High-Performance 1K Polyurethane Primer for Concrete & Ceramic Flooring

The ZDS-1901 1K Polyurethane Primer is expertly engineered for optimal substrate penetration and adhesion, primarily designed for use on concrete and ceramic floors. Its advanced formulation allows the primer to deeply penetrate, fill, and seal the micro-pores within concrete and mortar substrates, significantly reducing voiding, resin wastage, and the risk of delamination in subsequent stone, carpet, or resin flooring systems. The light yellow color aids in even application, ensuring effective coverage and uniformity across industrial, warehousing, commercial, and residential floors. This product is particularly suited for garage floors, warehouses, and light industrial environments where superior base adhesion is vital for the longevity of resin coating and decorative finishes.

Key Properties & Benefits

  • Outstanding substrate sealing capabilities that minimizes absorption and resin loss.
  • Enhances adhesion for subsequent coatings or toppings.
  • Single component (1K) for simplified handling and application, requiring no on-site mixing.
  • Chemically engineered to decrease the occurrence of voids and pinholes.
  • Suitable for both new construction and refurbishment projects.
  • Durable performance for indoor and certain protected outdoor settings.

Areas of Application

  • Garage floors in residential or commercial properties
  • Warehouses and light industrial facilities
  • Offices, retail stores, restaurants, and hotels
  • Ceramic and concrete walkways, terraces (with UV-stable formulations)
  • Sports fields, repair shops, and light-to-medium traffic areas

Performance You Can Trust

ZDS-1901 ensures a robust foundation for any floor finishing system, granting peace of mind with its proven track record across various industries, including manufacturing, logistics, construction, decoration, and medical facilities. Its long open time allows for practical on-site adjustment and ease of use, while its cured state provides excellent hardness and chemical resistance typical of premium polyurethane technology.

💡 Use Cases

Ensure the substrate is clean, dry, and free of dust, oil, or contaminants. Stir the ZDS-1901 primer thoroughly before use. Using a roller or brush, apply a uniform coat onto the prepared surface and allow it to fully penetrate. Avoid puddling. Let the primer cure for 24 hours at 25°C before applying subsequent coatings or overlays. For best results, maintain adequate ventilation and ambient temperature during application and curing.

  • Garage floors (residential & commercial)
  • Warehouses & workshops with light-to-medium loads
  • Indoor office, restaurant, and hotel floors
  • Ceramic or concrete terraces and walkways
  • Sports fields and retail stores
  • Areas requiring reliable adhesion and substrate sealing

Available in sealed containers. Store in a dry, cool area away from direct sunlight. Shelf life is typically 12 months in unopened packaging.
