Penetration + reaction
Silicate penetrates into pores and reacts with available calcium to form additional C-S-H, tightening near-surface structure.
Product Construction Chemicals
Concrete Densifier (Lithium Silicate)
Lithium silicate densifier for concrete—used for polished concrete workflows and surface hardening. A penetrating, non-film-forming treatment that helps reduce dusting and improves abrasion resistance (substrate dependent).
Non-film forming
Polished concrete
Dust reduction
Abrasion resistance
Spray & spread
Packaging: drums / IBC / bulk (as applicable)
Documentation: SDS / COA / TDS on request
Lead time depends on grade (solids/ratio), lane & volume
Commercial note: Densifier consumption is typically quoted by coverage (m²) and surface profile. Share slab age, finish, polishing grit plan, and expected coverage so we can specify the right grade and propose a realistic supply quantity.
What it does
Lithium silicate densifiers are used to increase surface density and reduce dusting by reacting within the concrete’s pore structure. In typical concrete, free lime (calcium hydroxide) can react with silicates to form additional calcium silicate hydrate (C-S-H), which can improve surface hardness and wear performance over time (actual results depend on concrete quality, finishing, and application).
Dust reduction
Helps bind fines and reduce powdering—useful in warehouses, logistics centers, and industrial floors.
Polished concrete support
Commonly used between grinding steps to increase density and improve clarity/gloss potential.
Non-film-forming
Penetrating chemistry—does not create a topical film when applied and cleaned correctly.
Typical substrates
Power-troweled slabs, burnished floors, polished concrete, tilt-up panels, and some precast elements (confirm by trial on site).
Limitations
Performance depends on porosity and available reactants. Always test a small area first—especially on colored floors, soft/weak concrete, or surfaces with curing compounds, sealers, or contamination.
Note: This page provides typical guidance for procurement and specification. Always follow the grade-specific SDS/TDS for the supplied product.
Applications
Typical usage patterns. Tell us your process and constraints and we’ll align the right specification.
- Polished concrete floors (commercial & industrial)
- Warehouse and logistics floors—dustproofing and wear improvement
- Manufacturing facilities and workshops—reduced powdering and easier maintenance
- Retail slabs and public areas—clarity/gloss support (system dependent)
- Tilt-up and some precast elements—surface tightening (confirm by trial)
Where densifiers fit in a polishing system (typical)
Densifier is often applied after initial grinding and before higher grits. Exact step depends on slab hardness, desired finish, and the polishing contractor’s method.
How lithium silicate densifiers work
Technical context to help you specify the right grade and set realistic expectations.
Reduced efflorescence risk
Lithium-based densifiers are often selected for polished concrete where appearance matters (system dependent).
Outcome depends on slab
Concrete mix design, curing, troweling, and porosity drive results—trial areas are recommended for specification.
Common issues that reduce performance
- Curing compounds/sealers blocking penetration
- Oil/grease contamination
- Excess densifier drying on surface (residue)
- Very weak/soft concrete or high laitance
Controls & acceptance
Many projects define acceptance by reduced dusting, improved cleanability, gloss/DOI in polished systems, and/or abrasion performance. Share your KPI so we can align grade, coverage estimate, and documentation.

Supply, documentation & procurement lane
Procurement-ready supply with defined documentation, packaging, and lane options.
Packaging options
Drums and IBC are common. Bulk supply can be arranged depending on lane, region, and volume.
Private label / contract fill
Private label and contract filling may be available depending on MOQ and destination requirements.
Lead time & Incoterms
Quoted per destination and lane (EXW/FOB/CFR/CIF/DDP where feasible). Lead time depends on grade and volume.
To speed up quoting
Send: required grade (or let us propose), total m², desired packaging, delivery location/port, and documentation pack (SDS/COA/TDS). We’ll reply with a matched grade, typical application notes, and a commercial offer.
Request quotation
Share your concrete floor details and we’ll propose a suitable lithium silicate densifier grade aligned to your application method and finish target.
Technical inputs
Concrete age, finish, porosity notes, polishing plan, desired outcome/KPI.
Quantity planning
Area (m²), estimated coverage range, number of coats (if planned), schedule constraints.
Commercial inputs
Volume needed, packaging, destination/Incoterms, SDS/COA/TDS and COA parameters.
Tip: If you have a polishing contractor method statement or a previous densifier brand/spec, include it—this helps match the correct solids/ratio grade.
