Cure & Seal WB 30 Green Conscious Product

ASTM C309 compliant 30% solids water-based cure & seal

Cure & Seal WB 30 is a high solids, water-based, VOC compliant acrylic polymer engineered to cure, seal, harden, and dustproof freshly placed concrete, and improve the wearability and durability of aged concrete surfaces. This low-odor, water-based formulation is ideal for both interior and exterior applications.

  • Provides a tough, glossy film that resists abrasion and common staining materials.
  • Prevents adhesion of cementitious droppings and penetration of most oils and greases.
  • Reduces maintenance and cleanup costs while brightening floors.
  • Allows recoating prior to occupancy without stripping previous applications, enhancing the final glossy finish.
  • USDA accepted and meets strict environmental standards, including VOC emission requirements of SCAQMD.

Safety Sheet


  • New Concrete: Apply once surface water has disappeared, ensuring the concrete surface is not marred by walking. Apply in a uniform coat and consider a second coat at 400 sq ft/gal for enhanced curing and sealing protection.
  • Existing Concrete: Ensure the surface is clean, dry or damp, and free of stains, oil, grease, and incompatible coatings. Treatment revitalizes concrete, brick, or terrazzo floors, making them brighter and easier to maintain.
  • Coverage:
    • Curing: 300 sq ft/gal.
    • Dustproofing and Sealing: 300 – 500 sq ft/gal.
    • Aged concrete: 400 – 600 sq ft/gal.


Available in 275-gallon totes, 55-gallon drums, and 5-gallon pails.
