Fiberglass pools can be compared to fiberglass boats by using a tough and smooth gelcoat. Gelcoat is long-lasting but can become brittle over time. A gelcoat that is damaged can lead to discoloration, chalking, cracking, blistering, and discoloration.
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.
It is also very affordable, compared with other resurfacing options. It can be rough to touch. Algae like plaster so you will need weekly maintenance and an acid wash every 3-5 year.
