After owning my house for 7 years its time to drain the pool and address the plaster. Basically, its wearing off in places. The pics below show the nature of it, even though it looks worse now that the pool is empty and dry.
I have a few questions;
-Am I correct in saying this is plaster? For a pool 30 years old is there anything else it could be (based on the pics below)?
-Is this normal wear and tear or accelerated by high PH (new SWG about a year ago)?
-Why the circles?
The surface is stable, not flaking or falling off (except for a couple flakey areas on the steps). Where its worn off is very thin, say, no more than a 1/16 inch. So I don't think it needs a filler or anything(?) For the "paint" I plan to do 2-part epoxy (probably the Olympic Zeron).
Before anyone says anything, yes I know re-plastering is better . The $$ for that just isn't an option right now.
I'll continue reading previous threads here on the repair process. If anyone has any good reading on preparing the surface for paint feel free to post a link. At this point I plan to do the acid wash, tsp, then rinse.
