My alpkit 3/4 mat has developed 2 punctures, both right on the inside edge of the seam. Ones on the corner of the valve too to make it even more awkward.
Is there a way to repair them when they leak there, no way a patch will glue into the fold. Some sort of viscous glue/sealent that I could inject through the hole (would need a needle) and let it bubble out till it seals?
Superglue. Smear it on, then spend half an hour picking it off your fingers.
(This is what I was advised to do on mine by Alpkit themselves when my Fat Airic went in much the same way.)
Try tent seam repair. It is a thick glue that cures to be rubber like so will stay in place.
I'll give superglue a go, can always wash it off with nail polish remover if it doesnt work.
Acetone/nail polish remover, it just washes it off!spend half an hour picking it off your fingers.
Yeah, but where's the fun in that?
Superglue. I have repaired two blow up beds by just smearing superglue over the splits on seams and then holding it in place for a while. Then more superglue.
no specific experience but maybe try some sugru? I am very pleased with the results I have achieved with other items. There's a technical data pdf on their website that may in this case help determine suitability.
