Start with adhesion testing and gentle scraping of the highest popcorn peaks if stable, then prime with a bonding or universal primer when needed. Apply a tight first coat to fill voids, let dry, and knock down ridges with a pole sander. Add a broader second pass, feather edges wide, and spot a third for perfection. After high-build primer, mark flaws with a pencil, touch up, then finish with flat ceiling paint.
Locate joists, snap layout lines, and pre-cut panels. With helpers or a lift, hoist boards and fasten into framing, ensuring screws pull tight without overdriving. Stagger seams, tape with paper tape, and apply two or three coats of compound, feathering generously. Sand lightly, prime, and inspect under raking light. Extend boxes, reinstall fixtures with code-compliant supports, then paint. Expect minimal dust and a very consistent plane across the room.
After confirming the old surface is sound and suitably primed, strike precise chalk lines from the room’s center to guide layout. Spread adhesive as directed, then set tiles carefully, pressing evenly and checking alignment often. Trim perimeter pieces cleanly and caulk small gaps for a crisp edge. For drop ceilings, level the grid meticulously. Finish with paintable caulk where needed, then step back and admire the instant architectural texture.
