Plaster finishes are more expensive than paint but offer excellent protection and a classic design for your pool. Most pool plaster consists of cement, water, sand and water. Other mixes contain marble aggregate. The cost to refinish a small-sized pool with plaster is around $7,000-$10,000. But, you need to keep the coating clean.
There are three types available: those with vinyl liners; those made from fiberglass; and those made out of concrete.
Pebble-plaster aggregates, such as Pebble Tec, or Pebble Sheen, are the most expensive but create a striking look and a smooth, river-rock-like texture underneathfoot. Pebble blends are among the most resistant to chemical and staining of all plaster techniques.
