I've worked with vinyl liner pools for a long time, only dealing with concrete/plaster pools in a limited capacity. Recently, I've been finding myself a bit more involved with new concrete/plaster pools, and I'm trying to learn what I can to make sure these pools are being treated right. In the past two seasons, I've picked up three new plaster finished pools. The finish varies between the three in terms of uniformity. So I'm wondering why. What causes the blotchy appearance on a plaster pool? Is it just the nature of a plaster pool? I've talked to some other pool pros that deal with plaster pools, and they have said that if the pool wasn't brushed well during the first few weeks, there will be calcium build up. Of the three pools I deal with, one was brushed by a caretaker, another by the customer, and another by pool guys. None of them have an even uniform color.
I was just hired to brush down a pool that was refinished, and I want to make sure that I am doing whatever I can to make the finish look right. My plan is to brush daily for the first week, then 3 times a week for the next three.
I did the first brush down today, and I didn't see any difference in the appearance after brushing an area. I didn't see any cloudiness coming off the bottom as the brush passed over it. I was kind of expecting to see something. I'm already seeing some blotches in this pool, and it was only filled yesterday. The chemistry was pretty good. TA was a little bit high, otherwise it looked good.
I'd appreciate any guidance you guys can offer.
