By the nature of the pool industry the applicator will work out his profit factor so the option is to pick the base product that returns the best profit which is of course Marble to this add White Portland Cement, and to add a little lift to the finish throw in some Colored Quartz and yes it looks great, even better than it was.
You may even believe you have a Quartz Plaster, really you are being fooled. A good test to find out how good your plaster is is take a small amount put it in a glass and add some acid to it leave it for a couple of hours and see if any remains, you will find the marble acts like a creaming soda and disappears.
Now that is why Marble Based Pool Plaster is outdated and what the industry should be aiming for is a 100% Quartz based Plaster which means the only thing that can deteriorate over time is the Cement which means that who knows 10, 15, maybe 30 years from a pure Quartz Plaster is a possibility.
For 15 years I have been trying different products in an attempt to come up with a good plaster for Swimming Pools here in New Zealand and have found that almost any color that wont fade is possible.
What makes Quartz better is the fact it is very hard and inert where Marble is Porous and stains. This means that pool water treatment is more forgiving.
To sum up the industry likes the old and tried products and as yet the Plaster I have developed is awaiting a Distributor in the USA.
Another discovery i have made with Quartz is as a Filter Media, it is far better that Glass Sand or even Zeolite filtering down to 3 microns it even removes Iron (from rusty water pipes)
