Expected life of plaster

[miker1755]

My pool is 13 years old and showing signs of age, "pock" marks / rough spots where algae gets a start etc. I am being told that I am already on "borrowed time" as typical life of a plaster job is 10 years. Anyone here care to confirm of deny that "reasonable life expectation" concept or I am just being sold a bill of goods?

I've seen 30 year old plaster that was still in reasonable shape -- albeit tan in color. But plaster these days rarely seems to last so long.

Rough plaster does harbor algae, and is hard to fix. You can replaster, or refinish with epoxy paint.

I'd say that there is no set life span. Every pool is different, if you think about it. The quality of the workmanship when made, the quality of the water care during its life. My 1958 pool was fine until my father got old and lazy and just lost interest in taking care of things maybe 10-12 years ago. Today the plaster is deeply pocked all over. But it doesn't leak, so it's just cosmetic........for now.

My Marcite plaster lasted 14 years with three acid washes in northern IL. I'm on my second year with Pebble Sheen and so far I'm very happy with the finish. I'm under the impression that plaster doesn't normally last as long in colder climates?
