Concrete polishing is an art in itself, having the experience and the right human touch. Polished Concrete has become one of the fastest growing green building flooring products for use in commercial, residential and industrial
Mechanically Polished Concrete System are low-maintenance, as they are more durable and easier to clean than many flooring options.
The grinding tools are usually progressive grits of diamond grinding shoes attached on the bottom of a heavy grinders and polishing resin pads. Concrete is not considered polished before 400 grit, and it is normally finished to either the 800, 1500 grit level.
There are many advantages of having polished concrete floors on your project.
Beauty: Polished concrete floors are mirror-like.
Clarity: Increased ambient lighting which will naturally enhance the beauty of your floor and reduce the cost of lighting.
Stain Resistant: Transformation of porous concrete into a dense surface that inhibits water, oil and other contaminants from penetrating the surface.
Slip Resistant: Higher levels of co-efficient of friction than any coating on the market. Polished concrete floor surfaces meet Australia standards for slip resistance.
Scratch resistant: Elimination of tire marks from fork lifts, vehicles and industrial type hoppers. This doesn’t occur on a polished concrete floor as there are no resins to burn on the surface.
Cost-Effective: Polished concrete is one of the most economical, cost effective flooring alternatives out there. The reduced costs associated with saved energy, reduced tire wear, maintenance reduction, and especially the long-lasting durability.
Maintenance free & easy to clean: A concrete polished floor doesn’t require this intense scrubbing — the surface is so tightly compacted that it actually repels oils and other substances. This makes cleaning much easier and a maintenance schedule less demanding than with other floors.
Sustainable: Unsurpassed durability compared to other flooring products Polished concrete is intrinsically green because it dematerializes a project, reducing the need to bring in additional coverings or coatings that end up in land-fills upon their eventual replacement.
Longest Lasting Floor Available: There is simply no comparison to other floor systems when it comes to the life of a polished concrete floor. Polished concrete floors will be there as long as the slab exists.
Nil Exposure: No exposure of aggregate at all. For this finish, the slab must have no screed marks or flaws, as it will be visible. The concrete slab must be flat and high burnished to achieve a professional finish. The helicopter must be use as much as you can to burnish the surface, the concreter needs to get close to the edges as possible to get an even finish everywhere. Concrete needs to be cured ver well, no less than 32 mpa.
Salt and Pepper: This finish exposes just a small quantity of aggregates. The concrete needs to have no less than 25 mpa. Salt and pepper polished concrete finish can be finished with a matte, satin or high gloss Finish. To achieve a salt & pepper finish, the concrete needs to be in reasonable condition, as we just light grind the top to expose small quantity of aggregates. It’s a very popular choice for restaurants, coffee shops and retail.
Full exposure: This finish is absolutelly stunning, where the aggregates will be exposed completelly. The concrete needs to have no less than 25 mpa. This concrete finish can be achieved with a remarkable consistency of aggregate density if the slab is prepared by an experienced concreter. Different colours and sizes of agregates can be added on a brand new project.
Hiperfloor: The floor is ground, and a slurry is mixed to fill the pin holes and cracks. Floor Hardener is applied in between polishing grits, and then the penetrating sealer is applied on the final step.
Grind And Seal: The floor is ground to the desired stone exposure level, and then a polyurethane water based sealer is applied twice. Grind and seal is suitable for indoor and outdoor.
Honed Concrete: The floor is ground, and a penetrating sealer is applied, giving the concrete a natural look. Honed Concrete is also slip resistant and is suitable for external finishes.
Polished concrete floor system can take 5 to 7 days start to finish. The full process have between 9 & 14 steps.
Grinding: The concrete floor is ground with heavy planatery grinders using metal bond diamonds. A deeper grind will result in greater aggregate exposure and a better flat finish floor. Some client will choose no aggregates exposed.
Hardening: Concrete Hardening is the process by which the concrete surface is solidified. Obtained by a chemical reaction between a liquid concrete hardener and the concrete surface. The outcome of this process enables the concrete surface to be polished at higher grits.
Grouting: Concrete grouting is used to minimize the concrete surface porosity. Grouting process will fill all the small holes or cracks on the floor, The concrete slab dust plus the grouting system will fill the holes matching the same colour as the concrete slab.
Polishing: Concrete polishing is the process using resin pads. The purpose is to create a smoother and high polished surface, so enabling light to reflect. The higher & finer the polish grit is, the greater the light and sheen will be.
Sealing & Buffing: Concrete sealing and buffing are the process which the surface is protected with penetrating sealers, which are stain resist, and a buffer is used to high polish the floors.
