Frequently Asked Questions

Common questions about mineral finishes, expectations, and our process.

Finish Expectations

Will my wall look exactly like the photos?

No. Mineral and decorative finishes are hand-applied materials. While reference images guide tone and texture, each wall reacts differently to light, substrate, and application. Variation is inherent and intentional.

Are uneven tones or marks considered defects?

No. Movement, tonal shifts, and visible strokes are part of the character of mineral finishes and are not classified as defects.

Can I request a perfectly uniform finish?

Mineral finishes are not suitable for clients expecting flat, uniform colour. If uniformity is a priority, we will recommend alternative systems.

Material & System Questions

Do you use specific brands (e.g. Novacolor, etc.)?

We work with multiple mineral and decorative systems. Materials are specified based on surface condition, environment, and desired outcome rather than brand preference.

Can I choose the exact material beforehand?

Final material selection is confirmed after surface evaluation to ensure compatibility and durability.

Are these finishes eco-friendly?

Most mineral systems are breathable and low-VOC. Suitability depends on application area and substrate.

Do you do 'normal' painting?

We do not provide 'standard' or budget painting. We execute Architectural Paint Systems. This includes moisture assessment, substrate-specific priming, and multi-layer execution. If you are seeking a 'cheap lick of paint' without technical oversight, our services are not a match.

Surface System Specifics

Lime Paint: Will the colour be 100% solid?

No. Lime Paint is a mineral finish that creates 'clouding' or tonal movement. If you want a perfectly flat, plastic-look solid colour, you should choose a standard acrylic paint (which we do not prioritize).

Lime Plaster: Are the texture marks flaws?

No. Hand-applied plaster marks are the intentional signature of the artisan. We do not provide 'machine-smooth' mineral plaster. If you desire zero texture, this system is not for you.

Microcement: Is it indestructible?

No. While highly durable, microcement can crack if the building structure moves or if heavy objects are dropped. It is a premium skin, not a structural reinforcement.

Liquid Metal: Why is the colour changing?

Liquid metal contains real metal particles that will oxidise and patina over time. This is a natural reaction to the environment and is considered a feature, not a defect.

Patina & Oxidised: Can you control the exact rust pattern?

No. Reactive finishes are inherently unpredictable. We guide the direction, but the final pattern is a result of material behaviour. No two walls will ever be the same.

Industrial Epoxy: Will it look like a decorative floor?

Our industrial systems prioritize function over decoration. While they look clean and professional, they are specified for chemical and abrasion resistance, not as a decorative 'showroom' finish.

Waterproofing: Does it fix existing structural leaks?

No. Waterproofing systems prevent surface penetration; they do not fix cracked pipes or structural slab failures. Structural issues must be resolved by a specialist before our application.

Custom Murals: Can I change the design on-site?

No. Designs are locked in during the mock-up phase. Any on-site changes to approved graphics will halt production and be fully chargeable as a new project scope.

Process & Site Conditions

Do you need to visit the site before confirming?

Yes. Certain finishes require onsite evaluation to assess wall condition, moisture, and preparation requirements.

What preparation work is included?

Preparation is specified per project and may include surface repair, priming, sealing, or leveling depending on the chosen system.

Will furniture and flooring be protected?

Yes. We protect adjacent surfaces as part of our standard process. Clients are advised to clear small items where possible.

Policies & Liability

What is your refund policy?

Mineral and decorative surface systems are bespoke, hand-applied works. Once the application process begins (surface preparation or material mixing), the project is strictly non-refundable. Cancellations after material procurement but before application will incur a restocking and administrative fee.

Are you liable for failures caused by the building?

No. Plain Work is not liable for failures caused by structural defects, water ingress from window frames, rising damp from slabs, or leaking pipes discovered after our initial assessment. Surface systems are finishes, not structural waterproofing repairs.

What happens if I change my mind about the texture?

Texture and tonal movement are agreed upon during the sampling/mock-up phase. If the client requests a change after application has started, this is classified as a change in scope and will be fully chargeable at current rates.

Touch-ups & Maintenance

Do you provide free touch-ups?

Only for application-related defects identified during the final site handover. Any damage caused after handover by furniture movement, other contractors (e.g. electrical/plumbing), cleaning chemicals, or general wear is strictly chargeable.

Can a single spot be patched perfectly?

Mineral finishes are seamless. Small patches may remain visible due to the hand-applied nature of the material. To achieve a perfectly seamless result after damage, we may recommend re-coating the entire wall from corner to corner at the client's expense.

Humidity, Air-Conditioning & Sealers

Humidity

Are Lime Paint and mineral finishes suitable for Singapore's humidity?

Yes, when specified and applied correctly. Lime-based finishes are naturally breathable and allow moisture to pass through rather than trap it behind the wall.

Will humidity cause mould or peeling?

Breathable finishes reduce the risk of trapped moisture, but no wall finish can compensate for ongoing water ingress, leaks, or persistently damp substrates. Surface condition and environment must be assessed before application.

Can mineral finishes be applied to previously painted walls?

Possibly. Existing coatings, moisture levels, and wall condition must be evaluated. In some cases, additional preparation or sealing is required to ensure compatibility.

Air-Conditioning

Does air-conditioning affect mineral finishes?

Yes. Frequent temperature changes and prolonged air-conditioning can influence drying behaviour and visual appearance, particularly during the curing period.

Should air-conditioning be turned off during application?

We may recommend limiting air-conditioning during application and initial curing to allow the finish to set evenly. Specific guidance will be provided per project.

Will air-conditioning damage the finish long term?

Once fully cured, mineral finishes perform well in air-conditioned spaces. However, extreme temperature cycling may accentuate natural tonal variation over time.

Sealers

Do mineral finishes require a sealer?

Some systems may require sealing depending on location, usage, and exposure. Sealers are specified only when necessary to balance protection and breathability.

Will sealing change the appearance of the finish?

Yes. Sealers may slightly deepen colour, reduce porosity, or alter sheen. This is considered part of the finish specification, not a defect.

Can I choose not to use a sealer?

In certain applications, an unsealed finish may be acceptable. However, omitting a recommended sealer may affect durability and maintenance expectations.

Are sealed mineral finishes waterproof?

Sealers provide resistance, not complete waterproofing. Mineral finishes are not intended to replace waterproofing systems.

Environmental conditions such as humidity, temperature, and air-conditioning influence mineral finishes and are considered during specification.

Suitability Filter

Who is Plain Work NOT suitable for?

Our systems are not suitable for clients expecting plastic-like uniformity, zero natural variation, or those looking for the cheapest possible quote regardless of environment. We specialize in high-performance, artisanal surface systems for informed clients.

Do you accept "unlimited" revisions?

No. Visual outcomes are locked in via approved samples. On-site "trial and error" during application is not permitted and will incur additional system costs.
