Id ask him how long he's been in business, and tell him to get the damm lighting in, before you touch it.We're doing a Medical Office Building (framing, hanging and finishing - Level 4). Walls are finished, sanded, primed. There's NO permanent lighting on in the building and the GC super is shining lights down the hallways and demanding we come back to skim the walls.
We verified our guys left no humps at the joints and what he's seeing is differences in materials beneath the prime coat - and as humid as it's been, it's some over-sanding on the drywall paper flashing through.
We're telling him that the proper way to punch drywall surfaces is to do so under permanent lighting standing 5 or 6 feet back from the wall at a perpendicular angle but he's not accepting it.
I remember seeing this in the USG Handbook years ago but I can't put my hands on it right now. Even looked through the Gypsum Association website but came up short.
Any other suggestions???
Thanks.
