Last spring we used the Aquafin 1K - 2K waterproofing solution on a replaster.  This spring the whole pool delaminated and all the plaster came off in sheets.  We contacted the manufacturer and sent samples to them asking for root cause analysis.  The samples were inconclusive and we were requested to provide core samples.  The Field Application Manager told us the reason for the failure of the bond was our application was not thick enough.  It would seem that it is not very forgiving; have any other builders had similar problems with the product?
