch too long). The repair is very durable and the strap is now the right length (so the hood doesn’t leak) but it’s not very flexible… Not perfect but at least I didn’t have to buy a new hood.
I have also used the same product to fix booties, which of course is more in line with its intended use.
I use Sikaflex marine sealant. Super sticky and being a rubber is really flexible.
I guess 3m does lots of similar stuff.
I’ve tried lots of stuff over the years… in the end, nothing better than good newish neopren cement. esp. on the “new” super flex rubber… everthing else gets stiff over time… Just my deal.
