The kit contains:- 2 large patches of reinforced PVC cloth- Glue- Valve wrenchUse the glue and PVC patches to repair cuts and punctures in your inflatable board.A known problem: when you are inflating your board, air seems to be leaking out and when you reach approx. 10 PSI, the valve won’t close automatically. That means that the valve is not mounted tightly into the board. Solution: Take off the valve cap and place the wrench onto the valve. Turn the wrench clockwise until it becomes hard to turn. The valve is now mounted properly and you can inflate your board without any problems.
