The cheapest way to resurface a pool will depend on the size of the pool and the condition of the existing surface. Here are a few options that could be considered:
Patching and Painting: If the pool has minor cracks or chips, patching and painting may be a cost-effective solution. This involves filling in the damaged areas with an epoxy patching compound and then painting the surface with a pool-specific paint. While this is a relatively inexpensive option, it is not a long-term solution and may need to be redone every few years.
Vinyl Liner: A vinyl liner is a cost-effective way to resurface a pool that has a concrete or fiberglass shell. The process involves installing a new vinyl liner over the existing surface. This option is more affordable than plastering, but the liner will need to be replaced every 7-10 years.
Fiberglass Resurfacing: Fiberglass resurfacing involves applying a fiberglass coating over the existing surface. This option is more durable than patching and painting, and it can last up to 15 years. However, it is more expensive than patching and painting or vinyl liner.
Plaster: Plastering is the most traditional method of resurfacing a pool. It involves applying a new layer of plaster over the existing surface. While this is the most expensive option, it is also the most durable, lasting up to 20 years.
Overall, the cheapest way to resurface a pool will depend on the condition of the existing surface and the budget available. Patching and painting or vinyl liner may be the most cost-effective options in the short term, but they may need to be redone more frequently. Fiberglass resurfacing and plastering are more expensive, but they also last longer.
