I need to pour a 4" slab of decking around a pool and match it to the
existing one with cool-crete (or cool-deck...is there a difference?)

Is cool-crete (cool-deck) a product one can buy, or is it a specific mix of
cement, sand and other ingredients?

The existing slab has a knock-down texture which I plan to match by spraying
cool-deck material from a sheetrock texture sprayer if it will flow, or by
splashing the material from a stiff broom. Any suggestions are appreciated.

Thanks
