On average, gunite swimming pools last 7 to 10 years before they need to be resurfaced. When that time comes, it's important to know what options are available so that you can pick the best choice for your backyard space.
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.
Gunite pools are incredibly durable and do not require a liner. This allows the pool to look better and retain its shape over time. One of the main disadvantages of a gunite pool is the time it takes to install the pool from start to finish.

If you're looking for a simple answer, the answer is yes. Saltwater chlorinators are perfectly safe for gunite pools. The biggest issues reported when using saltwater chlorinators with gunite pools have to do with the tendency of the plaster to stain over time when coming into contact with salt.
Start pouring your mixture of water and acid down the section of the pool you want to start with and wait for about 30 seconds to a minute for the acid to do its job. Scrub the area with an acid brush (found at pool supply store). After scrubbing thoroughly, take your garden hose and give it a final wash.
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.
Only pools constructed of plaster, exposed aggregate, or concrete are strong enough to withstand the power of a pressure washer. Any other type of pool, such as vinyl or fiberglass, must be cleaned using chemical treatments or using non-abrasive methods.
Unlike concrete, when building gunite pools, you can stop and start without any problems, which will help give a smoother finish. With a skilled nozzleman, the mix of cement and water can be adjusted at the point of delivery as required, while it is also less prone to cracking than concrete.
Durability. Gunite generally lasts longer and maintains a higher quality than shotcrete. For instance, gunite tends to dry faster than shotcrete, leading to a much smoother surface and avoiding significant cracks from shrinking. Gunite can also withstand up to 9500 psi, a much higher psi than shotcrete.
Hydrostatic pressure, or water pushing upwards, is the reason why pools can pop up out of the ground. To alleviate this problem, the majority of concrete pools are built with a hydrostatic relief valve.
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.
Gunite pools have been around since the '60s and are the most durable pool finish due to being made from concrete. The pool's structure consists of a steel rebar frame coated with a mix of cement, white sand or marble aggregate, and water.
The crew trowels the gunite smooth and lets it sit for a week or two before applying a smooth finish to the rough surface. The most popular finish is called plaster (actually a mixture of cement and marble sand), but a lot of people finish their pools with special concrete paint or pebble surfaces.
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. For gunite, builders load a pre-mixed dry material into the delivery equipment. Compressed air is then sent through a nozzle where it mixes with water.
Concrete (gunite & shotcrete) is a very strong material but not flexible. Just as soil movement causes a house foundation to crack, it can cause a pool to crack or shift.
Use a filter cleaner, or change the sand or cartridge if it's not been done in many years. Use clarifier to help coagulate suspended particles or use flocculant to drop particles to the bottom. Fill the pool high with water and vacuum the pool to waste, by setting a multiport filter valve to waste (sand or DE filters).
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.
Gunite pools use a rebar framework that is sprayed over with a concrete and sand mixture. Gunite is exceedingly durable, so swimming pools made of this substance are built to last. The versatility of gunite swimming pools means more than the ability to create an unlimited array of shapes.
An overly salted pool will generally not be a major problem (aside from salty-tasting water), but at levels over 6000 ppm there may be corrosion damage to some of the metallic equipment.
While they are easier to install, fiberglass pools are nowhere near as durable as a gunite inground pool. The inside surface of this type pool is a gel coat on which the fiberglass has been laminated. The walls of the pool are only ½ to ⅜ inch thick compared to the 8 to 10 inch thickness of a gunite pool.
Is a salt water pool easier to maintain? Yes, a salt water pool is easier to maintain! There's no need to purchase, store and add chlorine to your pool. Simply add salt and your pool's salt chlorinator will do all the work of making chlorine.
