What type of cementgrate to repair old concrete pool?

Is gunite used to patch a 1970's era concrete swimming pool? I heard to get an expensive cement from a home improvement store, but want / need more info.

Would like ro use a salt water system. I know it is important to keep the paint in good shape to protect the concrete from salt water. There is not a special concrete needed for salt water, is there?

when you say patch, are you talking about cracks or big areas? What kind of areas are you talking about? Is pool painted now or plastered?

I suppose it is mostly a plaster like superficial surfacing.

Not cracks in concrete, but concrete is crumbling.

You would use finishing pool plaster.

Back in that era.... Gunite was used by Anthony Pools. It is a cement compostion mixed on site and applied under pressure from a gun. Our pool is a Sylvan Pool and is not gunite. It was some type of cement that was applied under pressure.

I've had to make some plaster repairs. Not too hard. Obviously the water must be below the area to be patched. Normally I won't make any repairs until I empty the pool for painting. I had several areas where the tile had come loose. I used a powered grinder and pressure washer to remove the loose plaster. The patch area needs to be like a 1/4" thick or it won't hold up. The surrounding area needs to be acid washed and then neutralized before applying the plaster.
