Here's everything you need to know about concrete polishing costs to help you make informed decisions.





Are you considering polished concrete floors for your home but feeling overwhelmed by the pricing options?

We're here to break down everything you need to know about concrete polishing costs and help you make informed decisions. Let's dive in.


Understanding Concrete Polishing Prices

Several factors determine the cost of your polished concrete floor, ranging anywhere from $25 to $100 per square metre. The technique used to polish the concrete significantly impacts the price.

  • The grind and seal method is the most affordable, averaging about $50/m2.
  • If you want a honed finish, you're looking at around $75/m2.
  • For a top-of-the-line mechanically polished floor, expect to shell out around $100/m2.

The size and condition of the floor in your home also come into play when calculating cost.


Examining Concrete Polishing Techniques

While you're considering the concrete polishing cost, it's also important to understand the different techniques used and how they impact both the price and the final result.

These include:

  • Grind and seal: This is the least expensive method, but it requires re-application every 5 to 10 years.
  • Honed concrete: A bit more costly, this technique provides a smooth, matte finish.
  • Mechanically polished concrete: The priciest option. It's long-lasting and ideal for high-traffic areas.


Step-by-Step Concrete Polishing Process

Knowing the process of concrete polishing can help you customise and make informed decisions about your flooring project.

  • Step 1: Professionals use special machinery with diamond or silicon sandpaper to grind down your concrete floor. This initial grinding creates a smooth surface that's ready for the next steps.
  • Step 2: Finer grits of sandpaper are used for the actual polishing. This process is meticulous, requiring different machines for corners and detailed areas. If you're opting for the grind and seal method, at least two grades of sandpaper are needed.
  • Final step: This involves sealing your floor, giving it a matte, satin, or high gloss look. You can even add colored aggregate or create patterns for a truly unique finish.


Exploring Polished Concrete Effects

The aesthetic versatility of polished concrete is truly impressive, and there's a wide range of effects and finishes to choose from.

  • Matte, Satin, or High Gloss: The degree of shine is up to you. A high gloss finish reflects light beautifully, while a matte or satin finish gives a softer, more natural look.
  • Shades of Grey: From nearly white to charcoal, the spectrum of greys is vast.
  • Coloured Aggregate: For a pop of colour, consider adding coloured aggregates.
  • Patterned Designs: By using different colours or aggregates, unique patterns can be created.
  • Sealer Finishes: Like the concrete itself, sealers can be matte, satin, or high gloss.

With polished concrete, the possibilities are endless. Explore, experiment, and find the finish that best suits your home.


Getting Accurate Polishing Quotes

You will need quotes from reputable concreters or concrete grinding services and take into consideration both the price and the quality of the work. Don't be tempted to simply opt for the cheapest option.

Compare quotes carefully. Look at the breakdown of costs and ensure you understand exactly what you're paying for. Ask for examples of their work and request references. This way, you're not just taking their word for it.

Costs can also vary locally due to market forces, so consider this when reviewing your quotes.


Selection of Concrete Polishing Method

Your options include the grind and seal method, honed concrete, and mechanically polished concrete. Making the right choice involves considering several factors:

  • Cost: Grind and seal is the least expensive, while mechanically polished concrete is pricier.
  • Longevity: Mechanically polished surfaces last longer, especially in high-traffic areas.
  • Maintenance: Grind and seal floors require refinishing every 5 to 10 years.
  • Appearance: You can customise and choose between matte, satin, or high-gloss finishes.
  • Installation: Special machinery and expert skills are needed for concrete polishing.


Choosing the Right Concrete Finish

When selecting a concrete finish for your home, consider the following factors:

  • Style: Your preferred aesthetic will guide your choice. Polished concrete can range from a matte to high gloss finish.
  • Budget: Polished concrete costs can vary significantly depending on the chosen finish and process.
  • Maintenance: Different finishes require varying levels of upkeep. Some may need refinishing every few years.
  • Durability: High-traffic areas may require a more durable, mechanically polished finish.
  • Installation: Some finishes may require more complex installation processes, affecting the final cost.

Understanding concrete polishing costs doesn't have to be complex. By exploring different techniques, understanding the process, and knowing what effects to expect, you're now equipped to get accurate quotes.

Your choice of polishing method and finish impacts the final price. With proper maintenance, your sleek, polished concrete floors can be a worthy investment.
