A: The gunite shell must be maintained moist for at least 7 days after application is completed. The gunite should be sprayed with water using your water hose and spray nozzle. Gunite will cure better and properly if kept moist. You can apply a light mist of water hours after the gunite application is completed.
If not you will be fine especially since it rained one day. You can start watering now and you shell will be just fine.
Maintaining Your Gunite Shell
Not enough watering throughout the day will leave a negative impact on your pool's shell. It is recommended you water 3-5 times daily for about a week. Your concrete pool will thank you!
Water is applied to aid in hydration/curing, a process which decays exponentially, so watering is most critical in the first hours/days after placement. Concrete will continue to cure/harden forever, but the strength used for design work is the strength after curing for 28 days.
Hold the spray in one place until you can notice that the water is starting to run off the surface. Once this starts to occur, move forward along the top of the bond beam. If you continue around the entire pool, it should take approximately 10 minutes to complete the entire perimeter.
Gunite (concrete) is the day on which most people say their pool begins to take shape. While gunite only takes a day on average to install, this process needs three to four weeks for sufficient curing. During this curing process, several other phases of the project will ensue.
Typically installed 3-4 days after gunite, the tile and coping crew will install your tile, coping, and trim or spot tile selections.
Spray the gunite surface evenly, with a hose and nozzle adjusted to a mist spray or gentle rain, at least four times a day for at least five to seven days. Stand on the edge of the pool to do this and do not walk into the pool or on the gunite surface for at least three days.

The importance of this cannot be overemphasized. If the water is stopped, your plaster could develop a permanent ring at the level where the water stopped, or it could allow the exposed plaster to dry too quickly, and cause chips or cracks. Plaster is especially formulated to stay underwater at all times.
Shotcrete needs to be protected from rain until it obtains its final set, usually 4 or 5 hours. Following final set, it should be wet cured for at least 4 days, preferably 7 days if possible. The exposure to rain would prove beneficial as the rain would assure the presence of moisture for continued curing.
The 40°F minimum is standard. If the water in the concrete freezes, the concrete can be damaged. In my opinion, it should not have been done at freezing temperatures.
The best thing to do is spray the gunite with a hose 2-3 times a day for a week or so after it is shot. Helps keep shrinkage cracks to a minimum... so a light rain a few hours after it is shot is actually good for it.
In the Floor of the pool they typically want three inches of gunite below the steel and three inches above it. The walls are probably the same but not sure. In Cretan places like bond beam th may do twelve inches.
It is necessary for you to water cure your Gunite to slow the drying time down. In the summer, wet the pool down at least 5 times a day, more if you can get to it. In cooler months (temperatures below 80 degrees F), 2 to 3 times a day is fine. Spray water on the sides until it starts to “sheet” off.
One of the most important steps in gunite or concrete swimming pool construction is selecting the right type of waterproofing. Concrete is a porous substrate prone to water penetration; therefore, it has to be sealed to keep water in the pool, in addition to keeping ground water out, which is often forgotten.
Brushing thoroughly 1-2 times per week will prevent these materials from having the time to create a stain. Brush to Prevent Algae: Every pool can grow algae, but plaster, quartz, and aggregate finishes are more susceptible.
Custom Gunite pools are very durable. Among the different types of in-ground pools available today, Gunite pools last the longest and have the best warranties. This should be taken into account when considering the higher cost of Gunite pools. You'll get many more years of use from a Gunite swimming pool.
You could refer to gunite as concrete's cousin because they are both in the same family, but have their differences. Gunite is the dry mixed form of sprayed concrete. Gunite typically only contains fine particles in its mix while concrete contains both large and small particles.
Gunite is considered fully cured in 28 days. Interior finishes of gunite pools need to be kept underwater or wet.
With the gunite method, the dry concrete ingredients are placed into a hopper and then pushed out pneumatically through a hose to a nozzle. The nozzle operator then controls the addition of water at the nozzle, turning the dry ingredients into concrete that is fully mixed by the time the material hits the host surface.

Coping should be installed first, and then the tile. If the installation proceeds in the opposite order, damage to the glass often occurs and the resulting repairs can be costly and time consuming.
After the plaster is applied, we leave the pool filling with your water supply. During the filling process, DO NOT STOP the water from filling into the pool. A stain or ring may form on the pool plaster surface where the water was stopped.
A common cause with pool cracks is from too-thin gunite used during the installation process. During the construction process, the gunite might not adhere properly to the steel framework. When this occurs, the gunite “rebounds,” or bounces back after application. Rebound gunite should be removed and thrown away.
