Diamond polished concrete is a premium concrete floor finish that combines elegant aesthetics with unmatched durability and low maintenance — ideal for homes, businesses, retail, warehouses, and industrial spaces. This finish transforms ordinary concrete slabs into hard‑wearing, glossy, high‑performance floors that reflect light, improve indoor brightness, and reduce energy usage.
Polished concrete is unlike any other floor surface, offering the perfect balance of beauty and practicality. Diamond polished concrete floors are energy-efficient, reflecting light and heat to reduce energy consumption while remaining solid, durable, and low-maintenance.
There are two main types of polished concrete, which differ significantly. Companies often use alternative names for each other. The most common types are:
- Grind and Seal (also known as traditional polished concrete)
- Diamond Polished Concrete (also known as Pyrafloor, Hiperfloor, Superfloor, natural polish, etc.)

Why Choose Diamond Polished Concrete?
What makes it different? Diamond polished concrete is created by grinding concrete with progressively finer diamond abrasives and densifiers to produce a smooth, reflective surface — not by applying a surface coating. This gives floors incredible hardness and shine without peel or chip. Diamond polished concrete is versatile and suitable for small and large commercial environments, as well as family homes. Its smooth, sealed surface prevents the trapping of mould, mildew, dust mites, bacteria, allergens, or moisture, making it ideal for anyone with allergies, asthma, or other respiratory issues.
This signature finish brightens any space and has been successfully used in galleries, homes, shopping centres, retail shops, and factories, complementing any décor.
Important: Polished concrete isn’t ideal for every area. Bathrooms and wet areas must be approached differently. Multiple concrete pours may increase costs, so planning ahead is crucial.
Design Freedom: Colours & Finishes
Before pouring new concrete, consider the following:
- Concrete Colour – Can be added either in the mix at the batching plant or as a stain after installation. We recommend mixing colour into the concrete for consistency and UV stability.
- Aggregate/Stone Colour – Choose in consultation with your concreter and supplier. Samples vary between suppliers and batching plants.
- Concrete Strength – For diamond polished concrete, a minimum of 32MPa is recommended for durability.
Main Finishes
Diamond polished concrete offers three main finishes:
Burnished/Cream Polish – Only the surface is polished; no stone is exposed. Think Bunnings floors.
Partial Stone Exposure – Also called "hit n miss" or "salt & pepper." Some areas show more stone than others, creating a random pattern. Typically, 1–3mm of concrete is ground to achieve this look.
Full Stone Exposure – The floor is ground until stone is evenly exposed. Sometimes necessary if the concrete isn’t level. Up to 5–10mm may be removed, so careful height planning is required.

Gloss Level & Slip Rating
Diamond polished concrete can be finished in matte, satin, or gloss. We recommend satin or higher for optimal light reflection.
- Residential Floors: Slip rating is generally less of a concern.
- External Floors: Honed finishes are used for non-slip properties.
- Commercial Spaces: We can achieve P1–P5 slip ratings. Let us know your requirements to ensure proper finishing.
