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.
