Finishing Joints:
Apply a thin layer of compound to the tapered edge. Press joint tape firmly into the compound, while centering it over the seam and embed with a broad knife. Sufficient joint compound must remain under the tape to ensure a proper bond. Allow to dry. Apply a second coat of joint compound over the embedding coat and feather out beyond the first coat. Allow the second coat to dry thoroughly prior to application of the finish coat. Spread the finish coat evenly over the second coat and feather to a smooth uniform finish. After each coat had dried, sand or sponge smooth prior to the application of the ensuing coat.

Finishing beads and trims:
Apply first coat of compound to all the bead and trim and properly feather out onto the panel. Wet sand, as necessary. Allow the compound to dry thoroughly prior to the application of the second coat. Apply the second coat and feather at least 2” beyond first coat, allow to dry completely and wet sand, if necessary. Apply the finish coat and extend the compound slightly beyond the second coat. When dry, sand as necessary to provide a smooth surface for decoration.

Sanding:
Use 150 grit sand paper or finer. Remove high spots using as few strokes as necessary. Lightly sand imperfections while being careful to avoid scuffing the paper. When dry sanding, wear a NIOSH approved dust mask and eye protection.
