PREPARATION / JOINT FINISHING

Drive nail heads below panel surface without damaging paper face. Fill space between panels with compound using 5″ knife, center and press in joint tape. Tightly embed tape with knife, remove excess compound and apply it as a thin coat over the tape. Spread smooth with long parallel strokes. Apply compound over nail heads. When dry, use damp sponge to smooth any uneven surface. Apply second coat alongjoints using 8″ knife smoothing out 2″ inch beyond first coat. When dry, smooth surface with damp sponge. Apply a thin finish coat over second coat alongjoints using a 10″ knife and nail heads using 5″ knife.

JOINTING INSIDE ANGLES

Apply compound to both sides of angle using a 5″ knife. Fold tapes along its centerline to press into angle and embed with knife. Remove excess compound and reuse over the tape by skimming over with a thin layer. When dry, use a damp sponge to smoothen any uneven surface. Apply a second coat as a finishing coat, feathering outside the edges of the first coat slightly.

JOINTING OUTSIDE ANGLES

Fasten metal corner bead. Apply compound into perforations in the corner bead and even out excess compound. Ensure that the finish coat is dry and damp sponge to smoothen any uneven surface. Repeat with 2 more coats using 8″ & 10″ knife. For best results, wet sanding with sponge. Wait until compound feels dry to the touch. Saturate sponge with water, wringing out only enough water to eliminate dripping. Rub joints gently using a sweeping motion to remove high spots with as few strokes as possible. Clean sponge
often. If dry sanding, use 150 grit sandpaper wrapped around a piece of wood to avoid scuffling panel paper.
