How do they get the plaster or other interior finish into my pool?
Plaster will be applied and the plasterers will start your hose going to fill the pool as soon as they are done. DO NOT TURN OFF THE WATER UNTIL YOUR POOL IS FULL! Let the pool fill all of the way up until it reaches about an inch below the deck. This is slightly overfilled, but you will be backwashing and it helps to have a little extra water in the pool until the plaster dust is filtered out. Follow the plaster care instructions given to you by Houston Cool Pools. The plaster may appear a little mottled because the plaster does not dry evenly (yes, it really does dry under water). Some parts stay wet longer and so they appear darker, like a wet spot on a shirt. Brushing the pool and chemical balancing are extremely important on a plaster pool.
