Vinyl liners need not be resurfaced. In essence, they are thick plastic bags housed in a structure below the ground. However, most liners need to replace after a period of five to 9 years.
The plaster's coating or surface will wear over time and need to be resurfaced. Your pool might need to be resurfaced every ten to 20 years, depending on where it is located. First, cracks and spalling must first be repaired. Then, the whole pool shell must then be prepared. Preparation is a process that removes plaster from the surface and prepares it for new plaster layers. Preparation can be done using sandblasting, chipping and chemical surface etching.
Although it’s used to construct pools, sometimes fiberglass is also used to resurface concrete ones. Theoretically, fiberglass should be superior to plaster because it’s waterproof, so it withstands stains, has a very smooth texture, and is available in many colors.
