Polished concrete floors are gaining popularity as flooring material for commercial, industrial, and residential buildings. This is a flexible and low-maintenance choice when people want to have the flooring installed for interior or outdoor concrete floors, old or new, with various gloss levels and aggregate exposure to choose from. 

While polished concrete flooring costs depend on many factors, it ranges from $50 to $100 per square metre (sq m) in Australia. However, the fee may be lower if you already have existing concrete flooring and only need a simple polish. This simple price guide can help you budget for your concrete polishing project.

Grind and seal

A grind and seal method involves grinding the top layer and sealing it with a matte or gloss sealant. It can be used indoors and outdoors and is popular for garages, driveways, shops, restaurants, bars, homes and offices.

Honed concrete

This type of polish leaves a smooth and even matte finish after grinding. Honed concrete is commonly used around pools, pathways, driveways and outdoor entertainment areas in a home.

Mechanical polish

This process involves grinding, hardening, and then polishing. Mechanical polish typically has a high-end finish and is recommended indoors only.

Factors affecting the cost of polished concrete floors

Location

The pricing depends on where you live. An average square metre of polished concrete in Melbourne costs $50. Queensland residents may expect to pay around $65 per square metre for the same polished concrete services.

Room size and accessibility

Larger rooms have higher material and labour costs. For instance, polished concrete garage floor costs can be higher than finishing a simple bedroom. But, even small rooms or spaces like bathrooms that don’t require a lot of materials can be challenging due to access issues and complexity. 

Excavation depth

Providing a stable foundation when constructing a new concrete floor is critical to prevent subsidence and cracking. Building a foundation requires removing the existing base and excavating the underlying ground. 

Because the local geology, soil characteristics, and water table can vary, the excavation depth can only be established once the excavator reaches stable subsoil. The deeper you dig, the more soil you need to remove and concrete you must use. As a result, the depth of the excavation significantly impacts the average cost of polishing concrete floors.

Floor condition

How the concrete floor foundation is rebuilt depends on the type and state of the existing floor. If the foundation of some old concrete floors remains solid, you may only replace the concrete. A timber-suspended floor, in contrast, will need to be completely removed, followed by the installation of new floor foundations. 

Finish

You can dye your polished concrete flooring to match your interior. Polishes and sealants will lengthen the concrete’s lifespan and make it easier to maintain a clean surface. All of these, however, raise the overall costs of polished concrete floors.

Benefits of polished concrete floors

You might be wondering what you will gain by installing concrete floors. Here are a few benefits you might enjoy:

  • Requires little maintenance. Concrete floors that have been polished will maintain their quality for a very long period. These floors require routine sweeping or vacuuming, washing, and drying. Periodically, use a high-quality sealer to reseal the surface.

  • Your property will look stylish, contemporary, and modern. Polished concrete can be stained or dyed in different colours. You can paint a polished concrete floor with a light colour that will reflect light. This isn’t only visually pleasing but can also cut your energy costs because it lets light travel across the space more efficiently; thus, less indoor lighting will be required.

  • Doesn’t retain dirt. By selecting the right sealer, the floors will be waterproof, stain-resistant, and non-slip. 

  • More cost-effective. Polished concrete is less expensive than hardwood, marble, tile, and other floor coverings. Moreover, unlike most other flooring options, polished concrete doesn’t become damaged by mould or moisture. This type of flooring is also perfect for underfloor heating.

FAQs about polished concrete flooring

While it depends on the length of work, the average timeline is usually around three days. However, you must also take into account the curing process. So be prepared to add another 14 days to the total process. But note that curing will progress or regress depending on the current temperatures.

On average, polished concrete floors last about 20 years. The rule of thumb here is to make sure you take care of your things. Whether perishable items or furniture, you can prolong their life span if you manage them well. 

Between the cost of polished concrete floors versus tiles in Australia, the former is more expensive per square metre. But against hardwood, polished concrete flooring has material costs that are significantly lower than high-quality hardwood floors. 

All concrete floors will eventually crack, whether polished, coated, or left untreated. Concrete slab fractures as part of the initial curing process and will crack again over time. By sawing joints into the floor’s surface, cracks can be partly controlled and filled and sealed to stop additional damage.

Even when wet, polished concrete provides great slip resistance. Water’s interaction with the porous surface can even give shoes a little extra traction. However, water doesn’t wipe away as quickly on polished concrete’s porous surface, leaving a brief damp area. Spilt oils and chemicals can still cause slip risks and other safety concerns, as with many different types of flooring. 

Installing a more durable chemical-resistant floor coating may be your best option if you need flooring for commercial use or a manufacturing facility that works with oils or corrosive chemicals.

It’s best to seal concrete every two to five years to keep it in good condition and avoid cracking, pitting, and further damage.
