Cut drywall to size with a sharp utility knife and a straightedge. Smoothen the edges of the drywall with coarse sandpaper and a sanding block. Utilize homemade 2-by-4 T-braces to assist yourself and a partner when installing the drywall. Rent a cradle lift for assistance if you are installing the drywall panels yourself. Nail the drywall into place, leaving 6-inch (15 cm) intervals between the nails. Dimple the drywall by giving the nail an extra hit to break the surface material.
Snap chalk to outline where the edge of the vinyl meets the upper level of ceiling. Apply adhesive caulk to secure the bead in place. Staple the vinyl bead where it meets the lowered section. Attach the longer vinyl beads first.
