Cement Board Drywall Outside Corner

Corner bead is most often associated with drywall.

Cement board drywall outside corner.

Durock is a type of cement board that is water and moisture resistant. At some point along the wall the cement backer board will meet with the drywall used in the rest of the room. I need to finish the outside corner above the shower alcove. Are you saying just use the metal paper corner bead install with drywall mud even on the cement board.

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. 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. It s available in sheets of many sizes with 3 foot by 5 foot sheets being the most common.

Cement backerboard is a thin layer of concrete with fiberglass mesh on both sides. After pressing the boards into the mortar screw them in with screws made especially for cement backer board installation. 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. Then just tile over the mud with thinset tile.

I will just end up painting it. Whenever you re laying tile on a wood subfloor you need to first install cement backerboard to prevent leaks and water damage. The shower ceiling is hardibacker and the wall outside the shower is drywall. Where these two meet what is the proper way to finish it so it s a nice corner.
