How often should you resurface a gunite pool?
Another word you can say for plaster could be stucco. Often times it is also referred to as plaster of Paris.
Summary: A mixture of cement and sand sprayed onto contoured and supported surfaces to build a pool. Gunite is mixed and pumped to the site dry, and water is added at the point of application. Plaster is usually applied over the gunite. The plaster is actually the material that is visible and that comes into contact with the water (not the underlying gunite cement structure). More details: "Gunite" is a trade name for "dry gunned" concrete, invented and patented by a North Carolina man. The term "gunite" has been used so much that, to most people, it means spray applied concrete. People often talk about a gunite pool -- meaning a concrete pool where the concrete is pneumatically applied or sprayed in place using air pressure. Many of us in the concrete spraying business have started using the term "dry gun" to delineate this process. "Dry gun" means the cement and sand are injected into an air stream conveying it to the nozzle. The nozzle operator then adds the water at the nozzle and has total control of the water-cement ratio. The delivery hose of the mix is generally quite light, as the hose is mostly filled with air containing the mix of cement and sand.
Gunite is a mixture of water, cement, and sand applied through a pressure hose to produce a dense layer of concrete. This is used most often to line tunnels and repair structures.
I expect that the pool has a history of algae growth. Algae often forms itself in a circle, eating away the gunite underneath it.

AN adhesive plaster will soak blood up and stop it spreading around. Change them as often as possible.
PebbleTec lasts longer than plaster (and is usually warrantied for longer than plaster). In addition, it is darker so typically hides the staining that often comes with pool chemicals.
Kitchen cabinet refinishing means that you keep all components of your existing cabinetry and simply change the color or the finish which is often completed via hand sanding or chemically stripping the existing finish from the wood, then applying new paint or stain.
Gray in white plaster is usually trapped moisture and will often go away as the plaster hydrates. If it does not then they can be removed by draining the pool, acid washing the area, heat it carefully with a torch to draw the water out and then polish the plaster smooth. This should absolutely be done by a professional experienced in this type of remedy. A ZERO alkalinity treatment may also work with the water still in the pool. Again, pros only. Trowel burns can also cause gray in pools but you need someone familiar with this to properly diagnose the cause. If the plasterer is an NPC (National Plaster Council) member a tech advisor may come to look at the pool and diagnose it properly.
The reaction will often occur at the surface of an object.
