Bare concrete dusts under traffic, contaminating products, clogging filters, and creating cleanup overhead that adds up fast. Gatineau Concrete applies densifier and sealer systems that chemically lock down the surface, eliminating dust generation without the cost of a full epoxy coating. Every project starts with a free written estimate.
Bare concrete generates dust as the surface wears under traffic, particularly forklift wheels and foot traffic on heavily-trafficked sections. The dust gets on products, into machinery, into the air, and into the lungs of operators. Cleaning is constant; the cause is the floor itself.
A densifier (sodium or lithium silicate) penetrates the surface and reacts with the concrete's calcium hydroxide to form additional calcium silicate hydrate binder, dramatically reducing surface porosity and dust generation. Optionally followed by a topical sealer for additional protection. The combination is a fraction of the cost of a full epoxy coating and addresses the dust problem directly.
The floor is cleaned and any loose dust or contaminants removed, with light grinding where the surface has heavy wear or existing coatings that need to come off before the densifier can penetrate.
Apply silicate densifier
The chosen silicate densifier (sodium or lithium) is applied at the manufacturer's coverage rate, kept wet on the surface for the reaction time required, then any excess is removed before drying.
Cure and optionally seal
The densifier is allowed to cure into the slab, after which an optional topical sealer can be applied for additional surface protection or sheen, depending on the use case and budget.
Verify and document
Surface hardness and dust generation are verified informally (sweep test), and the maintenance protocol (re-application interval, compatible cleaning chemicals) is documented for facility maintenance.

Densifier Is the Quietly-Powerful Tool
Densifier-only treatment is one of the highest-ROI industrial floor moves available. The application is fast, the cost is low compared to coating systems, and the dust reduction is dramatic in any traffic-heavy area. We recommend it as a first-pass treatment in warehouses, light manufacturing, and any zone where dust is the primary concern.
Coordinate with adjacent warehouse coating if specific zones need full coating while general areas just need dust control, and with the rest of manufacturing floor work.
Sodium vs lithium silicate, optional topcoats and when sealing alone is enough.
Lithium silicate generally provides better densification and less efflorescence; sodium silicate is lower-cost. We recommend based on your facility's needs and budget; lithium is our default for premium applications, sodium for value-focused installs.
Not always. Densifier-only is sufficient for dust control in many warehouse and light-manufacturing settings. A topical sealer adds gloss, additional surface protection, and easier cleaning; the right answer depends on your facility's needs.
Dust-proofing addresses dust generation at a fraction of the cost of full coating, but does not provide chemical resistance, impact protection, or significant aesthetic improvement. Full coating addresses all those plus dust; dust-proofing focuses on the dust problem only.
A properly applied densifier provides decades of dust control; reapplication is rarely needed unless the slab sees significant wear. Topical sealers may need refresh every several years depending on traffic and cleaning.
Yes, with zone-by-zone phasing. Each treated zone is offline for a single shift or less during application and cure; operations continue in untreated zones. The phasing plan is part of the quote.

What Gatineau Operations Say About Their Dust-Proof Floors
Lithium silicate densifier across our entire warehouse floor. Dust generation dropped dramatically, cleanup time per shift cut by hours. Best maintenance dollar we have spent in years.
Z. Y4
Warehouse Manager, Gatineau
★★★★★
They recommended dust-proofing instead of upselling us to full coating. The honest spec saved real budget and solved the actual problem we had. Trust earned.
Y. Y4
Plant Manager, Ottawa
★★★★★
Phased application across the plant over two weekends. Operations never stopped, dust generation in treated zones was noticeably lower by the next shift. Quick, effective, clean.
Q. Y4
Operations Director, Barrhaven
★★★★★
Added a topical sealer on top of the densifier for the easier-clean factor. The combined result is dust-free, easy to maintain, and cost a fraction of what coating would have.
