However, muriatic acid only eats away the cement surface around the pool aggregate (quartz, pebble, marble chip, etc.) causing a rough finish, weaker plaster, and most of the time worst results than prior. Remember cement is the base of ALL POOL PLASTERS. Salt. Results obtained suggest that adding salt does indeed have a negative effect even on good quality plaster if added at startup and up through the first two or three weeks. When salt is added to water the pH of the water begins to increase significantly (higher than normal).
This indicates a loss of calcium hydroxide from the plaster surface is occurring. This likely causes an increase in the porosity of the plaster finish, which weakens and ages the surface prematurely. Rough over exposed aggregate surface due to excessive use of muriatic acid trying to repair plaster surface problem.Pool Plaster surfaces with a course sand paper feel will cause skin abrasions, irritation, and bathing suit damage.
