When it becomes Rough; u start to see brownish stains that won't come off, Indicating that the cement cream has gone and only the sand stays behind allowing gunite to bleed through.

THis may be due to bad plaster or just the years have come : The plaster start to pop off or hollow spots ex: u know it's hollow because when u walk on it, it feels mushy.
