I've been trying to find some info on here, but I haven't found what I believe is a similar situation. So I'm hoping you guys can help me figure out what to do with my pool. It's a 18 x 38 free form/kidney bean shape, ~25,000 gal. I don't know the history of the pool, as I've only owned the house for 2 yrs. I do know that it was built in the late 1970's, has fiberglass wall panels, about four ft tall, and that the bottom is concrete. The fiberglass is blistering in lots of places, which I was planning on scraping and patching with a 2-part fiberglass repair kit that claims to be for use in pools and is paintable.
I don't have big money to spend, and I was looking at using olympic's zeron epoxy paint, as it was the only option I could do myself, and from what I read, it was compatible with the fiberglass. I didn't believe that there was plaster under the paint (on the concrete) However, the further I dig into this, the more questions I have.
#1 question: From the picture(s) (attached), would you say that the white layer between the blue paint and the concrete is plaster? It seems thin for plaster, but thick for paint. Any way I can chemically test to see if it's plaster?
When I started pressure washing the pool, the white paint on top seemed to come off pretty easily. The blue paint underneath doesn't come off as easily, and the pressure washer tends to cut down to the concrete by the time the blue comes off. I used the Kelly website bulletins to test a piece of the blue paint in some xylol, and it appears to be chlorinated rubber paint. They do offer a primer to convert existing chlorinated rubber to epoxy. But I'm leery of painting over the blue, since you can see the white underneath in so many places.
#2 question: What the heck do I do now?
I'm not even sure what else to add right now, but I can add more as your questions (and hopefully ideas) come up. Thanks in advance for all your help. I really enjoy reading and learning from others on this great forum!
