Calcium nodules in pools look like little calcium volcanos or blisters that ooze out of pool walls and floors. In this article we cover two opposing viewpoints about what causes calcium nodules, and lay out the facts that everyone agrees on. Then we'll discuss how to prevent and fix calcium nodules.
Believe it or not, swimming pools can leak in both directions. Most of us think of pool leaks as water escaping out of the pool, but this article is about water pushing into the pool from the outside from hydrostatic pressure.

I have never plastered a pool in my life. In fact, until this week, I had never even seen pool plaster being applied. To be honest, I did not even know the difference between plaster, cement, gunite, concrete, shotcrete, or any other type of -crete. Because of this utter lack of knowledge and experience, I thoroughly enjoyed my time at this year's National Plasterers Council (NPC) annual conference in New Orleans.
