Hiding the Manifold, Skimming the Light Boxes

Day sixty-two. The three-man rhythm again — brother, me, Cheolsu-hyung — closing out bathrooms above and below.

Master bath: tiled. The final room in the tile campaign wrapped: floor laid and the accent tiles set — the room’s one flourish against the calm 600 mm field. Sequence note now confirmed across three bathrooms: walls first, floor last, so the floor tile tucks under the wall course and every edge shadows downward. The entry floor and the basin-zone upper walls in the annex closed out the same day.

The manifold disappears. The main bathroom’s finest small moment: the heating manifold — the valve cluster that every Korean bathroom hides somewhere awkward — got its custom cover box (the carpenters’ plywood work) wrapped in matching tile. Taped for curing now; the result reads as a low tiled ledge beside the toilet. Aesthetic goal achieved, and by accident a practical one: it’s exactly phone-and-cup height. Function follows form, occasionally.

The skim coat education. The bath partition wall and every ceiling light box got the all-putty treatment: Handycoat skimmed thin across the entire plywood surface (half a tub), then sanded after drying. Bare plywood under white paint always betrays itself — grain, seams, a lumberyard color bleeding through; the skim is what makes painted woodwork look like cabinetry. Working discovery: don’t fight for a flawless wet coat. Dust and pulls will leave fine ridges regardless — apply boldly, dry, and sand; Handycoat sands beautifully and the sander is a more patient finisher than the knife.

Lights: two-thirds in. Downlight positions laser-checked, holes cut, roughly 66% of the planned fixtures installed. The light boxes that were framing lumber two weeks ago now wash the ceilings exactly as sketched — down-glow below, halo above. Evening on site increasingly feels like the renderings we argued over in March.

What we'd tell you
Never paint raw plywood directly — a thin all-over Handycoat skim first, sanded after drying, is what separates furniture-grade white from painted lumber. Don't chase a perfect wet finish: apply boldly, accept the fine ridges, and let the sander deliver the final surface.
