Ceiling seams
 
The previous homeowner nailed 3 inch wide floor boards to the ceiling in the entire house. I took the boards down from the bathroom ceiling. The boards are nailed at every joist. So, I had to do repairs every 16 inches. I managed to do a great job in the bathroom and I only have a few spots in my seams/repairs that are slightly noticeable.

Having achieved the task in the bathroom, I tried to do the same job in the much larger kitchen. Unfortunately, I just primed the ceiling and it looks like crap. Most of the 'seams' created to repair the nail holes are visible to varying degrees. After priming, I checked the seams with a 12inch knife and they are humped...I sanded with a sanding sponge and was constantly checking the seams with my hand and i thought they were flat but obviously not. Now, given that seams are only 16 apart, what can I do? I know the seams need to be fanned out wider, but since they are not that far apart will it be worth the effort? I feel like I did the same thing in the kitchen as the bathroom but the result in the kitchen is horrible.

The choices I made were based on not having a helper to hang new boards, the only drywaller within 2 hours is very busy but also not the most reliable, I was confident from doing a good job in the bathroom.

And, I just measured a couple of the visible seams and they are approximately 6.5-7inches wide so pretty narrow.

It would be great if you could post a picture so we can wee what your seeing.
Most likly just not enough sanding and the seam was not covered out far enough.
6" is not wide enough, that just bearly wider then the tape.

In the ceiling, there are, I think, 5 regular seams with tape. The rest of the seams don't have tape as I simply cut out the damaged drywall and filled with mud. Due to the amount of holes along each joist, I essentially ran mud along the entire length of each joist.

I am finally ready to have this ceiling textured. The ceiling seams still bother me and I have an urge to rip the drywall down and put up new sheets. I am having a knockdown texture down on this ceiling but am concerned that the seams will show. Will knockdown conceal the seams?

As Joe stated, you need to feather those seams out more to get rid of the hump. Texture hides a lot of things but those humps will telegraph through the texture. Most people won't notice but you will know they are there since you did the work. No need to rip down the drywall, just finish those joints properly before texturing.

Since there is a seam every 16 inches, do I have really have the room to widen the seams enough to get rid of the humps? (Not being negative just wondering). In my mind, I will be covering the entire ceiling to get rid of these humps.

Well with a hump you will need to level those humps out with mud on each side of them. Use your drywall blade as a straight edge to see exactly where some "fill" is needed and run at least 6 inches of mud on the sides of the humps. You don't want to put any more mud on the high spots as this will only make each hump bigger.

I will give it a shot tomorrow.

Yes they will show and the ones you didn't tape will over time probably crack.

Yeah, I figure they will crack too. I am ripping it out and starting from scratch like I should have in the first place.
