Perfect for repairing the minor hole or slits in your liners or inflatables. Comes complete with adhesive, applicator and a length of patch. Simply apply the glue around the damaged area on the inside of the pool and once tacky you press firmly the patch onto it and hold it there for a couple of minutes. You must always make sure that you do the patch on the inside of the pool so that the pressure of the water is pushing the patch onto the liner and not coming through the hole before it then starts trying to push the patch off.
