Decorative Plaster

What Is Decorative Plaster?

Decorative plaster is a broad term covering a range of hand-applied, specialist plaster finishes that go well beyond the smooth, flat surface of standard plastering. These are statement finishes - designed to be the final decorative surface in their own right, without the need for paint or wallpaper.

The most well-known type is Venetian plaster (also called polished plaster or stucco lustro), a technique developed in Venice centuries ago using slaked lime and crushed marble. Applied in multiple ultra-thin layers and burnished to a high sheen, it produces a surface with extraordinary depth, subtle colour variation and a natural lustre that no paint finish can replicate.

Lee on decorative plaster

Decorative plaster is a specialist field within plastering, and the honest answer is it’s not my day-to-day work. I specialise in modern plastering, skim coating, rendering, full replasters, that’s where I’ve put my decades. For Venetian polished plaster, Marmorino, ornate decorative finishes, I work with a trusted partner who’s a specialist in that side of the trade. Customers who come to Perfect Plastering for decorative work get directed to the right hands. It’s the same approach I take with cornicing restoration on listed buildings: the right person for the right job, not me pretending to be a Venetian plaster master.

Types of Decorative Finish

Venetian Polished Plaster

The classic. Multiple thin coats of lime-based plaster containing fine marble particles are applied with a flexible steel trowel, each layer adding depth and translucency. The final surface is burnished to a polished sheen that catches and reflects light, creating a finish that looks and feels like natural stone. Venetian plaster suits both contemporary and period interiors and is particularly striking on feature walls, in hallways and in bathrooms.

Marmorino

A traditional Italian finish closely related to Venetian plaster but with a slightly more textured, matte-to-satin appearance. Marmorino uses coarser marble particles than standard Venetian plaster, producing a finish with more visible texture and a softer sheen. It is ideal for creating a warm, natural stone effect and works beautifully in period properties across Canterbury and the surrounding villages.

Textured and Trowelled Finishes

Not all decorative plaster is smooth and polished. Textured finishes - including travertine effects, concrete-look plasters and rustic stone effects - are increasingly popular in modern and industrial-style interiors. These finishes use specialist plasters applied with various trowel techniques to create surfaces that mimic natural materials or create bold, sculptural textures.

Metallic and Specialist Effects

For clients looking for something truly unique, metallic plaster finishes incorporating real metal particles (copper, bronze, iron, silver) can be applied to create surfaces that develop a genuine patina over time. These are typically used as feature panels or accent walls rather than whole-room treatments.

Lee on the finishes the team handles

Through the specialist partner, the team handles the full range of decorative finishes you’d expect: Venetian polished plaster, Marmorino, textured trowelled finishes and modern concrete-look effects. The most popular are still the polished plaster feature walls in hallways and living rooms, and Marmorino in bathrooms as an alternative to tiling. Demand for the more dramatic metallic and patina finishes is smaller but it’s there, usually for commercial clients or high-end residential refurbs.

Materials We Use

Decorative plastering demands specialist materials quite different from the British Gypsum Thistle products used in standard plastering. We work with premium lime-based plasters from established manufacturers:

• Viero - Italian manufacturer producing a comprehensive range of polished plaster, Marmorino and textured finishes, widely regarded as among the best in the industry
• Armourcoat - UK-based company offering high-quality polished plaster systems with excellent colour consistency and technical support
• Novacolor - Premium Italian plasters with an extensive range of decorative effects and finishes
• Venetian Plaster Company - Specialist supplier with a range suited to both traditional and contemporary applications

The choice of product depends on the specific finish required, the environment (wet areas need different formulations to dry rooms), and the look the client wants to achieve.

Lee on brand choice

The brand selection is led by the specialist who applies the finish, because the right product depends on the look the customer wants and the conditions. The reputable premium brands like Armourcoat and the Italian ranges from Viero and Novacolor are excellent, and that’s where most of our jobs end up using product from. The brand matters less than the application skill, but cheap product will let you down even with a good applicator, so we don’t take shortcuts on materials.

Our Application Process

Surface Preparation

Decorative plaster amplifies every imperfection in the surface beneath it. Preparation is therefore critical and often takes as long as the application itself. We ensure the substrate is flat, smooth, dry and properly primed with a product compatible with the chosen plaster system. On new plaster, we allow full drying time before beginning. On existing painted walls, we apply a specialist bonding primer.

Base Coat

A dedicated base coat is applied to create a uniform surface in terms of both texture and suction. This coat is typically colour-matched to the finish coats to ensure consistent depth of colour.

Application Coats

This is where the craft lies. Each coat of decorative plaster is applied by hand with a steel trowel in thin, overlapping strokes. The angle, pressure and direction of the trowel determine the pattern and movement in the finished surface. Typically three to five coats are applied, with each coat partially covering the one below to build up the characteristic depth and translucency.

Burnishing and Sealing

The final coat is allowed to firm up before being burnished with a clean steel trowel. The pressure and heat from the trowel compress and polish the surface, bringing out the sheen and highlighting the natural variation between layers. Once burnished, the surface is sealed with a natural wax or specialist sealer, depending on the environment and the level of protection required.

Lee on timescales

A typical feature wall takes the best part of a week start to finish, even for a relatively small area. Each coat goes on thin, and each coat needs to firm up before the next one goes on, so the curing time between layers is what stretches the job out. The actual application is fast in the hands of someone experienced; the patience is in waiting between coats and getting the burnishing right at the end. Preparation can take as long as the application itself, because any imperfection in the wall underneath shows through the finish.

Where Decorative Plaster Works Best

Decorative plaster is a premium finish and is typically used in areas where it will have the most visual impact:

• Feature walls in living rooms and bedrooms
• Hallways and entrance areas where first impressions matter
• Bathrooms and en-suites as a luxurious alternative to tiles
• Fireplaces and chimney breasts as a focal point
• Commercial spaces including restaurants, hotels, bars and retail interiors

Across East Kent, we have applied decorative plaster in a range of settings, from contemporary apartments in Whitstable to period townhouses in Canterbury. The finish works in both modern and traditional interiors, depending on the colour, texture and level of polish chosen.

Costs and What Affects Them

Decorative plaster starts from around £80 per square metre, but the final cost depends on several factors:

• Type of finish - a simple two-tone polished plaster is less labour-intensive than a complex Marmorino or metallic effect
• Number of coats - more coats means more time and material
• Surface preparation - walls in poor condition require more preparatory work
• Area and complexity - small, fiddly areas with lots of corners and edges take proportionally longer than large, open walls
• Material choice - premium products from Armourcoat or Viero cost more than entry-level ranges

We provide detailed quotations based on a site visit, so there are no surprises. Given the investment involved, we always recommend seeing samples of the chosen finish applied to a test panel before committing to a full room.

Lee on typical projects

The most common decorative plaster project is a feature wall, in a living room, bedroom or hallway, where the customer wants something more than paint or wallpaper as a focal point. Full rooms come up less often because the cost scales quickly. Commercial work, restaurants, bars, hotels, comes through the specialist on the team and tends to be higher-spec, sometimes including metallic or patina finishes. Budgets vary hugely depending on the finish and the area, but it’s a premium product, so customers come with that expectation.
