Pool Replaster Time

Here we have what used to be a beautiful pool.  Apparently pools need to be replastered every 10 years.  We bought the house from people who renovated the house.  They painted the pool with cheap pool plaster paint that covered up the damage...two years later it showed...five years later we are paying the price for our ignorance.  Premier Pools out of Sacramento comes out tomorrow to start the process of the replastering.  They have to come in with jackhammers and re-cement in order for new plaster to adhere...stress!
