Just checked the largest of the bubbles and they don't sound hollow to me.The plaster isn't adhered in those areas or there's an air pocket behind it. He is right that it is somewhat normal but that's an awful lot of them and those are areas that you could end up with a delamination. Take a screwdriver and tap the handle against those spots and see if it sounds hollow
Not sure what to do from here. I feel like this is going to cause trouble down the road.
We had the acid wash today and pool is being filled.
I have pictures so if there is a delamination I can at least back it up for warranty.
If this is visible with water I am inclined to try to make him replaster....or at least fight for it.
You think there is a case for replaster for cosmetics?
