Combination aggregate finishes are stronger and just as smooth if applied correctly. 1 part white cement and 2 parts marble dust is generaly a good marcite finish.On exposed aggregate finishes such as "diamond brite" exposing it by acid washing takes 2 years off of the lifespan. Wait until it needs washing and then do it.
If it is applied correctly it can be smooth. Very seldom that this happens. Any pool finish that has larger aggregate in it is always stronger. This is the same for any masonry by-product. The larger the aggregate the better and stronger it becomes. As pebbletec wears the rougher the surface may become due to the size of the aggregate.
The finish plaster is normally white all the way through. It sounds like you are dealing with a pool that has been replastered by the method of putting a "brown coat"/"scratch coat" (the gray plaster you noted) over the original finish plaster surface, and a new finish coat of white plaster on top of that. The scratch coat more like a thin concrete than plaster (doesn't have the white marble dust in it) and is used to get a better bond to the old surface.
