Fellow TFPers –
I had my pool professionally replastered on 12/29/10. The pool had a lagoon (gray) finish and we chose to keep it that color. As the pictures show, there are whitish streaks running down the sides of the pool toward the drain, as well as some whitish mottling around the steps. While refinishing, the pool company said I would see a whitish “alkaline†coming from the plaster, especially on a dark finish, and that brushing and proper chemistry would take care of it. Almost 2 weeks out, I haven’t seen much improvement. BTW - The color variation in the lagoon finish is good with me – as long as it’s normal variation and not scaling or stain.
But before that, here’s a little more info:
The day they did the replaster it was around 50+ degrees (Tulsa, OK), completely overcast with really high humidity. They started spraying the plaster around 10a and didn’t leave until about 8:30p because it wasn’t setting up very quickly. But they got it all smoothed out but didn’t want to start the fill until the next morning. The hose/rag etc. was placed in the pool and I was to turn on the water first thing then the next morning, which was about 11 hours after they left. That morning these streak were there, starting at the tile line and ending at the drain. I assume it was the “alkaline†they were talking about.
Once the pool was filled, I started the pump and tested the water. Here are the original results:
Water temp = 48F
FC, CC, TC = 0
TA = 120
PH = 8.1
CH = 150
CYA = N/A
Sort of following the recommendations of the National Plasterers Council’s Pool Start-Up Procedures, I adjusted used muriatic acid to lower the PH and TA levels. I also added a sequestering agent. After a couple days of testing and brushing twice a day, I first got the pool to around:
Water temp = 42F
FC, CC, TC = 0
TA = 100
PH = 7.5
CH = 150
CYA = N/A
After a week I was some improvement around the tile line, but the streaks remain very prominent. Making some progress, I continued with the NPC info and adjusted the CH to 200. After some more reading, I came to the conclusion (right or wrong) that the streaks are scale and a lowering the TA & PH even more would get rid of them – so I added more acid. I retested yesterday and had this:
Water temp = 38F
FC, CC, TC = 0
TA = 100
PH = 7.5
CH = 150
CYA = N/A
So I would appreciate your comments on what’s happening here. Are the streaks scale? If so, what’s the best way to handle the situation? If not, OMG WUT DO I DO?[attachment=2:39zpd5v4]pool.jpg[/attachment:39zpd5v4][attachment=1:39zpd5v4]pool1.jpg[/attachment:39zpd5v4][attachment=0:39zpd5v4]pool2.jpg[/attachment:39zpd5v4]
Thanks!!
