Polished Concrete in New Jersey: The Low-Maintenance Showroom Finish

How polished concrete is actually made

The process is mechanical, not chemical. We start with coarse metal-bond diamonds to flatten the slab and expose aggregate, then move through progressively finer resin-bond diamonds (100, 200, 400, 800, 1500, 3000 grit). A lithium silicate densifier is applied mid-process to harden the surface, and a final burnish brings the floor to a glass-like sheen.

• Diamond grinding through 6–8 grit steps
• Lithium or sodium silicate chemical densifier
• Optional dye for color (acetone or water-based)
• Final stain guard to repel oil and water
• Gloss levels: matte, satin, semi-polished, high-polish

Where polished concrete makes the most sense

Anywhere foot traffic is high, lifecycle cost matters, and a clean industrial-modern aesthetic fits the brand. We install polished concrete across NJ in auto dealerships, breweries, retail stores, restaurants, gyms, warehouses, and modern residential lofts.

• Auto dealerships & showrooms
• Retail flagships and boutiques
• Restaurants, cafés, and breweries
• Warehouses and distribution centers
• Loft-style residential conversions

What it costs in NJ

Polished concrete in New Jersey typically runs $5–$12 per square foot depending on gloss level, dye, slab condition, and aggregate exposure. Cream polish (no aggregate exposure) sits at the low end; salt-and-pepper and full-aggregate exposure runs higher because more grinding passes are required.

Maintenance is almost nothing

Sweep daily, damp-mop with a neutral pH cleaner weekly, and burnish once every 12–24 months to restore the sheen. No stripping, no waxing, no recoating. A polished concrete floor installed today will outlive every other finish in the building.
