Protecting the Star of the Show: Masking Every Rafter

Day twenty-two. A day in service of the single most important aesthetic decision in this house: the rafters stay exposed.

Patch inspection: passed. First, up to check yesterday’s roof repairs. The batten-foam-and-tile-fragment patches had cured tight and immovable. The improvised method is now officially trusted.

Masking, meter by meter. Before any more ceiling finishing, we ran masking tape along every rafter where it meets the ceiling plane. Three reasons, compounding: white cement splatter wipes off tape but stains sanded wood; peeling the tape after finishing leaves a razor-crisp line between white ceiling and dark timber; and later, painting becomes fast because the boundary already exists.

Everything about Doiok’s interior hangs on this junction — the rhythm of dark exposed rafters against bright ceiling bays. If that line is sloppy, nothing else matters. So: tape, carefully, everywhere.

Sanding off the past. The courtyard-eave rafters got their surface grinding — these will eventually be painted white on their exposed faces, and old paint plus raised grain would show through any coating. The sander didn’t remove every trace of the old white paint, but it leveled the surface to where new coats will sit evenly. Preparation, again, is the finish.

The hardest bays. Then the day’s main event: first-coat finishing on the ceiling’s most hostile territory — the irregular bays above the corridor light fixture that we’d been deferring for weeks. Too contorted for mesh, so the technique changed: X18 cement only, applied in thin repeated strokes with a small rubber spatula, almost like painting in mortar. One full bag of cement, one bay each, three hours side by side. Not finished — these bays refuse to be rushed — but the method is proven, and acrylic filler will complete what the cement began.
