Pool resurfacing

[ettienne]

I have a 40,000gal 40x20 pool built in 1982. It was resurfaced with DiamondBrite about 10 years ago by the previous owner and the DiamondBrite is failing miserably. So it looks like it's time to resurface again.
I started researching the process before contacting contractors.
Is 10 years about the expected life for DiamondBrite? What about other products?
I gather that painted surfaces do not last as long as plastered products.

I don't know much about pool resurfacing but there are some people here who do. One of them should be along shortly to answer your question. Welcome to the Pool Forum!

Concrete pool finishes can last longer than 10 years, but those that do are (a) skillfully applied and (b) in pool with well managed chemistry.

If you Diamond Brite is de-laminating . . . that is most often an application failure, though draining a pool and leaving it empty can also cause delamination. If it's eroding or dissolving away, that is more likely a pool chemistry problem, but again, application matters.
