Cement board drywall outside corner.

This video transition between cement board and drywall joint or how to tap drywall and cement board joint or tapping cement board and sheetrock shows the tra. Cement backerboard is a thin layer of concrete with fiberglass mesh on both sides. Are you saying just use the metal paper corner bead install with drywall mud even on the cement board. I need to finish the outside corner above the shower alcove.

Keep the cement backer boards about 1 4 inch apart. The cement board is on the wet area the drywall is on the dry area forming an outside corner. It s available in sheets of many sizes with 3 foot by 5 foot sheets being the most common. After pressing the boards into the mortar screw them in with screws made especially for cement backer board installation.

Corner bead is most often associated with drywall. I will just end up painting it. Just as you would with drywall make sure the screwheads are slightly depressed below the cement backer board surface. Then just tile over the mud with thinset tile.

Where these two meet what is the proper way to finish it so it s a nice corner. It is a long strip of corner piece made out of aluminum paper or vinyl and is installed over a drywall corner giving the drywall a finished and professionally done look. At some point along the wall the cement backer board will meet with the drywall used in the rest of the room. This joint needs to be flush and smooth in order for the tile or other wall covering to be installed correctly and to create a professional finished appearance.
