White marble plaster is the standard for pool plasters. As the oldest and most common type of plaster, it's probably the one you're most familiar with. Made from cement, white marble aggregate, and water, it's decently sturdy while remaining flexible and lasts between 9 and 12 years on average.

Plaster, if applied properly, lasts 10 years and costs $4 per square foot, while pebbles—one of the most durable aggregate options—have a lifespan of 20+ years and a cost of $10 per square foot.

The lifespan of pool plaster depends on many factors, such as the quality of the plaster, the water chemistry, and the maintenance practices. On average, a well-maintained pool plaster can last between 7 to 12 years. However, some swimming pool owners have reported that their plaster lasted for more than 12 years.

Pool resurfacing or replastering should be done every 10 years. This is based on the surface lifespans of cement and pool plaster material. But constant use, chemical exposure, and climate changes can damage the pool plaster. That said, you should consider resurfacing your pool every 3 to 7 years.
