Polished Concrete Costs in Victoria

Polished concrete is the mechanical grinding and polishing of a concrete slab to produce a smooth, refined surface ranging from a soft satin matte through to a glass-like mirror gloss. Pricing in 2026 spans roughly $50 per square metre at the bottom for a basic warehouse grind and seal through to about $220 per square metre at the upper end for a fully exposed aggregate seven step polish with dye or colour. Most modern residential and retail projects across Melbourne fall between $120 and $180 per square metre once typical inclusions for densifier, joint treatment, edge work, and a guard or impregnating sealer are factored in. Pricing assumes the slab is sound and accessible, with major rectification, removal of existing floor coverings, and complex edge work where cabinetry or fixtures restrict machine access lifting these numbers.

The variable that catches most homeowners and project managers off guard on polished concrete is how much the slab itself drives the finished outcome and the achievable price. A purpose poured polished concrete slab specified for the intended exposure level, finished flat to the appropriate floor flatness tolerance, jointed with the polish in mind, and cured under controlled conditions can be polished economically because the grinding sequence does not need to do remedial work. An existing slab being polished retrospectively, particularly an older slab with paint, glue residue, level variations, or extensive crack damage, can require so much preparatory grinding that the project takes 50 percent longer and costs proportionally more than the equivalent new pour. The hub page on general concreting services in Victoria covers the broader concreting category, and the related guide to concrete grinding in Victoria covers the mechanical preparation work that underpins polished finishes.

What a Polished Concrete Project Includes

A complete polished concrete project on an existing slab in Victoria takes between three and eight working days on site for a typical residential floor of 80 to 150 square metres, depending on the polish level, the slab condition, and the access. The first day usually covers slab assessment, including moisture testing, hardness testing, and identification of any cracks, joints, or surface defects requiring repair. Day two involves any preliminary repair work including crack chasing and filling with semi-rigid epoxy or polyurea, joint preparation, and removal of any old coatings or adhesives.

The grinding sequence proceeds across days three through six depending on the specified polish level. Heavy initial grinding using metal-bond diamond segments removes the cement paste surface, exposes the aggregate to the design level, and corrects any level variations or trowel marks. Mid-grit transitional polishing using hybrid bond resin diamonds prepares the surface for the final polish, and the densifier is applied at this stage to react with the calcium hydroxide in the slab and produce calcium silicate hydrate, the same compound that gives concrete its strength. The final polish runs through progressively finer resin-bond diamond pads to bring up the gloss to the specified level. The last day typically covers application of a topical guard or impregnating sealer, the final clean, and the project handover.

The materials and equipment supplied for a typical 100 square metre residential polished concrete project include a planetary grinder (usually a 600 or 800 millimetre machine such as those manufactured by HTC, Husqvarna, Lavina, or Diamatic), a small edge grinder for areas the planetary cannot reach, dust extraction running through a HEPA-rated industrial vacuum, lithium silicate densifier in 20 litre drums applied at coverage rates around 5 to 8 square metres per litre depending on slab porosity, the diamond tooling sequence (typically 6 to 12 sets of segments and pads progressing through the grit range), joint and crack filler material, surface guard or sealer at recommended coverage rates, and consumables including water for wet grinding or dust suppression. The crew typically includes a lead polisher who runs the planetary, an edge specialist working hand grinders into corners and edges, and one or two assistants managing the densifier, joints, and sealer.

Beyond the polishing itself, a properly scoped quote should include the protection of adjacent surfaces during grinding (walls, cabinetry, glazing all need protective covering against polishing slurry and dust), removal of dust and slurry through HEPA filtration, the management of any moisture from wet grinding methods, and a final clean handover ready for furniture move-in. New slab pours that will be polished require additional coordination at the pour stage, with the slab needing to be cured under controlled conditions, jointed at appropriate spacings using saw cuts rather than tooled joints, and finished to the floor flatness tolerance suitable for the polish level specified. For new slab work that will be polished, our concrete slab guide covers the slab specification considerations, and for existing slabs requiring repair before polishing can proceed, our concrete repair guide covers the rectification options.

Aggregate Exposure Levels

The aggregate exposure level is the most consequential aesthetic decision in any polished concrete project and is the variable that most directly determines the finished appearance. Three exposure levels are recognised across the industry. Cream finish polish exposes only the cement paste at the slab surface with no aggregate visible, producing a smooth uniform appearance similar in feel to natural stone or terrazzo without the speckling. The cream finish is the most forgiving level because the underlying aggregate placement and slab compaction do not affect the visible result.

Salt and pepper exposure removes the top 1 to 2 millimetres of the slab to expose the fines and the smaller pieces of aggregate, producing the characteristic flecked appearance that gives the level its name. The exposure is the most popular level across Victorian residential and commercial polished concrete because it adds visual interest without the dramatic impact of full aggregate exposure, and works with most slab compositions that have not been designed specifically for aggregate exposure. Salt and pepper polish is the standard specification for retail fitouts, hospitality interiors, and modern open plan residential homes across Melbourne.

Full aggregate exposure removes 3 to 6 millimetres of the slab surface to fully expose the larger aggregate pieces, producing a result that closely resembles polished terrazzo. The exposure level requires the slab to have been specifically designed and poured for this level, with the aggregate selection (typically including decorative aggregates such as recycled glass, marble, granite, or graded local basalt) loaded toward the surface during the pour and the concrete vibrated to bring the aggregate into the surface zone. Full aggregate exposure on a slab not designed for it produces an uneven appearance with patchy aggregate and is generally not recommended unless the underlying slab was specifically formulated for this finish. The decorative aggregate selections used for polished concrete overlap with those used in exposed aggregate concrete, although the surface preparation methods differ significantly between the two finishes.

Slab Assessment and Suitability

Polishing a concrete slab is in many ways an act of revealing what is already there, and the suitability of the slab for the intended polish level is the single most important assessment to make before signing a polishing contract. New slabs purpose-poured for polishing are specified with concrete grades of 32 MPa minimum and ideally 40 MPa, with controlled curing protocols and saw cut joints rather than tooled joints. Existing slabs being polished retrospectively need a more careful assessment that addresses six main factors.

The first factor is the concrete grade and aggregate quality. Slabs with weak surface paste, soft aggregate, or contaminated aggregate produce inconsistent polish results and may not be able to take a high gloss level. The second factor is surface flatness, with most planetary grinders requiring the slab to be reasonably flat to produce even polish coverage. Slabs with significant high spots or low spots need preparatory grinding to flatten before the polish sequence can proceed. The third factor is moisture, with slabs that have moisture rising through them from below being unsuitable for many sealer systems and at risk of efflorescence after polishing. Moisture testing using calcium chloride or relative humidity probes is the appropriate first step on any below-grade or ground-bearing slab being polished.

The fourth factor is contamination from previous floor coverings. Slabs that have had carpet tiles glued to them, vinyl tiles installed with bituminous adhesive, or epoxy coatings applied may need extensive grinding to remove the contamination before the polish sequence can begin, and in some cases the contamination has penetrated the slab paste deeply enough that polishing will reveal residual stains in the finished floor. The fifth factor is crack damage and joint condition. Visible cracks need to be filled with semi-rigid epoxy or polyurea to prevent the cracks from becoming feature lines in the polished surface, and existing joints need to be cleaned out and refilled with the appropriate filler. The sixth factor is the slab thickness and the depth of any reinforcement. Heavy initial grinding for full aggregate exposure can in extreme cases approach the depth of surface mesh reinforcement, and grinding into reinforcement is a serious defect that compromises both the slab and the polish.

Grinding Sequence and Grit Progression

The grinding sequence is the engineering core of any polished concrete project and progresses through diamond grit sizes from very coarse through to very fine, with each step removing the scratches left by the previous step. The standard three step polish sequence runs through 30 grit, 80 grit, and 200 grit metal-bond and resin-bond diamonds and produces a satin to semi-gloss finish suitable for residential floors and basic retail fitouts. The five step polish adds 400 grit and 800 grit passes, producing a semi-gloss to glossy finish appropriate for premium residential and most retail fitouts. The seven step polish adds 1500 grit and 3000 grit final passes, producing the high gloss mirror finish associated with showrooms and statement designer floors.

The diamond tooling itself comes in three bond systems suited to different grinding conditions. Metal-bond diamond segments are used for the heaviest initial grinding where significant slab removal is needed, with the metal matrix wearing rapidly to expose fresh diamond as the segments cut. Hybrid bond diamonds bridge between the metal bond and the final resin polishing pads, providing controlled cutting at the mid-grit transitions. Resin-bond diamond pads do the final polishing through the higher grits, with the resin matrix providing the cushioning needed to bring up gloss without leaving visible scratches.

Wet versus dry grinding is the operational choice that significantly affects the project logistics. Dry grinding through HEPA-filtered dust extraction is the standard for occupied or partially occupied buildings because no water is introduced and the slurry cleanup is much simpler. Wet grinding produces faster cutting and better diamond tool life but generates a slurry that must be contained, vacuumed, and disposed of properly under EPA Victoria waste handling rules where the slurry exceeds threshold quantities. The choice between wet and dry is generally made by the contractor based on the equipment they run and the project context, with dry grinding being the dominant method for residential and retail polishing in Melbourne. Where existing concrete needs to be cut for new openings or service penetrations during the polishing project, our concrete cutting guide covers the diamond saw work involved.

Densification and Chemistry

Densification is the chemical step that transforms a ground slab from a soft porous surface into the dense durable polished surface that distinguishes polished concrete from a simple ground floor. Lithium silicate densifier is the modern standard, applied during the mid-grit transition stage of the polish sequence and reacting with the calcium hydroxide that is naturally present in cured concrete. The reaction produces calcium silicate hydrate, the same compound that gives concrete its compressive strength, and the densifier effectively converts the soft cement paste at the slab surface into a hardened, denser layer that polishes more cleanly and resists wear and staining far better than untreated concrete.

Sodium silicate and potassium silicate densifiers were the dominant systems before lithium silicate was widely adopted and are still used on some lower-cost projects, but they leave residue on the surface that needs to be removed and they produce less consistent results than lithium chemistry. Lithium silicate has become the industry standard for premium polishing because the smaller lithium ion penetrates more deeply into the slab and produces more thorough densification with less residue. Application is typically by low pressure spray or microfibre mop at the recommended coverage rate for the slab porosity, with the densifier left to react and dry before the subsequent polishing steps proceed.

Coverage rates and application timing vary by product but follow predictable patterns. Most lithium silicate densifiers are applied at one to one and a half square metres per litre on a typical slab, with porous or older slabs needing closer to one square metre per litre to achieve the same level of densification. Multiple light coats are generally more effective than a single heavy coat because the densifier needs to penetrate rather than puddle on the surface. Application is typically scheduled between the 200 grit and 400 grit polishing steps, when the slab has been opened up enough to receive the densifier but not so highly polished that the surface is closed to penetration. Working with established Victorian polishers who have refined their densifier protocols for the local concrete supply produces more consistent results than generic application from product instructions.

Polish Levels and Gloss

Polish levels are referenced both by the number of grit steps in the sequence and by the gloss measurement at the finished surface. The American Concrete Institute publishes guidance on polished concrete classifications that has been broadly adopted across the Australian polishing industry, with Level 1 representing a basic ground finish through Level 4 representing a high gloss mirror finish. Level 1 is reached at 200 grit and represents a flat ground finish with minimal gloss. Level 2 is reached at 400 grit and produces a semi-gloss appearance suitable for standard residential and commercial floors. Level 3 is reached at 800 grit and produces a glossy reflective surface. Level 4 is reached at 1500 to 3000 grit and produces the high gloss mirror finish.

Gloss measurement using a 60 degree gloss meter provides an objective measure of the polish level. Level 1 typically reads below 30 gloss units, Level 2 reads 30 to 50, Level 3 reads 50 to 70, and Level 4 reads above 70 gloss units. Specifying the polish level by both the grit sequence and the gloss measurement provides clarity at quote stage and at handover. Many premium fitouts in Melbourne CBD retail and hospitality include a contractual gloss measurement at handover with rectification provisions if the measured gloss falls below the specified level.

Honed finishes provide an alternative to polished finishes for applications where a flat matte appearance is preferred over the gloss of a polish. Honing typically stops at 100 to 200 grit and does not progress through the densifier and polish sequence, producing a uniform matte surface with the texture of a soft natural stone. Honed concrete is increasingly popular for hospitality applications across inner Melbourne and bayside where the matte finish suits the design intent and provides better slip resistance than a high gloss polish. Honed finishes are typically priced at the lower end of the polished concrete band, often in the $80 to $130 per square metre range. For projects where the slab itself needs structural attention before honing or polishing can proceed, our concrete resurfacing guide covers the overlay options.

Sealing and Protection

Sealing of polished concrete differs from sealing other decorative finishes because the polishing process and the densifier already produce a surface with significant inherent protection. Many polished concrete floors are finished with a topical guard product applied as a thin film that increases stain resistance without affecting the gloss appearance, and these guards are renewed periodically as part of the maintenance regime rather than functioning as a replaceable sealer in the conventional sense. Other polished floors are finished with a penetrating impregnator applied through the densification process, leaving the surface looking entirely natural with protection working from within the concrete matrix.

Topical guard systems include products designed specifically for polished concrete, applied at thin coverage rates and burnished into the surface using a high speed buffer. The guard reduces oil and stain penetration significantly and extends the gloss retention through the wear cycle. Renewal is typically required every 6 to 18 months on commercial floors and 12 to 36 months on residential floors depending on traffic and cleaning regime. Penetrating impregnator systems include lithium-based and stearate-based products that line the capillary structure of the polished surface, providing stain protection without altering the appearance. Penetrating systems generally have longer service intervals than topical guards but provide slightly less aggressive stain resistance.

For polished concrete in food preparation, hospitality, and similar high-traffic stained environments, hybrid systems combining a penetrating densifier with a topical guard provide both deep protection and surface stain resistance. The hybrid approach is the standard specification for premium hospitality fitouts across Chapel Street, Smith Street, Brunswick Street, and Lygon Street where the floors face daily exposure to food, beverage, and high foot traffic. For lower traffic residential applications, a single guard or impregnator is generally sufficient, with the guard renewal scheduled into the homeowner's maintenance plan. Our concrete sealing guide covers the sealer technology in detail across decorative concrete categories.

Victorian Registration and Building Code

Polished concrete work on residential properties valued above $10,000 falls within the domestic building work definition where the polishing forms part of the construction or renovation of a dwelling, requiring the contractor to be registered with the Building and Plumbing Commission as a Domestic Builder under the Building Act 1993. Standalone polishing of an existing slab in a long-established home, particularly where the slab has been in service for years and is being polished for aesthetic upgrade rather than as part of a renovation, may sit outside the strict domestic building work definition and rely on general consumer contract law instead. Most homeowners benefit from engaging registered Domestic Builders or contractors working under registered builders because of the insurance and warranty framework that the registration provides.

Domestic Building Insurance is required for any domestic building contract above $16,000 and provides homeowner protection against the contractor's death, disappearance, or insolvency during the warranty period. The insurance is taken out by the builder and provided to the homeowner before any deposit is paid. Many polished concrete contracts above $16,000 fall within the requirement where the work forms part of broader construction activity. The Consumer Affairs Victoria guidance on domestic building contracts is the appropriate reference for any homeowner wanting to verify their rights before signing.

Building permit and planning permit considerations for polished concrete are limited because the work generally takes place inside an existing building shell or on a slab being installed under a separate building permit for the broader construction. Heritage listed properties and properties within heritage conservation areas across inner Melbourne and the regional heritage centres may have additional approval requirements where the polishing forms part of changes to a heritage interior, and the relevant council planning department is the appropriate first contact. The Victorian Government planning portal provides access to planning scheme information for any Victorian property. Site safety on polished concrete work, particularly the silica dust exposure during dry grinding, is governed by the WorkSafe Victoria framework which sets specific obligations on contractors handling crystalline silica and on the homeowners or builders engaging them. Crystalline silica health risks have been the subject of significant regulatory attention across Australia and HEPA dust extraction is no longer a premium specification but a baseline expectation for any reputable polishing contractor.

Slip resistance for polished concrete in commercial and accessible residential applications is governed by Australian Standards AS 4586 (slip resistance classification of new pedestrian surface materials), with polished concrete typically achieving classifications from P0 (least slip resistant, mirror polish) through P3 (moderately slip resistant, with applied slip-resistant surface treatment). Hospitality, retail, and commercial applications often specify minimum P3 classification under AS 4586, which is achievable on polished concrete through topical slip-resistant treatments applied to the polished surface or through inclusion of textured aggregate at the polishing stage. Where polished concrete forms part of a path of travel under disability access requirements, AS 1428 (design for access and mobility) applies alongside AS 4586. Polishing contractors working on commercial and accessible residential applications should confirm the slip resistance specification with the design team at quote stage and verify the achieved classification through independent slip testing at handover. The Australian Competition and Consumer Commission publishes consumer guidance on building contracts that applies to polished concrete works.

Polished Concrete Costs Across Melbourne

Melbourne pricing for polished concrete reflects three main factors. The first is the type of project, with new home polished slabs typically priced lower per square metre than retrofit polishing of older slabs because the new slab is purpose-poured for polishing. The second is the access and area, with large open commercial areas being most efficient and small residential rooms with cabinetry, narrow doorways, and tight corners costing materially more. The third is the polish specification including the gloss level, the aggregate exposure, and any dye or colour, all of which scale the project cost. The pricing tables below capture typical cost ranges for a 100 square metre area at the popular salt and pepper polish level across the main metropolitan zones.

The inner industrial belt running through Cremorne, Abbotsford, Collingwood, Brunswick, and South Melbourne is the heartland of Victorian polished concrete, with warehouse conversions to office, retail, hospitality, and residential apartments driving the strongest demand for polishing services. Many of these conversions involve polishing original 1950s through 1980s industrial slabs that were never designed for decorative finishing, and the variable slab quality across these older buildings is one of the defining challenges of inner Melbourne polishing work. Salt and pepper exposure is the dominant specification for these projects because cream finishes can highlight repair work and full aggregate exposure is rarely supportable on the older slab compositions. Premium hospitality fitouts through these precincts typically specify five step polish with topical guard and contractual gloss measurement at handover.

Bayside and inner east residential polished concrete pricing reflects the prestige residential market across Brighton, Hampton, Sandringham, Black Rock, Hawthorn, Camberwell, Kew, and Balwyn, where new builds and major renovations frequently specify polished concrete to the living areas and entry zones. The market for new build polished slabs in these areas typically uses 32 MPa concrete with white cement and selected fine aggregate, producing a clean finish that suits contemporary architectural design. Salt and pepper exposure with a five step polish is the most common specification, with the polish typically delivered around six to eight weeks after the slab pour to allow proper curing before grinding begins.

The west and south-east growth corridors represent the largest volume of new home polished concrete work in the state, with new builds across Tarneit, Truganina, Wyndham Vale, Point Cook, Manor Lakes, Berwick, Pakenham, Officer, Cranbourne East, and Clyde regularly including polished concrete in the kitchen, dining, and living zones. Pricing per square metre is consistently 10 to 20 percent below inner Melbourne for the same polish specification because the new build context provides simpler access, larger contiguous areas, and the slab can be specifically designed for polishing. The reactive Newer Volcanic clay subgrade across these corridors requires deeper crushed rock sub-base for the slab itself, and that allowance applies regardless of whether the slab will be polished or covered with another flooring system. For new slab work on growth corridor sites, our concrete slab guide covers the slab specification considerations.

Polished Concrete Costs in Regional Victoria

Regional Victorian pricing for polished concrete is generally 10 to 20 percent below Melbourne pricing, with the contractor pool more limited and travel costs becoming a factor for very remote sites. Most regional polishing work is concentrated around Geelong, Ballarat, Bendigo, the Surf Coast, and the Mornington Peninsula where there is enough new build volume and renovation activity to support local polished concrete specialists. More remote regional centres typically rely on contractors travelling from the major centres, with mobilisation costs added to the per square metre rate. Concrete supply for new pour polished slabs is sourced from Boral, Holcim, Hanson, Adbri, and regional independent batchers across Geelong, Ballarat, Bendigo, Shepparton, Mildura, Wodonga, Warrnambool, and the Latrobe Valley.

Geelong and the Bellarine Peninsula support a small group of dedicated polished concrete specialists serving both new home construction across Armstrong Creek, Lara, Curlewis, and Drysdale, and renovation work through the older Geelong waterfront and Newtown precincts. Surf Coast hospitality fitouts in Torquay, Anglesea, and Lorne represent a steady demand source, with cafes, restaurants, and surf retail commonly specifying polished concrete that suits the coastal contemporary aesthetic. Coastal salt exposure is generally less of an issue for polished concrete than for external concrete because the polished surface is internal, but ocean-facing buildings still benefit from sealer specifications appropriate to the elevated humidity and chloride exposure that affects internal floor surfaces over time.

Ballarat and Bendigo polishing markets are smaller than Geelong but are growing as the regional new home construction sector matures and as commercial and hospitality fitouts increasingly specify polished concrete. Local contractor capacity in both centres can be stretched during peak periods, and it is common for Melbourne polishers to travel to projects in either city when local capacity is exhausted. The frost considerations that affect external concrete pours in these locations do not directly affect polished concrete because the polishing is internal, but new slab pours that will be polished should still avoid frost risk during the curing period. The same applies across the Macedon Ranges, the Dandenongs, and the Yarra Valley where elevation produces winter frost risk.

Mornington Peninsula polished concrete pricing reflects the prestige residential market across Mount Eliza, Mount Martha, Sorrento, Portsea, Flinders, and Red Hill. Polished concrete is well established as a specification for new builds in these areas because the finish suits the coastal contemporary architectural style that dominates the peninsula market. Lead times can extend to eight to twelve weeks during peak periods through spring and early summer when construction activity peaks ahead of the holiday use season. For peninsula new builds where the slab is poured purposefully for later polishing, the slab specification (concrete grade, finish flatness, joint placement, curing protocol) needs to be coordinated with the eventual polisher rather than left as a default builder specification.

Inland regional Victoria offers the most affordable polished concrete pricing in the state, with local contractors in Shepparton, Wodonga, Mildura, Warrnambool, and the Latrobe Valley delivering quality work below metropolitan rates. Travel cost mobilisation can become a factor for very remote properties, and small projects below 50 square metres may not be economic for specialist contractors to travel to without combining with adjacent work. The contractor pool with full diamond polishing equipment is concentrated in the major centres, with the more peripheral regional areas often relying on grind-and-seal capability rather than full polish specification. For projects that need surface preparation before polishing can proceed, our concrete grinding guide covers the broader concrete grinding category, and where the slab needs structural attention before polishing, our concrete repair guide covers the rectification work.

What to Look For in a Polished Concrete Quote

A quality polished concrete quote in Victoria is a detailed document that itemises the area to be polished, the specified polish level (referenced both by grit sequence and by gloss measurement), the aggregate exposure level (cream, salt and pepper, or full aggregate), the densifier product, the topical guard or impregnator product, the inclusions and exclusions for slab assessment, crack and joint repair, edge work, surface protection during the work, dust extraction, and final cleaning. A quote without aggregate exposure and gloss specifications is incomplete because these are the variables that most directly affect both the appearance and the price.

Reference checks are critical for polished concrete because the appearance varies significantly with contractor skill and equipment, and the only reliable way to assess a contractor's capability is to inspect completed work. Ask each prospective contractor for the addresses of three to five completed polished concrete projects from the past two years that you can inspect, ideally including projects of similar age, size, and exposure level to your project. Check the consistency of the polish across the floor area, the cleanness of the edges and corners where the planetary grinder cannot reach, the joint and crack treatment, the gloss uniformity, and any visible repair work showing through the polish. Phone references from previous customers should focus on whether the finished result matched expectations, whether the schedule was met, and whether any defects were rectified without dispute.

Watch for quotes materially below the others in the field because the most common ways of cutting price on polishing are reducing the grit sequence (skipping intermediate steps which leaves visible scratch patterns), using sodium silicate densifier rather than lithium silicate, omitting the densifier altogether, applying a single light coat of guard rather than the recommended two coats, and inadequate edge work where machine grinders cannot reach. Each substitution reduces both the appearance and the durability of the finished floor. Ask for the densifier and guard product labels or data sheets to confirm the specification used, and consider gloss measurement at handover as a contractual requirement for premium projects. The Consumer Affairs Victoria guidance on getting quotes from tradespeople is the appropriate framework for any homeowner approaching this work.

Payment terms for polished concrete work should comply with the Domestic Building Contracts Act 1995 where the work falls within the domestic building work definition, with deposits limited to 10 percent above $20,000 contract value or 20 percent below that threshold, and progress payments tied to defined work stages. Independent stand-alone polishing work that does not meet the domestic building work definition is governed by general consumer contract law, but the same principles around staged payment, written contracts, and clear scope apply as best practice. Disputes that cannot be resolved between the parties can be escalated to the Victorian Civil and Administrative Tribunal which hears domestic building disputes alongside other consumer matters. For projects that require concrete coring through finished polished slabs for service penetrations, our concrete coring guide covers the diamond core drilling work, and for projects involving slab demolition and replacement before new polished work, our concrete removal guide covers the demolition logistics. The Australian Competition and Consumer Commission publishes consumer guidance applicable to building contracts including the polished concrete category.

Maintenance and Re-Polish

Polished concrete is a low maintenance floor compared to most alternatives but requires specific care to maintain appearance over the long term. Daily maintenance involves dust mopping or vacuuming to remove abrasive grit that would otherwise wear the polished surface. Wet mopping with a pH-neutral cleaner is sufficient for most spills and routine cleaning, with avoidance of acidic, alkaline, or harsh chemical cleaners that can etch the polished surface. Spot cleaning of spills should occur quickly to prevent staining, with most modern guard systems providing meaningful resistance to typical household spills.

Periodic burnishing using a high-speed buffer with appropriate pads renews the gloss between full re-polish events and is the typical maintenance cycle for premium retail and hospitality floors. Burnishing is typically scheduled monthly to quarterly for high-traffic commercial floors and annually for residential floors. The topical guard system is also renewed periodically as it wears, with renewal intervals of 6 to 18 months for commercial floors and 12 to 36 months for residential floors. Renewal involves cleaning the floor thoroughly, applying a fresh thin coat of guard, and burnishing it into the surface with the high-speed buffer.

Full re-polish is occasionally required where the floor has worn beyond the level that burnishing and guard renewal can address, or where the gloss has been damaged by inappropriate cleaning chemicals or physical damage. Re-polish typically returns to the appropriate intermediate grit step and progresses through the polish sequence again, with the densifier reapplied as part of the process. The re-polish is generally faster than the original polish because the heavy initial grinding does not need to be repeated, and the cost is typically 30 to 60 percent of the original polishing cost depending on the wear level. Most properly maintained polished concrete floors do not require re-polish for ten to twenty years, with the maintenance cycle of cleaning, burnishing, and guard renewal handling the routine care.

Damage repair on polished concrete is more difficult than on plain concrete because the polish itself is the finished appearance, and any repair patch typically does not match the surrounding surface without a significant blending grind. Small damage from impact or chemical etching can sometimes be addressed by spot polishing with hand-held diamond pads, but larger damage typically requires re-polishing the affected area along with adjacent floor to blend the repair. Cracks that develop after polishing can be filled with semi-rigid epoxy or polyurea but the filled crack will be visible as a contrasting line through the polished surface. The Domestic Building Contracts Act statutory warranty for major defects covers structural concrete defects for ten years from completion where the work falls within the domestic building work definition. For older polished floors that need surface refurbishment but not full re-polish, our concrete resurfacing guide covers the overlay options.
