Plaster Types
Grey or white- These surfaces are the least expensive, but they have the shortest life and require
the highest maintenance. Basically, they are protland cement, with or without a tint additive. For
longer life stone, glass accents and other durable items have raised the life of the finish and widely
expanded the color choice.
Pebble Tec® (Small stones in plaster)- The developer of the imitated small stone in the plaster has
been Pebble Tec®, offering a multi color, more water resistant finish. 3M Diamond Brite and other
stone finishes have become popular.
Operating Issues
1) These pools must never allow calcium hardness to fall below 200 ppm.
2) These pools must be brushed weekly in high season or employ a suction vacuum.
3) These pools will stain or bleach, require 7 to 10 year reapplication of the finish, and are the most
amicable to attached custom water features.
4) These are the only pools which allow large, free form designs and multiple water features attached
with one filtration and purification system.
Because they lend themselves to free form design, plaster pools will always be a dominant force in
the swimming pool industry. In other markets, they are significantly more expensive to construct.

Plaster Pools
These pools are also referred to as
plaster, granite, concrete, pebbletech,
marble light, marcite, or diamondbrite
pools. The dominant form of pool, par-
ticularly in the southern US and Europe
is a rebar reinforced, plaster or concrete
based shell and a top finish. The terms
granite, pebbletech, marble light, and dia-
mondbrite apply to the finish. Absent one of
these finishes, ceramic tile or glass pools could
be cared for in the same manner. Resurfacing
these pools with fiberglass finish has been a growing
trend over the last 20 years.
