How to effectively fix a leak in an inflatable mattress that is leaking on a seam?

Question

It's not uncommon for air mattresses to leak along a seam. When this happens, repair kits are pretty much useless.

What is an effective way to repair a leak in an air mattress when the leak is along a seam?

If curing is involved, the curing will ideally take no more than a couple hours.

Also, ideally, the mattress would not need to be deflated for the repair to proceed. But that's just an ideal preference, and not a requirement for this QA.

I would try to use low viscosity glue. In Germany we have "Schweisskleber" which translates to welding glue. But it has nothing to do with welding. It's just a low viscosity glue. It comes in these cans

Deflate the mattress and use a brush to generously apply the glue along the seam. Let it dry and repeat. Do at least 2 layers, recommend 3.

There are different types of this glue for different materials.

Thanks Rubus. How long does that glue usually take to dry per layer? – End Anti-Semitic Hate Oct 07 '21 at 23:43
If I remember correctly about 24h..But I guess there are differences – CuriousIndeed Oct 08 '21 at 05:28
Thanks. The amount of time required is not ideal for repairing a mattress, but I still sincerely appreciate your answer. Your answer also uses a key phrase I hadn't considered: "low viscosity"... thanks for mentioning it. – End Anti-Semitic Hate Oct 08 '21 at 06:19
