Recently I mudded and taped my bedroom with mesh tape however did not use a setting compound which in hindsight I should have used, anyways I am having a couple joints show hairline cracks on the butt joints and am wondering how to go about fixing them and blending it perfectly into the wall? Should I go over with paper tape or mesh again and do 3 coats? Also have had trouble in the past blending new mud over paint do you have any pointers how to blend it better, should I prime area before then mud then prime and paint area.

Would love any advice you can provide.

There is no need to use mesh tape on a standard joint. If you have cracks cut them out by making a V about 1/4" deep fill with as thick of mud as possible or use con fill. Tape with paper tape using taping mud not finishing mud or use all purpose if you must. Unless its a bevel joint your first coat should be 20" wide and thick enough so that you just barely cannot see the tape at all. 2nd and 3rd coats should be 2" wider than previous coats. Sand ridges before applying each new coat.

If you run a knife along the sides of the tape and then down across to cut if off past the crack and dig it out of the mud you can remud. Tape it with paper tape in that section. The wall will be easier to blend because you wont be going overtop and blending out.

In future avoid mesh tape its for the most part a pain to finish nicely.

Agree with Chett, cut out and con fill.
