Pebble
The use of small evenly colored pebble set in white or gray cement has become a very much used system in the last 10 years. Its predominance has been brought about by the want for the "Natural Look" pool. The use of pebble is much less costly but the upkeep is greater because of its uneven textured surface.

Marblesheen - Marcite
A Mixture of marble dust & white cement, the system has been used for many years to provide a long term medium cost attractive finish to hundreds of thousands of pools around the world. It has lost fashion over the last five years due to the lower cost of the pebble finish, however I believe it is far superior to pebble finish. It does tale more of a tradesman to apply the Marblesheen than it does the pebble. The finish is a beautiful pristine white which gives bright blue looking water.

Plaster & Paint
Plastering- Renewing the interior surface of a pool to a beautiful smooth finish & then applying a number of coats of either, Epoxy of Chlorinated Rubber Paint , has been the choice of thousands of pool owners. The system is very efficient but does not last as long as Marble sheen or Pebbling. The repaint will need to be done each 4-5 years. Paint can be used to give some brilliant effects in pools using many different colors.

Fiberglass as an Internal Finish
Many pools are first plastered- Rendered & the four or five layers of fiberglass mat of varying thickness are laid over the plaster to give a smooth impervious finish. The Fiberglass can be colored to many beautiful shades. A bit cheaper than tiling but about the same life expectancy.

Vinyl as an Internal Finish
There are thousands of pools each year built with Vinyl as the final waterproof finish inside. In many cases of areas of bad earth movement & freezing of the water, The manufacturers claim that the Vinyl stands up better over a long period of time. The Vinyl comes in many colors & is quite cost effective. It can be used as a finish on a concrete constructed pool or on a specially built frame of metal or timber.

Vinyl-lined and fiberglass pools need no interior finish. All others must be plastered, painted, fiberglassed, tiled or coated in an exposed aggregate such as pebble or quartz. All interior surfaces have advantages and disadvantages, so you should discuss the options with your pool contractor before you decide.
