Well, I'm up to 3 layers on my garden hose now and still have some
leakage.  I re-read the package about the bonding time and it said to
not try to reposition after 2 minutes and it reaches full strength in
24 hours at room temp.  On the 3rd layer I only waited a couple hours
before testing it.  Each application I did1/2 overlapping as I wound
around, and I reversed direction with each layer.  The water is
definitely squeezing out between the layers like David says below.
