I finished the pool in July and check the water every week, adjusting it as needed. But these lines started showing up, and I thought it might be etching, but I can’t find any pictures that look like this. Thanks for any help!

Check if it’s cracking—it’s totally normal.

Was it really hot when they put the plaster on?

Search for “pool plaster crazing” on Google Images and check if it looks like your problem.

I’ve had them since last summer too. I don’t know why, but I’m interested.

@CurrentCrazeI asked my pool company about it and will update you soon. It seems like crazing, but I haven’t seen anything exactly like this before.
