Seam Grip WP Waterproof Sealant and Adhesive for Jackets, Tents, Sleeping Pads and Outdoor Fabric | Repairs Rips, Seals Seams on Nylon, Canvas and Vinyl

Amazing stuff. Works as a thick sealer and also as a cement.

I recently had to deal with some bad seams on a tent I bought, and this sealant came to the rescue. What I really liked about this product was how easy it was to apply. It went on smoothly, and the drying time was impressively quick. Within a short period, the seams were sealed, and the tent was ready for use again. One thing to keep in mind, though, is that while the application process is simple, you need to be careful to avoid any mess, as it can get quite sticky. Additionally, depending on the size of your project, you might need more than one tube to cover all the problematic areas. Despite these minor issues, I’m pretty sure this sealant will outlast the tent itself. The seams feel much sturdier now, and I have no worries about them giving out in the middle of a camping trip. If you’re facing similar issues with your outdoor gear, this product is a reliable and efficient answer.

It's somewhat hard to know what the difference between all the Gear Aid/McNett sealing products really is. This material is extremely heavy duty and effective, but somewhat tricky to apply neatly. It has the consistency (and smell) of model glue or a thick general-purpose adhesive, but it really flows out nicely and grips seams and fabric well. The end result is a flexible, tough, glossy, somewhat thick, somewhat tacky, 100% waterproof seam. My advice for applying it would be to forget the brush-cap thing and go out and buy a few more bristle brushes. They don't have to be 'acid brushes' like the one supplied, but they should be somewhat soft and no wider than 3/8" – cheap artist brushes should work fine. You want several and you want them cheap because they will be ruined after using them with this stuff. When applying, I would squeeze out less than you think you need. Although it's thick, it can be brushed a fair amount and it will still flow out nicely. I found that if I brushed it out as thinly as I could while still getting a complete coating, the final result was good. If you put too much down, the end result is too bulky and thick, which can be a problem if you're folding it, etc. So keep it thin! You can always squeeze a small amount on your brush and add to what you've put down, but you won't be able subtract from what you've put down very easily. So this is very effective stuff, but it's not very pretty. And it's tacky after it has dried – I ended up applying seam tape over it to help take away the tackiness... it was more effort and cost, but the results are truly bombproof, durable and look reasonably good.

This stuff is GREAT!! Bought it to replace a vinyl window on my trusty old REI tent rainfly, it did NOT disappoint! I removed the old cracked vinyl, cleaned the area with rubbing alcohol, and trimmed the AWESOME iridescent orange vinyl (that i bought separately) to fit. I made the mistake of applying this on a 90° day so the glue was pretty runny, and it led to some overflow onto the window side. Not visually as appealing, but it is definitely not going to leak! I plan to go back over the rain fly seams for spot repair in other areas as needed. This is a fantastic product!! Store your leftovers in the freezer to keep them from drying out.

My tent windows had delaminated and I needed way to glue them back into the tent. This product did a fantastic job of adhering, was very affordable and sealed up those windows nicely. I found a great video online with instructions and this product delivered for me. It was so easy to use and dried quite quickly. I will buy again if any of my other tents needs a repair!

I had a few uses for this product so I purchased the big 8oz unit. I treated all the seams on my tent and my hiking boots with this product as well as some rain pants I use when riding my motorcycle. The good: It works very well. I squeeze a golf ball size blob of it into a small yogurt cup and use one of those small metal handle paint brushes to apply it to the material I want to seal. This works well as the seamgrip product dries slowly allowing me to work for an hour or more at a time. The not so good: Seamgrip dries very slowly, requiring that the tent (if you're sealing tent seams) must remain setup overnight, and preferably 24 hours or longer, to allow the product to fully cure. There is an accelerant (Cotol-240) which will speed this up greatly. However the Cotol-240 is not easy to work with and it is fairly expensive when you consider the small amount you get. The second issue with seamgrip is that it dries very shinny, so if you put it on your rain gear you'll see the seams from a mile away. Well, rain gear isn't supposed to be a fashion statement anyway. If you can get to the inside of clothing seams that would be the better place to apply the seamgrip and you won't have the fashion issue to deal with. Conclusion: Buy the big tube if you have lots of waterproofing to do or if you know you'll use it often, like at least once every month. The reason for this is that seamgrip will harden in the tube's opening, making it difficult or impossible to use a second time if you wait too long and allow too much of the product to harden in the tube. I've only used seamgrip recently so I can't vouch for its long term effectiveness, however, in the short term the product remains flexible and remains attached to material when folded up and opened up many times.

Worked excellent for a tiny tearnin a downfilled jacket

Muy buena calidad y duradero

Excellent product for seam sealing and patching. I primarily bought this to apply a patch to a significant patch for my nylon tent and after 24 hours it made a good solid bond which dried perfectly clear whle remaining flexible. I had some stitching to support the tear and used this to seal the stitching afterwards. I personally tried thinning it with white spirit to pentrate the stitching better but still found it very thick though it worked well. I found it a bit sticky for seam sealing though it was very effective. Bonding and grip was excellent. Tubes just a bit small for a major repair (hopefully a rare event for any camper) and quite expensive - I would have liked to be able to but a larger tube size despite cost. Primary lesson is not to rip my tent so badly next time! Excellent for restoring the seams in a worn out old tent.

Nachdem meine sich selbst aufblasende Isomatte am Ventil undicht geworden ist, wurde in einem Blog auf das McNett Seamgrip hingewiesen, womit man den Fehler angeblich leicht reparieren kann. Und ja, ich kann das absolut bestätigen. Aber nun mehr zum Produkt: Seamgrip ist ein selbsthärtender Kleber auf Polyurethan-Basis, welcher Risse, Löcher oder undichte Nähte einfach abdichten kann. Die Dämpfe sind laut Produktbeschreibung nicht unbedenklich, daher sollte man an einem gelüfteten Ort arbeiten. Der Kleber riecht für mich aber nicht Kleber-untypisch sondern so ähnlich wie Pattex. Mit der Tube wird ein Einmalhandschuh und ein aufschraubbarer Bürstenkopf mitgeliefert. Ob der Bürstenkopf nach einmaliger Anwendung noch vernünftig gereinigt werden kann, weiß ich nicht. Ich habe ihn eh nicht gebraucht. Zunächst soll die zu behandelnde Stelle z.B. mit Isopropanol entfettet werden - das habe ich mir in meinem Fall gespart.Danach wird der Kleber darauf verteilt und kann mit dem Finger mit Handschuh verstrichen werden. Der Kleber hat wirklich Pattex-Konsistenz, daher stelle ich es mir eher schwierig vor bei dem abdichten von Nähten eine schön dünne, gleichmässige Schicht zu bekommen. In meinem Fall hab ich eine 1-2 mm dicke Schicht aufgebracht und habe die Isomatte über Nacht trocknen lassen. Trockenzeit sind 8-12 Stunden, aber ich würde eher einen ganzen Tag warten. Danach war die Stelle absolut dicht und der getrocknete Kleber verbleibt gummiartig flexibel. Für den Fall (z.B. bei Nähten), dass später Kleberfläche auf Kleberfläche gefaltet werden könnte, empfiehlt der Hersteller die Oberfläche nach dem Trocknen mit ein wenig Talkumpuder zu bestreuen, weil die Kleberoberflächen sonst aneinander haften würden. Top Produkt für Reparaturen im Camping/Outdoorbereich. Wobei man natürlich die 12 Stunden Trockenzeit berücksichtigen muss.

lo utilizzo per sigillare-isolare-irrobustire tessuti e materiali vari stramati o per incollare quelli neoprenici delle mute da sub. l'ncollaggio di due lembi non è immediato ma le parti vanno posizionate e tenute unite anche con del nastro adesivo o con delle pinzette apposite, tipo molletta da bucato. Ma è utile anche per cavi sfilacciati e molteplici altre cose. La sua consistenza fluida richiede una grande manualità nell'applicazione per il fatto che il collante essendo molto fluido va lavorato in un piano orizzontale per evitare colature dello stesso prima dell'avvenuta solidificazione che avviene dopo diverse ore. Quando solidifica è elastico, trasparente e impermeabibe e rende i tessuti tecnici anti-strappo. Ma va saputo utilizzare, Se cercate un collante rapido/instantaneo non fa al caso vostro-
