It's time to replaster our 23 year old pool. In the past 5 years, black algae has been a problem. Have gotten several quotes to re-plaster. I really want the same solid white plaster that has been used for years but I have been told that the plaster today is not the same formula and that the black algae will come back thru. I have been told that if I plaster, it will only last a couple of years. My old plaster lasted over 20 years and has only started looking bad recently. I really don't like the pebble finishes due to the roughness and the fleck appearance. Any suggestions?

I don't know about old plaster vs. today's plaster, but...... are they not chipping out the old? I would want a total chip out down to the shell. You can run into problems with just plastering over the "old" plaster. If your old plaster is removed, I would suspect all the algae would go with it. If your water is balanced properly, the plaster can last 20 years. I'm sure someone will be along soon who can go into detail on a total chip out vs. just plastering over old.
@Desert Dog is right- you're going to aim for a total chip out before the new plaster is applied.

Link is dead or has a typo? I’d be interested in reading through it.
Thanks for the reply. They will be chipping out some of the plaster. Anywhere that is pitted, chipped, or holding algae. I hope somebody out there knows about plaster formulations and if it's true that they don't make it like they used to. My suspicion is that the pebble surface is about twice the price as plaster so they may be trying to "up sell"
Darn I don't know why that happens? Its the last article in the PoolSchool Construction page.

I would ask for a quote on removing all the plaster not some. You don't want the new plaster failing because of the 20 year old plaster underneath it.
