Our bathroom was in need of a major update so we decided to tackle it ourselves. We managed to take down the old drywall (which had mold growing on it and the corner bead was rusted through) and put up new drywall all around, including some moisture resistant drywall. We tried to lay the tape, but it doesn't stick. When it does, the edges lift up. We are going for the texture-less look to match the existing plaster in the house. We have tried using a little compound behind the tape just to make it stick, but it doesn't, and this is on the horizontial joints. We don't even dare tackle the corners. Any help would be appreciated.
