Start by re‑seating loose screws or adding new ones beside pops, slightly below the surface without breaking paper. For hairline cracks, widen gently for better compound key, apply mesh where needed, and choose a quick‑set powder for the first pass. Keep layers thin, allowing full cure before widening coverage. Avoid building ridges at edges. With patience, the surface stabilizes structurally and visually, preventing cracks from telegraphing through primer and showing under unforgiving, modern lighting conditions.
Feathering creates invisibility. Load a twelve‑inch knife lightly, apply a thin coat, then lift pressure at edges so the middle carries thickness. Work in overlapping passes, always pulling into the previous wet edge. Sand between coats only when bumps exist; otherwise, scrape with a clean blade to knock high seeds. Each coat widens, not thickens, blending defects into a broader plane. Resist the urge to rush. Three calm passes beat one heavy application every time.
Trade chaos for control using a pole sander attached to a HEPA vacuum or a drywall sander with integrated extraction. Use fine grits and raking light to guide effort only where needed. Keep strokes broad and gentle, avoiding edge digging. Brush dust from corners with a soft block. Seal rooms still under containment while sanding and let the vacuum run briefly after stopping. The result is crisp flatness without coating every nearby shelf and sofa.
