Nano Antibacterial Interior Paint — Interior Wall Protection with Long-Lasting Antimicrobial Defense
Nano Antibacterial Interior Paint is made from nano-silver (Ag+) technology that penetrates bacterial cell membranes and denatures internal protease to stop microbial development. It is a water-based coating, has no APEO and ultra-low VOC emission, and has 26 years expertise in coating manufacture. It has a contrast rate of > 0.95 and a scrub resistance of > 20,000 cycles. Standard coverage is 0.2-0.25kg/㎡ for two finish coats, offering complete thousand-color customisation to meet the design needs of varied interior projects.
What Sets This Antibacterial Paint Apart
Germs and mould can develop even with regular interior paints, which provide a physical barrier alone and do not offer any antimicrobial protection. The Nano Antibacterial Interior Paint comprises 10-50 nm nano-silver particles evenly distributed in the cured layer and provides long-lasting active protection.
These particles operate on the structure and metabolism of bacterial cells and kill over 99.9% of common bacteria, moulds and fungus.
Standard biocide coatings have actives that volatise and fail. The nano-silver is securely bound in the resin matrix. Daily washing and light abrasion reveal new active particles and preserve antibacterial activity over the service life of the coating.
Key Performance Specifications
Nano-silver Antibacterial – Inhibits microbial reproduction and destroys bacterial cell structures at nanometre level for long-lasting wall hygiene.
APEO Free, super low VOC — Suitable for long term inhabited spaces: homes, schools, medical rooms.
Excellent scrub resistance - 20,000+ cycles per ASTM D2486, maintains film and appearance after repeated washing.
Stable concealing power – Contrast ratio > 0.95, covering base colours and minor defects.
Low odour – No strong odour during or after construction; quick occupation.
Flexible colour customisation Thousand colour matching for varied styles and demands of projects.

Complete Three-Layer Coating System
Full performance requires full three-layer sequential construction. If you skip a layer, you compromise the wall’s defence.
Layer 1 – Putty: 2-3 coats 1.2-2.5 kg/㎡. Levels walls, creating a flat even surface. Dilute with 35%-40% clean water.
Layer 2 – Primer: 1 coat 0.13-0.15 kg/㎡ Seals pores, isolates alkali, improves adhesion Add ~10% clean water.
Layer 3 – Antibacterial Finish: 2 coats 0.2–0.25 kg/㎡ total. Contains nano-silver antibacterial compound. Dilute with 10%-15% clean water. Compatible with brush, roller or spray.
Before Installation: Wall foundation cured minimum 21 days, pH below 10, moisture not over 10%.
Application Environments
Residential Spaces – Kitchens, baths, and children’s rooms; prevents mould and bacteria growth in humid situations
Schools & Kindergartens – Classrooms and activity spaces require regular cleaning. Cycle scrub resistance of 20,000+ keeps walls clean during everyday cleaning.
Hotels & Office Buildings – Meets tidy decorating & surface hygiene needs for guest rooms, lobbies and hallways. The colours may be customised to the design styles.
Healthcare & Public Facilities – Hospital waiting rooms, corridors and treatment rooms are clean immediately after cleaning.
Food Processing Spaces – It prevents the growth of microbes on damp condensing walls fulfilling hygienic standards for food processing and storage.

Frequently Asked Questions
Q1: Is antibacterial action weakened by cleaning?
A1: No. Cleaning merely eliminates surface dust. New active components are exposed, providing continuing protection.
Q2: Dilution and consumption in the standard way?
A2: Putty: Water content 35%~40%, 1.2~2.5 kg/㎡, 2~3 times. Primer : Water ~ 10% , 0.13-0.15 kg/㎡ , 1 coat. Finish: 10-15% water, 0.2-0.25 kg/㎡, 2 coats. Humidity under 85% at above 5° C.
Q3: How is it constructed?
A3: Brush, roller, spray. Follow putty-primer-finish sequence, manage dilution, check wall base for moisture and pH.
Q4: How does it differ from normal anti-mold paint?
A4: Conventional paints contain surface fungicides that evaporate. Nano-silver is included in the formula so that each time you put on the film, fresh active elements are exposed.
Q5: Is the cured film suitable for indoor use?
A5: Nano-silver is encased in resin, no free precipitation. Occupied Space Ultra Low VOC, APEO-Free Formulation
