Cure Hard Sodium Silicate Cure & Dustproofer

Cure Hard is a clear, water-based concrete cure, hardener, and dustproofer that deeply penetrates for maximum abrasion resistance

Cure Hard densifies, seals, hardens, and dustproofs concrete and Portland cement-based surfaces without altering the natural color of the concrete or aggregate. It may contribute to LEED credits.

Key Features & Benefits

• Does not alter the natural color of concrete or aggregate
• Non-flammable, odorless, 0 g/L actual VOC content
• Helps seal against acids, oils, greases, salts, and tire marks
• Does not inhibit adhesion of secondary toppings, adhesives, or coatings

Application Instructions

• Surface Preparation: Apply to clean, structurally sound surfaces free of water, laitance, and contaminants. For aged concrete, ensure surfaces are free of dirt and dry to maximize penetration.
• Coverage Rates:
  • Hard Troweled Finish: 300-500 sq ft/gal
  • Broom or Float Finish: 200-400 sq ft/gal
  • Rough Finish: 200-300 sq ft/gal
  • Aged Concrete: 200-300 sq ft/gal
  • Vertical Surfaces: 200-300 sq ft/gal
• Application: Can be applied with a sprayer, brush, or roller, immediately after final finishing operations once bleed water has receded. Ensure the surface does not pond or puddle. Use in temperatures from 40°F to 100°F.
• Additional Applications: Apply immediately or up to 24 hours before installation of underlayment toppings. Reapply if exceeding 24 hours or if the continuous film is compromised.
