Polished concrete floors in retail stores, corporate offices, airports, hotels, and industrial facilities across Southeast Asia, Europe, and Asia are not produced by grinding alone. The grinding and polishing process that creates a reflective, durable concrete surface depends on Lithium Silicate densifier applied at the correct stage in the polishing sequence to harden the concrete matrix, increase surface hardness, and enable the fine polishing grits to produce a high-gloss finish that resists wear over years of heavy foot and vehicle traffic. Without Lithium Silicate, polished concrete surfaces wear prematurely, lose gloss under traffic, and dust continuously from the weak surface layer exposed by grinding.

High Concentration Lithium Silicate, carrying CAS number 10102-24-6, is a lithium silicate solution with solid content above 25 to 30 percent, significantly higher than standard grade lithium silicate products at 15 to 20 percent solid content. The higher active silicate concentration per liter of product delivers more reactive material into the concrete pore structure per application, making it the correct specification for dense, hard, low-absorption concrete surfaces where standard concentration densifiers penetrate too slowly or deliver insufficient reactive silicate to achieve the target surface hardness improvement.

Lithium silicate is the preferred concrete densifier and floor hardener for polished concrete, industrial flooring and infrastructure. Expert guide to chemistry, grades, application and global sourcing.

Not all Lithium Silicate grades perform the same on concrete floors. This guide covers how to select the right solid content, silica-to-lithia ratio, and particle size for your specific application, whether you are treating new industrial floors, producing polished concrete, or hardening old dense substrates. Includes a grade comparison table and application rate guide. EastChem supplies Lithium Silicate CAS 10102-24-6 in standard and colloidal grades with full technical support.

If your concrete floor is dusting, cracking, absorbing water, or losing surface strength under traffic and load, you are not dealing with a cosmetic problem. You are dealing with a structural vulnerability that gets worse over time and more expensive to fix with every month you wait. Lithium Silicate is the chemical solution that addresses all three of these problems at once, permanently, from within the concrete itself.

Concrete floors are specified for their strength and durability. The reality on most construction sites is that the finished floor surface — the zone that actually contacts traffic, chemicals, and cleaning equipment — is significantly weaker than the concrete below it. This surface weakness is not a quality control failure. It is chemistry. And Lithium Silicate is the chemical solution.

Most concrete floor problems get treated with coatings. Epoxy, polyurethane, acrylic sealer — layer after layer applied over a surface that was never properly hardened in the first place. The coatings wear through. The floor dusts again. Another contractor is called, another coating is specified, and the cycle repeats every three to five years at significant cost. If this is your situation, the coating is not the problem. The surface is. And Lithium Silicate is the solution that addresses it permanently — from the inside out, not the surface down.

Concrete floors fail in predictable ways. Dusting under forklift traffic. Surface abrasion in high-footfall retail environments. Moisture vapor transmission causing adhesive failure under flooring finishes. In every case, the underlying cause is the same: a porous, under-dense surface layer that lacks the hardness and impermeability the application demands. Lithium silicate concrete densifier addresses all three failure modes through a single penetrating treatment — and unlike surface coatings, it does so permanently.

In modern construction, concrete durability and surface performance have become critical evaluation standards. Traditional concrete surfaces often suffer from dusting, abrasion, cracking, and chemical attack over time. To address these issues, Lithium Silicate has emerged as a high-performance solution for concrete densification and surface hardening.

Industrial buildings, warehouses, logistics centers, and parking structures rely on durable concrete floors to withstand heavy traffic, mechanical loads, and long-term use. Yet, many projects face recurring problems:

In industrial and commercial construction, concrete floors are widely used—but they also face common and costly problems: dusting, low surface strength, abrasion, and high maintenance requirements. Lithium silicate–based solutions are specifically designed to address these issues at their root.

As a Chinese chemical materials manufacturer, we specialize in providing high-quality Lithium Silicate products. In the construction industry, particularly for flooring applications, we understand the critical importance of improving concrete durability and surface performance. This article details the key role of lithium silicate as a concrete hardener and sealer, as well as the value we provide as a professional manufacturer.
