A gunite pool is a concrete pool where the water is added as the cement is applied. The gunite pool uses a rebar framework that is sprayed with a concrete and sand mixture. The sprayer unit combines a dry, gunite mixture of concrete and sand with water just before spraying. There are a variety of finishes including all-tile, pebble, granite, and colored plaster. Gunite pools are durable and can be built in any shape and size.

A gunite pool should be resurfaced proactively. If left too long, damages on the pool surface can lead to leaks and cracks in the pool structure. A cement/plaster pool will need to be resurfaced every 3-7 years. However, a fiberglass pool is far more durable and can last 15-30 years between resurfacing.

Gunite pools can be customized to complement your home and your backyard. The method of construction of a gunite pool creates little restriction on the size or shape of the pool and allows endless pool designs and variety of finishes. The surface of the new pool can be finished with tile, pebble, granite, colored plaster or glass. The endless possibilities for the designs of gunite pools make them a top choice for many home owners today.

The length of time it takes to complete installing a gunite pool can vary depending on the size of the pool. It takes approximately six to eight weeks to install a gunite pool. Constructing the pool takes 14-21 working days. This includes the time allowed for other sub-contractors involved (electricians, masons, landscapers, plumbers, etc.), to complete their work on the pool. Concrete requires approximately one week drying time. However, actual time taken may vary from case to case.

* Test the pool water with a swimming pool test kit for algae, mold or germs.
* While the pump is on, apply shock to the pool for about 8 hours.
* Apply algaecide to fight algae growth in the water.
* Set the pump to backwash the water so that it cleans the pump and the filter.
* Drain out water from the pool to about 6 inches below the skimmer.
* Using a shop vacblow out the water from the pool hoses.
* Cover the pool with a durable pool cover.

- Identify the location of the stain(s). They are usually found near the top edge or just a few inches below the water line.
- Drain water out of the pool to expose the stains.
