Lime paint is a mineral-based wall finish made from hydrated lime, natural pigments, and water. Unlike conventional paint, which forms a plastic film on the surface, lime paint soaks into the wall and crystallizes — becoming part of the wall itself. When it cures, it reacts with carbon dioxide in the air and hardens into a durable, breathable surface.
In Miami, lime paint has become a preferred finish for homeowners, designers, and architects who want the beauty of traditional paint with the performance of a mineral finish. It’s breathable, mold-resistant, and doesn’t peel. It performs where conventional paint fails.
Exotic Wall Finishes has been applying lime finishes in Miami since 2015. Our founder, Gian Carlo Sagasti, is a Novacolor Global Ambassador (2017) and has been working with lime-based materials since 2003.
Lime paint is made from hydrated lime (calcium hydroxide), water, and natural mineral pigments. It’s similar to lime wash but thicker and more opaque — creating a more uniform finish with fuller coverage.
When lime paint is applied to a mineral surface (plaster, masonry, brick, stone, or previously lime-treated walls), it penetrates the surface and reacts with carbon dioxide in the air through carbonation. Over days and weeks, it converts back into calcium carbonate — essentially turning back into limestone. This is why lime paint hardens over time and lasts.
Both are mineral-based and breathable. The choice depends on the effect you want.
For Miami’s climate, lime paint is the more durable long-term choice.
Miami’s humidity is one of the toughest environments in the country for interior and exterior finishes. Lime paint performs where conventional paint fails.
Lime paint allows moisture vapor to pass through the wall rather than trapping it. This is critical in Miami, where trapped moisture leads to mold, mildew, and structural damage. Conventional paint traps moisture against drywall — the perfect environment for mold.
Lime paint is alkaline (pH 12–13), which prevents mold and mildew from growing. In bathrooms, kitchens, laundry rooms, and coastal properties, lime paint resists the biological growth that plagues painted surfaces.
For homes in Miami Beach, Bal Harbour, Key Biscayne, and Sunny Isles, salt air damages conventional paint. Lime paint is unaffected. Mineral-based finishes don’t react to salt.
Miami has a rich stock of historic homes — particularly in Coral Gables, Coconut Grove, and the Roads — many of which were originally finished with lime-based products. Lime paint is the historically appropriate choice for these homes.
Lime paint performs exceptionally well on exterior masonry, stucco, and brick in South Florida. Its breathability allows walls to dry out after storms, and its alkaline pH resists mold.
Lime paint has been used in Europe for centuries. Its soft, matte appearance is unlike any conventional paint. It’s used in:
Gian Carlo Sagasti was named a Novacolor Global Ambassador in 2017 — a designation granted to a small number of artisans worldwide. Novacolor is one of Italy’s leading manufacturers of lime plasters and mineral paints.
Gian Carlo has been working with lime finishes since 2003 — over 20 years of hands-on experience with lime-based materials.
We’ve been operating in Miami-Dade, Broward, and Palm Beach counties since 2015. A decade of applying lime paint in South Florida’s specific climate.
Every project begins with a site visit. We assess:
Lime paint cannot be applied over most paints because it needs to soak into a mineral surface. We assess and advise during consultation.
Lime paint is applied in 2 to 3 coats, depending on the desired opacity. Each coat is applied by brush, roller, or spray and worked in for an even finish. Between coats, the surface is allowed to dry but not fully cure.
For interior applications, we often finish with a natural wax or breathable sealer. For exterior applications, we use a breathable mineral sealer.
We walk the project with the client, review the finish under natural and artificial light, and provide written care instructions.

Recent lime paint projects completed by Exotic Wall Finishes.
No. Lime paint is breathable and water-resistant but not waterproof. In bathrooms, kitchens, and exteriors, we apply a breathable mineral sealer.
Interior lime paint lasts 5 to 10 years before needing a refresh. Exterior lime paint in Miami’s climate typically lasts 5 to 7 years.
No. Lime paint doesn’t peel because it doesn’t form a film. It calcifies into the surface.
Lime paint is thicker and more opaque. Lime wash is thinner and more translucent. Both are mineral-based and breathable.
In most cases, no. Lime paint needs to soak into a mineral surface. If the wall is painted, the paint must be removed or the surface re-prepared.
Yes — with a breathable sealer. Lime paint is naturally mold-resistant due to its alkaline pH.
Yes, and it’s one of the best choices for Miami’s climate.
Yes. Lime paint is mineral-based, contains no VOCs, and has a low environmental impact.
Dust with a soft cloth. For marks, use a damp cloth with mild soap. Avoid abrasive cleaners.
Yes. Damaged areas can usually be blended with additional coats.
Pricing depends on surface, size, and preparation. As a general reference, lime paint typically ranges from $5 to $14 per square foot installed.
We serve Miami-Dade, Broward, and Palm Beach counties.
A typical room takes 2–3 days. Exterior projects depend on size and prep.
Yes. We work with mineral pigments and can match existing colors or develop custom shades.
