A thermoplastic polymer powder coat such as ecoFINISH will protect and seal fiberglass. Covering a small to moderate-sized pool typically costs between $10,000 and $14,000. Although it's a more expensive option, this type of finish is also very resistant to weather changes, harsh chemicals, extreme temperature changes, and other factors.
Diamond Brite, a name brand, can cost approximately $5,000 per project. Pebble Tec and PebbleSheen brands can cost $9,000 to $13,000 to install. These high-quality aggregates can last many years without any maintenance and are covered by many top brands.
Tiles are made mostly of porcelain, stone, and glass. You can even mix different types of tiles in your pool.
