Polished Concrete Floors

At NZ Grinders we love polished concrete floors.

Polished Concrete is

  • Fashionable
  • Long lasting
  • Ideal for homes, warehouses, shops
  • Has a huge range of flooring options
  • Saves money over alternate flooring options
  • Easy to clean
  • Perfect for industrial and residential use
  • Ideal for heavy traffic areas
  • Waterproof

Polishing concrete  meets the council requirements of a +.45 slip coefficient factor. The slip resistance of a polish floor is no different than any normal flooring and in fact can be substantially higher with floors reaching as high as .8


Styling Polished Concrete Floors

Styles can also be produced into the concrete floor with etching, or a different colour, pattern, boarder at a particular area in the floor.

When outlining lines and etching, many designs can be invented that are very unique, but also detailed tile styles grids can be applied as well.

Custom-made signs or logos can also be put directly into the polished concrete floor, a terrific option on walk ways into retail and office stores.


Coloured Concrete

A wide array of colouring options are available. Colours can be solid and brilliant, or more translucent with lots of character producing a virtually marble-like floor.

Coloured concrete comes with all the same great benefits of other solid surface flooring but with the durability only concrete can make.


Environmentally-Friendly

Choosing coloured concrete over hardwood or carpets gives you a sustainable flooring options with many options in colour and texture. With other flooring options that are sustainable, eg some carpet fibre flooring, cork, bamboo etc, when they wear out they have to be placed in our land fills and replaced with more of the same products.

Using the concrete as part of the construction of the building, you have an eco friendly floor that will not wear out. Today these floors, when done right, provide the durability and stain resistance needed to last the life of the building. Also, polished concrete contributes no noticeable VOCs in the construction process.


Thermal Properties

Concrete floors use the energy of the sun and stored heat is released into the room. Heat from internal sources like fire places are also stored into the concrete. Under floor heating options vary and complement polished concrete.


Lighting

Increase of ambient lighting will enhance the warmth and beauty of your floor and reduce lighting costs. When this is used in supermarkets and warehouse environments there is noticeable energy savings.

 


 

FAQ

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. Want high end results? Then we have a list of preferred concrete contractors. Currently we are producing custom polished floors, ask us about this new and exciting process.

 

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.

 

What's the #1 reason for polished floors?

Depends on who it is for – let's take a quick look

Residential – For its aesthetics

Commercial and Retail – It's trendy and upbeat

Industrial – Maintenance and dust free

Green Construction – Eco friendly

 

Are there harmful VOCs?

No

 

Can rain damaged or old worn out concrete be polished?

Yes, watch us transform even poorly laid concrete into a polished work of art. Though poorly laid floors do not come up as good as concrete that has been placed for polishing, the results can still be good to excellent. We can fix even badly pitted or cracked concrete.

 

Is it slippery?

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.
