FAQs

What Is Concrete Grinding?

Concrete grinding is a mechanical process used to smooth, level, and prepare concrete surfaces by removing imperfections, coatings, adhesives, or uneven areas.

What Is Concrete Grinding Used For?

Concrete grinding smooths, levels, and prepares slabs by removing defects, enabling safe, durable flooring installations. It is commonly used to correct uneven surfaces, remove coatings or adhesives, eliminate trip hazards, and prepare concrete for polishing, sealing, coatings, or new flooring systems.

How Do You Grind And Polish Concrete Surfaces?

Concrete grinding and polishing are completed using specialised floor grinding machines fitted with rotating diamond tooling. As the machine operates, industrial-grade diamond segments work the concrete surface at high speed, gradually refining it to the required level.

Different diamond tools are selected depending on the condition of the slab and the desired finish. Coarser diamonds remove surface imperfections and uneven areas, while finer-grit diamonds progressively smooth the concrete.

What Concrete Surface Profile (CSP) Is Needed For Coatings And Polishing?

A concrete surface profile (CSP) describes the texture of the slab after grinding — it determines how well coatings or polished finishes bond. For most thin-film coatings and epoxy systems, a CSP in the range of 2 to 3 is recommended so primers and adhesives have a mechanical ‘key’ to grip. Incorrect profiling can cause peeling, blisters or poor adhesion.

What Are The Benefits Of A Grind And Seal Floor Finish?

A grind and seal system enhances the appearance of concrete while providing a durable, protective surface layer. This process creates a smooth, even finish that is easy to clean and maintain when correctly applied and cared for.

The protective coating helps resist wear, dusting, tyre marks, moisture, oils, chemicals, stains, heat, and abrasion. Finishes can also be tinted to suit design requirements, making grind and seal an attractive and practical solution for residential, commercial, and industrial spaces.

Can You Repair Our Existing Concrete Floor?

Yes, our specialists assess the condition of your concrete before work begins. After grinding your floor, we can repair cracks, concrete cancer, spalling, and surface defects to refinish the slab and restore a durable, like-new concrete finish suitable for sealing, coating, or polishing.

How Does Dust Control Affect Health, Compliance And Site Conditions?

Concrete grinding generates fine silica dust that, if uncontrolled, can be harmful to workers and occupants and may breach workplace health and safety regulations. Professional dust control is essential to protect respiratory health, maintain clean site conditions, and ensure compliant concrete surface preparation.

Our concrete grinding services are performed using dust-controlled grinding equipment connected directly to industrial dust extraction systems. These systems capture airborne dust at the source as grinding occurs, significantly reducing the spread of fine particles throughout the work area.

Effective dust control allows concrete grinding to be safely carried out in residential, commercial, and indoor environments while maintaining surface quality, protecting surrounding finishes, and supporting compliance with relevant health and safety guidelines.

Why Should I Hire A Professional For Concrete Grinding Instead Of DIY?

Concrete grinding requires specialist machinery, training, and safety controls that DIY equipment cannot replicate. Professionals assess slab condition, select the correct tooling, manage dust control, and avoid surface damage or personal injury. Hiring a qualified operator ensures even results that meet finish or coating requirements and reduces long-term costs.

How Much Does Concrete Grinding Cost Per Square Metre?

Concrete grinding costs vary depending on slab size, surface condition, coatings, and the required finish. In most cases, concrete grinding costs range from $10 to $90 per square metre, depending on the scope of work and site conditions.

How Long Does Grinding Take?

Most concrete grinding projects take anywhere from a few hours to a few days, depending on surface size, concrete condition, coatings, and the required finish. Small residential areas can often be completed in one day, while larger commercial projects may take several days or longer.
