How to Care for a Sgraffito Wall

The honest answer: a sgraffito wall wants the gentlest routine in the whole lime family — regular dusting, no scrubbing, no acids, and the pattern itself left completely alone — because the design is not printed or painted onto the surface, it is scratched through real lime, and the same fine incised lines that give it depth are also the one part of the wall you cannot clean aggressively.

What makes the care different from a plain plaster wall

Sgraffito is two coloured layers of real lime plaster, with the top layer scratched away while still soft to reveal the colour underneath — a genuine relief pattern cut into the wall, not a stencil or a hand-painted motif sitting on top of it. That construction is exactly why the care routine is stricter than a flat lime finish like grassello di calce or intonachino: the incised lines are physically recessed, they collect dust the way any groove does, and — unlike a smooth wall — you cannot run a cloth or a brush across them with any real pressure without abrading the crisp edge that gives the pattern its shadow and depth.

The everyday routine

Dust it the way you would any lime feature wall — a soft, dry, long-haired duster or a very soft brush, worked gently along the direction of the pattern rather than scrubbed across it. That lifts settled household dust without touching the incised edges. For most sgraffito walls, kept indoors or under genuine shelter, this is the entire routine, done as often as any other feature wall in the house.

What to never do to it

• No scrubbing, ever. The incised lines hold dust because they are physically recessed — that is by design, not a flaw to fix with pressure. A stiff brush or a scouring pad works through the fine edge of the cut faster than decades of normal wear would, and once that edge is softened, the shadow line that makes the pattern read crisply is gone for good.
• No acids or descalers. The wall is lime, top to bottom, under the pattern as much as in it — vinegar, limescale remover and most bathroom sprays etch lime on contact, the same rule that governs every lime finish we apply.
• No pressure-washing or hosing. Sgraffito belongs on interior walls or genuinely sheltered exterior panels, never in standing or driven water — a wet cloth for an occasional mark is the ceiling of what the surface should ever see.
• No “touching up” the design by hand. The pattern is permanent once cut — that is the whole point of the technique, the design lives in the plaster rather than sitting on it — and it was never meant to be repainted or re-scratched to freshen it. If the wall genuinely needs restoring, that is specialist re-plastering and re-cutting, the same craft as the original commission, not a maintenance task.

Why there’s no re-sealing or re-waxing cycle here

Unlike encausto or pastellone, sgraffito carries no wax skin and no fixed reapplication schedule — it is bare, breathable lime left to carbonate and harden with age the way the whole lime family does. That means less upkeep, not more: no re-wax date to track, no sealer to renew. The trade is that the surface stays more delicate to contact throughout its life, which is exactly why it belongs on walls you look at rather than walls you lean on, brush past constantly, or wipe down daily.

What a sgraffito wall is honestly not built for

This is a considered feature wall, not a working surface. A busy corridor where shoulders and bag straps brush the wall daily, a kitchen splashback, anywhere near constant handling — none of these suit the technique, and we say so before any design conversation goes further. If the brief wants the quiet warmth of real lime without the carved pattern’s fragility, grassello di calce or intonachino give the same authentic material with a routine that tolerates far more contact.

The one-paragraph care manual

Dust gently, along the pattern, as often as any feature wall. Never scrub the incised lines. Keep acids and pressure water away from it entirely. Leave the design alone — it was cut once, on purpose, to last. And treat it as a wall to admire, not a wall to lean on.
