Architectural finishes

Intonaco lime plaster walls in Los Angeles

Intonaco is the plainest of the lime finishes and the most architectural — the traditional flat render, troweled level rather than polished, so the wall reads as a solid material instead of a decorative surface.

What it is

Lime and sand or limestone aggregate, applied in coats and finished level. It is the base the other finishes are variations on — Marmorino is this compressed and polished, Roman clay is this made finer and burnished. Left as it is, it keeps a coarse, quiet texture.

Where it works

Whole rooms, commercial interiors and anywhere the wall should feel like part of the building rather than a treatment applied to it. It is the most forgiving of the family across large areas, which is why it turns up on the bigger jobs.

What to expect

Fewer passes than a polished finish and it covers ground faster, but the substrate has to be true — a flat finish hides nothing. Sealed or unsealed depending on the room; commercial walls always get a top coat.

The colour range

Intonaco in 20 colours

Rendered, not photographed · indicative only

Every colour here is the studio’s own, and every swatch is drawn from its hex value rather than photographed. Screens differ, and so does the light in your room — we make sample boards on site before anything goes on a wall, and that is what the colour is decided from.
