Gunite, marcite, and concrete pools are the same thing, just different names for them. Complete Pool Re-plastering Every 3-7 Years at $3500.00 to $8000.00 NO JOKE! Excessive Use of Electricity – because pump must run longer, to inject more chemicals, to keep algae from building up in the concrete poors.
Advantages: Tile is the longest-lasting interior finish for a concrete pool. Tile is easier to clean than exposed aggregate.
Marcite is also the most affordable option for a new pool or replastering an existing one. With properly maintained pool water, it will last 8 to 12 years.
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.
A poorly built Gunite pool certainly has the potential to crack. But a properly built Gunite pool can and should last for 100 years or more, with no risk of cracking whatsoever. We've been building Gunite pools for more than 40 years (more than 4000 swimming pools), and we've never had one crack yet.
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.
When you are swimming, you would get scratched or roughened when you step out of the pool. Also, you could get scratched or your swimsuit could get torn with the jagged plaster. If it's unpleasant to run your hand along the side of the pool or climb up the stairs then its because your plaster is wearing thin.
Gunite generally allows builders to take more time to complete the project properly, since they can stop and start as needed. Gunite tends to be less expensive than shotcrete, and it can result in fewer errors in the construction process.
Concrete, when applied using the shotcrete process, or cast-in-place, needs to cure for 7 days. Water is the best curing method (7 continuous days).
Gunite and shortcrete are essentially the same material, but they are applied with different processes. Gunite is the popular trade term for dry-gun concrete, while shotcrete is the common term for wet-gun concrete.
Marbelite (marcite)
Standard white marbelite is a simple mixture of two-part white marble dust aggregate, one-part white cement, and water mixed together in a mortar or drill mixer for a minimum of six minutes to a consistency of a thick milkshake.
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.
Gunite and shotcrete are alternative forms of concrete, distributed by a hose at a high velocity, which enables us to reach awkward surfaces such as tunnels, bridges, swimming pools and train stations.
It varies depending on the type of pool, with plaster or cement pools needing to be resurfaced every 3-7 years while fiberglass pools can sometimes go as long as 15-30 years.
Many swimmers and children find the rough bottom in a gunite pool to be very abrasive and uncomfortable. It is not uncommon to scrape and or irritate your feet if the swimmer is in the pool for long periods of time and sitting on the pools steps or benches will certainly snag a swim suit.
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.
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.
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. The only thing I would be concerned about is a heavy rain while they are shooting it...
Traditional concrete is normally delivered to construction sites via ready-mix trucks, placed on the ground or in forms, and then vibrated for compaction. On the contrary, shotcrete does not require forming or compaction which increases application flexibility and creativity.
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.
For an unpainted fiberglass or gunite pool, epoxy is recommended. For pools previously painted with synthetic rubber or acrylic paint, your best options are premium acrylic or water-based acrylic. If the surface was painted with chlorinated rubber, premium acrylic would be recommended.
Brush the pool twice a day for the first two weeks. This opens the pores of the plaster to allow proper curing as well as removes any loose plaster dust from the surface. You may notice plaster dusting when you brush and the water becomes cloudy. This is normal and will go away with proper treatment and brushing.
It will chip and wear away more easily, and when it does, you will need to repair it. If there's a reason to use paint over plaster, it's that the application process really is a lot easier. While you could paint on your own, replastering is something that only the most industrious homeowners take on.
