Cure Hard 
Sodium silicate cure & dustproofer
Cure Hard is a clear, water-based, spray applied concrete cure, hardener and dustproofer. Cure Hard deeply penetrates concrete surfaces to densify, seal, harden and dustproof concrete and Portland cement-based material surfaces to help them achieve maximum abrasion resistance and without altering the natural appearance of the concrete. May contribute to LEED credits.
- Economical and Ready-to-Use: Convenient for immediate application.
- Preserves Appearance: Does not alter the natural color of concrete or aggregate.
- Safe and Environmentally Friendly: Non-flammable, odorless, and has an actual VOC content of 0g/l.
- Protective: Helps seal concrete against acids, oils, greases, salts, and tire marks.
- Compatible: Does not inhibit the adhesion of secondary toppings, adhesives, or coatings intended for concrete.
Application
- 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.
