Bottom Line
Verdict
Grind and Seal Australia offers affordable grind-and-seal finishes at $40–$85/sqm (average $63/sqm) — the most cost-effective polished concrete option with fast 1–3 day turnaround for typical residential projects. Policrete's mechanically polished concrete at $85–$160/sqm (average $123/sqm) delivers a superior high-gloss finish with better durability and stain resistance, but costs approximately 95% more per sqm. Grind-and-seal finishes rely on a topical sealer that needs recoating every 2–5 years ($15–$35/sqm), while mechanically polished floors use a densifier and penetrating guard that lasts 5–10 years with minimal maintenance. For high-traffic residential areas and commercial spaces, mechanical polishing provides better long-term value despite the higher upfront cost. For garages, laundries, and budget-conscious projects, grind and seal delivers excellent results at a significantly lower price point.
Choose Grind and Seal Australia if budget is your primary concern, you want a fast turnaround, or the floor will be in a low-to-moderate traffic area like a garage, laundry, or spare bedroom. Choose Policrete's mechanical polish if you want the highest durability, lowest long-term maintenance cost, and a premium mirror-finish appearance for living areas, kitchens, or commercial spaces where the floor will be a design feature.
Comparison FAQ
Grind and Seal Australia is cheaper on average in this comparison, but the right answer depends on your specific requirements including floor area, desired finish level, slab condition, and whether decorative treatments are needed.
The finish level (grind and seal vs honed vs mechanical polish), slab preparation requirements, sealer type and longevity, diamond grit sequence, densifier brand, warranty terms, and the scope of included work (preparation, crack repair, edge work, clean-up) usually affect the total cost and value more than a blended average. Always confirm exactly what is included in the quote.
