When is wall spackling enough
Wall spackling is enough when the damage is shallow, isolated, and the wall around it is sound. Small nail holes, picture-hanger marks, light dents, and minor surface chips can often be filled, feathered, sanded, and prepared for paint.
Spackling is not enough when the drywall paper is torn deeply, the hole goes through the board, the surface is moving, or the whole wall is rough. Those conditions may need patching, tape, skim coating, or replacement instead.
