plaster pool finish

The most common in-ground pools are concrete shells that have been finished with a type of Portland cement-based material, known in the pool trade as “plaster,” that seals and protects the shell. In many instances, the plaster is coated with paint, epoxy, or even fiberglass. The plaster can also serve as a substrate for tile.

Plaster, unlike fiberglass, reacts with pool water over its life span. Therefore, more chemicals may be required to maintain the proper water chemistry. You can counteract this problem by adding a "filler" to your plaster mixture.

Another popular finish for fiberglass pools is epoxy painting. It can take up to a week for it to cure. However, the result is a beautiful and smooth coating that looks great inside any swimming pool. Epoxy is also more affordable than other finishes, with an average cost of $1,500 for each application.
