I was told to brush my pool twice a day for the first 14 days after it had been plastered, why?

“Brush the entire pool surface thoroughly at least twice a daily to remove all plaster dust.” National Plasterers Council, NPC Start Up Card, September 2012 edition.

Brushing your pool twice a day for the first 14 days after pool has been plastered is one of the most proactive steps that you can take to protect your new investment and maximize the aesthetic quality of the pool finish. After the 14 days brush the pool at least once a week.
