How does antiviral paint differ from standard interior paint?

Antiviral wall paint incorporates copper-ion (Cu²⁺) particles into the paint formulation. Once applied, the surface continuously releases trace copper ions that disrupt viral and bacterial cell membranes on contact — the same principle behind copper's long-recognized antimicrobial properties, now built into an ordinary wall coating.

What does ISO 21702 measure?

ISO 21702 is the international standard for measuring antiviral activity on plastics and other non-porous surfaces. The test places a defined virus inoculum on the test surface, incubates it for a set contact time, then recovers and quantifies surviving virus. A 99.4% reduction in 30 minutes means fewer than 6 in every 1,000 viral particles survived the contact period.

Is it safe for occupied rooms?

The antiviral effect is delivered by copper ions incorporated into the dry paint film, not by volatile chemicals. Contact DEMORE for the full technical data sheet and VOC certification for your target market before specifying.

Application is the same as standard interior wall paint — roller, brush, or spray. No special tools or training are required. Request the technical data sheet for surface preparation, coverage rate, and dry times.

Antiviral Interior Wall Paint

Q: How long does the antiviral effect last?

The copper-ion additive is integral to the paint film, not a topcoat treatment that washes off. Duration data is included in the manufacturer's technical dossier, available through DEMORE on request.

A wall coating that fights back. Copper-ion (Cu²⁺) technology built into standard interior paint delivers a 99.4% reduction in COVID-19 virus on the painted surface in just 30 minutes — verified by third-party ISO 21702 testing. Applied exactly like any other interior paint. Designed and manufactured in Korea, sourced for global buyers through DEMORE.

01 · Overview

Walls that actively reduce the virus load in a room.

Pathogens land on surfaces. They stay viable. People touch those surfaces. This is the contact-transmission problem that hand hygiene alone cannot solve — because hands cannot wash the wall.

Antiviral wall paint addresses the surface itself. Copper-ion (Cu²⁺) particles incorporated into the paint formulation give the dried surface a continuous, passive antiviral property. No activation required. No maintenance. No additional product. The wall simply works.

The effect is validated under ISO 21702, the international standard for antiviral activity on non-porous surfaces. A third-party laboratory confirmed 99.4% COVID-19 virus reduction in 30 minutes of contact time. The product is designed and manufactured in Korea by a specialist coatings producer and sourced for global buyers through DEMORE.

Applied wall surface — copper-ion antiviral coating

02 · Mechanism

Why copper kills viruses. And why it keeps working.

Copper's antimicrobial action is not chemical in the conventional sense — it is electrochemical, and it does not deplete in the way a disinfectant spray does.

Step 1 — Contact

Virus lands on surface

Airborne or hand-transferred viral particles come to rest on the painted wall surface. At this point the virus is viable — it retains the ability to infect a new host for hours on ordinary surfaces.

Step 2 — Ion release

Cu²⁺ attacks membranes

Copper ions (Cu²⁺) continuously released from the paint film interact with the viral envelope and protein capsid. The ions disrupt lipid membrane integrity and interfere with the nucleic acid inside — a multi-point attack that the virus cannot adapt to.

Step 3 — Inactivation

99.4% reduction in 30 min

ISO 21702 testing confirms 99.4% of COVID-19 viral particles are inactivated within 30 minutes of contact with the treated surface. The mechanism is passive — no UV, no heat, no manual activation required.

Paint film surface — Cu²⁺ ions integrated into the dried coating

Why copper ions rather than quaternary ammonium or silver? Copper is the best-documented antimicrobial metal: it has been studied in clinical environments since the early 2000s, its mechanism is understood at the molecular level, and it acts on a wider spectrum of pathogens than single-chemistry approaches.

Critically, copper ions are integral to the paint film. They are not a surface spray that wears off. Repainting is not required to maintain the antiviral property — the coating continues to release ions across the surface life of the paint.

03 · Performance

04 · Application

Apply it like any other interior paint. The wall does the rest.

No special tools. No specialist applicators. No changes to the painting process. Antiviral wall paint is applied by roller, brush, or spray exactly as a standard interior emulsion would be.

Preparation

Standard surface prep

Clean, dry, dust-free surface — the same preparation required for any quality interior paint. Priming recommendations are included in the manufacturer's technical data sheet.

Application

Roller, brush, or spray

Conventional application methods. No specialist equipment, no modified technique, no additional training for the painting crew. Coverage rate and number of coats are specified in the TDS — contact DEMORE to request it.

Result

Continuous antiviral surface

Once dry, the wall has a permanently active antiviral surface with no further intervention required. The copper-ion effect is built into the film — it does not require activation, reapplication, or recharging.

05 · Applications

Anywhere contact transmission is a risk.

A·01

Hospitals & clinics

Patient rooms, examination rooms, corridors — where pathogen load on touch surfaces is highest and infection control is critical.

A·02

Schools & kindergartens

High-density, high-touch environments where viral transmission between children is a persistent concern for operators and parents.

A·03

Hotels & hospitality

Guest rooms, lobbies, and high-turnover common areas where hygiene standards are both a guest expectation and a brand promise.

A·04

Office & corporate

Meeting rooms, breakout areas, lift lobbies — the surfaces that rotate daily contact between large numbers of staff.

A·05

Residential kitchens

Kitchen walls are high-touch and hard to keep chemically disinfected. Antiviral paint gives a passive hygiene layer without wet cleaning risk to surfaces.

A·06

Public restrooms

Walls in restroom cubicles and handwashing areas receive heavy contact; an antiviral surface reduces the resident pathogen load between cleaning cycles.

A·07

Transport hubs

Airport terminals, train stations, and transit interchanges where high footfall creates high contact-surface challenge.

A·08

Food production

Processing areas where wall-surface hygiene is subject to regulatory inspection and operational contamination-control protocols.

07 · FAQ

Buyer questions, answered.

How does this differ from ordinary interior paint?

Standard interior paint is passive — it covers and protects the surface. Antiviral wall paint contains copper-ion (Cu²⁺) particles that actively disrupt viruses on the surface. The application process is identical, but the dried film has a continuously active antiviral property that a standard paint does not.

What does ISO 21702 actually measure?

ISO 21702 is the international standard for testing antiviral activity on non-porous surfaces. A defined quantity of virus is deposited on the test surface, held for a set contact time, then recovered and titrated to measure how many viable viral particles remain. The 99.4% result means fewer than 6 in 1,000 COVID-19 viral particles survived 30 minutes of contact with the treated surface.

Is the paint safe for occupied rooms?

The antiviral activity comes from copper ions fixed within the dry paint film — not from a volatile or airborne compound. Contact DEMORE for the full technical data sheet and safety data sheet relevant to your target market and application before specifying.

How long does the antiviral effect last?

Because the copper-ion additive is integral to the paint film, not a topcoat treatment, the antiviral property does not diminish with routine cleaning the way a disinfectant spray would. The manufacturer's technical data sheet includes durability data. Request it through DEMORE.

What are the coverage rate and available colours?

Coverage rate, colour options, dry times, and VOC data are published in the manufacturer's technical data sheet. Contact DEMORE to request the TDS and a colour chart.
