🏠Applications
Why Choose This Product Line?
High-performance alkali resistance
Deeply seals free alkalis in the wall, effectively preventing salt efflorescence and salt deposits.
Enhanced adhesion
Builds a strong bridge between the surface and the coating, significantly improving adhesion and coating lifespan.
Surface consolidation
Transparent primer penetrates and rebinds loose, powdery layers, restoring solidity to old, friable surfaces.
System compatibility
Specialized primers are developed for interior, exterior, mineral, stone-effect, and other coating systems, coordinating seamlessly.
Environmentally friendly water-based
Low-VOC water-based formulation with mild scent for greener, safer application.

🏭Production Process
- ▸Uses acrylic copolymer emulsion as the main binder, combined with lead-free pigments and functional additives, with an alkali-resistant sealing formula tailored for each coating system
- ▸Clear primer is specially designed for mildly chalky surfaces; with strong penetration, it soaks into loose layers and binds loose particles into a stable surface
- ▸Mineral system primer developed for mineral paint systems, compatible with silicate coatings and improves chalking and friability of the surface
- ▸Sandable primer balances alkali-resistant sealing and enhanced adhesion, especially suitable for thick paste finishes like textured paint and stone effect paint
- ▸Each batch is tested for volume solids, alkali resistance, and adhesion before shipment, ensuring system compatibility and long-lasting performance with the top coat
🏆Quality Certifications
- ✓Complies with relevant national standards for limits of hazardous substances in architectural coatings, such as GB 18582-2020
- ✓China Environmental Label (十环) / environmentally friendly water-based formula with low VOC
- ✓AkzoNobel global quality system + ISO 9001 / ISO 14001 quality and environmental management systems
- ✓Provides technical data on alkali resistance and adhesion corresponding to each coating system
- ✓Provide product technical data sheets and warranty commitment; test reports available for project supply
🔧Installation Guide
- 1.Surface inspection: ensure the wall is clean, dry, and sound; remove loose dust, grease, and peeling areas; pretreat heavily chalked surfaces with a clear primer
- 2.Stir and dilute: stir thoroughly before use and dilute with an appropriate amount of water according to product instructions; do not exceed the recommended ratio to avoid reducing sealing performance
- 3.Apply evenly: apply a full coat using brush, roller, conventional spray, or airless spray; ensure no missed spots, no pooling, and complete coverage
- 4.Alkali sealing: focus on sealing areas with high alkalinity or susceptibility to salt efflorescence; apply additional local coats where needed to ensure thorough alkali sealing
- 5.Recoat transition: when the primer reaches its recoat window, apply the corresponding topcoat to ensure system adhesion and overall durability
🧽Care & Cleaning
After applying primer, follow the specified recoat time (typically 1-3 hours, depending on product and temperature/humidity) before applying top coat to avoid peeling.
After opening, use immediately and keep the lid tightly closed to prevent skinning, moisture absorption, and contamination that may affect film formation.
After applying water-based primer, immediately wash brushes, rollers, and spray guns with clean water to prevent hardened residue that is difficult to remove.
Select the correct grade for different surface issues such as chalking, salt efflorescence, and moisture to ensure effective sealing and adhesion.
📦Packaging & Shipping
