With the gunite process complete and the cement having cured, the final steps can begin. The pool has taken on shape and form and has become more than just a hole in the ground.
The first process after gunite is to remove all forming materials. Removal of these materials is necessary to access the pool shell exterior and correct any areas, which may need parging or waterproofing.
Tile: A band of tile is now placed at the pool's water line. Thin ceramic or slate tile provides a durable and readily maintainable surface at the water line. The standard tile is a 6" x 6" square made of slate or frost free ceramics. Choosing a color must involve consideration of the interior finish, coping and decking materials.
Coping: Coping is the term used to identify the stone or concrete material used to cap the pool shell wall. A common form of material used for this function is Bluestone flagging, but many other options are available including pre-cast cement material. Natural stone coping offers the warmth, texture and sturdiness of stone. Materials ranging from quarried granite, limestone and bluestone to natural fieldstone offer beautiful and long lasting coping solutions. In working with natural stone, it is very important to specify consistent coping thickness for this most visible pool element.
Marcite or other interior finishes: The interior finish of a pool can range from waterproof paint to fiberglass/acrylic linings to tile and Marcite. Due to cost and maintenance considerations, SCOTT® recommends Marcite, a marble aggregate plaster-like finish troweled on the pool interior. Marcite can be tinted a variety of colors from black to white. The surface is affected by a variety of cosmetic imperfections such as trowel marks, small shrinkage cracks and mottling are considered normal for this application. Marcite is a long lasting and beautiful natural finish in a properly maintained pool. Paint is a uniform finish available in a wide variety of pigments. However, it is maintenance intensive, requiring frequent pump-downs, sandblasting and re-painting. Tiled interiors, although expensive offer the chance of beautiful mosaics or designs inside the pool. A product known as pebbletech or pebblecrete involves a small stone aggregate, much like exposed aggregate covering the interior of a pool.
