Unsealed concrete sheds fine particles under foot and forklift traffic, settling on products, equipment, and workers. Portland Concrete applies silicate densifier systems that chemically harden the surface and eliminate dust generation. No full coating needed. Free written estimate included.
Concrete surfaces naturally shed dust as traffic wears the top layer. In manufacturing and warehouse settings, this becomes a real operational cost: product contamination, air quality issues, equipment fouling, and constant sweeping. The root cause is the porous surface itself.
A silicate densifier (sodium or lithium) soaks into the slab and chemically reacts with the concrete's calcium hydroxide, forming additional binder that closes surface pores and hardens the wear layer. The result is dramatically reduced dust generation at a fraction of the cost of a full epoxy or polyurethane coating system. Optional topical sealer can be added for extra gloss and protection.
The floor is inspected for existing coatings, heavy wear, or contamination. Light grinding removes loose material and opens the surface so the densifier can penetrate effectively.
Apply silicate densifier
Sodium or lithium silicate is applied at the manufacturer's specified rate, kept wet on the surface for the required reaction time, then excess is removed and the slab is allowed to dry.
Optional topcoat sealer
If specified, a topical sealer is applied after densifier cure for additional surface protection, easier cleaning, and optional gloss. Many facilities skip this step and rely on densifier alone.
Test and document
Surface hardness is verified and dust generation is tested informally. Maintenance guidelines and re-application intervals are documented for the facility team.
High ROI, low cost
Densifier Is the Smart Dust-Control Choice
Densifier-only treatment delivers one of the best cost-to-benefit ratios in industrial flooring. Application is quick, cost is low relative to full coating systems, and the dust reduction is immediate and measurable. We recommend it as the first step in any warehouse or light-manufacturing facility where dust is the primary concern.
Pair with adjacent warehouse epoxy if specific high-traffic zones need full coating while general areas just need dust suppression. Coordinate with other manufacturing services for a complete floor strategy.
Silicate types, topcoat decisions, durability, and phased application during operations.
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.
Client reviews
What Portland Facilities Say About Dust-Control Sealing
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, Portland
★★★★★
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, Vancouver
★★★★★
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, Hillsboro
★★★★★
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.
