crack In drywall

blue collar

I just finished priming the wall and where the new drywall meets the old drywall I noticed a hair line crack where I taped the joint. It was not visible before I primed. I guess it's best I remove that cracked area and re-tape and re-mud. I used paper tape this time when I normally use the mesh type tape wish I had of stayed with the mesh tape. If anyone has an easier solution Im all ears. Totally frustrated my wife is going crazy with all the dust Im kicking up with the sanding.

It means that the gypsum was not secured properly. Is there a stud at the point that the two sections meet?

There should be no sanding needed until it's been mudded at least two times.
Just use a dry wall knife to knock off the high spots and add another coat until it's time for the last coat.
Just running a shop vac with the hose under the sanding pad will cut down a lot on the dust.
I also use a cheap box fan blowing out as I'm sanding to keep down the dust.

Joe its been mudded 2 times already I never expected this to happen thats why I figured it was OK to prime. Every thing looked fine.
