How can paint seepage under masking tape be prevented?

Correct answer: Press the tape edges firmly and use controlled consistency

The governing concept is controlled paint application along a sealed masking boundary. Pressing the tape edges firmly closes small gaps, while paint of moderate consistency is less likely to flow underneath. Apply a thin, even coat away from the tape rather than pushing paint into its edge. Watery paint, a loose tape edge, or a thick buildup increases seepage and produces an untidy border, so option A is correct.
