ceiling seams very noticeable (new construction)

MnDrywallRanger

I have seen broken edges like that too many times with my years of experience in drywall. They are often caused when forklifts move a stack of sheetrock and knock the stacks together... or when loading the stack with a boom truck...or when they stock the job they may drop the sheets a little.

All those broken spots must be cut out and cleaned out. Then prefilled with a setting compond mixed fairly thick. Then taped...

I wonder if the taper cleaned out all the broken blisters on the factory edge before he put the tape on?

Anyways that is a knockdown ceiling texture that cannot be scraped off if painted over.

It appears the taper humped the seams with too much mud. I can even see humps in the field for some reason...almost looks like they built up mud on screws sticking out or something?

The only options to fix your ceiling is to...

*Spray with acoustic (popcorn) ceiling spray..or

*Skim coat the entire ceiling. Flash the ceiling with a 500w light close to the ceiling with the other lights off if possible and shine (shadow) down the length of it to expose the bad seams or any broken blisters that may not have been cut out and filled, and then fix the broken (blistered) rock and feather out the seams accordingly..or

*Put another layer of sheetrock over it and re-do..or

*Tear the ceiling rock off and re-do

I feel for you...fortunately for me there are a lot of shotty tapers out there and a shortage of decent tapers...which made it easy for me to build a good reputation and keep busy.
