There literally are over 200 nail pops and all the seams are visible.
Any suggestions??
Ok, if the nail pops are from being high then screw them in. IF they are from blowing through the paper and vibrating out then not one of those screws is a screw. It does not exist and therefore the nail pattern is not to code.
First send a notice to your sub that you are billing back rework to him as he apparently does not know how to fix his men's mistakes or does not want to fix them. Let him know that you are documenting and recording ALL time for repair and will bill at company OVERTIME rates as you now must authorize overtime for other work to prioritize this work.
Take pics. Count the nail pops and circle every one of them in pencil. Then go back and tighten and or add screws. Then begin your three coats to refinish the surface.
Use your 12 inch knife and go along the seams. Check for light as mentioned. Take pics and drag your pencil in areas that need work to mark them. Float it out with 6 or 8 inch knife both sides and move toward 12 inch knife. Make sure the mud is DRY between coats or you can create more trouble, better to do it once now than redo it again.
Make sure that the CORNERS are sharp and clean, straight, and square as possible. If you can see wobbles in any corners they have to be fixed. Customers eyes see but brain does not comprehend; except that they feel like something is wrong. When corners are tight and square every customer does not notice what it is, but it feels RIGHT and GOOD.
Hope it all works out, either way you need to bill this idiot sub for your time, that includes extra management time and my time in response (smile). Ike sure and charge for lost paint and paint time. I hope you had a good hold back. Never less than 10% and never pay until you are positive all is well. I bet when you tell him all that you are going to do and charge for he comes and handles personally.
