What does concrete grinding and polishing involve?
The source describes multi-step work using diamond abrasives, beginning with coarse pads and progressing through finer grits before the selected polished or coated finish.


Auckland cleaning, floors & restoration
A multi-step procedure for concrete polishing using diamond abrasives through approximately 10 stages, progressing from coarse to fine grits.
Quick answers
A: Floor size, concrete hardness, and desired gloss level determine timing. Our team can polish 500 sq ft of standard concrete to a medium gloss in 1 to 2 days. High gloss polishing takes longer than lower sheen finishes.
A: Multi-step grinding and polishing with specialised diamond abrasives to smooth and finish the concrete surface. Starting with coarse grit pads, closing pores and removing imperfections, then refining with progressively finer grits down to a super fine polish.
A: Extreme densification makes resealing unnecessary for 5+ years. Optional protective coatings may need touch ups every 2 to 4 years in high traffic areas.

The source describes multi-step work using diamond abrasives, beginning with coarse pads and progressing through finer grits before the selected polished or coated finish.
The source lists matte, satin, semi-gloss and high-gloss outcomes. Concrete hardness, existing condition, aggregate exposure and the desired gloss affect the process.
Crack repair, hole filling and treatment of imperfections are listed as an initial stage, but repairs and slab variation may remain visible in the finished surface.
Existing concrete can be assessed for grinding, polishing or coating. Old coatings, stains, scratches, cracks and contamination must be reviewed because they affect preparation and the likely result.
Before requesting a quote
Describe existing coatings, cracks, holes, repairs, stains or contamination; confirm occupied areas, edge access and the required gloss or coating system; clear the work area where agreed and identify any site constraints before inspection.
Realistic expectations
Cracks, previous repairs, slab variation, contamination and variable aggregate exposure can remain visible or affect the chosen system. Grinding, polishing, grind-and-seal and coating preparation are different scopes and should not be treated as interchangeable.
Service-specific process

Process and proof
Approved service imagery illustrates the material or process; the final scope remains based on the actual site.
Preparation and access
Describe coatings, repairs, cracks, contamination, occupied areas, edge access and the finish required.
Aftercare
Use and maintenance depend on the agreed finish system; confirm handover requirements for the actual slab.

A multi-step procedure for concrete polishing using diamond abrasives through approximately 10 stages, progressing from coarse to fine grits.
Stage 1: Crack Repair Cracks, holes, or imperfections in the concrete with filler and epoxy resins.
Stage 2: Initial Grinding Uses 16 to 30 grit coarse pads.
Stage 3: Successive Grinding 60 to 3000 grit progressively finer pads.
Stage 4: Burnishing Very fine resin pads to burnish the floor to a high gloss level.
Epoxy Coatings: Extremely durable, chemically resistant surface barriers.
Polyurethane Sealers: Highly scratch, scuff, and UV resistant.

Concrete grinding, polishing and coating are related but different scopes. Grinding can remove surface irregularities or prepare concrete; polishing refines the surface through progressively finer stages; coatings add a separate film-forming system. The existing slab, cracks, contamination, moisture, hardness, required finish and future use determine which approach is suitable.
For Auckland and wider New Zealand projects, discuss dust control, edge work, access, power, noise, curing, slip expectations and re-entry before work starts. Old coatings or deep contamination may need testing or additional preparation. Related floor services include block honing and sealing, tile and grout cleaning, vinyl floor care and floor sanding, but the correct method depends on the substrate rather than appearance alone.
