Forget what you think you know about wall finishes. This isn’t just a choice between two coatings. It’s a deep decision about what your walls should be.
Modern building often seems like picking between synthetic sheens. But what if your walls could be more than just a surface? On one hand, we have cement stucco: the suburban tract-home armor. It’s a rigid, one-size-fits-all shell that keeps moisture in and beauty out.
On the other, we have the lime plaster finish: the original smart wall. It’s not just a coating; it’s a living, breathing layer. It’s the skin of a building that breathes, ages, and develops a patina of character. It’s the difference between a stiff, plastic facade and an elegant, aging partner that lives with the structure.
So, which philosophy do you want your walls to embody? A rigid, impervious shell, or a breathable, aging skin that tells a story? The choice is more than aesthetic; it’s a statement about how you think a building should live.
Villa aesthetics: depth, sheen, patina
If walls could talk, those finished in cement stucco would probably complain about their boring, uniform existence. But lime plaster? It would whisper stories in the low, warm light of a Tuscan villa, its surface alive with the subtle play of shadow and texture. This is the fundamental aesthetic divide: cement stucco is a manufactured skin, while lime plaster is a living, breathing canvas. The difference isn’t just in the mix, but in the very soul of the material.
Choosing a wall finish isn’t merely a technical decision; it’s a philosophical one. Do you want a wall that is merely a barrier, or a wall that is a participant in the life of a home? Lime plaster isn’t applied; it’s coaxed into being. Its beauty lies in its imperfections, its subtle variations, and the way it tells the story of its own creation. It doesn’t hide the hand of the artisan—it celebrates it.
The Allure of Imperfection and Luster
In a world obsessed with sterile perfection, the character of a lime plaster finish is a welcome rebellion. Its beauty is not in its flawlessness, but in its authenticity. The slight trowel marks, the gentle undulations, the way light catches on the tiniest peaks and valleys—these aren’t defects. They’re the material’s fingerprint. The sheen of a polished Venetian plaster or the soft, chalky matte of a tadelakt finish doesn’t just reflect light; it drinks it, creating a depth that paint or drywall could never achieve. It’s the difference between a mass-produced print and an original oil painting: one is a copy, the other has a soul.
This lime plaster finish offers a visual and tactile experience that changes with the time of day. Morning light skims the surface differently than the golden hour glow of dusk, revealing new depths and textures. It’s a dialogue between the wall and the world outside.
Patina as a Feature, Not a Flaw
Where modern materials fight the inevitable, lime plaster welcomes the passage of time. Cement stucco ages like a cheap t-shirt: it fades, it cracks, it stains. Lime plaster, matures. Its patina is not a flaw to be hidden, but a feature to be celebrated. As it interacts with the air and light over decades, it develops a rich, complex character that can’t be replicated. This patina is the material’s memory—a soft, velvety record of sunshine, humidity, and the gentle touch of time. It’s a wall that doesn’t just get old; it gets better.
The following table highlights the aesthetic differences that define these two materials at a glance:
| Aesthetic Property | Cement Stucco Finish | Lime Plaster Finish |
|---|---|---|
| Visual Depth | Flat, uniform, matte. Light sits on the surface. | Deep, luminous, with a sense of inner glow. Light penetrates and reflects within the micro-texture. |
| Surface Character | Consistent, often with a sprayed-on, monolithic look. Hides the hand of the artisan. | Organic, with subtle trowel marks and natural variation that reveals the craft. |
| Aging Process | Deteriorates. Cracks, stains, and efflorescence are seen as failures. | Evolves. Develops a patina; hairline cracks are often considered part of the character. |
| Interaction with Light | Reflective or absorptive, but often flat and one-dimensional. | Interactive. Creates a soft, dappled light that changes throughout the day. |
| Overall Aesthetic | Modern, uniform, controlled, and predictable. | Organic, warm, textural, and full of narrative. |
In the end, choosing a lime plaster finish is an aesthetic declaration. It’s a choice to embrace the handcrafted, the variable, and the beautifully imperfect. It’s for those who see a wall not as a barrier, but as a canvas where light, time, and craft create a living finish. It’s the difference between a wall that is simply there, and a wall that tells a story.
Building‑science basics: vapor openness, moisture buffering, salts
Forget about paint colors and trim details. The real talk about walls starts with a basic question: does your wall system breathe or suffocate? In building science, this isn’t just about looks. It’s a choice between a living wall system and a static shell.
The science of healthy walls isn’t in paint or fancy finishes. It’s in the physics of vapor, moisture, and managing them wisely.
The Wall That Breathes vs. The Wall That Suffocates
Think of your home’s walls as a second skin. Just as you wouldn’t wear a plastic bag all day, your walls shouldn’t be wrapped in a vapor-impermeable layer. This is the core of the vapor-open wall.
A vapor-open wall is like a high-performance, breathable rain jacket. It lets moisture vapor from inside your home move outward. This prevents it from getting trapped inside the wall cavity.
Cement stucco often acts like a plastic bag, locking moisture in. Lime plaster, on the other hand, is like a moisture-wicking fabric.
A wall that can’t breathe is a wall that sweats. Trapped moisture can lead to rot and mold. It can also cause paint to blister and efflorescence to bloom on the surface.
A breathable wall manages moisture dynamically. It absorbs and releases humidity to regulate indoor air quality and temperature.
The Physics of a Healthy Wall
A healthy wall is in equilibrium. Vapor-open walls manage moisture through vapor diffusion and capillary action. Lime plaster acts like a sponge and a buffer.
It absorbs moisture when the air is humid and releases it when it’s dry. This is moisture buffering, a passive solution to humidity control.
Then there’s the issue of salts. Water moving through masonry or plaster carries dissolved salts. In a closed system like a cement stucco wall, these salts get trapped and crystallize.
These salt crystals expand, creating pressure that can spall—or pop off—the finish. Lime plaster, being more vapor-open, allows these salts to migrate to the surface and be washed away by rain.
The choice of finish impacts this physics. Consider the difference:
| Feature | Lime Plaster | Cement Stucco |
|---|---|---|
| Vapor Permeability | High. Allows moisture vapor to pass through easily. | Very Low. Acts as a vapor barrier, trapping moisture. |
| Moisture Buffering | Excellent. Absorbs and releases moisture, regulating humidity. | Poor. Cannot absorb moisture; moisture is trapped or shed only. |
| Salt & Efflorescence | Allows salts to migrate and wash away; self-cleans. | Traps salts, leading to spalling and surface damage. |
| Impact on Wall Assembly | Protects the structure by allowing it to “breathe out.” | Can trap moisture against sheathing, risking rot and mold. |
| Longevity Driver | Flexible and self-healing; moves with the building. | Rigid and brittle; prone to cracking and water intrusion. |
Choosing a finish isn’t just about looks. It’s a fundamental decision about how your building manages water and vapor. Vapor-open walls aren’t just a “green” trend. They’re a return to a more intelligent, dynamic, and forgiving way of building that has worked for centuries.
Where each shines: interiors, exteriors, coastal facades, baths
Choosing between lime plaster and cement stucco is more than just about looks. It’s about the life of your building. The right choice depends on the specific needs of your project.
Matching the Material to the Mission
Wearing wool to the beach or swim trunks to a meeting doesn’t make sense. The same goes for your walls. The best material is the one that wins in its environment.
Cement stucco is great for dry, stable places like the American Southwest. But in wet, changing environments, it’s not as good. Its rigidity can be a problem.
Lime’s Niche: The Demanding Environments
Lime plaster is a top choice for tough environments. It’s special because it lets moisture pass through. This is key to its durability.
Think of a coastal home’s salt-lashed facade. Cement stucco holds salt and moisture, causing damage. But lime plaster lets salt crystals escape with rain, keeping the structure strong.
- Historic & Heritage Buildings: Lime is essential for old buildings. It lets them breathe and prevents moisture damage.
- High-Humidity Interiors (Bathrooms, Kitchens, Spas): Lime keeps moisture from getting trapped, stopping mold and mildew. Cement can trap moisture, leading to mold.
- Regions with Freeze-Thaw Cycles: Lime flexes with ice and building movements without cracking. Cement stucco is more likely to crack.
In short, cement stucco is a solid barrier. Lime plaster is a living system. For coastal facades, steamy bathrooms, or old cottages, lime’s ability to breathe is its main strength. It’s designed to last in tough conditions.
Substrates and prep: masonry, sheathing, lath, base coats
Forget the topcoat for a moment. The real magic of lime plaster or cement stucco lies in the hidden layers. It’s the foundation of a masterpiece or the start of a costly failure. A good substrate is key to a lasting finish.
True craftsmanship is shown in the prep work, not just the finish. A good substrate is essential for a finish that lasts. Plaster is more than a surface; it’s a system.
The Canvas Matters as Much as the Paint
Imagine painting oil on a wet, rotting board. It won’t work. Walls need a compatible substrate for plaster. The goal is a sympathetic, stable substrate that ages well with the finish.
Lime plaster and cement stucco have different needs. Lime wants a flexible partner, while cement stucco needs something rigid.
A Foundation of Compatibility
The base coats are often overlooked but critical. They ensure the topcoat and substrate work together. Choosing the right base coat is key:
- For Lime Plaster: A lime plaster base coat works well on solid masonry. It’s a match made in mineral heaven.
- For Cement Stucco: A scratch and brown coat is used on modern sheathing. It needs a metal lath for a strong bond.
Moisture management is key. Lime plaster absorbs and releases vapor. Its substrate must be breathable. A masonry substrate is ideal. On wood or metal, a vapor-open, self-furring metal lath is needed.
Cement stucco needs a weather-resistive barrier and drainage plane. Its prep is about sealing. Lime plaster prep focuses on breathability.
The prep work is essential. It makes the difference between a lasting finish and a maintenance problem. The canvas is a silent co-author of the final work.
Application and textures: smooth, marmorino, tadelakt, sand finish
Think of the wall as a canvas and the application technique as the brushstroke. Plaster goes beyond a simple wall covering, becoming an artisanal craft. Unlike cement stucco, lime plaster offers a range of textures. It’s like the difference between a mass-produced print and a hand-painted canvas.
This isn’t just about getting mud on a wall. It’s about creating a surface with character, depth, and a story.
From Polished Marble to Rustic Stucco
Choosing a finish is like casting an actor for a role. The right texture sets the mood of the space. You wouldn’t cast a gritty actor in a polished aristocrat role. Each plaster finish has its own role.
The Artisan’s Toolbox
The artisan’s toolbox for lime plaster is varied. It’s not just about the trowel, but the hand that guides it. Here’s a breakdown of essential tools and materials:
- Batching Buckets & Mixing Paddles: Lime putty, marble dust, and water are blended to a specific consistency, the foundation of any good plaster.
- Hawk and Trowel: The primary tools. The hawk holds the plaster, while the trowel applies it. The pressure, angle, and motion of the trowel create the texture.
- Floats and Trowels: From stainless steel for a glass-smooth finish to wood or plastic floats for a more textured, “skip-trowel” effect.
- Brushes and Sponges: For applying thin, translucent layers of Venetian plaster or for creating specific textures like a spatolato or stucco veneziano finish.
- Burnishers and Polishers: Smooth stones, trowels, or specialized burnishing tools are used to compact and polish the surface to a sheen, essential for finishes like Venetian plaster and tadelakt.
Consider the following common finishes, from the most refined to the most rustic:
| Finish | Primary Tools | Key Characteristic | Best For |
|---|---|---|---|
| Venetian Plaster (Marmorino) | Stainless steel trowel, burnishing stone | Polished, marble-like sheen with depth | Feature walls, high-end interiors, areas of reflection |
| Tadelakt | Special soap, polishing stones | Water-resistant, high-gloss, seamless | Bathrooms, showers, wet rooms |
| Marmorino | Specialty trowels, trowel burnisher | Polished aggregate, pearlescent sheen | Historical restorations, elegant interiors |
| Sand/Stucco Finish | Float, trowel, sponge | Textured, matte, highly tactile | Exteriors, rustic or Mediterranean styles |
The Smooth Operator: Polished Plaster
Think of a polished Venetian plaster finish as a bespoke suit. It’s not just smooth; it’s a deep, luminous finish. The result isn’t a flat paint job—it’s a surface that breathes and changes with the light.
This is the Venetian plaster you see in high-end galleries and luxury hotels, a finish that whispers sophistication.
The Rustic Charm of Sand Finishes
On the other end of the spectrum lies the textured, sandy finish of a lime stucco. This is the finish that whispers, not whispers. It’s tactile, with a grain and body that cast soft shadows.
It’s the architectural equivalent of a well-worn leather jacket—it looks better with age and tells a story. This is the finish for a home that wants to feel grounded, organic, and connected to the earth.
The Specialists: Marmorino and Tadelakt
Marmorino is the refined cousin of Venetian plaster, often with a more pronounced aggregate for a “crushed marble” effect. Tadelakt, the star of Moroccan hammams, is a lime plaster that is polished with a special soap, creating a water-impermeable, glass-like surface.
It’s not just a finish; it’s a waterproof skin, perfect for creating seamless, monolithic showers that feel like sculpture.
In the end, the choice of texture is a declaration. Do you want the quiet luxury of polished Venetian plaster or the raw, earthy honesty of a sandy finish? With lime plaster, the wall is no longer a boundary. It’s a statement.
Durability: hairline cracks, repairs, sealing, maintenance cycles
Building materials face a real test over time, not just at first glance. Cement stucco and lime plaster show two different ways to handle this. One is about being perfect and rigid, while the other is about being flexible and adaptable.
Think of your walls as a partner in your home’s life, not just a static backdrop. Their durability isn’t about being a static, unchanging monolith. It’s about resilience, repairability, and the story that time inscribes on a surface.
The Living Finish and Its Care
Lime plaster is a living finish. It breathes, it flexes, and it has a memory. A hairline crack in lime plaster is not a failure; it’s a sign of settling into its environment.
Caring for a lime plaster wall isn’t about preventing the inevitable; it’s about working with it. The maintenance cycle is not a cycle of destruction and replacement, but of gentle, localized intervention. You’re not a slave to a 10-year re-stucco schedule. Instead, you engage in a kind of stewardship.
The Self-Healing Myth and the Art of the Patch
Lime plaster does not magically knit itself back together like skin. The “self-healing” quality is a slight misnomer, but the reality is more empowering. While it won’t close a crack on its own, it allows for a seamless repair that is the stuff of cement stucco’s dreams.
Here’s the key difference, laid bare:
| Maintenance Factor | Lime Plaster | Cement Stucco |
|---|---|---|
| Hairline Crack Response | Natural, expected movement. Often stable and can be left or easily filled. | Sign of failure in the monolithic barrier; often widens and leads to water intrusion. |
| Repair Philosophy | Localized, sympathetic repair. New lime plaster fuses with the old on a chemical level. The patch becomes the wall. | Patchwork repair is often visible (“ghosting”). The new cement doesn’t bond the same, leading to a “band-aid” effect. |
| Breathability & Damage | Allows vapor to pass. Moisture behind the wall can escape, preventing trapped moisture and freeze-thaw damage. | Vapor-closed system. Trapped moisture behind the stucco can’t escape, leading to hidden rot, mold, and structural spalling. |
| Long-Term Maintenance Cycle | Century+ lifespan with spot repairs. Maintenance is a craft, not a demolition. | 15-30 year lifecycle with a large-scale, costly full replacement. |
When a crack repair is needed in lime plaster, it’s a craft, not a cover-up. A skilled artisan doesn’t just fill a gap; they create a new lime putty patch that cures and ages in harmony with the surrounding historic fabric. It’s the difference between a plastic surgeon and a tailor—one tries to mask, the other weaves new material into the old with invisible seams.
The so-called “self-healing” is really a property of breathability and flexibility. Lime’s vapor-open nature means that when small cracks do form, they don’t become moisture traps. The material “gives” a little, preventing the crack from propagating the way it would in a rigid, brittle cement matrix. The maintenance cycle isn’t about constant crack repair but about understanding and working with the material’s nature.
In the end, the durability of your finish isn’t just about withstanding the first blow, but how gracefully it ages and how elegantly it can be healed. Lime plaster doesn’t hide from time; it incorporates it into its character, making maintenance a dialogue with history, not a war against it.
Cost and schedule: skilled labor, cure times, DIY feasibility
Let’s talk about the real cost of a wall. It’s not just the contractor’s quote. It’s about the craft, schedule, and the story it will tell for years to come. Choosing between lime plaster and cement stucco is a financial and philosophical decision. Are you buying a commodity or investing in a legacy?
The Investment in Time and Craft
The truth is, the bag of lime or cement powder is the cheapest part. The real investment is in the skilled plasterer whose trowel is an instrument. This is where the ledger diverges dramatically.
Cement stucco is like fast food: mass-produced, uniform, and applied quickly. A crew can cover a modern home in a day or two. It’s the cost-effective, no-surprises option.
Lime plaster is like slow food, farm-to-table. It requires patience. It demands an artisan who understands its temperamental nature—the slow cure time, the carbonation process, and the application of multiple, thin coats over days or weeks. You are paying for the concerto, not just the sheet music. This skilled labor is the primary cost driver, making the upfront price per square foot for lime plaster cost significantly higher in the short term.
The schedule tells a similar story. A cement stucco job might be a “rinse and repeat” process over a long weekend. A traditional lime plaster application, with its necessary cure times between coats, can stretch over weeks. This isn’t a flaw; it’s a feature. The material demands respect for its natural process.
The True Cost of a Timeless Finish
This is where the ledger flips. The initial cement stucco price is a siren song. The true cost of a timeless finish is measured in decades, not just the first-year maintenance budget.
Consider the long-term ledger. A lime plaster wall is a living, breathing system. A tiny crack in a lime plaster wall can often “self-heal” as free lime in the wall reacts with carbon dioxide to form new calcite. Its vapor permeability means moisture that gets in can get out, preventing the catastrophic, hidden rot that can lurk behind a failed cementitious barrier. A cement stucco wall, while a tough shell, is unforgiving. When it cracks—and it will—it stays cracked, and moisture can become trapped, leading to potentially catastrophic and expensive repairs.
Here’s a breakdown of where your money and time actually go:
| Factor | Traditional Lime Plaster | Modern Cement Stucco |
|---|---|---|
| Material Cost (per sq. ft.) | Moderate | Low |
| Labor & Skill Level | High (Specialized Artisan) | Moderate (Trained Crew) |
| Application & Cure Time | Weeks (slow, multi-coat cure) | Days (fast-setting) |
| Primary Cost Driver | Skilled Craftsmanship | Material Volume & Speed |
| Long-Term Value | High (Self-healing, durable, ages gracefully) | Moderate (Prone to aesthetic and moisture-related failures) |
DIY Feasibility? Forget it with lime. It’s not a DIY lime plaster weekend project. Cement stucco is more forgiving for a brave amateur, but the risk of a botched, non-breathable wall is high. For lime, the skilled plasterer isn’t a luxury; they are the entire point.
So, the final analysis isn’t just about the line item for labor and materials. It’s about the total cost of ownership. You’re not just buying a wall covering. With cement stucco, you’re buying a product. With lime plaster, you’re commissioning a performance—an artisan plaster system that carbonates, self-heals microcracks, and matures over decades. For a broader cost comparison and specification breakdown, see our guide on Lime Plaster vs. Cement Stucco: Cost, Maintenance, and Longevity
From a building science standpoint, lime’s vapor permeability and ability to reabsorb CO₂ during carbonation are well documented by organizations such as Historic England, which highlights lime’s role in maintaining breathable, moisture-balanced historic fabric. The schedule is longer, and the upfront lime plaster cost is higher, but the lifecycle performance—reduced trapped moisture, lower long-term repair frequency, and material reversibility—often justifies the premium.
Color strategies: mineral pigments, limewash, aging gracefully
Forget paint. The talk about wall color can go deeper. Lime plaster and limewash offer a dynamic finish where color is embedded. This is where color isn’t just a topcoat but a mix of pigment and plaster.
This approach isn’t about a single color. It’s about a process and a material that will change over time. It tells a story for decades.
Color That Lives in the Wall, Not On It
This is a big difference from usual finishes. With lime plaster, color is part of the wall’s fabric. It’s like a tattoo, not a costume.
Mineral pigments are mixed into the plaster or limewash. So, the color you see is the material itself, not just a layer. This is why it won’t chip or peel like paint.
The color is the wall. This means the finish and its hue are one with the substrate. It creates a surface that ages as a single entity.
The Alchemy of Mineral Pigments
Forget the Pantone book. The palette for lime-based finishes comes from the earth. The mineral pigments used are natural and have a unique character.
Unlike synthetic dyes, these pigments are stable and lightfast. They are also vapor-permeable. This means they don’t just sit on the surface but are part of the lime itself.
This is the “alchemy.” The color you apply will change over time. It will mellow and deepen in a way synthetic paints can’t.
This approach is more than just aesthetics. It’s about material honesty. The natural pigments and lime binder work together, allowing the wall to breathe.
The color you choose for your lime plaster or limewash is just the beginning. It’s the start of a long conversation with light, air, and time.
| Color Strategy | Lime Plaster & Limewash | Painted Cement Stucco or Drywall |
|---|---|---|
| Color Integration | Pigments are integral to the plaster or wash; color is the material. | Color is a superficial film of paint applied to the surface. |
| Aging Process | Ages gracefully, developing a patina; color mellows and deepens. | Degrades; paint fades, chalks, peels, and requires full repainting. |
| Breathability | Vapor-open; color layer is also vapor-permeable. | Paint film can trap moisture, potentially causing blisters or mold behind the film. |
| Maintenance Cycle | Limewash may need reapplication every 5-10 years; a lime plaster wall is effectively permanent. | Repainting typically required every 5-7 years for exterior, less for interior. |
| Aesthetic Outcome | Deep, complex, matte finish that ages gracefully with a unique patina. | Uniform, flat color that shows wear, scuffs, and a “manufactured” look over time. |
The aging process is a feature, not a bug. A limewash is designed to wear. It will fade in a soft, gradient way, which is part of its charm.
This natural decay is part of its beauty and function. It’s a finish with a life cycle, not a product with a warranty.
Choosing a color strategy for lime is less about picking a swatch. It’s more about choosing a partner for the next 20 years. It’s a decision to embrace a material that is alive and tells a story in your walls.
Buying/contractor checklist
Finding the right artisan for your lime plaster project is more than just hiring a contractor. It’s about finding someone who truly understands and values this ancient craft. You need a specialist, not just anyone who dabbles. Your checklist is a way to protect yourself from making a bad choice.
Vetting the Artisan, Not Just the Estimate
Don’t just look for the lowest bid. In lime plaster work, you’re investing in a lime plaster artisan, not just a service. The cheapest option often means shortcuts and lack of experience. Look at their portfolio first. A true lime plaster contractor will have lots of lime-specific projects to show.
Ask to see their portfolio. If most of their work is stucco or quick spray jobs, they’re not right for you.
Questions to Ask, Red Flags to Spot
This is your chance to really understand who you’re hiring. You want to find the true craftspeople and avoid the fake ones. Be ready with these questions and know what to watch out for.
- The Portfolio Interrogation: Look at the pictures, but ask more. “What was your mix for this project?” If they can’t talk about the lime putty, aggregate, or cure time, they’re not genuine. A true lime plaster artisan will discuss these details with passion.
- The Mix Matters: Ask directly: “Do you mix your own lime putty?” The answer is key. A true artisan will make their own, while a shortcut artist uses pre-mix. They should be excited to talk about the putty.
- The Reference Check: Ask for references for lime projects. A great stucco contractor isn’t always a great lime plasterer. Call the references and ask about their experience with lime’s unique needs.
- The Red Flag Roundup:
- The Hybrid Hustle: If they suggest adding Portland cement to lime for strength, run. This is a big mistake. It sacrifices the breathability you’re paying for.
- The Vague Portfolio: “We do all kinds of plaster.” This means they’re not experts in lime plaster. You need someone who specializes.
- Speed Demons: Lime plaster work is slow and careful. If they promise to do it fast, they’re not taking the time needed. Lime needs patience for proper curing.
- No Talk of Vapor Permeability: If they don’t understand why breathability is important, they don’t get the material. This is a big red flag.
Your lime plaster checklist is your first defense. It shows you respect the craft. You’re not just hiring a lime plaster contractor; you’re choosing a caretaker for your home. The right artisan will appreciate your attention to detail.
Conclusion
So, where does this journey end? Choosing between lime plaster and cement stucco isn’t just a simple decision. It’s about what you value more: character versus convenience.
Cement stucco is the practical choice. It’s efficient and easy to maintain. It lasts for 50 years with little effort. A professional plastering resource shows it’s durable and efficient. It’s like a reliable car that always gets you where you need to go.
Lime plaster is different. It’s for those who value craftsmanship. It requires more money and patience. But it offers a wall that changes and tells a story. It’s alive and works with nature.
Ultimately, you’re not just picking a wall finish. You’re choosing a partner for your home’s future. Do you want the easy, dependable cement stucco or the unique, living lime plaster? The wall you choose starts your home’s next chapter.
