Plaster help! Cause for concern ? Quartzscape finish today and pool filling

[mulli015]

Hello

After a year, I finally had my dream pool plastered today. Went with quartz capes. It is a very large pool(48k gallons) I am filling and in repositioning the hoses, I noticed that there were hairline cracks. When I tap on the area there is a hollow sound. Like really hollow. I can move 6inches to a foot over and there is no hollow sound. Installer is telling me it just hasn't finished curing yet and that when the pool fills the water will expand those areas and the hollow sounds will go away. i posted a photo of the cracking. there is more but this one stands out the most.

Thanks for any insight.

Can you provide a closer picture of the area in question?

Probably delamination.

It is not going away.

In my opinion, it needs to be redone.

Closer pictures actually show up less believe it or not. Those videos show that there is always going to be hollow spots. Does anyone here install these finishes that know whether the hollow spots or not are ok?

 

[JamesW]

It's not ok.

In my opinion, it needs to be redone.

Very much agree. I guess I am not sure how to support my claim with the builder.

He’s probably hoping it’ll not noticeably leak enough for a long enough time that he loses your phone number.

Maybe take a video of the sound before the water fills up.

Hallow spots are a sign of improper application/mixture, they are not a normal occurrence in a properly applied finish.

I took a video. is there a way to upload it so all can see?

Load your video to YouTube, make sure to mark it PUBLIC, and post a link to it here.

It's holey, but probably not holy.

Remove all hollow plaster and redo it.

I would probably want all plaster removed and redone because there were obviously mistakes made that caused the plaster to not adhere correctly.

Yea, I might get the plaster manufacturer to review that.

Any pictures of the prep or install? Delamination of that size that early points to some kind of surface contamination or installation error.

Agree with James, I would want it all removed and prepped correctly.

Good luck.

The pool installer said that as the pool fills the plaster will hydrate and expand. The hollow sound and hairline cracks will both go away

Complete nonsense.
