Limewash paint is a water-based, mineral wall finish made from slaked lime (calcium hydroxide), natural pigments, and — in premium Italian formulations like those from San Marco — carefully engineered mineral binders that improve workability, depth, and longevity.

Unlike standard latex or acrylic wall paint — which sits on the surface of drywall or plaster as a sealed film — limewash penetrates the substrate, bonding chemically through a process called carbonation. The result is a finish with translucent, layered depth that shifts subtly with the light throughout the day. Interior designers call this quality 'movement,' and it is impossible to achieve with flat paint.

Limewash has been used for centuries across Italy, Morocco, Greece, and throughout the Mediterranean world. What changed between 2023 and 2026 is the technology behind it. Modern Italian mineral plasters from San Marco — available in the US through The Decora Company — combine ancient lime chemistry with contemporary engineering: consistent application behavior, extended open working time, a broad custom color palette, and real performance on real American walls.

American homeowners in 2026 are primarily drawn to limewash for three reasons: it creates a wall that looks expensive and designed without a full renovation; it solves the problem of flat, builder-grade paint that makes every room look the same; and it photographs beautifully in every light condition — a quality that has become a genuine priority for how people think about their living spaces.

The bottom line: if you want your living room feature wall to stop looking like every other painted wall in America, San Marco limewash and decorative plasters — available now at thedecoracompany.com — are the answer.

Section 1: What Limewash Paint Actually Is

The chemistry — why it looks different from paint

Limewash begins with calcium hydroxide — slaked lime — produced by burning limestone and combining the resulting calcium oxide with water. This creates a highly alkaline, naturally antimicrobial mineral liquid. When combined with natural mineral pigments and the polymer binders used in premium Italian formulations, it becomes a workable decorative finish for interior and exterior walls.

The defining chemical reaction is carbonation. When wet limewash contacts the wall and begins to dry, it reacts with atmospheric carbon dioxide and slowly converts back into calcium carbonate — the same mineral that limestone is made from. This is why limewash bonds structurally with the plaster or drywall beneath it rather than forming a surface film on top. It does not peel the way paint peels. It does not chip the way paint chips. It ages, and in most cases it gets better-looking as it does.

 

▌

Why this matters for your walls Because limewash bonds chemically to the substrate rather than coating it, moisture vapor can pass through the wall rather than being trapped behind a sealed film. This breathability is why mineral finishes consistently outperform latex paint in spaces where humidity varies — kitchens, entryways, spaces with fluctuating heat and A/C.

 

The history: from Italian villas to American living rooms

Limewash is one of the oldest wall finishes on earth. Archaeological evidence of lime-based finishes dates back over 10,000 years. Across the Mediterranean — Italian palazzos, Greek island homes, Moroccan riads, Spanish farmhouses — lime plaster was the dominant interior finish for most of recorded history. It was not simply paint. It was a craft.

San Marco, founded in Italy over 80 years ago, emerged from this tradition. Their decorative plaster line — Marmorino, Concrete Art, and their full range of mineral finishes — represents the modernization of centuries of Italian lime craftsmanship. The formulas use the same fundamental chemistry as historic lime finishes, but with mineral engineering that makes the products consistent, controllable, and applicable in a wide range of conditions.

The Decora Company brings these products directly to American homeowners and professionals. No intermediary markup. No guessing what a European product will do on American drywall. The team has spent over a decade applying, testing, and teaching these finishes in the US market specifically.

What does a limewash wall actually look like?

The closest honest description: a limewashed wall looks like color lives inside the wall, not on top of it. The tone shifts subtly as you move across the surface. There are lighter passages and deeper passages. At certain angles in certain light — especially in the afternoon when sun rakes across the wall at a low angle — the surface appears almost stone-like, as if it was part of a centuries-old building rather than a renovated American home.

This quality is impossible to capture adequately in photographs, which is both limewash's challenge (getting people to understand it before they see it in person) and its advantage (rooms with limewash feature walls consistently look better in person than they do in photos, which is the opposite of most interior finishes).
Section 2: Why Limewash Became Mainstream in 2026

American interiors hit a wall with flat paint

The dominant residential aesthetic of the 2010s was minimalism — white walls, clean lines, Scandinavian-influenced simplicity. It produced beautiful spaces. Repeated across millions of American homes with the same flat white latex paint from the same big-box stores, it also produced something else: visual uniformity so complete that rooms became indistinguishable from each other.

By 2023, the data from design platforms made the direction of change clear. Searches for textured walls, limewash, Venetian plaster, and decorative plaster were growing at rates that signaled not a passing trend but a genuine aesthetic correction. By 2026, that correction has matured into mainstream demand. Homeowners are not asking 'how do I make my walls clean?' They are asking 'how do I make my walls interesting?' San Marco decorative finishes, available through The Decora Company, are the most credible answer to that question.

The content and design media effect

Interior design content — across YouTube, Instagram, Pinterest, and design publications — is overwhelmingly shot against limewashed or textured plaster backgrounds. This is not coincidence. Limewash walls provide a background that is visually rich without competing with the subject: the furniture arrangement, the lifestyle scene, the people. The tonal variation catches light in a way that flat paint cannot, and that difference is visible in every format.

As interior creators and design accounts began shooting consistently against mineral plaster backgrounds, a new consumer demand formed: homeowners who wanted their spaces to look the way the spaces they admired looked. Limewash was the common denominator. The Decora Company has seen this drive its own growth — customers arriving with a screenshot of a room they want to recreate, asking what product was used.

Builder-grade paint is the wrong product for living rooms

Here is an observation that is rarely stated directly in the decorative finishes industry: standard flat latex paint is a utility product. It is designed for speed, coverage, and price. It is the right product for ceilings, utility rooms, and spaces where appearance is a secondary concern. It is the wrong product for a living room feature wall where appearance is the entire point.

The design industry has always known this. What has changed is that American homeowners now know it too — and they are acting on it. San Marco's range of decorative plasters and limewash finishes fills the gap between 'I want something better than flat paint' and 'I need to do a full renovation.' That gap, in 2026, represents exactly where millions of US homeowners currently are Section 3: San Marco by The Decora Company — Who You Are Buying From

San Marco: 80+ years of Italian decorative finish engineering

San Marco is an Italian manufacturer with over eighty years of history in professional decorative paints, mineral plasters, and wall coatings. Their product development is rooted in the Italian tradition of decorative finishing — a discipline that treats wall surfaces as part of the architectural design, not merely as a base coat for furniture.

The San Marco product range covers the full spectrum of decorative finishes: from classic Marmorino lime polished plaster in the classic tradition, to contemporary concrete-effect finishes, metallic decorative paints, and specialty coatings for floors and exterior applications. Their color system — organized around four mood collections (Energy, Minimal, Soft, and Black & White) — is designed by Italian color specialists and regularly updated to reflect contemporary design direction.

The Decora Company: San Marco's US retail partner

The Decora Company (thedecoracompany.com) is a US-based specialist retailer that has carried San Marco products for over ten years. They are not a general paint store that happens to stock a few Italian products. Their entire catalog is built around San Marco decorative finishes and the professional tools — Pennelli Tigre brushes, specialist trowels, spatulas — needed to apply them correctly.

What this means for you as a buyer: you are purchasing from a team that has applied these products themselves, taught application classes to both DIY homeowners and professional decorators, and built a decade of US-specific knowledge about how San Marco finishes perform on American drywall, in American climates, over American paint and primer systems.

▌	Free shipping threshold The Decora Company offers free shipping on all orders over $395 across the United States. For most feature wall projects requiring product plus primer, this threshold is easy to reach. Call (608) 620-5066 or visit thedecoracompany.com to discuss your project before ordering.

 

Section 4: The San Marco Decorative Plaster Range — What Is Available

Understanding which San Marco product is right for your project requires knowing what each product is designed to do. The Decora Company carries the core San Marco decorative plaster and paint range. Here is a structured guide to the main product categories.

Marmorino Classico — Decorative Lime Polished Plaster

Marmorino is San Marco's classic decorative lime polished plaster, finished to a satin sheen. This is the traditional Italian plaster finish — derived from marble dust and lime — that has been used in Italian interiors for centuries. Applied and burnished with a steel trowel, it creates a surface that resembles polished stone: smooth, reflective at certain angles, and extraordinarily deep in its visual quality.

Marmorino is the choice for homeowners and designers who want a finish that reads as genuinely luxurious rather than textured. It requires a higher level of application skill than brushed limewash — the burnishing technique determines the quality of the final finish — but The Decora Company's in-person classes teach this technique, and detailed application guides are available on both the San Marco and Decora Company websites.

•       Finish type: Satin polished, stone-like depth

•       Application: Steel trowel, burnished while setting

•       Best for: Living rooms, dining rooms, hallways, feature walls in new construction

•       Skill level: Intermediate to advanced; classes recommended

 

Concrete Art — Faux Concrete Decorative Plaster

Concrete Art is San Marco's faux concrete finish — a fine-grain mineral plaster that replicates the look of polished industrial concrete without the weight, cost, or permanence of actual concrete. It produces a smooth, matte surface with the subtle variation in tone that characterizes real concrete: slightly lighter here, marginally darker there, with no two sections looking precisely identical.

This finish has been one of The Decora Company's best sellers for several years, driven by the consistent demand for industrial-contemporary aesthetics in American kitchens, open-plan living spaces, and commercial interiors. It is more forgiving in application than Marmorino — the texture absorbs minor imperfections — and is available in a wide color range that extends well beyond the standard grey-concrete palette.

•       Finish type: Matte, fine-grain concrete texture

•       Application: Trowel or spatula, two to three layers

•       Best for: Kitchen feature walls, open-plan living, commercial spaces, bathrooms

•       Skill level: Intermediate; first-time applicators should practice on board

 

Marcopolo Luxury — Metallic Decorative Paint

Marcopolo Luxury is San Marco's metallic decorative paint — a product in a different category from plasters, but equally distinctive in its effect. Applied with a brush or pad, it creates a surface with a subtle metallic shimmer and a fine sand-grain texture that catches light differently across the wall. The effect ranges from a gentle pearlescent quality in lighter colors to a bold metallic statement in deeper tones.

This product is particularly effective as an accent — applied to one wall in a room, or to architectural features like alcoves, chimney breasts, or ceiling coffers. It is one of the more accessible San Marco products for DIY application and produces a result that is immediately dramatic without the technical demands of polished plaster.

•       Finish type: Metallic shimmer with subtle sand texture

•       Application: Brush or applicator pad

•       Best for: Accent walls, architectural features, bedroom headwall, powder rooms

•       Skill level: Beginner to intermediate

 

Patina Wax — Professional Plaster Finishing Wax

Patina Wax is not a decorative finish in itself — it is a professional clear wax applied over Marmorino and other polished plasters to seal, protect, and enhance the finished surface. It brings out the depth of polished plaster, adds a slight sheen, and protects the surface from minor abrasion and moisture contact. In certain spaces — hallways, areas near sinks — a wax topcoat is recommended for longevity.

 

Primers and preparation products

San Marco's primer range — including the Marcotherm Primer (a sealer/primer with quartz sand grains) available at The Decora Company — is an essential part of achieving a professional result. Applying a San Marco decorative plaster over an incompatible primer is one of the most common causes of adhesion failure and uneven color absorption. The Decora Company product pages specify which primer is recommended for each finish and substrate.

Section 5: Full Comparison — San Marco Limewash vs Other Decorative Finishes

Before committing to any decorative wall finish, understanding how the options compare is essential. The table below covers the four finishes that American homeowners most commonly consider when upgrading a living room feature wall.

Detailed verdict: finish by finish

San Marco limewash and mineral plasters — the recommended choice

For an American DIY homeowner looking to transform a living room feature wall — one that has builder-grade paint, some settlement cracks, or simply looks flat and lifeless — San Marco decorative plasters are the right category of product. They are designed to perform on real walls in real conditions. They are engineered to forgive the imperfections that American drywall construction produces. And they create a result that, once done, looks like it cost a great deal more than it did.

The Decora Company carries the full range, ships across the US, and provides class-based training for applicators who want to learn the technique before committing to a full project. Free shipping applies on orders over $395.

Venetian plaster — spectacular but unforgiving

Venetian plaster produces an extraordinary result: a polished, stone-like surface with depth and luminosity that is genuinely architectural. But it requires a near-perfect substrate. Any crack, any unevenness in the drywall or plaster beneath, any inconsistency in the taping and mudding of a drywall surface — all of these will be amplified by Venetian plaster rather than absorbed. For most existing American homes with their real-world wall history, Venetian plaster either requires significant prep work or should be applied by an experienced professional who can manage those variables. The Decora Company carries Marmorino Classico for those pursuing this finish.

Microcement — excellent in the right application

Microcement is a thin-coat cement-based finish that produces a smooth, contemporary, industrial look. It performs exceptionally well in wet areas — bathrooms, laundry rooms, kitchen splashbacks — and on floors. The application technique is technically demanding: multiple thin coats, precise timing, sealing. For a living room feature wall where the goal is warmth, depth, and visual richness, microcement tends to read as cold and industrial. It is the right product in the right application; the living room feature wall is rarely that application.

Flat latex/emulsion paint — the wrong tool

Standard flat latex paint is a utility product designed for coverage, speed, and economy. It is appropriate for ceilings, utility spaces, and rentals where repainting every three to five years is acceptable. On a living room feature wall where the goal is visual character and longevity, it is simply the wrong choice. It reveals every drywall imperfection. It has no depth. It does not age gracefully. And the cost of repainting it every few years, over a decade, exceeds the one-time cost of a mineral plaster finish that lasts fifteen years and looks better over time.

Section 6: A Real Living Room Transformation — US Client Story

The following describes a real project completed with San Marco product sourced through The Decora Company. Details are generalized at the client's request, but the wall conditions, product choices, and outcome are accurate.

The starting point

The client had a standard American suburban living room — 12 feet by 15 feet, drywall construction, 9-foot ceilings. The feature wall behind the sofa had been painted the same builder-grade flat white as the rest of the house at some point in the prior decade. The wall showed three clear problems: a horizontal line where two different batches of the same paint had been applied at different times, creating a barely perceptible but persistent color shift; a corner section where the drywall tape had started to show through the paint as a faint ridge; and a general flatness and lifelessness that made the room feel unfinished despite containing good furniture and good design choices everywhere else.

The client had looked at wallpaper (too permanent, too risky for a rental-sensitive market), shiplap (too trendy, too commitment-heavy), and dark paint (too dramatic for the light levels in the room). They arrived at The Decora Company through an online search and, after reviewing the product range, chose San Marco Concrete Art in a warm greige tone — a color that complemented their existing furniture without competing with it.

The process

Surface preparation: the drywall tape ridge was lightly sanded, skim-coated, sanded again, and feathered into the surrounding wall. The San Marco Marcotherm Primer was applied to the entire feature wall and allowed to cure overnight. This unified the surface porosity across the wall — critical for even color absorption with mineral plaster.

First coat of Concrete Art: applied with a fine-finish trowel in overlapping strokes, building a thin, consistent base layer. The material was worked while still wet to minimize trowel lines. Drying time: six hours.

Second coat: applied with slightly more material, working in a direction perpendicular to the first coat. At certain sections, the trowel was dragged with less pressure, leaving subtle variation in material thickness — lighter passages where less product sat on the wall, slightly richer passages where more product accumulated. This controlled variation is what creates the 'concrete' quality.

Third coat and finishing: a thin final coat was applied selectively — not uniformly — to build depth in the areas that needed it. After partial setting, certain areas were lightly burnished with a clean trowel to create a slight sheen contrast across the wall. No wax seal was applied (the client preferred the fully matte finish).

The outcome

The tape ridge disappeared entirely. The color shift from the prior paint was undetectable beneath the mineral primer and three coats of Concrete Art. The wall — which had been the least interesting element of a reasonably well-designed room — became its visual anchor.

The client's observation: 'It looks like we had an architect come in and do something expensive. We didn't. We just did the one wall.' That encapsulates the value proposition of San Marco decorative plasters: the transformation is disproportionate to the cost and effort involved.

Section 7: How to Apply San Marco Decorative Plaster — Step by Step

The following guide applies to San Marco plaster products including Concrete Art and Marmorino, applied to a standard American drywall living room feature wall. Allow two days: Day 1 for preparation and priming, Day 2 for the decorative finish application.

What you will need

•       San Marco decorative plaster (Concrete Art or Marmorino) — quantity: wall area in sq ft × 3 coats ÷ 54, plus 15% buffer

•       San Marco compatible primer (Marcotherm Primer recommended — available at The Decora Company)

•       Fine-finish trowel or spatula — The Decora Company carries Pennelli Tigre professional tools

•       Natural-bristle brush for Marmorino burnishing

•       Flexible filler for any cracks or drywall tape ridges

•       120-grit sandpaper and sanding block

•       Masking tape and plastic sheeting for edge protection

•       Clean rags for wiping and clean water

•       Protective gloves — mineral plasters are alkaline

Day 1: Surface preparation and priming

Step 1 — Inspect and repair

Examine the wall in raking light — hold a flashlight at a low angle across the surface to reveal any cracks, tape ridges, or surface irregularities. Fill cracks with flexible filler and allow to cure fully (4–6 hours for hairline cracks, 24 hours for larger fills). Sand flush and remove all dust with a damp cloth.

Step 2 — Clean the surface

Wipe the entire wall with a clean, slightly damp cloth to remove dust and any surface oils. If the existing paint is semi-gloss or gloss, lightly sand the entire surface to create a mechanical key for the primer. Remove all sanding dust.

Step 3 — Apply San Marco primer

Apply the San Marco Marcotherm Primer with a brush or short-pile roller in a single even coat. The primer serves two functions: it unifies surface porosity across the wall (so the decorative plaster absorbs at a consistent rate and does not create blotchy color) and provides the chemical adhesion base that mineral plasters require. Allow to dry fully — minimum 4 hours, ideally overnight.

Day 2: Three-coat decorative finish

Step 4 — First coat

Open the San Marco plaster and stir thoroughly — pigment can settle. Apply the first coat with your trowel in overlapping strokes at varying angles, working in sections of approximately 2 sq ft. Keep a wet edge at all times to prevent lap lines. The first coat should be thin and slightly uneven — it is establishing the base, not achieving the final look. Allow to dry 4–6 hours.

Step 5 — Second coat with directional variation

Apply the second coat slightly thicker than the first, working in a direction roughly perpendicular to your first coat strokes. As you work, vary your trowel pressure deliberately — lighter pressure in some areas, slightly more in others. This variation creates the tonal depth that defines the finished wall. Work quickly; the product begins to set within 10–15 minutes of application. Allow to dry 4–6 hours.

Step 6 — Third coat and finish technique

The third coat is where the finish quality is determined. Apply selectively — build additional depth in areas that need it rather than coating the entire wall uniformly. For Marmorino: after partial setting (approximately 15–20 minutes), burnish with a clean, dry steel trowel using firm circular pressure. This compresses the surface and creates the characteristic polished sheen. For Concrete Art: a light trowel drag while partially set creates the matte concrete quality. Allow to cure 24–48 hours before placing anything against the wall.

 

▌

Technique note — the most common DIY mistake Over-working a section after the product has begun to set. Once you feel the material pulling away from the trowel with resistance, stop. Move to an adjacent section and return to that area on the next coat. Working into setting material creates dragged marks that are extremely difficult to correct.

Section 8: Choosing Your San Marco Color and Finish

San Marco's color system

San Marco organizes its color palette into four mood collections — Energy, Minimal, Soft, and Black & White — each reflecting a distinct design direction. For American living rooms, the Minimal and Soft collections are consistently the most-selected: warm whites, soft stone tones, warm greys, aged linens, and dusty greens that read as neutral in photographs but rich and layered in person.

The three rules of limewash color selection

Rule 1: Always sample on your actual wall

Mineral plasters dry significantly lighter than they appear in the container — typically 30–50% lighter, depending on pigment load and the number of coats. A color that appears as a medium warm grey in the sample card may dry to a pale silver on your wall. Always purchase a sample quantity, apply it to your actual wall surface (not a test board — wall porosity affects color differently), allow it to cure fully for 48 hours, and observe it at different times of day before ordering full quantity.

Rule 2: Warm undertones outperform cool in living rooms

Cool whites and cool greys tend to read as institutional and cold in residential living rooms, particularly under artificial lighting. Warm tones — whites with a yellow or pink undertone, warm beige-greys, soft ochres, dusty sage greens — create the sense of enclosure and comfort that a living room feature wall should deliver. The lighting in your room matters: north-facing rooms (cooler, bluer light) benefit from warmer tones; south-facing rooms (intense warm light) can balance with slightly cooler tones.

Rule 3: Consider the whole room, not just the wall

A limewash or mineral plaster feature wall will read differently depending on the colors of the other three walls, the floor, the furniture, and the textiles in the room. San Marco's online Paint Visualizer tool (available at en.san-marco.com) allows you to upload a photo of your space and test colors digitally before ordering samples. This is a useful first step — not a replacement for physical samples, but a strong way to narrow the field before spending on sample pots.

Section 9: Frequently Asked Questions

The following questions are the ones The Decora Company team receives most consistently from US homeowners considering a San Marco decorative plaster project.

Can San Marco plaster be applied over existing latex paint?

Yes — if the existing paint is fully bonded, non-flaking, and free of peeling sections. You must apply a San Marco compatible primer (the Marcotherm Primer available at The Decora Company is recommended) to create the adhesion base that mineral plasters require. Latex paint that is peeling, powdery, or insufficiently bonded must be removed before application. When in doubt, call The Decora Company at (608) 620-5066 — they can advise on substrate preparation for your specific wall condition.

Does San Marco plaster work on drywall?

Yes. American drywall is the primary substrate for the majority of Decora Company customers. The key requirement is that the drywall surface must be properly primed — unsealed or poorly sealed drywall will absorb moisture from the mineral plaster too quickly, preventing proper bonding and creating uneven color. The Marcotherm Primer system is designed specifically to create a consistent, sealed surface on drywall before decorative plaster application.

How much product do I need for a living room feature wall?

For a typical US living room feature wall of approximately 10 feet × 9 feet (90 sq ft): at a coverage rate of approximately 50–60 sq ft per liter per coat, and three coats, you will need approximately 4.5–5.5 liters of product. Always order the higher end of your calculation plus 15%, as running out mid-project and needing to re-order can create visible differences in tone between sections applied on different days. The Decora Company team can calculate exact quantities for your specific wall dimensions — contact them before ordering.

Can I take a class before starting my project?

Yes — and for first-time applicators, a class is strongly recommended. The Decora Company offers in-person application classes covering San Marco decorative plaster techniques. The classes cover surface preparation, primer application, the multi-coat process, trowel and burnishing technique, and troubleshooting. Visit thedecoracompany.com/pages/classes for current class schedules and booking.

How long does a San Marco decorative plaster finish last?

A properly applied San Marco mineral plaster on a stable interior wall lasts 10–15 years for Concrete Art and brushed finishes, and 20+ years for burnished Marmorino. Unlike paint, these finishes do not chip and peel as a surface film. They age. The color deepens and matures over time — most clients find their mineral plaster wall looks better at five years than at one year. Touch-up application, when needed, blends naturally into the existing finish because the mineral chemistry is consistent across applications.

What is the difference between San Marco's various plaster products?

The primary distinctions are in finish texture and application method. Marmorino Classico produces a polished, satin, stone-like finish achieved by troweling and burnishing — the most traditional Italian lime plaster result. Concrete Art produces a matte, fine-grain concrete-effect finish applied with a trowel — more contemporary in aesthetic and somewhat more forgiving for first-time applicators. Marcopolo Luxury is a metallic decorative paint rather than a plaster — applied with a brush or pad, it creates a metallic shimmer effect suitable for accent walls. The Decora Company team can recommend the right product for your space and skill level.

What is the return and shipping policy?

The Decora Company offers free shipping on all US orders over $395. For most feature wall projects that require decorative plaster plus primer, this threshold is straightforward to reach. For specific shipping rates, return policies, and order processing times, visit thedecoracompany.com or call (608) 620-5066.

Section 10: How to Order from The Decora Company

Step 1: Identify your finish

Use Section 4 of this guide to identify which San Marco finish is right for your space and application context. If you are unsure, call The Decora Company at (608) 620-5066 or email info@thedecoracompany.com — the team has spent over ten years advising on exactly this question and can narrow your options in a five-minute conversation.

Step 2: Order a sample

Before ordering full project quantity, purchase a sample of your chosen color. Apply it to your actual wall — not a test board — and allow it to cure for 48 hours. Observe it at different times of day. Confirm your color before placing the full order. Samples are available through the product pages at thedecoracompany.com.

Step 3: Calculate your quantity and order

Measure your wall in square feet (height × width). Divide by your product's coverage rate (approximately 50–60 sq ft per liter per coat). Multiply by 3 (three coats). Add 15%. This is your order quantity. For a 10 × 9 ft wall: 90 ÷ 55 × 3 = 4.9 liters, plus 15% = approximately 5.6 liters. Round up to the nearest package size.

Step 4: Consider adding professional tools

The quality of a mineral plaster application is substantially determined by the quality of the tools used. The Decora Company carries Pennelli Tigre professional trowels, spatulas, and brushes — the same tools used by professional decorators in Italy and in the US. Adding the right trowel for your specific finish to your order is a high-value decision. See the full tools range at thedecoracompany.com/collections/tools.

Step 5: Consider attending a class

If this is your first San Marco application, attending a class before starting your project is strongly recommended. See current class dates at thedecoracompany.com/pages/classes.
