I'm about to start mudding and taping sheetrock. I know i'm supposed to use tape for the inside corners...

Question

am i supposed to use tape where the wall meets the ceiling?...the ceiling is also sheetrock.

Answer 1

Use it at all the joints or it will crack, you need metal corner bead for the outside corners and be sure to use paper tape, the fiberglass tape is for repair work mainly not new joints.The crease on the tape should face the wall or it will get air bubbles behind it. Use an 8" knife to apply the mud in the seams and corners.

Answer 2

Yes, the tape is applied just like and inside corner.
