Easy repair for any tent seam emergencies.


Hi Gear Seam Sealer is a multi-purpose waterproof seam sealant for quick and easy repairs on tents, clothing, rucksacks, tarps, or any waterproof cotton, canvas, nylon or synthetic fabrics.

To use, just apply onto the inside of a cleaned seam that needs repair.

Useful for any waterproofing emergencies, and essential for any tents that aren't factory seam-sealed.
A handy item to take with you when you're camping, and great to have at home to patch up your gear, post-trip.

Dont waste your money!

It is inflexible and as soon as I flexed the newly sealed seams, they de-laminate.

I have to now remove all the sealant from the hammock undercover I just made.

Oh Joy!

Can't give much on lifespan of this product but, it does what it is meant to. I would suggest treating the seams of camping equipment regularly, maintaining them by cleaning and treating. This was great to have to hand when a couple of seam tapes split in our new tent in some small spots on first pitch, also handy to treat outer seams for extra piece of mind. Don;t forget to get a full treatment for materials which include a UV protection. This should be used as part of a full service for equipment as well as for little emergency repairs. If you need to do seams upside down even vertically, turn the bottle upside down, squeeze a little through the sponge tip and then apply liberally up to half an inch either side of the seam.
