But it’s not always sunshine and drink sipping out there. In addition to the routine filtering, chemical monitoring, and occasional frog skimming, you have to address the fact that a pool’s underwater surfaces deteriorate over time.
Most concrete pools in the United States have been plastered before they are constructed. There are many pool coating options available in the United States. These pool coatings can be applied to pools that have lost their original plaster or become stained and rough over time. Pool coatings are applied to the plaster. However, the plaster must be in good shape. It may be necessary to patch any spalled or broken pieces from the concrete shell below.
The good news? Once the pool is tiled, it won't require resurfacing for at most twenty years. With proper upkeep, it will probably last a lot longer.
