Liquid Sealer Hardener for Concrete Pavement

Penetrating: This is a clear, transparent liquid that penetrates deep into the pores of the concrete and reacts chemically with the substances therein.

Chemical Reaction: They react with free calcium ions in the concrete to form hydrated calcium silicate, which fills the pores and creates a solid sealing layer.

Environmental Friendliness: Most concrete sealers and hardeners are non-toxic, non-flammable water-based materials, minimizing environmental impact.

Performance Improvement: Treated concrete surfaces become harder, reducing dust generation and improving resistance to wear, chemical attack, and freeze-thaw cycles.

Ease of Maintenance: Surfaces treated with these products are easier to clean and maintain, requiring only regular sweeping and mopping with water.

Aesthetics: Treated surfaces can develop a natural sheen; some products, when combined with polishing techniques, can achieve a mirror-like finish, enhancing the visual appeal of the space.

The working principle of concrete sealers and hardeners is based on their chemical reaction with calcium ions within the concrete, forming hydrated calcium silicate gels. These gels crystallize within the concrete, increasing its density and hardness. The chemical reactions also effectively seal the surface pores, preventing the penetration of water, oils, and other contaminants, reducing maintenance costs and extending the service life of the concrete.

Before application, the surface must be clean and dry, with all loose particles, oils, and contaminants removed. The sealer hardener is then evenly sprayed or applied to allow for adequate penetration. In some cases, multiple applications may be required for optimal results. Mechanical grinding and polishing can further enhance the gloss and surface flatness, resulting in a marble-like sheen that improves with use over time.

Concrete sealers and hardeners have a wide range of applications suitable for areas requiring wear resistance and impermeability, such as factory floors, logistics centers, underground parking garages, large supermarkets, sports centers, and more. They are also used for new and old terrazzo and hardened wear-resistant flooring, as well as old concrete surfaces prone to dusting and spalling, and new surfaces like trowel-finished concrete, wear-resistant flooring, and terrazzo.
