01
This high-performance inorganic silicate treatment features excellent permeability, capable of penetrating 3–5mm deep into concrete interior to trigger sustainable chemical reactions with free calcium hydroxide.
02
Optimized with premium potassium silicate formula, the product effectively avoids the common whitening, blooming and efflorescence defects of traditional sodium silicate densifiers.
03
Formulated with pure inorganic water-based raw materials, the product is zero-VOC, odorless, non-toxic and non-flammable, fully compliant with global environmental protection and construction safety standards.
04
Featuring a simple one-time construction process, the product requires no complex auxiliary equipment or repeated coating, greatly shortening the construction cycle and reducing labor and time costs.
Our liquid potassium 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 potassium silicate concrete densifier 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.
Compared with traditional sodium silicate products, our potassium silicate formula effectively eliminates efflorescence, whitening and blooming issues. It delivers more stable chemical reactivity, better penetration uniformity, and longer-lasting protection without peeling or discoloration after long-term use.
The high-permeability formula can penetrate 3–5mm into concrete substrates, triggering continuous chemical reactions inside the concrete to generate stable C-S-H crystals. It achieves integral floor hardening instead of superficial surface coating protection.
Absolutely. It is a water-based inorganic solution with zero VOC, odorless, non-toxic and non-flammable features. It meets global environmental and construction safety standards, safe for indoor workshops, basements, supermarkets, food factories and pharmaceutical clean rooms.
No. The transparent formula will not alter the concrete’s original color, texture or aesthetics. After curing, it forms a natural subtle gloss, enhancing the polished effect without causing yellowing, whitening or surface residue.
It features a fast curing cycle with simple one-time construction. The surface dries quickly after application, and the chemical hardening reaction continues gradually. The floor can bear light walking within 24 hours and reach full hardness and wear resistance within 7 days under normal temperature conditions.

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…

Premium lithium silicate floor densifier for polished & raw concrete. Water-based zero-VOC solution penetrates deep to densify, harden and dustproof floors permanently via chemical C-S-H reaction. Less efflorescence than sodium silicate, abrasion-resistant, breathable and easy to polish. Perfect for industrial, commercial and warehouse concrete flooring.

Our liquid lithium silicate densifier features ultra-stable silica-lithium oxide ratio, high purity and minimal impurities. It penetrates concrete pores deeply for permanent hardening, delivers consistent low alkalinity and excellent compatibility with concrete sealers, polishing agents and mineral admixtures. Perfect for industrial floor densification, warehouse concrete polishing, commercial building ground treatment, garage floor reinforcement and high-durability…
