What is polished concrete?
Think of polishing concrete as refining the concrete surface with a grinding and polishing action to give hard, dense, thermal gains, stain resistant, very easily cleanable and long lasting floor. There is NO coating applied, so nothing to chip or peel or discolour.

There is a stain guard protection chemical system applied similar to how polish is applied for a car paint job. Our systems are fully waterproof which means no staining from red wine and the likes.
How is the concrete polished?
You start with coarse blades attached to a grinder 400+ kg in weight (smaller grinders work but in some cases they do not produce stone if the concrete is too hard) to take away layers at a time to produce the chosen stone content e.g salt and pepper (fines only) or full stone etc. Once this is established and all imperfections are fixed, the polish process takes place with finer diamonds to produce polished concrete from 400 up to 3000 diamond finish. Chemicals and concrete protection systems are added to change the chemical structure of the concrete to give hardness and stain protection, partial or full.
Is it important how the concrete is laid?
It is everything to the concrete polished job. Poorly laid concrete will result in a less than ideal polish job. A good concrete layer is totally complementary to a concrete grinding company.

Is all concrete polishing the same?
No, definitely not. Good machinery, techniques and a wealth of knowledge is the key to an un-beatable high end finish. All our systems carry a 10 year warranty. If you want your floor to carry its shine year after year then it is important that steps are not skipped in the polishing process.
Can concrete polishing be water proof?
Yes. There are new polished chemicals that give waterproofing and stain control against oils etc. Every system is different and gives different levels of protection for polished floors. These systems soak into the matrix of the concrete and form micro umbrellas that stop ingression of liquids.
Is coated concrete or grind and seal the same?
No. Coatings are topical. Another words, they sit of the surface. You’re looking at a coating that is covering the concrete. Polished concrete is about refining the surface. Coatings typically scratch over time. The finish of polished concrete is so super fine that tyre marks don’t stick. Coatings are generally cheaper as they do not require precision grinding.

No. All our floors meet council co-efficient slip rating
How long will it last?
It is a permanent process, there is no wax or coatings applied that will eventually fail. When we are finished with your floors it is bare concrete that has been permanently polished. General cleaning will keep the floors looking amazing, year after year. In high traffic areas simple buffing can be done along side the general cleaning but this will be less frequent. A re-application of polish can be applied also at any time, this is similar to polishing a car's paint job.
How much does concrete polished floor cost per SQ/M?
Largely dependent on the size of the job and other factors the price can vary. Generally if you’re expecting a full grind to stone job of distinction then look at prices from $50 to $130 per SQ/M for domestic finishes as this requires more attention to detail thus having a higher labour content. Detail is given to edges. Larger size areas such as warehouses etc are different in price and can be considerably cheaper. We price of the plan or a SQ/M- every job is different, email us and we will respond with a price within 24hours.
How do we know we are getting quality?
Ask for a certified contractor and ask to see their credentials. Craftsmanship combined with quality grinding and polishing machines will produce excellent results.
At what stage should the polishing be done?
Depending on what finish we need to do the first 4 steps normally before frames go up around day 6. If this is not possible then before the gibbing. The later steps are done at the end of painting or end of gib stopping before skirting. In the likes of commercial then we normally are one of the last contractors. Salt and pepper finishes are done after framing.
What should I expect with Polished Concrete?
Polished concrete will deliver a hard, durable, easily cleanable floor.
