Marmorino is a traditional Italian lime plaster known for its matte, stone-like texture and warm, organic appearance. Unlike polished Venetian plaster, which reflects light like marble, Marmorino absorbs light — creating a soft, understated surface that feels grounded, natural, and timeless.
In Miami, Marmorino has become the finish of choice for homeowners who want the durability and breathability of lime without the high-gloss sheen of Venetian plaster. It performs exceptionally well in South Florida’s humidity, resists mold and mildew, and creates a calm, sophisticated atmosphere in any room.
Exotic Wall Finishes has been applying Marmorino in Miami since 2015. Our founder, Gian Carlo Sagasti, has been working with Marmorino since 2003 and was a model for Marmorino Tools Worldwide — the Italian manufacturer whose trowels are used by master plasterers internationally. That distinction reflects a level of mastery that very few artisans in the United States can claim.
Marmorino is a lime-based plaster made from aged lime putty and fine marble dust, applied in multiple thin layers and finished with a steel trowel to create a matte, textured surface. The name comes from the Italian word marmo (marble), reflecting the finish’s stone-like appearance.
Historically, Marmorino was used in Venetian villas and palazzi as a durable, breathable wall finish that could withstand humidity from the nearby lagoons. It was applied over masonry and lime plaster, and it aged gracefully — developing a natural patina that many designers seek to replicate today.
Modern Marmorino is available in a wide range of natural pigments and can be finished at different levels of smoothness, from nearly flat to deeply textured. What remains constant is its matte finish, its breathability, and its mineral composition.
This is the most common question we hear. Both are lime-based Italian plasters, and both are breathable, durable, and beautiful. The difference is in the finish:
Venetian plaster is often used for feature walls, ceilings, and formal spaces. Marmorino is often used for whole rooms — kitchens, bathrooms, bedrooms — where a softer, more restrained finish is desired.
We frequently install both in the same home. A common approach is Venetian plaster in the living and dining rooms, and Marmorino in the kitchen and primary suite. Read our full Marmorino vs Venetian plaster guide for a side-by-side comparison.
Miami’s climate is unforgiving to most interior finishes. Humidity, salt air, and temperature swings cause paint to peel and wallpaper to bubble. Marmorino performs differently — not because it’s tougher, but because it’s mineral-based and breathable.
Marmorino is made from lime, which is naturally breathable and alkaline. It allows moisture vapor to escape through the wall rather than trapping it inside. This is critical in Miami, where trapped moisture leads directly to mold, mildew, and structural damage.
Lime’s high pH (typically 12–13) creates an environment where mold and mildew cannot grow. This makes Marmorino an excellent choice for bathrooms, kitchens, laundry rooms, and any space with elevated humidity.
For homes in Miami Beach, Bal Harbour, Sunny Isles, and Key Biscayne, salt air is a constant threat to paint and metal finishes. Marmorino is unaffected. Lime and marble are mineral-based — they don’t react to salt. A properly sealed Marmorino wall on a coastal property will outlast multiple repaint cycles.
Marmorino’s matte finish is a natural fit for Miami’s design language:
Unlike high-gloss Venetian plaster, which makes a strong statement, Marmorino is quietly sophisticated — it enhances a space without dominating it.
Like all lime plasters, Marmorino creates a continuous, seamless surface. No grout lines. No seams. No peeling wallpaper edges. The wall becomes a single continuous plane, which is especially valuable in modern Miami interiors where clean lines are essential.
There are many contractors in Miami who claim to install Marmorino. Very few have the credentials that Exotic Wall Finishes brings.
Gian Carlo Sagasti was selected as a model for Marmorino Tools Worldwide, the Italian manufacturer of professional plastering trowels used by artisans internationally. This is not a marketing title — it reflects years of hands-on work at the highest level of the craft. His technique has been documented and used in training materials for plasterers worldwide.
In 2017, Gian Carlo was named a Novacolor Global Ambassador — a designation granted to a small number of artisans who demonstrate exceptional mastery of lime-based finishes. Novacolor is one of Italy’s most respected manufacturers of lime plasters and mineral paints.
His work has been featured in The Way Magazine (“Il re del marmorino” — “The King of Marmorino”) and on The Aggregate podcast by New Age Artisans. These features reflect a career built on craft, not advertising.
We’ve been operating in Miami-Dade, Broward, and Palm Beach counties since 2015. Over a decade of experience applying Marmorino in South Florida’s climate — not importing methods from cooler, drier regions where lime behaves differently.
We begin with a site visit or video consultation to assess:
We provide a written proposal with finish specification, timeline, and any surface preparation required.
Preparation determines the final result. We do not skip this step.
For bathrooms and kitchens, we may recommend a waterproof membrane behind the plaster.
We apply 2 to 3 base coats of lime putty, each troweled on thinly and allowed to cure. Base coats establish an even surface and provide the foundation for the pigmented layers.
This is where Marmorino’s character emerges. We apply 2 to 3 thin layers of pigmented Marmorino. Each layer is:
Unlike Venetian plaster, Marmorino is not burnished to a gloss. It’s troweled to create texture — sometimes smooth, sometimes highly tactile, depending on the design intent. Each wall is completed in one continuous session to avoid visible trowel marks.
Once the finish has cured, we apply a breathable sealer or natural wax. Sealing provides additional protection against moisture, staining, and everyday wear while preserving breathability.
We walk the project with the client, review the finish under natural and artificial light, touch up any imperfections, and provide written care instructions.
Marmorino is versatile enough for almost any interior surface.
Every project is different. We advise the best approach during consultation.

Below are recent Marmorino projects completed by Exotic Wall Finishes. Each is linked to its full case study with photos and details.
Venetian plaster is burnished to a high-gloss or satin sheen; it reflects light like polished marble. Marmorino is troweled to a matte, stone-like finish; it absorbs light. Both are lime-based, breathable, and durable. The choice depends on the aesthetic you want.
Marmorino is water-resistant but not waterproof on its own. In bathrooms, kitchens, and wet areas, we apply a breathable waterproof sealer and often a waterproof membrane behind the plaster.
With proper application and care, Marmorino can last 20 to 30 years or more, even in Miami’s humid climate. Because it’s breathable, it doesn’t peel or trap moisture the way paint does.
Yes — as long as the substrate is sound. We regularly apply Marmorino over drywall, plaster, and concrete. In some cases, over tile.
In most cases, existing paint must be removed or mechanically prepared before Marmorino is applied. Lime needs a mineral substrate to bond properly — not a plastic paint film.
Yes. Marmorino performs well on exterior walls in South Florida’s climate when properly applied and sealed. We assess each exterior project individually.
Yes. Lime’s alkaline pH (12–13) prevents mold and mildew growth. This is one of the main reasons Marmorino is favored in Miami’s humid climate.
Dust weekly with a soft cloth or microfiber duster. For marks, use a damp cloth with mild soap. Never use abrasive cleaners.
Yes. Minor scratches and scuffs can usually be touched up. Larger repairs require a skilled artisan to blend new material into the existing finish.
Pricing depends on finish, wall size, surface preparation, and accessibility. As a general reference, Marmorino typically ranges from $10 to $28+ per square foot installed. We provide project-specific quotes after consultation.
We serve Miami-Dade, Broward, and Palm Beach counties, including Coral Gables, Miami Beach, Brickell, Coconut Grove, Aventura, Boca Raton, and Palm Beach.
A typical feature wall takes 2–3 days. A full room takes 3–5 days. Larger projects take 1–2 weeks.
Yes. We work with mineral pigments and can match existing colors or develop custom shades. Sample boards are provided before installation.
If you’re ready to elevate your home or commercial space with Marmorino, we’d love to hear about your project. Every consultation is free, and every project begins with a conversation about your vision.
