What technique is advised to achieve a straight edge when using painter's tape?

To achieve a straight edge when using painter's tape, pressing the tape down firmly and burnishing the edges is the recommended technique. This process ensures that the tape adheres properly to the surface, preventing any paint from bleeding underneath it. When the tape is tightly pressed against the surface, it creates a seal that keeps the paint contained to the intended area, resulting in clean, sharp lines.

Burnishing the edges, which involves running a fingernail, a spoon, or a burnishing tool along the edge of the tape, helps to press it down even more and eliminate any air bubbles or gaps. This is crucial for achieving a professional finish, as even the smallest imperfection can result in a messy edge.

In contrast, applying the tape loosely can lead to gaps that allow paint to seep under, compromising the straight edge you are trying to achieve. Using a brush to apply paint over the tape is not advisable because it can cause excess paint to pool or seep under the tape. Lastly, removing the tape before the paint dries can also be a double-edged sword; while it may prevent the tape from pulling away dried paint and creating a jagged edge, it can also result in a less precise line if not timed perfectly. Therefore, the
