Frequently Asked Questions

Polished Concrete

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.

At Envirocoat we 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.

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.

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.

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.

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.

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.

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.

There has been studies stating that there is reduced electricity costs due to the reflectiveness of the surface.

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.

No, Envirocoat specialises 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

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.

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.

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.

Envirocoat uses a sealer on all our finishes which prevents staining. However we do recommend that spills are cleaned up quickly.

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.

Epoxy Flooring

A flake system floor gives a texture feel to it and is normally no more slippery than regular concrete when wet. If you have a concern about slippage, we can add a slip resistant additive to the topcoats which will make the floor more skid resistant.

Yes. Outdoor patios, paths and common areas

Depending on the time of year and temperature, you can normally walk on surface within 24 hours and drive on surface within 7 days.

Most installations can be completed within 1 to 3 days depending on the coating system used.

Price will vary depending on square meters, amount of crack and concrete repair, and if there is an existing coating to remove. A typical two car garage will range from $1,800.00 to $2,500.00.

Our process utilizes a dustless grinding system and leaves very little mess.

For a light cleaning just use a broom, dust mop, or leaf blower. Simple water applied with a mop works great for a deeper cleaning.

You’ll want to stay away from soaps because these leave a film, which, when wet, become very slippery.

A major advantage of the flake system is that it does a good job hiding minor imperfections in the concrete. Since each flake color pattern incorporates many colors; you can select one that will go best with your décor and/or siding and window colors.

Yes, an epoxy floor is very strong and durable, but it can still be damaged mechanically or if the substrate (concrete underneath) were to be damaged. For example, if a heavy object like a sledge hammer were to be dropped on it or if you were to drag a heavy table with steel legs across it. An epoxy floor can be scratched just like regular concrete can be scratched. An epoxy floor will be very durable and last for years looking beautiful with reasonable care.

All residential applications have a two year limited warranty against peeling (delamination), and material defects.

Cracks and other repairs which give way due to the shifting of the substrate below are not warranted.

We will repair the cracks and pop outs in your floor before we install the epoxy coating.

A professionally installed epoxy floor by a certified installer will give you a high quality and beautiful floor which will last. The most important part of any concrete surface application is surface preparation. We use top diamond grinding equipment with an environmentally safe vacuum system to collect hazardous concrete dust and contaminants. We also use only commercial/industrial grade epoxy products which are guaranteed and proven over thousands of square meters of concrete.
