Marcite is a "plaster" made from marble dust and white cement. It's put on top of the gunite and gives the pool a smooth finish and bright luster.
Marcite is a thing of the past, at least here in Florida. It used to be a good product, but after the removal of asbestos, it does not last as long as before. The quaztz aggregate finish replaced marcite. Instead of use of marble,like in marcite, it uses quartz. Diamond Brite is one of many brands available. Then you have hydrazzo which is a kind of marcite with a twist; it is polished after finished to a glassy feeling. Pebble finish is also available; it is a little bit rougher than quartz aggregate finish. The latest thing for pool finish is the use of glass beads(beadcrete).

I live in Southern California and my pool cost around $7,000.00 to re-plaster and re-tile. I have a large pool with attached spa. I also had some plumbimg repairs (new Jandy valves, new return lines) which were included in this price. They also replaced the side steps (in the deep end), as these don't survive the demolition. This was in summer, 2003.
