We will respond with a big, "it depends." A properly maintained pool water chemistry will prolong the life span of your pool. Many pool owners, both homeowners and commercial property managers, keep their pools pristine well past the point when it is time to resurface. You can tell when plaster is starting to peel or flake, check cracking, becomes discolored, develops structural cracks and rust stains, paint peels off, or fiberglass fibers begin to wear off.
Fiberglass is often used to resurface concrete pools. Theoretically, fiberglass is superior to plaster as it is waterproof. This means it can withstand stains, has a smooth texture, and comes in many different colors.
Keep in mind, resurfacing a pool is not your average DIY project. Any small mistake can leave you with a leaking pool that can cause damage to your house and backyard.
