For further information on crack isolation, go to the Noble Company website at: http://www.noblecompany.com.

Look up NobleSeal CIS and NobleSeal TS. The first product is for crack isolation only and uses an adhesive to attach to the floor substrate. The second product additionally provides waterproofing and is applied with Latex-modified thinset. It is also suitable for use on vertical surfaces, such as shower stall walls or steam rooms. Both products are made from durable and proven Chlorinated Polyethylene (CPE).

You only need to provide the isolation membrane over the cracked area (spanning the crack by about 1-2 feet on each side). Although, putting it on the whole area is OK too, and will help to mitigate future cracking.
