Background
Our pool needed to be resurfaced so we found a company to do this for us. The contractor asked us what color we wanted the surface to be, and I said I wanted it to be the same color that we had. In a later conversation, he mentioned we would be getting the regular "white" color. I had to correct him that our pool was a light blue, not white. He then had to correct me and I learned that our pool is indeed white. Light refraction just makes it appear light blue.
I had also never known there were color options, so we decided to explore what some other options might be and he took us to visit a few non-white pools. It is very interesting how the color and the surface and the color it appears are very disconnected. They all give you some shade of blue. If you get a dark gray surface, it will look like a very nice deep Caribbean blue. A green surface looks more like a lagoon or pond. And if you get a blue surface, you get some seriously deep blues, tending to black in deeper water.
In the end, we stayed with the white color. If we get algae growing in the pool, I'd like to see it and those other colors can mask that.
Grinding and Chipping
This is a messy job or removing the old surface and chipping aware at all the inlet, drains, etc.
