Some pool surfaces such as Marblesheen and Quartzon require a curing time of about 5 weeks during which time the chemistry must be closely managed according to the supplier's directions. At the end of that time, the pool can be handed over to Pooled Energy for on-going management. 

Please note that this type of pool can still remain highly chemically active for some years after installation of the surface, and that Pooled Energy accepts no liability and offers no warranty for the life and performance of any pool surface during or after the curing period. Those warranties are the responsibility of the suppliers of those surfaces.
