Nippon Paint Hi-Bond Wall Sealer is a high-performance, water-based acrylic sealer specifically formulated for interior and exterior masonry surfaces. It is uniquely engineered to provide superior adhesion on challenging substrates, such as chalky old paint, powdery surfaces, and internal skim-coated walls. Its advanced formulation penetrates deep into the substrate to bind loose particles, creating a solid foundation for subsequent topcoats. This sealer is highly resistant to efflorescence and alkalinity, ensuring that the finish coat remains vibrant and free from peeling or flaking. It is an eco-friendly "Green Choice" product with low VOC and low odor.
Paint Type: Water-based (Acrylic)

Thinning: Ready for use. If necessary, dilute with maximum 5% clean water.
Touch Dry: 15 – 30 minutes (depending on temperature and humidity)
Hard Dry: 1 hour
Recoating Interval: Minimum 2 hours
Theoretical Coverage: 10 – 12 m² per litre per coat (Subject to surface porosity)
Shelf Life: Up to 36 months in a tightly sealed container
Mixing: Stir the sealer thoroughly with a clean paddle before use to ensure a uniform consistency.
Application Method: Apply using a high-quality Brush, Roller, or Conventional/Airless Spray.
Dilution: Ready for use. For highly absorbent or chalky surfaces, no thinning is recommended to ensure maximum binding strength.
Cleaning: Clean all tools and equipment with clean water immediately after use.
Note: Ensure the surface is completely dry before application. Do not apply during rain or high humidity (above 85%).
For New or Old Masonry Surfaces:
Sealer/Primer (1 Coat): Hi-Bond Wall Sealer.
Topcoat (2 Coats): Compatible with all Nippon Paint interior and exterior topcoats (e.g., Weatherbond, Odour-less AirCare, Satin Glo, or Vinilex).
General Cleaning: Surfaces must be structurally sound, dry, clean, and free from dirt, grease, oil, and loose matter.
Chalky/Powdery Surfaces: Remove as much loose material as possible using a high-pressure water jet or a stiff brush before sealing.
Moisture & Alkalinity: For new walls, allow a curing period of at least 28 days. Ensure moisture content is below 16% and alkalinity is below pH 9.
Biological Treatment: Treat areas affected by fungus or algae with Nippon Paint Fungicidal Wash and rinse thoroughly before application.
Repair: Fill cracks and surface defects with a suitable filler (e.g., EasySKIM 5000) and sand smooth before applying the sealer.
