How do I properly cut and install ClarkDietrich BS-10 Big Stick Composite Corner Bead for a flawless finish?

Achieving a professional finish with your ClarkDietrich BS-10 Big Stick Composite Corner Bead is straightforward when following these steps. First, precise cutting is key: Measure your wall height and subtract 1/2 inch. Use either scissors or a utility knife to cut the Big-Stick to this measured length. Ensure the ends are cut at a 45-degree angle for a snug fit. Next, installation involves several key steps. Apply a generous, smooth coat of all-purpose compound to the corner using a 4- or 5-inch taping knife. Press the Big-Stick firmly into the wet compound, making any necessary adjustments to ensure a straight line. Wipe down tightly with the taping knife, focusing on the outer edges. Immediately apply a light skim coat of compound over the surface, wiping it down smoothly. Allow this coat to dry completely, typically overnight. For the final steps, apply a final coat of compound using a 6- or 8-inch taping knife, feathering the edges beyond the previous coat. Again, allow ample drying time, ideally overnight. Finally, for the finishing touches, lightly sand the surface with 120-grit sandpaper. The composite material of the Big-Stick eliminates the fuzzing common with paper or mesh tapes, resulting in a smooth, professional finish.
