After cutting to size and hanging drywall sections to both the ceiling and floor, the drywall seams are taped and the outward corners covered with corner beading. Though conventional paper tape is used, fiberglass sticky-sided mesh tape makes the job easier and requires no application of compound prior to fitting the tape. Drywall compound, though available in powder form to mix yourself, is also available pre-mixed so that the correct thickness is not an issue.
Apply Mesh Tape And Beading
Pull a section of mesh tape from its roll, and cut it to the required length using a utility knife or scissors. Apply mesh tape to all drywall seams with the sticky side against the wall and the drywall seam running along the center of the tape. Run your hands along the installed sections of mesh tape to ensure that it is secured firmly to the drywall surface.
Apply Corner Beading
Cut all sections of corner beading to the required length, position them against the outward corners of the room, and hammer 1 5/8-inch drywall nails through the sides of the beading into the wall.
Apply Drywall Compound
Pour some pre-mixed drywall compound into a drywall tray. If the compound is too thick, pout a little water into the tray, and mix it with the compound using a 6-inch drywall knife. Scoop some compound onto one side of the 6-inch drywall knife. Apply a thin layer of compound over all mesh tape with the knife, feathering out the compound, or smearing the compound past the edge of the mesh tape onto the wall, decreasing its thickness as you go. This will help the eye not detect that the taped areas stick out a little from the overall drywall surface. Apply compound to the corner beading, as well as all screw and nail heads. Wait at least 24 hours for the compound to dry fully.
Sand The Compounded Areas
Sand all dry compound first with medium and then fine sandpaper to remove all bumps or ridges. Make sure the compound is smooth to both the eye and touch. If any tape, nail heads or corner beading can still be seen, apply a second coat of compound and wait for it to dry and sand it again.
