How can a thick ridge of paint along masking-tape edges be avoided?

Correct answer: Apply moderate thin layers and avoid pushing excess paint toward the tape

The governing concept is controlled paint application at a masked boundary. Excess paint pushed against the tape dries higher than the surrounding surface and forms a ridge. Applying moderate, thin coats, removing excess paint from the brush, and working gently near the edge keeps the transition clean. Option A is correct; thick buildup, watery seepage, and repeated pressure all make the edge defect more likely.
