Step 4: Smooth tape

• Starting halfway along the joint, hold the 5-inch knife against the tape at a 25-degree angle to the wall.
• Pull knife to one end of the joint in a single stroke, smoothing the tape and pressing it firmly into the compound.
• Scrape excess compound from the blade into mud box.
• Return to the starting point and repeat in the other direction. (This technique prevents tape from pulling off wall.)
• Repeat Steps 2, 3, and 4 on remaining walls or ceiling.
