   What kind of compound did you use for the first coat? (read what color was the bucket)   Did you use paper tape?

   I used the self stick paper tape with perferated holes and Gypsum drywall compound (blue bucket)for the first two coats then topping compound (green bucket) for the last coat.

   I think you got it backward.  Green bucket goes on first and blue bucket goes on second.  This would cause your cracks.You get out of life what you put into it......minus taxes.

   Not necessarily true.  I know many of us think the blue stuff (Sheetrock brand Plus 3 Lightweight Joint Compound) is to be used only for the final coat, but USG recommends it for taping as well topping.

   Maybe counter intuitive, but according to the maker of the product, and assuming proper application, it should work. 

   This may suggest a different reason, maybe the combination of preforated paper tape (don't care for it myself) or too thick of a coat (s) without enough drying time in between => shrinking?  Don't understand what you mean by " The edge looks deckled." Is that the pattern of the holes in the paper tape? (If yes, there you go)

   If you haven't painted already, the only thing i can suggest is to enlarge the cracks with a V tool (can opener, or the carbide scribe used for scoring CBUs)and run another coat of mud  in the cracks, sand smooth...

   I had a similar problem on a recent job.  I used fiberglass mesh tape on the flats and paper in corners and Sheetrock plus 3 (blue bucket) for all coats.  I have used this system many times before and never had problems.  This time for some reason I got cracks coming through on some of the flat seams.   It frustrates the crap out of me because that has NEVER happened before.  I can't figure out what went wrong.   I am blaming the mesh tape I guess and from now on will only use paper.

   Actually you're right. I just wrote it backwards. Do you think I'll need to re tape or is there a filler product out there

   You put the mud on too thick.........thin coats means THIN

   The mesh tape doesn't help much either.

   You might try to fix it by putting a coat of setting type on it.............I saw a guy fix this once by rubbing calk in and mudding over it, but I think that is a crappy fix.

    

    

    When in doubt, get a bigger hammer!

   Blue bucket goes in the dumpster and there should be compound under the tape not self stick glue.It's Never Too Late To Become

   I'm guessing that the adhesive from the tape got on the face side as well causing cracks from not adhering well.

   The secret of Zen in two words is, "Not always so"!

   When we meet, we say, Namaste'..it means..

     I honor the place in you where the entire universe resides,

   I honor the place in you of love, of light, of truth, of peace.

   I honor the place within you where if you are in that place in you

   and I am in that place in me, there is only one of us.

   first coat= 45 or 90 setting -yeah you have to mix it but get to know it and it's worth the trouble and lack thereof afterwards.
