If gypsum boards at the joints do not have the factory bevel edge they certainly are cut at an angle of 45 degrees.It is necessary to putty deeply penetrated deep into the seam.Moreover, at the edges of the sheets should be no delamination of gypsum paper.If there is such a defect, who quit the board must be carefully trimmed with a knife and place primed.In more detail, as well as than to gloss over drywall joints.
