Silicate Application
Sanlee High-Performance Concrete Sealer
Sanlee concrete sealer is a professional penetrating concrete densifier built with advanced silicate densification technology.
Different from traditional surface coating sealers, this high-performance concrete sealer penetrates deep into concrete interiors to trigger permanent chemical densification.
It forms a breathable, waterproof, wear-resistant and anti-corrosion protective film on concrete substrates, providing long-term reinforcement and surface protection for all new and old concrete structures in industrial and commercial scenarios.
Concrete Sealer Features & Working Principle
Our water-based concrete sealer features an eco-friendly, zero-volatile formula with high construction safety.
As a premium concrete densifier, its active silicate molecules penetrate concrete capillaries and react with cement calcium hydroxide to form stable insoluble silicate crystals, thoroughly blocking internal pores.
This process greatly enhances concrete density, hardness and impermeability, resisting water erosion, surface dusting, weathering and chemical corrosion while retaining concrete air permeability, ensuring long-lasting floor protection.
Core Application Scenarios
This industrial concrete sealer suits a wide range of application scenarios, including factory floors, warehouse concrete grounds, commercial mall floors, municipal roads, parking lots and building concrete walls.
It efficiently solves common concrete problems like dusting, sanding, low hardness and water leakage, effectively extending the service life of concrete structures and cutting long-term maintenance costs for industrial and construction projects.
