What is marcite?

Marcite is a white cement plaster applied to pool shells to create a finished surface. Unlike bare concrete or gunite, marcite gives pools their classic smooth, finished appearance and seals the underlying structure against water penetration and chlorine damage.

The material typically lasts 5 to 7 years before showing wear, staining, or requiring resurfacing. Its lifespan varies based on water chemistry, usage, and climate conditions. In the Naples area, sun exposure and seasonal water demand can affect how quickly marcite ages.

Marcite differs notably from aggregate finishes like pebble or quartz, which embed stones or aggregate into the plaster surface. While aggregate finishes are more textured and often more durable, marcite offers a cleaner, whiter aesthetic at a lower cost and with easier maintenance. Marcite pools also feel smoother underfoot and require less scrubbing to maintain their appearance.

When marcite begins to crack, stain, or lose its finish, pool contractors typically recommend resurfacing rather than repair. This is a common service among pool remodeling and renovation specialists in the region. Choosing marcite remains popular for owners seeking a traditional pool look and straightforward maintenance routine.
