Finish types
The Main Venetian Plaster Finishes Compared
Ask for Venetian plaster and you will be shown four or five quite different finishes. Knowing which family you are looking at makes the conversation with any applicator far more productive.
Grassello, the high-polish classic
Grassello di calce uses a very fine marble aggregate and is burnished hard, producing the mirror-like surface most people picture when they hear the term Venetian plaster. It is the most reflective of the family and the least forgiving of a substrate that is not flat.
Use it where the wall is a deliberate statement and the preparation budget allows for genuine flatness. In a room with strong directional light it produces depth that reads as translucent stone rather than as a coating.
- Texture
- Very smooth, fine aggregate
- Sheen
- High, approaching a mirror polish
- Substrate demand
- High, any undulation is visible
- Best for
- Feature walls and reception spaces with directional light
Marmorino, the versatile middle ground
Marmorino uses a coarser marble grade and is typically finished matt to satin rather than mirror polished. The result reads as a soft stone with gentle cloud movement, and it is far more tolerant of a slightly imperfect wall than grassello is.
It is the workhorse of the family and the finish most often specified across a whole room rather than a single wall. It also takes deeper pigments without looking heavy, which makes it useful where a scheme needs a saturated colour with texture.
- Texture
- Fine to medium, subtle stone character
- Sheen
- Matt to satin
- Substrate demand
- Moderate, more forgiving than a high polish
- Best for
- Whole rooms, deeper colours, everyday interiors
Travertino, the textured stone imitation
Travertino finishes are worked to reproduce the open, pitted, horizontally banded character of travertine stone. The technique introduces deliberate voids and directional movement, so the surface has genuine relief rather than only tonal variation.
Because it is textured, it hides substrate imperfection well and copes with larger areas without looking flat. The trade-off is cleaning: an open texture holds dust in a way a burnished surface does not, which makes it a better choice for walls than for surfaces that are touched.
- Texture
- Pronounced, banded, with deliberate voids
- Sheen
- Matt, sometimes with polished highlights
- Substrate demand
- Low, texture disguises minor variation
- Best for
- Large walls, hospitality interiors, statement surfaces
Stucco lucido and the waxed finishes
Stucco lucido refers to the polished and waxed treatment as much as to a distinct material. Wax deepens the colour, raises the sheen and adds a degree of water resistance, and it is what gives many showroom samples their striking richness.
Waxed finishes need a little more thought about location. They deepen with age and respond well to occasional re-waxing, but they should not be cleaned with detergents, and they are not the right answer for a surface that will be wiped down regularly.
- Wax deepens colour and raises sheen noticeably over the unwaxed finish
- Re-waxing refreshes the surface without reworking the plaster
- Avoid detergents, which strip the wax rather than clean it
- Consider a breathable mineral sealer instead where cleaning matters more
Choosing between them
Work backwards from the wall rather than forwards from the sample. How flat is the substrate, how much light crosses it, how close will people stand to it and will anything touch it. Those four answers narrow the family quickly, and only then does colour become the interesting question.
On a scheme with several spaces, mixing families deliberately usually reads better than applying one finish everywhere. A textured travertino in a circulation space with a polished grassello on a single feature wall gives contrast within the same material language.
Always view samples in the room's own light. A polished sample under a showroom spotlight tells you very little about a north-facing wall.
Comparing the finishes
Narrow it down on real samples
These finishes are impossible to choose properly from photographs, because the whole point of them is how they handle light. Tell us about the wall and we will put the realistic candidates in front of you as samples.
