Most repair kits come with a double sided adhesive tape that goes around the perimeter, or you could heat it up again and use the old adhesive. Can't attest to the waterproof factor.
It's a really difficult and risky repair unless you have specialized tools. You can use a hot plate to separate the lcd from the glass and work it apart with a playing card, then use a special uv adhesive to attach the new one . Most skilled technicians and repair shops won't attempt this repair because of how fragile the lcd is. They make machines that automatically separate the lcd from the glass but it's still a risky repair. I wouldn't recommend trying it unless you want to do it as a learning experience. You'll most likely have to replace the entire screen.
