Pool chemistry and maintenance has a big effect on the life of the interior surface finish of a pool, so the average lifespans shown below are stated as a range instead of a single number. And, or course, there will always be a few outliers that fail sooner or last longer than expected.

• Plaster (Marcite) - 9 to 12 years, average 10 years

• Aggregate/Pebble Finish - 12 to 16 years, average 14 years

• Liner - 7 to 10 years, average 8 years

• Fiberglas Gel Finish - 14 to 18 years, average 15 years

Are they actually useful?
