Nippon Paint Aqua Epoxy Primer  Two-Component Water-Based Epoxy Sealer for Concrete Floors & Tiles

Product Overview

Nippon Paint Aqua Epoxy Primer is a premium two-pack waterborne epoxy primer formulated with modified amine curing agents. It is engineered to provide superior substrate penetration and exceptional adhesion to concrete floor surfaces, plastered walls, and even ceramic tiles.

As a high-performance eco-friendly primer, it is the ideal foundation for areas requiring a low-odour and low-VOC environment, such as hospitals, schools, pharmaceutical factories, and residential kitchens or bathrooms. It acts as an essential "tie coat" between the masonry substrate and water-based topcoats (like Nippon Aqua Epoxy), ensuring a tough, abrasion-resistant finish that prevents peeling and flaking under light to medium loads.

Application System

1. Sealer/Primer (1 Coat): Nippon Paint Aqua Epoxy Primer.

2. Topcoat (2 Coats): Nippon Paint Aqua Epoxy.

Surface Preparation

• Concrete Floors: Must be cured for at least 28 days. For best results, acid etching or light mechanical grinding is recommended to remove laitance and ensure maximum adhesion.

• Moisture Content: Must be below 14% (measured by protimeter).
•       Alkalinity: pH level should be below 8 or 9.
•       Condition: Surface must be clean, dry, and free from oil, grease, and old loose paint. Repair cracks using a suitable epoxy filler before priming
