What happens here
Begin by applying a layer of drywall compound (mud) to all seams between drywall sheets. Embed paper or mesh tape into the wet mud, then apply another thin coat over the tape, feathering the edges. Allow to dry completely. Apply additional coats of mud, feathering wider with each coat, to hide seams and screw depressions. Once dry, lightly sand all areas with 80-120 grit sandpaper, being careful not to sand through the tape. For corners, use 3M adhesive corner spray or mud to attach corner bead, then mud over it. Finish with a skim coat, a very thin layer of mud over the entire surface, to ensure a uniform, smooth finish. Sand lightly after the skim coat dries.
Goal: Apply drywall tape and mud to all seams and screw holes, followed by sanding and a skim coat to create a smooth, paint-ready surface.
