Hi all. Here's the story. Pool was completed late summer of 2005 by Anthony Sylvan. Surface is Pebble Tec. At the time the installer had a company handling openings for them. The company opened the pool, ran the filter and told me to do nothing but brush the surface until they come back. Well - it turned out the noobs they sent out did not open the main drain. You can probably imagine what happened ... and you'd be right. I was essentially brushing cement dust (or whatever) which built up in the main drain and solidified. Eventually the installer had to send a diver out to diagnose and to see if they could clear it. The blockage was so deep and solid that they were unable to do so. They had to drain the pool, jackhammer out the drain, replace it and then resurface that area. It looked slightly off from the rest. They told me this would go away over time and I, like a dolt, believed them.
It hasn't and I am now sick of the area looking like a large stain around the drain. In addition - I have a couple of other areas that appear slightly stained (I had some issues with low alk and low calcium due to prolonged and heavy rain). I also have some tiles just below the coping under the stone waterfall that come off each year. Started out as a couple of tiles. This year we were up to about 9 or 10 with a few others coming off further down the pool.
I was thinking I may need a resurface, taking care of the tile along the way. Is this the right approach and are there any considerations I need to take under advisement? What is the prep like on a resurface of Pebble Tec?
