What Affects the Price of Polished Concrete?
Level of polish and finish type
The level of polish is the biggest cost driver. A basic grind and seal ($50–$100/sqm) is the most affordable option. Honed concrete ($60–$120/sqm) provides a mid-range matte finish. A full mechanical polish ($80–$150/sqm) with multiple diamond grinding passes delivers the highest gloss and durability. Decorative options like staining ($100–$180/sqm) and exposed aggregate ($70–$130/sqm) add complexity and cost. The number of grinding passes directly affects both the final appearance and the price.
Condition of the existing slab
New slabs poured specifically for polishing are the most cost-effective to finish. Existing slabs that need coating removal ($10–$20/sqm extra), crack repair ($15–$40 per linear metre), levelling ($30–$70/sqm), or adhesive removal add significantly to the preparation time and cost. Slabs with severe damage or contamination may require an overlay ($90–$160/sqm) rather than direct polishing. Always have the slab assessed before getting a polishing quote.
Floor area and access
Larger floor areas benefit from economies of scale — a 200sqm project typically costs 15–25% less per sqm than a 50sqm project due to equipment mobilisation and setup costs being spread over a larger area. Access for heavy grinding equipment (planetary grinders weigh 200–400kg) must be considered — ground floor is standard, but upper floors or areas with restricted access may incur additional costs for smaller equipment and longer timeframes.
Decorative elements and colour
Plain polished concrete with no colour treatment is the most affordable option. Adding acid stains ($20–$40/sqm extra), water-based dyes ($15–$30/sqm extra), or scoring patterns ($10–$25/sqm extra) increases the decorative value but adds cost and complexity. Exposed aggregate finishes require deeper grinding which consumes more diamond tooling. Custom logos, borders, and inlaid designs are premium additions that can add $30–$80/sqm to the base polishing cost.
Polished Concrete Finishes Compared
Compare grind and seal, honed, mechanically polished, and stained concrete options
| Finish Type | Price Range | Pros | Cons | Best For |
|---|---|---|---|---|
| Grind & Seal | $50–$100/sqm | Most affordable option, fast installation, wide range of sealer finishes from matte to high gloss, easy to maintain and recoat | Topical sealer can wear and scratch over time, requires resealing every 2–5 years, not as durable as mechanical polish in high-traffic areas | Budget-conscious residential projects, garages, laundries, and areas where cost is the primary concern over long-term durability |
| Honed Concrete | $60–$120/sqm | Natural matte finish with subtle aggregate exposure, more durable than grind and seal, good balance of cost and aesthetics | Does not achieve a high-gloss mirror finish, may show stains more readily than sealed surfaces if not treated with densifier | Contemporary residential interiors wanting a natural concrete look without high gloss, commercial spaces preferring understated elegance |
| Mechanically Polished | $80–$150/sqm | Highest durability and stain resistance, mirror-like gloss finish, no topical sealer to wear off, lowest long-term maintenance cost | Highest upfront cost, requires multiple grinding passes (4–7 stages), longer installation time, shows imperfections in the slab more visibly | Premium residential floors, high-traffic commercial spaces, retail showrooms, and anywhere long-term durability justifies the higher upfront investment |
| Stained Polished | $100–$180/sqm | Unique colours and patterns, each floor is one-of-a-kind, can mimic natural stone or create bold modern designs, combines aesthetics with durability | Most expensive option, colour results can be unpredictable with acid stains, requires skilled application, colour cannot be easily changed once applied | Feature floors in living areas, commercial spaces wanting a distinctive branded look, restaurants, galleries, and high-end retail |

How Polished Concrete Is Installed
Step-by-step guide from assessment to completed floor
Assessment and quotation
A polished concrete specialist inspects the existing slab to assess its condition, hardness, moisture content, and suitability for polishing. They will identify any cracks, coatings, or contaminants that need addressing, discuss finish options and colours, and provide a detailed written quote. Most reputable contractors offer free site assessments. Allow 1–2 weeks for the assessment and quote process. Get at least three quotes for comparison.
Surface preparation
Before polishing can begin, the slab must be properly prepared. This includes removing any existing coatings, tiles, carpet glue, or paint using coarse diamond grinding or chemical strippers. Cracks are repaired with colour-matched epoxy or polyurea filler. Uneven areas are ground level. A moisture test is performed — if moisture levels exceed acceptable limits, a moisture mitigation system may be required before proceeding.
Grinding and cutting
The main grinding phase uses progressively finer diamond segments — starting with coarse grits (30–60) to remove material and flatten the surface, then moving to medium grits (100–200) to refine the profile. For exposed aggregate finishes, deeper cuts are made to reveal the stones within the concrete. This stage generates significant dust — professional contractors use industrial vacuum systems with HEPA filters to control airborne particles.
Polishing
After the grinding phase, a chemical densifier (lithium silicate hardener) is applied to harden the concrete surface and close the pores. The floor is then polished using fine diamond pads (400–3000 grit depending on the desired gloss level). Each pass increases the sheen and refines the surface. A full mechanical polish typically involves 4–7 progressive passes. This is where the floor transforms from a dull ground surface to a smooth reflective finish.
Sealing and protection
The final step depends on the finish type. Grind-and-seal floors receive a topical sealer (polyurethane, acrylic, or epoxy) that sits on top of the surface. Mechanically polished floors receive a penetrating guard or impregnating sealer that protects without changing the appearance. Stained floors are sealed to lock in the colour. The sealer protects against stains, moisture penetration, and daily wear. Most sealers require 24–48 hours to fully cure before the floor can receive foot traffic.
Curing and handover
After sealing, the floor needs time to fully cure. Light foot traffic is typically permitted after 24 hours, but heavy furniture and equipment should be kept off the floor for 3–7 days depending on the sealer type. Your contractor will provide care instructions including recommended cleaning products, maintenance schedules, and when resealing should be considered (typically every 2–5 years for topical sealers, or as needed for penetrating guards).
How to Save Money on Polished Concrete
Choose grind and seal over mechanical polish
A grind-and-seal finish ($50–$100/sqm) delivers an attractive polished look at 40–60% less than a full mechanical polish ($80–$150/sqm). For low-traffic residential areas like bedrooms and home offices, grind and seal provides excellent value with a wide range of gloss levels available through different sealer types.
Polish during new construction
Polishing a newly poured slab during construction saves 15–25% compared to retrofitting polished concrete into an existing home. New slabs can be specified with the right mix design, aggregate, and finish for polishing, and there is no need for coating removal or extensive surface preparation. Coordinate with your builder to include polishing in the construction schedule.
Maximise your floor area
Larger projects benefit from significant economies of scale. A 200sqm project typically costs 15–25% less per sqm than a 50sqm project because equipment mobilisation, setup, and edge work costs are spread over a larger area. If you are planning to polish multiple rooms, do them all at once rather than in stages.
Skip decorative extras unless essential
Plain polished concrete with no staining or scoring is the most affordable option. Acid stains ($20–$40/sqm extra), decorative scoring ($10–$25/sqm extra), and custom inlays ($30–$80/sqm extra) add visual impact but increase costs significantly. Consider whether the natural beauty of the polished concrete and its inherent aggregate patterns are sufficient before adding decorative treatments.
Polished concrete costs in Australia range from $15–$35 per sqm for sealer application only, $50–$100 per sqm for a grind-and-seal finish, $60–$120 per sqm for honed concrete, and $80–$150 per sqm for a full mechanical polish. Decorative options like staining cost $100–$180 per sqm. Commercial projects over 200sqm typically attract lower per-sqm rates. Prices include GST and vary by city, finish type, and slab condition.
Polished concrete is generally comparable to mid-range tiles ($60–$120/sqm installed) and significantly cheaper than quality hardwood timber flooring ($120–$250/sqm installed). A grind-and-seal finish ($50–$100/sqm) is one of the most affordable flooring options for homes built on concrete slabs. The long-term maintenance cost of polished concrete is also lower — no grout to clean, no boards to sand and refinish, and no need for replacement.
Mechanically polished concrete is one of the most durable flooring options available — it can last 20+ years with minimal maintenance in residential settings and 10–15 years in high-traffic commercial environments before requiring significant re-polishing. Grind-and-seal finishes typically need resealing every 2–5 years ($15–$35/sqm) to maintain their appearance and protection. The concrete slab itself is essentially permanent.
Most concrete slabs can be polished, but the result depends on the slab's condition, hardness, and mix design. New slabs poured with polishing in mind deliver the best results. Existing slabs with coatings, adhesives, or significant damage require additional preparation ($30–$70/sqm). Very old or soft concrete may not polish well and may be better suited to a decorative overlay ($90–$160/sqm). Always have the slab assessed by a specialist before committing.
Polished concrete can be slippery when wet, similar to polished stone or glazed tiles. For wet areas and outdoor applications, slip-resistant additives can be mixed into the sealer or a lower polish level can be specified to maintain adequate traction. Australian Standard AS 4586 provides slip resistance classifications — discuss the appropriate rating with your contractor, particularly for bathrooms, pool surrounds, and commercial kitchens.
