LithSeal Lite

Low-solids lithium silicate concrete sealer/densifier

LithSeal Lite is an economical lithium-silicate sealer, densifier, and hardener designed for concrete surfaces. It deeply penetrates cured concrete, reacting to form a calcium silicate hydrate that enhances the concrete’s properties. Treated surfaces will be more resistant to abrasion, less porous, and better protected against dusting and water permeability, while maintaining a breathable quality and the concrete’s natural appearance.

  • Economical and Ready-to-Use: Simplifies application processes without additional preparation.
  • Enhanced Surface Quality: Reduces porosity and dusting, increases abrasion resistance, and does not alter the natural color of the concrete.
  • Environmental Benefits: Contributes to potential LEED credits, VOC content is 0 g/l, making it an environmentally friendly choice.
  • Versatility: Suitable for both new and existing concrete surfaces.
  • User-Friendly Application: Can be applied with a low-pressure sprayer, followed by spreading with a soft broom or microfiber applicator to ensure even coverage.

Application

  • Surface Preparation: Apply only to clean surfaces free of cures, bond breakers, oil, dirt, and debris. For existing concrete, clean with SpecChem products like Orange Peel or Berry Clean, neutralize, and thoroughly rinse.
  • Application Rates:
    • Fresh Concrete: 500-800 sq ft/gal
    • Existing Concrete: 250-700 sq ft/gal, depending on the finish
  • Drying Time: Typically 1-2 hours, allowing for quick return to service.
  • Application Conditions: Apply in temperatures from 40°F to 100°F.

Final Finishing

  • Maintenance: Regular maintenance increases hardness, durability, and sheen.
  • Buffing Recommendations: Use an orbital floor machine or high-speed propane burnishing machine with appropriate pads to enhance sheen and gloss.
