Gunite Pool Freezing Temperatures: Protecting Your Plaster Finish

The freezing water temperature for a gunite pool is 32°F (0°C). At this temperature, the water will begin to freeze and expand, which can damage the plaster finish of the pool. For this reason, it is important to heat the pool water to at least 34°F (1°C) in the winter months to prevent damage.

Here are some tips for preventing plaster damage in gunite pools during freezing weather:

* Keep the pool water at least 34°F (1°C).

* Use a pool cover to help insulate the water and prevent heat loss.

* Drain the pool if you are going to be away for an extended period of time.

* If the pool does freeze, do not try to thaw it by pouring hot water into it. This could cause the plaster to crack. Instead, use a heat lamp to slowly and evenly thaw the ice.
