01
Different from traditional sodium and potassium silicate floor hardeners that are prone to surface blooming and whitening, the lithium-based formula adopted by Sanlee Chemical features ultra-high chemical stability.
02
The product realizes structural reinforcement rather than superficial protection. After penetrating into the concrete interior, it triggers a permanent hydration reaction to generate solid C-S-H gel, which tightly fills micro-pores and repairs loose concrete structures.
03
As a zero-VOC, odorless and non-toxic water-based chemical material, our lithium silicate floor densifier fully complies with global environmental protection and industrial safety standards.It contains no harmful chemical ingredients.
04
The densified and hardened concrete floor forms an integrated rigid structure with excellent compression resistance, impact resistance and stain resistance. It can withstand long-term heavy-duty rolling and high-frequency friction.
Our liquid lithium silicate concrete densifier adopts standard industrial packaging, including 20 liter plastic drums, 200 liter plastic drums and 1000kg IBC tote tanks, and supports customized packaging according to customer needs. All packaging containers are sealed and leak-proof, which can effectively avoid product leakage and pollution during transportation. As a professional sodium silicate supplier, we support flexible packaging and bulk shipping for global customers.
Store the industrial lithium silicate in a cool, dry and ventilated warehouse, keep away from high temperature, direct sunlight and freezing environment. The ambient storage temperature is controlled at 5℃-35℃. Sealed storage is required after opening to prevent water evaporation and surface crystallization. Under standard storage conditions, the product shelf life is 12 months. It is forbidden to mix with acid substances to avoid chemical reaction and product deterioration.
It is a penetrating concrete hardening agent designed to densify, harden and dust-proof cement-based concrete floors. It reacts with internal concrete ingredients to form solid C-S-H gel, permanently solving floor dusting, sanding and low hardness problems, and improving overall floor durability for industrial, commercial and clean space scenarios.
Compared with traditional sodium silicate densifiers, lithium silicate formula features more stable molecular structure, lower alkali content and zero efflorescence. It penetrates deeper into concrete without causing surface whitening or blooming, delivering more uniform curing effects and longer-lasting floor performance with fewer construction defects.
Yes. The product is zero-VOC, odorless, non-toxic and water-based, containing no harmful volatile substances. It complies with global environmental regulations and food-grade safety standards, with no secondary pollution during construction and service life, safe for food factories, pharmaceutical workshops and indoor commercial spaces.
No. Different from film-forming floor coatings, this product relies on internal chemical reaction to form an integrated hard structure with concrete instead of forming a surface coating. It will never peel, blister or fade, providing permanent hardening and dustproof effects for the floor.
Yes. Sanlee Chemical is a professional lithium silicate densifier factory focusing on the R&D, production and sales of concrete chemical materials. We strictly control raw material purity and production processes, providing high-quality, stable and cost-effective floor densifier products and professional technical support for global customers.

High-performance potassium silicate concrete densifier hardens & dustproofs concrete from within via chemical reaction. No surface peeling or efflorescence, creates durable stain-resistant polished floors for industrial, commercial and decorative concrete applications, eco-friendly zero VOC water-based formula.

Sodium Silicate Concrete Densifier is a cost-effective liquid concrete hardener & penetrating sealer for all cement surfaces. It reacts with free calcium hydroxide to form compact calcium silicate hydrate gel, densifying porous concrete, stopping dust emission and improving wear & chemical resistance. Odourless, non-flammable and compatible with new or old concrete floors, widely used in…
