an elementary level, a pool is to hold water for our enjoyment.
There are many surfaces that will provide a water tight surface
creating a pool. Surfaces such as plastic, vinyl and fiberglass
are popular in portable pool products. In ground pools are
primarily made out of concrete shells. The final surfacing
of the concrete shells is often either plaster or aggregate.

Plaster is what is used to finish the interior
surface of the pool. It is used because the foundation material
of the pool, typically gunite or shotcrete, is too porous
to hold water.
The plaster is watertight, and in an ideal environment will
last twenty years. However, unless you can figure out how
to keep your chemical levels at the ideal levels constantly,
you can expect that you will need to have your pool replastered
about every fifteen years or so. Recent advancements have
incorporated color granuals to enhance the color of the pool.
Aggregate type finishes have been growing
in popularity over the past 5-10 years. The most popular brand
is Pebble Tec. The aggregate type
finish adds color depth to the pool through a blend of naturally
colored pebbles mixed in with the plaster. The result is a
durable surface that resists staining and provides more design
options. With a wide variety of colors available, your options
are limitless when creating an ambience at your backyard pool.
