Painting a New-Build Apartment: Why Developer Finishes Fail and How to Upgrade

London's new-build apartment market has boomed over the past fifteen years. Developments across Battersea, Nine Elms, Fulham, Pimlico, and beyond have delivered thousands of new homes, many of them marketed as luxury or premium. Yet one of the most common complaints from new-build buyers, regardless of the price point, is the quality of the internal paintwork. Walls that mark within weeks, ceilings that show roller marks in certain light, patchy coverage over fresh plaster, and a general air of haste rather than craftsmanship.

This is not a reflection of the paint itself, but of the process by which new-build apartments are decorated. Understanding why developer finishes fail, and what to do about it, can save new homeowners significant frustration and expense.

Why Developer Finishes Are Poor

The Economics of Development

The internal decoration of a new-build apartment is, from the developer's perspective, a cost to be minimised. The price of the property is determined primarily by location, square footage, specification of kitchens and bathrooms, and the brand of the development itself. The quality of the paintwork, while noticed by every occupant, is rarely a selling point.

As a result, the decorating budget for a new-build apartment is typically tight. This affects every aspect of the finish:

• Paint quality: Developers commonly use trade-grade contract matt emulsion, the cheapest category of interior paint. Products in this category are designed primarily for coverage and economy, not for durability, washability, or aesthetic quality. They go on quickly, cover reasonably well, and cost a fraction of premium paints.
• Number of coats: Contract specifications often call for just two coats of emulsion directly onto new plaster, sometimes over a mist coat and sometimes not. Premium paints like Farrow & Ball or Little Greene are typically applied in two to three coats over a proper primer for best results. Developer decorators rarely have the time or budget for this approach.
• Labour: Decorating new-build apartments is fast-paced, high-volume work. Decorators are often paid by the unit rather than by the hour, creating an incentive to work quickly. There is limited time for careful preparation, cutting in, or achieving a truly even finish.
• Programme pressure: The overall construction programme drives everything. Decorating happens late in the build process, often while other trades are still finishing work in adjacent rooms. Dust from sanding, debris from final-fix plumbing and electrical work, and general site activity all compromise the finished paintwork.

The Plaster Problem

New plaster presents specific challenges for painting. Fresh plaster contains a significant amount of moisture, which must evaporate before the plaster is ready to receive paint. Industry guidance suggests that new plaster should be left to dry for at least four weeks before painting, and longer in cold or humid conditions.

In practice, the construction programme rarely allows for this. Apartments are frequently painted before the plaster is fully dry, which leads to several problems:

• Mist coat failure: A mist coat (a thinned first coat of emulsion) is essential on new plaster to seal the surface and provide a key for subsequent coats. If applied to damp plaster, the mist coat cannot bond properly and may peel or flake later.
• Efflorescence: Mineral salts in the plaster migrate to the surface as moisture evaporates, leaving white, crystalline deposits beneath or on top of the paint film.
• Cracking: As new plaster dries and the building settles, hairline cracks often appear, particularly around door frames, window reveals, and the junction between walls and ceilings. These are normal and expected in the first year or two, but they look unsightly through a thin coat of contract paint.

The Settlement Factor

New buildings move. Concrete frames shrink slightly as they cure. Timber components dry out and contract. The building settles under its own weight. All of this movement causes minor cracking in plasterwork and along joints. In the first twelve to eighteen months, these cracks are most active. Developer decorators paint the walls before most of this movement has occurred, so the cracks appear through the fresh paint.

This is why many industry professionals recommend waiting at least a year before carrying out any significant redecoration of a new-build property. It allows the building to complete its initial settlement, after which cracks can be filled and the property properly decorated.

The Snagging Process

Before completing your purchase, you should carry out a thorough snagging inspection. A professional snagging company will identify defects throughout the property, including paintwork issues. Common paint-related snags include:

• Misses and holidays: Areas where the paint has not been applied or coverage is incomplete.
• Roller marks and tramlines: Visible lines in the paint film caused by poor rolling technique or insufficient laying off.
• Brush marks on woodwork: Runs, sags, and visible brush strokes on skirting boards, architraves, and door frames.
• Poor cutting in: Uneven lines where walls meet ceilings, where different colours meet, or where paint meets tiles and other fixed surfaces.
• Overspray and splashes: Paint on surfaces where it should not be, such as windows, hardware, or flooring.
• Uneven colour: Variations in shade across a wall, often caused by inconsistent mixing or application.

All of these should be recorded and submitted to the developer for rectification under the terms of your warranty. However, be realistic about the outcome. Developer remedial painting is often carried out by the same team that did the original work, under the same time pressure, and the results may not be significantly better.

The Upgrade Path

When to Repaint

As noted above, the ideal time to carry out a full redecoration of a new-build apartment is approximately twelve to eighteen months after completion. By this point, the major settlement cracking will have occurred, the plaster will be fully dry, and you will have a clear picture of any underlying issues.

However, if the existing paintwork is particularly poor, there is nothing wrong with repainting sooner. Just be prepared for the possibility that some hairline cracks may appear in the new paintwork as settlement continues, and plan for a touch-up session six to twelve months later.

Preparation

Repainting a new-build apartment is relatively straightforward compared to redecorating an older property, because the surfaces are generally in good condition beneath the poor paint.

Step 1: Fill cracks. Use a flexible filler such as Toupret or Gyproc EasiFill for hairline cracks. For wider cracks, particularly at wall-ceiling junctions, a caulk applied with a mastic gun provides a flexible, permanent seal that will accommodate ongoing minor movement.

Step 2: Sand. Lightly sand all walls and ceilings with 120-grit or 150-grit sandpaper to key the surface and smooth out any imperfections, roller marks, or raised areas of filler.

Step 3: Spot-prime. Any areas of bare plaster exposed by sanding or where the original mist coat has failed should be spot-primed with a diluted emulsion (one part water to three parts paint) or a proprietary plaster primer.

Step 4: Clean. Wipe all surfaces with a damp cloth to remove sanding dust. Allow to dry completely.

Choosing Better Paint

The single most impactful upgrade you can make is to replace the developer's contract emulsion with a high-quality paint. The difference in appearance, durability, and feel is dramatic.

For walls and ceilings, the following products represent a significant step up from contract matt:

Dulux Trade Diamond Matt is the professional standard for durable matt emulsion. It is scrubbable, stain-resistant, and maintains its appearance in high-traffic areas. It is available in thousands of colours and offers exceptional value for money at the professional tier.

Little Greene Intelligent Matt Emulsion is a premium option that combines a beautiful flat matt finish with impressive durability and washability. It is available in Little Greene's full colour range and is particularly popular for living rooms, bedrooms, and reception areas where aesthetic quality is the priority.

Farrow & Ball Modern Emulsion offers the distinctive Farrow & Ball depth of colour in a wipeable, more durable formulation than their traditional Estate Emulsion. It is ideal for homeowners who want the Farrow & Ball look with better practical performance.

Benjamin Moore Regal Select is an American brand that has gained a strong following in London for its exceptional coverage, durability, and colour accuracy. It is a premium product that justifies its price through genuinely superior performance.

For woodwork (skirting boards, architraves, door frames, and doors), upgrading from the developer's standard vinyl satin to a premium product makes a noticeable difference:

Little Greene Intelligent Eggshell provides a subtle, sophisticated sheen with excellent durability. It is water-based, low-odour, and dries to a tough, wipeable finish.

Dulux Trade Diamond Satinwood is a hard-wearing, water-based satinwood that resists yellowing and is easy to clean. It is an excellent all-round choice for woodwork in apartments.

Farrow & Ball Modern Eggshell offers the Farrow & Ball colour range in a more durable eggshell finish for woodwork.

Colour Choices for New-Build Apartments

New-build apartments tend to be painted in a single neutral colour throughout, usually a flat white or magnolia. While this creates a blank canvas, it does nothing to enhance the space.

Consider introducing subtle variation between rooms. A warm white such as Little Greene's Slaked Lime or Farrow & Ball's Pointing in the living area, a cooler white like Little Greene's Gauze or Farrow & Ball's All White in bedrooms, and a deeper accent colour on a feature wall or in an entrance hall can add character and dimension without overwhelming a compact space.

Dark colours can work beautifully in new-build apartments, contrary to popular belief. A rich, deep colour on one wall of a living room or in a hallway can add drama and sophistication. Little Greene's Basalt, Farrow & Ball's Hague Blue, or Dulux's Sapphire Salute are all excellent choices for creating impact in a modern apartment.

Ceilings

Developer ceiling finishes are frequently the worst in the property. Ceilings are hard to paint well, they show every imperfection in the light, and they are the last thing to be painted on a tight programme. Roller marks, misses, and uneven coverage are common.

When repainting ceilings, use a high-quality matt emulsion applied with a good-quality roller sleeve (a medium-pile microfibre sleeve gives the smoothest finish). Work in consistent, parallel passes, maintaining a wet edge to avoid lap marks. Two coats are the minimum for an even, opaque finish.

A brilliant white ceiling can look harsh in a room with warm-toned walls. Consider using a very subtle off-white such as Farrow & Ball's All White or Little Greene's Loft White, which softens the contrast and creates a more cohesive feel.

Professional Repainting

While repainting a new-build apartment is technically straightforward, achieving a truly excellent finish requires skill, patience, and the right equipment. The smooth, flat surfaces of a new-build apartment show every imperfection in the paintwork, and poor cutting in, roller marks, or uneven coverage will be just as visible in premium paint as in contract emulsion.

Our interior painting service includes a full assessment of the existing finishes, thorough preparation including crack filling and sanding, and a complete paint system using the client's choice of premium paint. We work across London's new-build developments, from the riverside apartments of Battersea and Fulham to the townhouses of Pimlico and Westminster, and we understand the specific requirements and challenges of working in new-build properties.

For clients who have recently purchased a new-build apartment and want to elevate the finish to match the premium they have paid, a professional redecoration is one of the most cost-effective improvements available. The transformation from contract matt to a properly applied premium paint is immediately visible and makes the difference between a property that feels like a building site hand-over and one that feels like a finished home.

Timing and Practicalities

Living In During Decoration

Most apartment redecorations can be carried out while you are living in the property. A room-by-room approach allows you to continue using the apartment with minimal disruption. Each room typically takes one to two days to complete, depending on size and complexity.

Furniture and Floor Protection

All furniture will need to be moved away from the walls or to the centre of the room. Floors should be fully protected with dust sheets. In new-build apartments with engineered timber or tile flooring, this is particularly important, as paint splashes on hard flooring are difficult to remove without risking damage to the surface.

Drying and Ventilation

Modern water-based paints dry quickly, typically touch-dry in one to two hours and recoatable in four hours. However, the paint continues to cure and harden over the following days. Adequate ventilation during and after painting speeds the drying process and helps dissipate any residual odour.

The Second-Year Touch-Up

As mentioned earlier, new-build properties continue to settle for twelve to eighteen months after completion. Even if you repaint within the first year, some additional hairline cracking may appear. A professional touch-up visit after the first winter of occupation can address any cracks that have opened up, leaving the paintwork looking perfect going forward.

A well-painted new-build apartment, finished with quality materials and proper technique, is a fundamentally more pleasant place to live than one wearing its developer finish. It is an investment that you see and feel every day, and one that adds genuine value to your property.
