LITHIUM HARDENER (LH) is a specialty mixed/hybrid silicate that combines the deep-penetrating power of Lithium with the excellent surface-filling properties of Potassium. This "Dual-Action" formula is specifically engineered for surfaces that require both internal densification and surface reinforcement.
Why Choose a CETEX LITHIUM HARDENER?
- Enhanced Pore Filling: While Lithium penetrates deep, the Potassium component helps bridge larger pores in older or more "open" concrete slabs.
- Cost-Effective Performance: It offers a significant performance upgrade over pure Potassium or Sodium silicates while remaining more budget-friendly than pure Lithium Silicate.
- Reduced Efflorescence: The inclusion of Lithium stabilizes the Potassium, significantly reducing the risk of "white blooming" compared to standard Potassium-only products.
- Improved Water Retention: Excellent for use in coatings and mortars where controlled drying and water resistance are critical.
Key Applications
- Restoration of Old Concrete: The ideal choice for "soft" or aging concrete floors that need a high volume of silicate to regain structural integrity.
- Industrial Primers: Used as a binder in high-performance coatings to improve adhesion to mineral substrates.
- Grind & Seal Projects: Provides a solid foundation for the mechanical polishing process, especially in the initial stages of grinding.
- Masonry Water-Repellents: Used to treat brick and stone to prevent moisture ingress while allowing the material to "breathe."
