Marmorino

One Material, Three Very Different Walls

Marmorino is the classic Venetian plaster - finely ground marble dust bound in slaked lime, applied in multiple thin coats and worked with a steel trowel. What changes the character of the wall entirely is grain size: a fine grain burnishes to a glassy, stone-like sheen, while a coarse grain stays matte and richly textured, more like carved stone than polished marble. It's the material behind the "old world Italian" look that's become one of the most searched-for finishes in coastal design and renovation photography - and the sample panel is what tells you which grain is actually right for your room.

Because it's lime-based, Marmorino is fully vapor-permeable - it lets moisture pass through rather than trapping it, which matters in a humid, salt-air climate where sealed acrylic finishes tend to fail over time. It performs as well as it photographs.

Choose Your Texture

Every Marmorino project starts with a sample panel applied in your own space and light - so you approve the real material, not a photograph of it.

Marmorino Fine

Silky and reflective - the closest Marmorino comes to solid, polished marble. Reads as refined and formal, ideal for statement rooms. Interior only.

Marmorino Medium

Visible hand-troweled texture with a soft, moderate sheen - refined without going glassy. Rated for interior and exterior walls, and the only grade cleared for sealed shower and a walls - the most versatile of the three.

Marmorino Course

Matte, heavily textured, and architectural in scale - Marmorino without the gloss. Commands attention at entries and can extend to protected exterior accent surfaces.

Why It Holds Up Here

Humidity, salt air, and storm cycles are hard on the wrong materials. Marmorino, applied and sealed correctly, is not the wrong material.

  • R
    Naturally Mold Resistant: Every grade in the line is manufacturer-tested as naturally anti-mould and breathable. That's lime chemistry at work across the whole product line — a real advantage in year-round coastal humidity, not a claim specific to any one grain.
  • Breathable by Nature: As a lime-based system, Marmorino lets trapped wall moisture escape rather than sealing it in - the opposite of what happens with acrylic or synthetic finishes in a humid climate.
  • Sealed to the Job: Interior Marmorino is sealed with natural beeswax for a soft luster and everyday moisture protection; exterior and high-traffic applications get a stronger protective wax specified to the location.

Four Steps to a Finished Wall

The same disciplined process on every project, whatever the room.

01

Sample & Consult

Site visit, finish recommendation, and sample board production - not a swatch or a photo.

02

Substrate Preparation

Walls primed and prepared to the standard Marmorino requires before a single coat goes on..

03

Hand Application

A minimum of three coats, hand-troweled and worked to the approved sample's depth and sheen.

04

Seal & Document

Beeswax or protective sealer applied, with a formula record issued for future repairs or matching.

Marmorino, Answered

Can Marmorino go in a shower?

On the walls, yes - Marmorino Medium is the manufacturer's own recommended grade for shower and sauna walls, sealed with their two-component wet-area sealer. Marmorino Fine is an interior-only, dry-area finish and isn't recommended for showers. On the shower floor or tray, Marmorino isn't the right material for any grade — that's a job for Hydrocement, which is built specifically for constant standing water underfoot. We'll spec the right combination for your bathroom during the sample consultation.

Can Marmorino go outside on the coast?

Marmorino Medium and Marmorino Coarse are both rated for exterior walls - Medium is even suitable for shower and sauna walls with the correct sealer. Marmorino Fine is an interior-only finish. Per the manufacturer's spec, exterior protective treatment on Medium is only strictly required in heavily polluted urban settings, which isn't a concern along this coastline, though we still recommend sealing for salt-air exposure. 

How long does a Marmorino finish last?

Properly applied and sealed, Marmorino can last decades - it's a traditional finish with centuries of precedent. Resealing every few years maintains its sheen and protection, and we document the exact formula used so future maintenance matches perfectly.
