There are two main forms of polished concrete:
GRIND & SEAL
A simple form of polished concrete which is a process of grinding the concrete to achieve the desired aggregate (stone) exposure then applying a topical sealer to achieve the desired level of shine and to protect the surface.
A smart choice for those looking to have polished concrete on a budget.
Mechanically polished concrete
The ultimate form of polished concrete. It is a process which uses various grits of diamonds, resins and chemicals to polish the concrete surface. Unlike topical sealers which can wear off, this system uses penetrating sealer which penetrates into the concrete. The shine is achieved by polishing the concrete itself, not by the sealer used.
Used as a high end and relatively maintenance free type of flooring. Perfect for both indoor and outdoor polished concrete.
Benefits of polished concrete
Extremely durable – Polished concrete is a permanent finish. Sealers deflect stains such as: oil, wine, dirt, etc
Enjoy the raw beauty of natural products
Concrete floors absorb heat from the ground below and from sunlight or air conditioning and retain the heat or cool for longer than many other floor finishes
No more grout to clean !!!
Unlike tiles, polished concrete does not have grout joins so cleaning is a breeze
Durable enough to last a lifetime, low maintenance cost
Vast range of finishes available to suit your style
The three main choices to make when choosing your specific polished concrete floor are:
- Procedure: Grind and Seal or Mechanically Polished Concrete
- Exposure: Nil, minimum or full aggregate exposure
- Finish: Matte, semi-gloss or high Gloss
Your personal preference is our guide to assisting you in attaining one of many looks that can be achieved with gloss levels to polished concrete floors – the matte finish is used for the more industrial/rustic look which is now being favoured by many interior designers wanting the raw material to work with furnishings and fittings in homes, shops, and other commercial spaces.
The semi-gloss is a popular choice, widely used as it doesn’t show up the dust as much as the high gloss, but still has a beautiful shine. The high gloss is for those who are looking for the wow factor and lends itself to the glamourous, high end areas. Although requiring a bit more maintenance as it can show when the floor is not spotless, this small point is outweighed by the incredible look of high gloss polished concrete finish.
Concrete Exposure Levels Explained
1. Original concrete surface
2. NIL EXPOSURE
Light burnish – Very little to no stone shows on the surface of the concrete. (This is difficult to achieve unless the concrete has been poured perfectly.
3. MINIMAL EXPOSURE
This is where there are small amounts of the stone visible on the surface – some areas may have no exposure and some may heavy. This is also referred to as a salt and pepper look and is achieved by just a light grind – approximately 2-5mm from the surface.
4. MAXIMUM EXPOSURE
This is where you can see all the stones on the surface and requires a heavy grind – usually, approximately 5mm below the surface.
