Pool resurfacing in Michigan

[MirGSS]

House purchased almost 5 years ago with a pool that was built in the 70s. Unfortunately have no real history on the construction, e.g. what was used to paint it, if/how it's been painted since then, etc.

I've been wanting to repaint or do something since we moved in, but we are finally to the point where the bare concrete is exposed in places, and algae just loves to grow there - and stick!

What are my options? Are there any resources or guides out there?

P.S. if this matters, we also want to redo the tile line at the same time, as they are old, have scaling, and are broken/cracked in places.

Pics (hopefully) attached to exhibit what it looks like now.

You need to have the remaining plaster chipped out to expose the underlying gunite. Then new plaster will be applied over the gunite. You don't want to paint. If you want colored plaster, you can get it, but be aware it shows flaws more than white or light-colored plaster. And knock out the old tiles and install new ones.

My pool took 3 guys with jackhammers to remove the plaster. See my photo in this post.

This might be a good time to look into why the main drain is plugged. It's not essential to have it operational, but some of us like it to aid circulation.

If your pool equipment is as old as your pool, it will be an opportune time to replace it all while the pool is empty. You can lose the tablet feeder while you're at it.

Hey, @MirGSS , did I shock you into stunned silence? Yes, you have a Project on your hands. Feel free to come back with any questions you may have.

We did a full resurface of our 70's pool a few years back (first resurface was 1998). We chose sandblasting over chip-out, took half a day and left the gunite shell spotlessly clean. Gave us an opportunity to check for cracks or other signs of trouble (looked perfect). Then another day to resurface. Expect to get 18-20 years out of the new plaster.
