Polished Italian lime plaster with the depth, movement and cool lustre of solid stone. Applied by a Novacolor certified applicator โ which on these systems is not a brag, it's the condition the 10-year warranty is written on.
Master PaintersVenetian plaster is a lime-based plaster built up in ultra-thin layers and burnished back with a steel trowel. It isn't a paint effect and it isn't a texture coat. It's real slaked lime and marble dust, compressed until the surface takes on the cool, glassy depth of polished stone.
The look comes from what's underneath. Each coat is troweled in different directions, so light entering the wall passes through several layers before it reflects โ which is why a Venetian plaster wall shifts as you walk past it and a painted wall never does. It's also breathable and naturally alkaline, which is why it sits so well on older Auckland plaster and masonry.
The name covers a whole family of finishes, not one product โ and that's the thing most people get stuck on. The types are explained below, or jump to colours, cost, or a free instant estimate.
"Venetian plaster" is a category, not a product. Nearly every enquiry we get starts with someone who has seen a finish they love and doesn't know what it's called. Here's the family, plainly.
| The finish | Texture & sheen | Best for |
|---|---|---|
| Marmorino | Fine marble aggregate, subtle stone-like movement. Matte to satin. | The default. Feature walls, whole rooms, ceilings. |
| Stucco Veneziano | The high-polish one. Glassy, mirror-like, deep marble veining. | Statement walls, entries, powder rooms, bars. |
| Grassello di Calce | Pure lime putty, very smooth, high sheen when burnished hard. | Formal rooms, heritage restoration, ceilings. |
| Tadelakt | Seamless, soapy-smooth, soft sheen. Traditionally soap-sealed. | Bathroom walls, vanities, curved forms, niches. |
| Travertino | Pitted and pored like real travertine stone. Matte. | Feature walls wanting visible stone character. |
| Concrete effect | Flat, cloudy, industrial. Matte, no polish. | Modern builds, commercial, minimalist interiors. |
| Metallic & oxidised | Pearlescent shimmer or rusted-iron patina. | Bars, retail, single dramatic walls. |
Literally "little marble". Slaked lime with finely crushed marble, which is what gives the surface its quiet stone-like movement. It's the most versatile of the family and the one we specify most often โ it reads beautifully in a whole room without shouting. We apply Novacolor Marmorino KS.
The finish most people picture when they say "Venetian plaster": burnished to a genuine polish, almost wet-looking, with deep marble veining that moves as the light moves. It's the most labour-intensive of the range, and it wants a single well-lit wall rather than a whole house.
Moroccan in origin, seamless and slightly soapy to the touch, with a soft rather than glassy sheen. The one lime finish with a genuine claim to bathroom walls, because it's traditionally sealed to shed water. We apply Novacolor Archi+ Tadelakt.
Where Marmorino is smooth, these carry real physical texture โ the pits and pores of travertine, or the coarse grain of a natural aggregate. Best where you want the wall to be touched as well as looked at.
The quietest end of the family: chalky, powdery, no sheen at all. Closer in feel to lime wash but with real plaster body. Novacolor Calce Cruda is the one we reach for in bedrooms and snugs.
Flat, cool and cloudy โ the poured-concrete look without the slab. Suits modern Auckland builds with black joinery, and it's the finish most often asked for by architects rather than homeowners.
Send us the photo. Nine times out of ten we can name the finish off a screenshot, and tell you honestly whether it's the right call for your wall and your light.
Lime plaster is tinted, not painted, so the colour sits inside the surface and shifts with the light through the day. Auckland's light is bright but often overcast, which flatters the warm neutrals and can make cold greys read grey-blue and lifeless. This is the palette that actually works here.
| Colour family | How it reads | Where it works |
|---|---|---|
| Warm white & bone | Soft, luminous, never sterile. The safest choice and the most requested. | Whole rooms, ceilings, villas, north-facing living |
| Greige & putty | The quiet workhorse. Reads warm in daylight, deeper under lamps. | Living rooms, hallways, open plan |
| Clay, sand & terracotta | Earthy warmth with visible movement. Very current. | Feature walls, bedrooms, fireplaces |
| Stone grey & taupe | Warm-leaning greys. Avoid the cold blue-greys in Auckland light. | Modern builds, bathrooms, kitchens |
| Deep charcoal & ink | Dramatic and enveloping. Shows the burnish best of any colour. | Dining rooms, bars, powder rooms, media rooms |
| Muted green & olive | Softer than a painted green because of the tonal movement. | Studies, bedrooms, joinery-heavy spaces |
Two things worth knowing. It dries lighter than it goes on, so wet plaster is never the colour you're judging. And a sample board in a showroom tells you almost nothing โ the same plaster reads differently on a north wall and a south wall in the same house. We bring boards to site and leave them with you for a few days so you see them in your own light, morning and night, before anything is ordered.
One wall is usually all it takes. Venetian plaster is a statement finish โ it works best where the room already wants a focal point.
The classic. A single polished wall behind a bed, sofa or dining table gives a room the weight of a stone building.
Plaster wrapping a fireplace reads as solid, carved mass โ the effect people are chasing when they say "monolithic".
Tall walls with raking light are where burnished plaster earns its money. The movement is strongest where the light is sharpest.
Sealed Venetian plaster handles a splashback and island face beautifully โ seamless, wipeable and far warmer than a glass panel.
Colour-drenching a ceiling or a nook in the same plaster is the detail that makes a room feel designed rather than decorated.
Bars, showrooms and clinics โ a hard-wearing mineral surface that photographs far better than paint and ages instead of scuffing.
Usually yes โ but the substrate decides how much prep the quote carries, and prep is the single biggest variable in the price. Here's the honest answer for each.
| Surface | Can we? | What's involved |
|---|---|---|
| New Gib / plasterboard | Yes โ ideal | Needs a Level 5 finish. Level 4 will telegraph joints through a polished surface. |
| Existing painted walls | Yes | Sand, make good, then a keyed primer so the plaster has something to grip. |
| Solid plaster / render | Yes | Often the best substrate there is, once cracks are cut out and made good. |
| Brick & block | Yes | Needs a levelling render coat first. Adds cost, but the result is superb. |
| Villa lath & plaster | Usually | Depends on how sound it is. We probe it before quoting rather than after. |
| Existing tiles | Not recommended | Movement and grout lines telegraph. Use microcement instead. |
| Inside a shower | No | It's not a waterproofing system. Microcement is. |
| Exterior walls | Case by case | Some lime systems are rated for it. Auckland's rain and salt air narrow the options โ ask us. |
The short version: flat and sound beats new every time. We'd rather plaster a hundred-year-old wall that's been made good properly than a new Level 4 board.
The honest version, including the rooms where we'd steer you somewhere else.
| Room | Our call | Why |
|---|---|---|
| Living & dining | The sweet spot | Big walls, good light, and the room you sit in longest. Marmorino on one wall, or colour-drench the lot. |
| Bedrooms | Yes โ go matte | A polished sheen can feel cold behind a bed. Calce Cruda or a matte lime reads softer and calmer. |
| Entry & stairwell | Best value in the house | Tall walls, raking light, and it's the first thing anyone sees. The movement is strongest here. |
| Bathrooms | Yes, with conditions | Walls away from direct spray, vanity walls, and Tadelakt where you want a wet-look finish. Not inside the shower. |
| Kitchens | Yes โ seal it | Splashbacks and island faces work beautifully sealed and waxed. Seamless, wipeable, warmer than glass. |
| Fireplaces | The most-requested | Wrapping a chimney breast reads as carved solid mass. Heat is not an issue away from the firebox itself. |
| Ceilings | Underrated | Plastering the ceiling in the same tone is the detail that makes a room feel designed. Slow to apply, worth it. |
| Hallways | Yes โ wax it | Bags, shoulders and dog tails. Sealed and waxed it takes the traffic; unsealed in a narrow hall it will mark. |
| Laundries & WCs | Great small win | Small rooms are cheap to do and high impact. A powder room in deep charcoal Stucco Veneziano is a showpiece. |
| Inside showers | No โ use microcement | Not a waterproofing system. Microcement is, and it's wet-area compliant. |
| Exterior walls | Case by case | Some lime systems are rated for it, but Auckland rain and salt air narrow the options. Ask before you plan it. |
This is the part nobody else writes about, and it's the strongest practical argument for lime plaster in this country. New Zealand homes are damp. We have high humidity, long wet winters, and a huge stock of older houses that were built to breathe and have since been wrapped in modern sealed paint.
Lime plaster is vapour-permeable. Moisture moves through it instead of being trapped behind a plastic film, which is exactly what a villa's original walls were designed to do. Seal those walls with a modern acrylic and the moisture has nowhere to go but into the timber behind.
Lime is naturally alkaline, at a pH that mould does not enjoy. It's not a mould treatment and we won't claim it is โ if you have a moisture problem you need to fix the moisture problem โ but in a bedroom that runs a bit damp, a breathable mineral wall behaves very differently to a sealed painted one.
And it gets harder with age. Lime slowly reabsorbs carbon dioxide and returns toward the limestone it started as. Paint is the only wall finish you own that begins failing the day it dries; lime plaster is the opposite.
Most of the bad Venetian plaster in Auckland isn't bad product. It's the wrong hands, or the right hands rushed. Four questions worth asking whoever you get a price from โ including us.
| Ask them | What a good answer sounds like |
|---|---|
| "Are you certified with the manufacturer?" | A named certification, not "we've done heaps of it". On Novacolor and Cemher the warranty is void without it. |
| "What level will you prep the wall to?" | Level 5, and they should raise it before you do. If they don't mention prep, the joints will telegraph. |
| "How many coats, and how long on site?" | Coats named, days given. Two days for a feature wall is realistic; one day is someone skipping a coat. |
| "Can I see a sample in my own room?" | Yes, and they leave it with you. A showroom board in showroom lighting tells you almost nothing. |
The three failures we get called to fix: telegraphing (joints and ripples showing through because the wall wasn't made good), patchiness (coats applied too fast, or burnished after the window closed), and dusting (wrong primer, so the plaster never properly keyed to the wall). All three are prep and process, not product โ and all three are expensive, because the only honest fix is to take it back off.
This is the question we get asked most, and the honest answer costs us nothing โ we're certified in both, so we have no reason to push you to the wrong one.
| Venetian Plaster | Microcement | |
|---|---|---|
| Made of | Slaked lime and marble dust โ a mineral plaster | Cement-based polymer-modified system |
| Look | Polished, glassy depth with marble-like movement | Matte to satin, even stone-like tone, subtle trowel texture |
| Build-up | Very thin โ layers measured in fractions of a millimetre | 3-4mm over the existing surface |
| Wet areas | Not for showers. Splashbacks yes, wet rooms no | Made for them โ fully waterproof system, wet-area compliant |
| Floors | Walls and ceilings only | Walls, floors, benchtops and stairs |
| Over tiles | No | Yes, over sound tiled surfaces |
| Best for | Feature walls, fireplaces, stairwells, ceilings | Bathrooms, showers, seamless floors, benchtops |
Straight answer: if it's a wall you want to look carved from stone, it's Venetian plaster. If water is going to hit it or you're going to walk on it, it's microcement. Plenty of homes use both โ plaster in the living room, microcement in the bathroom.
All four get called "a textured feature wall" by someone. They behave completely differently, and they're not close on price.
| Depth | Durability | Relative cost | The catch | |
|---|---|---|---|---|
| Venetian plaster | Deepest โ real stone-like polish | Decades. A mineral surface, not a film | Highest | Wants a flat substrate and a skilled hand |
| Lime wash | Soft, chalky, cloudy | Ages rather than fails | Around a third of Venetian | Matte only โ no sheen, no polish |
| French wash | Watercolour movement over a base coat | Good, it's a glaze over paint | Lower again | Softer effect, less physical presence |
| Textured paint | Shallow, repeats visibly | Standard paint life | Lowest | Reads as paint close up, every time |
| Plaster-look wallpaper | Printed, so it repeats | Seams, and it can lift | Low to mid | No depth under raking light. It's a photo of plaster |
We apply the first three and we'll tell you when lime wash is the smarter spend. If the budget is tight and the room is big, a beautifully executed lime wash beats a rushed Venetian every time.
We're certified across two systems, and they suit different jobs and different budgets.
The real thing: lime and marble plasters made in Italy. Marmorino KS for smooth satin walls with tonal movement, Archi+ Tadelakt for a polished spa-like sheen, Teodorico for the semi-polished marble look, Calce Cruda for a soft matte lime-and-clay finish. Deepest, most authentic result, and it carries a 10-year product warranty when a certified applicator lays it down.
Porter's own polished plaster: thinner, softer-sheen, applied in fewer coats. It gets you most of the way to the burnished stone look for less time on site, which often makes it the smarter spec on a large wall or a tighter budget. Applied under our Porter's Applicators Guild accreditation.
We look at the wall, the substrate and the light through the day, then leave real plaster sample boards with you โ colour and sheen signed off before anything is ordered.
Free ยท No obligationPolished plaster is unforgiving: every flat spot and every ripple shows. Walls are made good to a Level 5 standard and primed with the system's own base before a trowel touches them.
Base coat, then the thin colour coats, each troweled in crossing directions and left to pull. This is where the depth is made โ it cannot be added later.
The surface is compressed with a clean steel trowel until it takes its sheen, then sealed or waxed to suit the room. We hand over with care guidance.
Venetian plaster is a multi-coat, hand-burnished system, so it's priced by the surface, the prep and the sheen level โ not by the litre. A single feature wall is the usual entry point.
A typical 8-12mยฒ feature wall lands around $1,800-$3,200. A full feature room of roughly 35mยฒ starts around $8,000. Those are indicative, not a quote โ read the full 2026 Auckland price guide.

Try the free estimator โ Or book a free consult No obligation ยท No spam ยท Just a clear next stepAlmost nothing, which is the point. But there are three things worth knowing before you commit.
Dust it, or wipe with a barely damp cloth. No abrasives, no bleach, nothing acidic โ lime is alkaline and acid etches it. Sealed and waxed walls in kitchens tolerate a mild soap.
Because the colour runs through the plaster rather than sitting on top, a light scuff often burnishes out with a soft cloth. Deeper damage is patched and re-burnished โ unlike paint, it can be made invisible.
Decades. It's the same material still standing on Italian buildings centuries later. It doesn't peel or flake because it isn't a film โ it's part of the wall.
A decent chunk of our plaster work comes through designers rather than direct. Here's how we work with you.
Send elevations and we'll price off them โ no site visit needed to get a budget number into a schedule. We'll flag where the substrate spec needs to change to carry the finish.
Real plaster on board, in the actual colour and sheen, for your presentation. We'll do multiple options side by side so the client chooses from material, not a render.
If you need spec text for a tender we'll write it โ system, coats, substrate standard, sealer and maintenance. Named products, so the price you get back is comparable.
The single most common project problem: plaster specified over a Level 4 board finish. We'd rather raise it at design stage than argue about telegraphing at handover.
Plaster goes on late, after the dust-making trades and before final fit-off. We'll tell you where it sits in your programme and how many days to hold.
We'll invoice you or your client, present in your name or ours, and stay out of the way if you'd rather we weren't in the room. Master Painters accredited, $10m insured, Site Safe.
Quotes for this work are full of jargon. Here's what it all actually means, so you can compare two prices properly.
| Term | What it means |
|---|---|
| Slaked lime | Limestone burnt and then soaked in water. The binder in every finish on this page โ what makes it breathable and alkaline. |
| Burnishing | Compressing the surface with a clean steel trowel. Not polishing with a cloth โ it's pressure, and it's where the sheen comes from. |
| Marble dust | The aggregate. How finely it's ground decides whether you get a smooth polish or a visible stone texture. |
| Level 4 / Level 5 | Plasterboard finishing standards. Level 4 is normal for paint. Polished plaster needs Level 5 or joints telegraph through. |
| Telegraphing | When what's underneath shows through the finish โ joints, patches, ripples. The most common failure, and it's a prep failure. |
| Keyed primer | A gritty primer that gives the plaster something to grip. Skip it and the finish can dust off the wall later. |
| Sheen level | How reflective the finished surface is, from dead matte to mirror polish. Decided by the product and how hard it's burnished. |
| Patina | The way the surface changes with age and light. On lime it's a feature, not wear. |
| Carbonation | Lime reabsorbing CO2 and hardening back toward limestone. Why these walls get tougher over years rather than degrading. |
