Floor grinding and polishing in Dubai: marble, terrazzo, granite and concrete

Updated 17 October 2026. Every rule in this guide links to its official source at the end of the page.

Key facts

• Slip resistance: measured by the pendulum test (PTV, BS EN 13036-4) under the Dubai Building Code's Table C.19.
• Indoor dry, level: PTV between 15 and 35; inclined surfaces of 5% or more need 35 or more.
• Outdoor and wet, level: PTV between 35 and 45; inclined surfaces of 5% or more need 45 or more.
• Pools, showers, pavements: PTV of 45 or more, accounting for both shod and barefoot users.
• No data, no acceptance: if a product has no PTV data, it should be laboratory tested before it is accepted.
• Dust and noise: silica dust needs respiratory protection; noise exposure is limited from 85 dBA over 8 hours, with hearing protection where it cannot be reduced.

Why stone and concrete floors lose their finish

Marble, terrazzo, granite and concrete are chosen for floors because they last decades. What changes is the surface. Fine sand carried in on shoes acts like sandpaper along walking routes, leaving dull traffic lanes; spills of acidic drinks, cleaners and food etch calcium-based stone such as marble; furniture and trolleys scratch; tiles settle and leave small height differences at the joints, known as lippage; and years of the wrong cleaning products leave films that trap dirt. In Dubai, where sand and dust reach every entrance, lobby floors and villa entrances show this quickly.

Restoration works on the surface rather than replacing the floor. Grinding removes the damaged top layer, honing refines it, and polishing brings back the finish the material was chosen for. Done properly, the floor looks new without demolition, and the work takes days rather than the weeks of a replacement.

Grinding, honing, polishing and sealing: what each step does

As guidance, a floor that is sound but dull may need only honing and polishing, while a floor with lippage, deep scratches or etching needs grinding first. A good assessment decides how far down the sequence the work has to start, which is the main factor in both the time and the cost.

Which floors can be restored

Before any quotation, as guidance, the material is confirmed on site, because similar-looking floors behave very differently under abrasives and chemicals.

Shine versus slip: the Dubai Building Code's slip resistance values

A high-gloss floor looks safe and expensive, but gloss and grip are different properties. The Dubai Building Code (2021 edition) measures slip resistance with the pendulum test value (PTV), using the method in BS EN 13036-4, and its accessibility part sets the values in Table C.19:

The code adds three points that matter directly for polishing. PTVs must take account of both shod and barefoot users. The product provider must give slip resistance parameters in PTV units, and if that data is not provided, the material should be tested in a laboratory before it is accepted. And wet areas such as toilets and swimming pools must have non-slippery floor surfaces. The code's definitions note that many floor manufacturers provide a PTV in their technical specifications.

As guidance, this is why the finish should be chosen by area, not by taste alone: a mirror polish may suit a dry living room or a showroom, while entrances that get wet, bathrooms, pool surrounds and outdoor terraces need a finish and, where appropriate, a treatment that keeps them within the code's values. Where slip resistance is in doubt after polishing, a pendulum test on site settles it.

Where in a building slip resistance matters most

As guidance, a single building can need three or four different finishes. Polishing contractors who treat every floor the same way, usually to the highest gloss, create the risk the code is written to prevent.

Floors that must be firm, smooth and stable

The code's accessibility rules also set geometry for floor surfaces. Floors must be firm, smooth and stable. Changes in level up to 13 mm are designed with a maximum 25% gradient, and changes greater than 13 mm are ramped or given a maximum 5% slope. Tiles with rounded edges and excessive joints should not be used on accessible routes, to prevent wheel vibration, tripping and noise, and where grates have longitudinal openings, they are installed with the openings perpendicular to the direction of travel.

As guidance, grinding is the tool that brings older tiled floors back into line with these expectations: removing lippage between tiles removes trip edges and the jolts that wheelchairs, prams and trolleys feel at every joint.

Dust and silica: protecting people during grinding

Grinding stone and concrete produces fine dust. Dubai Municipality's Safety Guide for Construction Works warns that dust containing silica particles can lead to severe health effects (silicosis), and requires workers who may be exposed to use adequate and suitable personal protective equipment, such as respiratory protection. The same guide requires workers who use respiratory protection to be physically able and medically determined qualified, with the medical examination repeated yearly, and requires PPE to be properly fitting, provided at the contractor's expense, kept clean in sealed bags when not in use, and used by workers trained by their supervisors.

As guidance, the best protection is not to make airborne dust in the first place: wet grinding or machines connected to industrial vacuum extraction with suitable filters, sealed-off work areas, and cleaning with vacuums rather than dry sweeping. In occupied buildings, dust control is also what keeps neighbours, furniture and air conditioning systems clean.

Noise: Dubai's permissible exposure limits

Floor grinders are loud. The construction safety guide sets permissible noise exposure levels by duration and requires contractors to provide ear protection where noise cannot be reduced to those levels by engineering controls, with workers trained to fit and maintain it; plain cotton is prohibited as hearing protection:

As guidance, in occupied buildings, noise also decides when work can happen: building management may set permitted hours for noisy works, so the schedule should be agreed with them before the job starts.

Eye protection and grinding equipment safety

The construction safety guide requires employees using grinding machines to be provided with safety goggles to protect their eyes against flying particles, and sets rules for grinding machines: abrasive wheels selected to withstand the spindle speed, closely inspected and ring-tested before mounting, with guards adjusted as the wheel wears. As guidance, floor machines follow the same logic: guards in place, discs and diamonds suited to the machine's speed, cables protected and connected through earth leakage protection, and the work area kept clear of other trades.

Working in occupied homes, offices and lobbies

Most floor restoration in Dubai happens in buildings that stay in use. As guidance, a well-run job protects skirting, walls, doors and furniture before starting; seals off the work area and keeps return air grilles and AC units nearby covered so dust is not drawn into the system; agrees working hours and access routes with building management; keeps a walkway open or schedules work by zones; and cleans up fully at the end of each day. Dubai Municipality's indoor air quality guideline asks for renovation work to isolate affected spaces from occupied zones, use the lowest-emission processes and materials, and use local extraction where polluting activities cannot be avoided, as explained in Power Zone's commercial building guide.

Sealers, coatings and indoor air quality

Sealers, coatings and some floor care products release chemicals as they cure. Dubai Municipality's indoor air quality guideline lists sealants, varnishes and lacquers, floor tile adhesives and cleaning agents among typical sources of volatile organic compounds such as formaldehyde, benzene and other solvents. As guidance, choose water-based or low-emission sealers where they meet the floor's needs, ventilate during and after application, keep occupants out of freshly treated areas for the period the manufacturer specifies, and avoid layering surface coatings on stone that only needs an impregnating sealer.

Polished concrete floors

Polished concrete is ground concrete, not a coating. As guidance, the process starts with coarse grinding to the level of exposure wanted, from a light cream finish with almost no aggregate showing to a full exposure of the stone in the mix; a densifier is applied to harden the surface; then progressively finer grits and polishing build the gloss, often finished with a guard or sealer against staining. Cracks and joints are filled before polishing. The result is a hard, dust-free surface that suits showrooms, offices, homes with a modern look and some commercial spaces, but its slip resistance must be checked against the code's values wherever the floor can get wet, such as entrances and terraces.

Marble: etching, scratches and lippage

Marble is the floor most often restored in Dubai villas, hotels and lobbies. As guidance, its common problems each need a different response: dull etch marks from acidic spills and the wrong cleaners need honing or grinding, because they are a chemical change to the surface; scratches need grinding to below their depth; lippage between tiles needs grinding flat; and stains in porous stone may need a poultice before sealing. A floor that only looks dull can often be honed and polished without grinding, which is faster and removes less material. After restoration, an impregnating sealer reduces staining but does not prevent acid etching, which is why cleaning products matter as much as the polish.

Terrazzo and granite

Terrazzo floors, common in older Dubai buildings, can usually be ground flat and polished like marble, with attention to cracks, old patch repairs and any brass or plastic divider strips. Granite is much harder and resists acids, so the work is usually about restoring a uniform shine, removing lippage and cleaning out grout lines rather than repairing etching. As guidance, both benefit from a site trial on a small area to agree the finish before the whole floor is done.

Choosing the finish: matte, satin or gloss

As guidance, the finish should be chosen together with the slip resistance the area needs under the Dubai Building Code. A practical compromise in many villas is a satin or gloss finish in dry living areas and a honed finish at entrances, kitchens, bathrooms and around pools.

Daily care and cleaning chemicals

As guidance, polished floors last longest with a simple routine: entrance mats inside and outside every external door to stop sand; dust mopping or vacuuming before wet cleaning; a pH-neutral cleaner made for stone rather than general-purpose acidic or alkaline products; spills wiped up quickly, especially acidic ones on marble; felt pads under furniture; and no abrasive powders or scouring pads. Cleaning products are also a source of indoor air pollution listed in Dubai Municipality's indoor air quality guideline, so choosing gentle products protects both the floor and the air. Power Zone's deep cleaning guide covers cleaning routines for whole properties.

How often floors need re-polishing

As guidance, there is no fixed interval: it depends on traffic, sand, cleaning and finish. A busy hotel or mall lobby may need routine buffing or crystallisation frequently and a full restoration every year or two, while a villa living room may go several years between restorations. The useful sign is the traffic lane: once a dull path appears along the main walking routes, a light honing and polishing restores it cheaply, while waiting until scratches and etch marks spread means grinding later.

Stairs, ramps and car parks

Stairs are where slips do the most harm, so the Dubai Building Code requires step edges with a slip-resistant surface and a light reflectance contrast of at least 30 points, and recommends warning surfaces at the descending edge of each flight. As guidance, polishing stairs therefore stops short of a high gloss on treads and keeps or restores contrasting nosings. For vehicular ramps, the code requires a broom-finish texture or an anti-slip treatment, so car park ramps are not polished smooth; car park floors elsewhere are usually treated for durability and cleaning rather than shine.

Pool decks and wet areas

Pool surrounds face the strictest values: the code requires PTV of 45 or more for swimming pools and showers, and pool decks of impervious, smooth, non-slip and easily cleanable material, at least 1.2 m wide and sloping 2% to deck drains. As guidance, restoring a stone pool deck is about cleaning, repairing and resealing while keeping or improving grip, never about adding gloss. Bathrooms follow the same logic: the code requires wet area floors to be non-slip, and stone in showers is honed rather than polished. Power Zone's pool maintenance guide and waterproofing guide cover the other parts of these areas.

Restore or replace: a decision guide

As guidance, tapping tiles to listen for hollow sounds and checking for moisture are part of a proper assessment. Polishing a floor whose tiles are losing their bond only hides the problem for a short time.

Lippage, joints, grout and cracks

As guidance, the joints often decide how a restored floor looks. Lippage is ground flat so the surface reads as one plane; open or crumbling grout lines are cleaned out and regrouted, ideally in a colour that matches the stone; cracks are filled with a colour-matched resin before honing; and expansion joints are kept clear and resealed with a flexible sealant rather than filled solid. Regrouting and tile repairs are listed on Power Zone's rate card, from grouting at AED 35 per m² to a bathroom regrouting job from AED 250, excluding VAT.

Common mistakes that ruin polished floors

As guidance, most of these cost nothing to avoid and save years of finish.

Wet weather and polished lobbies

Rain is infrequent in Dubai but, when it comes, polished lobbies and entrances become the most slippery surfaces in a building. As guidance, a building with polished floors keeps a wet-weather routine ready: extra absorbent mats at every entrance, warning signs placed at the doors, staff assigned to keep the first metres of the lobby dry, and attention to areas under canopies where water is blown in. The Dubai Building Code's requirement for higher slip resistance in outdoor and wet areas reflects the fact that these transition zones are where water most often reaches polished floors.

Testing slip resistance on site

The code's method is the pendulum test under BS EN 13036-4, which swings a rubber slider across the surface to measure the friction it meets, and gives a pendulum test value. As guidance, a site test is worth commissioning in a few situations: when a building is unsure whether a polished floor in a wet or outdoor area meets the code's values; after changing the finish or applying a coating; when the product used has no PTV data, which the code says should be tested before acceptance; and after a slip incident. Testing wet and dry, with the slider types used for shod and barefoot conditions where relevant, gives the full picture the code asks for.

Handover checklist after floor restoration

1. The finish matches the agreed sample in each area, with no swirl marks under raking light.
2. Edges, corners and thresholds are detailed to the same finish as the open floor.
3. Grout and joints are complete, clean and resealed where needed.
4. Sealer or densifier applied as specified, with the curing time and first-clean date written down.
5. Wet areas, entrances, stairs and pool surrounds have the finish agreed for slip resistance.
6. Skirtings, walls, doors and furniture are undamaged and protection is removed.
7. AC grilles and filters near the work area are checked and cleaned of dust.
8. Care instructions and the recommended cleaning products are handed to the owner or facility team.

Hotels, malls and offices: a floor safety plan

As guidance, large buildings with polished floors benefit from a written floor plan: a map of the finish in each area and the slip resistance it was chosen for, the cleaning products and methods allowed, the mat positions at each entrance, the wet-weather routine, the buffing or crystallisation schedule, and the interval for full restoration. It turns floor care from a cleaning crew habit into a managed system, and it gives the facility manager evidence of a considered approach if a slip ever has to be investigated. Power Zone's annual maintenance contract guide explains how such scheduled tasks are written into a maintenance contract.

Moving out, moving in: floors and the lease

Floors are a frequent point of discussion at the end of a tenancy. Dubai's Law No. (26) of 2007 requires the landlord to hand over the property in good condition that allows the tenant full use (Article 15), and requires the tenant, when the lease ends, to surrender the property in the same condition it was received, except for ordinary wear and tear or damage due to reasons beyond the tenant's control, with disputes referred to the Tribunal (Article 21). As guidance, dull traffic lanes on a marble floor after years of use are closer to ordinary wear, while deep gouges, chipped tiles or acid etching from careless cleaning are easier to argue as damage. Dated photos of the floors at check-in and check-out, and a restoration before handover, avoid most disagreements. Power Zone's villa maintenance guide explains the wider landlord and tenant duties.

Villas: room-by-room finishes

As guidance, these are starting points for a conversation with the owner, adjusted for the material, the family and how the house is used.

Protecting floors during fit-out and moving

As guidance, the cheapest restoration is the one that is never needed. Before any fit-out, painting or moving, polished floors should be covered with breathable protection boards or sheets rather than plastic that traps moisture, joints in the protection should be taped, furniture should be lifted rather than dragged, and trolleys should have soft wheels. Tape should never be applied directly to polished stone for long periods, because adhesive residues and trapped moisture can mark it. After the work, removing protection carefully and cleaning before any polishing avoids grinding sand into the surface.

Slurry, waste and drains

Wet grinding produces slurry, a mix of water, stone or cement fines and abrasive particles. As guidance, slurry is collected with wet vacuums and disposed of as construction waste, not washed into floor drains, gullies or sinks, where it settles like sand and blocks pipes and traps. Dubai Municipality's drainage rules treat sand as a problem worth trapping at source, requiring sand traps on property connections where needed, as explained in Power Zone's plumbing guide.

Children, older people and polished floors

As guidance, households with young children or older people benefit from choosing finishes with more grip in the areas they use most, keeping rugs secured with non-slip underlays, drying floors fully after mopping before anyone walks on them, and paying special attention to stairs, bathrooms and the route from bedroom to bathroom at night. The Dubai Building Code's accessibility values for slip resistance and level changes were written for exactly these users, so meeting them is a sensible standard even in a private home.

Polishing or coating: choosing between them

As guidance, some owners are offered a resin or epoxy coating instead of polishing. The two are different systems. Polishing works the floor's own surface and leaves nothing on top to peel; a coating adds a new layer that can be coloured and very easy to clean, but it can scratch, peel at edges or lose adhesion where moisture comes up through the slab, and it brings its own curing chemicals. For stone and good concrete in homes, lobbies and offices, polishing usually keeps the character of the floor; coatings suit areas such as stores, workshops and some plant rooms where chemical resistance or colour coding matters more. Either way, the finished surface still has to meet the Dubai Building Code's slip resistance values for the area, and coatings are among the materials whose emissions Dubai Municipality's indoor air quality guideline asks owners to consider.

Offices, showrooms and retail floors

As guidance, commercial floors are judged by appearance, downtime and safety together. Showrooms and retail often want a high gloss that shows products well, but their entrances, fitting rooms near wet areas and service corridors need more grip. Offices usually prefer satin finishes that hide wear between restorations. Work is normally planned out of hours or in zones so trading continues, with dust extraction and protection of displays and IT equipment. Building management approvals, permitted hours and access for equipment are agreed before the job, and the results are recorded in the building's floor safety plan.

Questions to ask a floor polishing company

1. Will you confirm the material and test a small area before quoting the whole floor?
2. Which steps will the job need: grinding, honing, polishing, sealing, and to what finish?
3. How will you control dust: wet grinding or vacuum extraction, and how will AC grilles and furniture be protected?
4. Do your workers use respiratory, eye and hearing protection as Dubai Municipality's construction safety guide requires?
5. For wet areas, entrances, stairs and pool decks, how will the finish meet the Dubai Building Code's slip resistance values?
6. Which sealer or coating will you use, and how long should the area stay unoccupied afterwards?

What affects the price

As guidance, floor restoration is priced by area and by how much work the floor needs: the material, the depth of damage (polishing a dull floor or grinding a damaged one), the finish level specified, edges, steps and detailing, moving furniture and working around occupants, and access and working hours in managed buildings. Power Zone quotes floor grinding and polishing after a site survey and an itemised quotation, with no fixed per-square-metre price. Related work on the Dubai rate card includes tile replacement from AED 100 per tile, grouting from AED 35 per m² and marble or stone installation labour from AED 150 per m², excluding VAT; see the Dubai rate card.

Floor grinding and polishing with Power Zone

Power Zone provides floor grinding and polishing across Dubai with its own teams, part of all seven emirates, 20 in-house teams, on marble, terrazzo, granite and polished concrete in villas, lobbies, offices and shops. Each job starts with a floor assessment covering the material, a damage map and the target finish, uses dust-controlled equipment and a staged progression from grinding to honing to polishing, includes edge detailing and sealing where the material needs it, and ends with protection of adjacent surfaces removed and a full clean-up at handover. See also tiling and grouting, villa maintenance and Power Zone Dubai, or request a site survey.

Frequently asked questions

How is slip resistance measured in Dubai?

The Dubai Building Code uses the pendulum test value (PTV) under BS EN 13036-4, with minimum values by area in Table C.19.

What PTV does a polished indoor floor need in Dubai?

Level indoor dry areas between 15 and 35 PTV; inclined indoor surfaces of 5% or more need 35 or more.

What PTV do wet areas and outdoor floors need?

Level outdoor and wet areas between 35 and 45 PTV, and inclined surfaces of 5% or more need 45 or more.

What PTV is required around swimming pools and in showers?

45 or more, accounting for both shod and barefoot users, under the Dubai Building Code.

What if a floor product has no slip resistance data?

The Dubai Building Code says providers should give PTV data, and if it is not provided the material should be tested in a laboratory before it is accepted.

Is grinding dust dangerous?

Dubai Municipality's construction safety guide warns that dust containing silica can lead to silicosis and requires suitable respiratory protection for exposed workers.

What noise limits apply to floor grinding work in Dubai?

Dubai Municipality's construction safety guide permits 85 dBA for 8 hours, falling to 15 minutes at 110 dBA, with ear protection where noise cannot be reduced.

Do grinding operators need eye protection?

Yes. The construction safety guide requires safety goggles for employees using grinding machines.

What is the difference between grinding and polishing?

Grinding removes damaged surface and lippage with coarse abrasives; honing and polishing then refine the surface to the finish specified.

Can etch marks on marble be polished out?

As guidance, etching is a chemical change to the surface, so it usually needs honing or grinding rather than polishing alone.

Can porcelain tiles be polished?

As guidance, porcelain and ceramic tiles are generally not ground; they are cleaned, regrouted or replaced instead.

Should bathroom stone floors be high gloss?

No. The Dubai Building Code requires wet area floors to be non-slip, so stone in bathrooms and showers is usually honed rather than polished.

Can stairs be polished to a high gloss?

As guidance, no: the code requires slip-resistant step edges with a 30-point light reflectance contrast, so treads keep a safer finish.

Do sealers affect indoor air quality?

Dubai Municipality's indoor air quality guideline lists sealants, varnishes, lacquers and cleaning agents among sources of volatile organic compounds; ventilate and follow the curing time.

How often should marble floors be re-polished?

As guidance, when a dull traffic lane appears along walking routes; busy lobbies need it far more often than villa living rooms.

How much does floor polishing cost in Dubai?

Power Zone quotes after a site survey; price depends on area, material, damage depth, finish, edges, furniture and access.

Should I restore or replace a stone floor?

As guidance, restore sound floors that are dull, scratched, etched or uneven; replace cracked or hollow tiles, and investigate and relay floors with failed bedding or moisture.

How is slip resistance tested on site?

With the pendulum test under BS EN 13036-4, which the Dubai Building Code uses; as guidance, test wet and dry, and after changing a finish or applying a coating.

What ruins polished marble fastest?

As guidance, acidic or general-purpose cleaners, dry sweeping sand, missing entrance mats and dragging furniture.

Is a dull marble floor the tenant's responsibility at move-out?

Law No. 26 of 2007 excepts ordinary wear and tear from the tenant's duty to return the property in the condition received; as guidance, dull traffic lanes are closer to wear, while gouges and etching from careless cleaning are easier to argue as damage.

Can grinding slurry go down the drain?

As guidance, no: slurry is collected with wet vacuums and disposed of as construction waste, because it settles like sand and blocks drains.

Is epoxy coating better than polishing concrete?

As guidance, they suit different uses: polishing works the floor's own surface and cannot peel, while coatings suit stores, workshops and plant rooms; both must meet the code's slip resistance values.

Can floor polishing be done outside business hours?

As guidance, yes: commercial floors are usually done out of hours or in zones, with building management approving hours and access.

How long does floor polishing take?

As guidance, it depends on area, material and damage; restoring a sound floor takes days rather than the weeks a replacement needs, and grinding adds time.

Can I walk on a floor straight after polishing?

As guidance, usually yes for polishing alone; after sealing or densifying, follow the manufacturer's curing time before heavy use or wet cleaning.

What is a densifier?

As guidance, a liquid that reacts with concrete to harden the surface before polishing, making it more resistant to wear and dusting.

Do polished floors need mats?

As guidance, yes: mats inside and outside every external door stop the sand and water that dull and endanger polished floors.

Do polished stone floors need sealing?

As guidance, porous stone such as marble and some limestones benefit from an impregnating sealer against stains, while dense granite may need little; a site test decides.

Can terrazzo be restored?

As guidance, yes: terrazzo can usually be ground flat and polished like marble, with care at cracks, old patches and divider strips.

Does Power Zone polish marble and concrete floors in Dubai?

Yes. Power Zone grinds, hones, polishes and seals marble, terrazzo, granite and concrete across Dubai with dust-controlled equipment and its own teams.
