BSCO ANTI-CARBONATION
BSCO ANTI-CARBONATION
Information
A high-performance, water-based acrylic coating designed to protect reinforced concrete and cementitious surfaces
Description
"BSCO Anti-Carbonation is a high-performance, water-based acrylic elastomeric coating designed to protect reinforced concrete and cementitious surfaces from carbon dioxide ingress, chloride ion attack, UV degradation, and moisture penetration.
It forms a breathable, durable, and flexible protective film providing excellent adhesion and long-term performance for structural and architectural concrete elements. Available in white and other custom shades.
"
Fields of Application
✓ Structural & architectural protection for bridges, tunnels, and retaining walls
✓ Suitable for parking garages and exposed concrete
✓ Ideal for façades, balconies, and industrial & commercial buildings
✓ Applicable on concrete, stucco, render, cement plaster, and blockwork
✓ Can be applied on primed wood or metal with proper surface preparation
Advantages
✓ High CO₂ resistance (high-performance)
✓ Flexible, crack-bridging film
✓ Breathable with low water absorption. with Strong adhesion to concrete
✓ UV-resistant, maintains color
✓ Durable, washable surface & Water-based, low VOC
Application
BSCO ANTI-CARBONATION
- Substrate must be clean, dry, and structurally sound
- Free from dust, oil, laitance, loose particles, and previous flaking coatings
- Surface may be cleaned using grinding, brushing, or pressure washing
- Moist surfaces must be allowed to dry completely
- Prime porous substrates with BSCO Primer before application
- Use BSCO Putty 100/200 to fill minor cracks or uneven surfaces
- Minimum substrate tensile strength: 1.0 MPa
- Surface moisture content: <5%
Mixing
✓ Product is ready to use — stir thoroughly before application
✓ Dilute with clean water only if required:
– First coat: 10–15%
– Second coat: 5–10%
✓ Avoid over-dilution — weakens CO₂ barrier and reduces DFT
Application
✓ Apply with roller, brush, or airless spray
✓ Two coats are recommended — allow minimum 4 hours drying between coats
✓ Target DFT: 150–200 µm over 2 coats
✓ Ensure uniform film and consistent coverage (8–10 m²/kg per coat)
✓ Avoid application during rain, fog, or relative humidity >80%
✓ Do not apply at surface temperatures below +5°C or above +40°C
✓ Protect freshly applied coating from rain for minimum 4 hours
Cleaning
Clean tools and equipment immediately using clean water. Dried or cured material must be removed mechanically.
