The time it takes to polish concrete depends on a few factors – firstly how big the area is, and also if the space is open or if there are lots of small rooms that require extra hand work. Then depending on which concrete polishing system you want – full polish or grind and seal, then how much exposure of stone or aggregate you want to see, and the level of shine or gloss you want. As an example a normal garage for a grind and seal takes approximately 2 days. And a house that has approx 100m2 of full exposure and polish takes about 5-6 days.
CGP quote at a per square meter rate, and the price will depend upon the procedure – full mechanical polish or grind and seal, level of exposure, condition of the concrete etc. It is best to contact us for a quote.
If you want to polish the concrete of an existing slab, then you are limited to whatever is already in the concrete. If you don’t like the colour of the cement and aggregate, the only option is to put a colour dye over the top.
If you are pouring a new slab you can choose the colour of your cement and the colour of your stone (aggregate). It is important not to underestimate the colour of the cement, as this can significantly change the look and the cost of the floor.
When doing the main grind there is very minimal dust in the air as we use high grade three phase dust extractors. . After each step during the procedure the floor is cleaned and on completion there is no mess or dust to be seen.
Yes, its possibly the best solutions for you. Polished concrete floors are completely seamless and will not support the growth of toxic mould, dirt, pollen or dust mites and therefore are perfect for any sufferers of asthma or other allergies.
The best way to keep your polished concrete in good condition is to use a ph neutral cleaner followed by clean hot water for spills, most detergents and floor cleaners are fine just do not use any hard abrasive chemicals such as acids etc. If in doubt always do a test area first. Otherwise a microfiber mop will get rid of dust.
CGP uses a sealer on all our finishes which prevents staining. However we do recommend that spills are cleaned up quickly.
Generally speaking it is no more slippery than other hard flooring surfaces. CGP recommend, for outdoor use, to do the grind and seal procedure. This way we can add an anti slip agent to the sealer. We can adapt the anti-slip to suit your needs.
Yes it is possible, but we would recommend doing a grind and seal instead of a full polish for a few reasons. With the grind and seal the topical sealant will be water tight so no water penetrates into the concrete and can also be made slip resistant if required.
As a general rule the concrete should be cured for 28 days before we can do any grinding. Then we can do the polish all at once or in two stages. If we are to do it in one stage we come in after the frame is up and the roof is on. Or we can do it in two stages which requires us to come in and do an initial grind prior to the frame going up, then we put on a protective coating until works have been completed, then we remove the protective coating and polish up the floor.
No, CGP specializes in the polishing or grinding, however we do have some concreters that we work closely with that we can recommend to you as it is very important to be involved with the right contractor from an early stage so the whole process
Generally Yes. Mechanically full polished floors can be repaired in small areas, however with a grind and seal the entire areas usually need to be done to avoid different colours through the concrete.
runs smoothly and you end up with a breathtaking floor
There has been studies stating that there is reduced electricity costs due to the reflectiveness of the surface.
This is a great question, because unlike tiles, can be extremely cold to touch, polished concrete does not feel cold. Due to the size of the slab it is a good insulator and therefore will feel much warmer than tiles to touch.
Part of our grouting procedure can actually fill in small cracks, and if you choose a full polish the procedure actually hardens the top surface by up to 10 times its natural strength. If cracks do appear we can generally repair them. However it is concrete and that is the one thing we can never guarantee that is it won’t crack.
Yes, often polishing jobs are done on existing concrete which is made from the most common mineral on earth – limestone. Concrete is a very small contributor to greenhouse gases, and will out perform timber, steel, carpet and tiles.
