The color of this pool plaster is grey. The water, sky reflectivity then result in the blue color, enhanced by the dark blue tile at the water's edge. There are many ways to achieve this effect, but it is most successful with the cement plaster of the pool shell. The plaster method we utilized on this pool is termed "hydrazo", a method that minimizes "mottling" of the plaster over a period of years.

I wish the brick, pool tile, pool plaster and pergola were flagged....

is there a white wash on the brick or sealant?
