Reduced dusting
Helps limit powdering on mature or soft surface layers—especially under forklift traffic.
Product Construction Chemicals
Concrete Densifier (Sodium Silicate)
Penetrating densifier for concrete floors—supports reduced dusting, improved surface hardness, and easier maintenance for industrial slabs and polished concrete systems.
Packaging: drums / IBC / bulk (as applicable)
Documentation: SDS / COA / TDS on request
Project + repeat lanes for contractors and facility operators
Densifier performance depends on surface profile, porosity, finishing method, and curing history. Share slab age, finish (troweled / broom / polished), and site conditions to align the right concentration and application plan.
What it does
Sodium silicate densifiers penetrate into the near-surface pores of concrete and react with available calcium compounds, forming additional binding phases that tighten the surface matrix. The practical result is a floor that tends to shed less dust, feels harder under traffic, and is easier to keep clean in warehouses, factories, and logistics areas.
Surface hardness
Supports improved abrasion resistance by densifying the top layer when applied correctly.
Maintenance efficiency
A tighter surface typically cleans faster and supports consistent appearance in high-use spaces.
This product is intended as a densifier/hardener treatment. It is not a standalone chemical-resistant coating. For aggressive chemical exposure, consider dedicated coating systems (epoxy/PU) depending on requirements.
Applications
Typical use cases. Tell us the slab profile, traffic type, and finish target to align the correct specification.
- Warehouses and logistics floors (forklift and pallet traffic)
- Manufacturing and assembly areas (dust control + cleaning efficiency)
- Parking decks and ramps (selected cases; confirm suitability)
- Pre-polish densification in polished concrete workflows
- Maintenance densification on older slabs showing surface powdering
New slabs
Applied after appropriate curing/finishing stage to support long-term dusting control.
Existing floors
Used after cleaning and profile preparation; results depend on porosity and contamination level.
Polished concrete
Often used between grinding steps; helps tighten the surface before final polishing/guard systems.
Application workflow
Field-friendly guidance. Final procedure should follow the TDS and site QA requirements.
1) Surface prep
Remove dust, curing compounds, sealers, oils, and residues that block penetration. Mechanical scrubbing/grinding may be required on dense or contaminated floors.
2) Apply to saturation
Apply evenly (low-pressure spray + microfiber) and keep the surface wet long enough for penetration. Avoid puddles; distribute uniformly.
3) Work-in & clean-up
Work the material into the surface. Remove excess residue before it dries (as instructed) to reduce streaking/white deposits.
4) Cure time
Allow reaction time before opening to heavy traffic or proceeding with polishing steps. Timing depends on temperature, porosity, and workflow.
5) Optional second coat
Highly porous slabs or high-wear zones may require additional applications—confirm uptake and performance targets.
6) Verify results
Confirm dust reduction/hardness improvement after the reaction period. For critical floors, validate with site QA methods aligned to project requirements.
Coverage & performance drivers
Coverage varies widely with porosity, finish, and slab age. Very dense, steel-troweled floors may absorb less, while porous or sandier surfaces may require more. For accurate estimating, share a photo and an approximate water-drop absorption check result (fast/slow absorption).
- Porosity and surface profile drive penetration and consumption
- Residues/sealers can block reaction—prep is decisive
- Excess residue left to dry can cause visible deposits—manage clean-up per TDS
Safety note: sodium silicate solutions are alkaline. Use appropriate PPE and follow SDS handling guidance.

FAQ
Common questions from contractors, facility managers, and procurement teams.
Is it a coating?
No—densifiers penetrate and react in the near-surface. They do not create a thick film like epoxy/PU coatings and do not replace chemical-resistant floor systems.
Will it change the appearance?
It can slightly affect reflectivity and may leave visible residue if excess material dries on the surface. Proper application and clean-up reduce risk.
Can it be used before polishing?
Yes, sodium silicate densifiers are often used in polished concrete workflows. The exact step timing depends on tooling sequence and slab response.
How long until traffic?
Timing depends on temperature, porosity, and procedure. Follow the TDS; for heavy traffic areas, allow sufficient reaction and drying time.
What about old floors with oil contamination?
Penetration can be blocked by oils/grease and prior sealers. Cleaning and mechanical preparation may be required to achieve meaningful densification.
What documents do you provide?
SDS/COA are typically available on request. TDS and supporting documentation can be supplied depending on grade and lane.
