We specialise in providing quality Darwin concrete floor grinding, polishing and finishing. You can count on us to deliver outstanding results for your home, office, factory floor or any other premises.

Polished Concrete

Floor Grinding NT are also HTC Superfloor(TM) accredited. We provide a complete concept for polishing concrete. A premium polished concrete is a mechanically refined concrete floor. This method involves removing the surface paste and exposing the underlying stronger concrete. The extensiveness of the work involved depends on the exposed aggregate, the depth of grinding required and the kind of concrete that has been worked and finished by a concrete contractor.


To achieve a polished appearance, we begin with a rough grind and gradually grind up to a fine grade. Using quality diamond segments and special resin bond tools on the floor surface, we can transform a concrete floor to a beautiful surface. Between concrete grinding stages, concrete hardeners (densifiers) are used to increase durability and strengthen the concrete floor.


Once the finished appearance is achieved, a special concrete penetrating sealer is applied. It is important to keep in mind that the sealer is not a coating but simply a stain resistant sealer, which penetrates beneath the surface to enable cleaning and to stop a majority of contaminants from staining the concrete floor. The end result of this premium polished method will be a very smooth and durable surface, perfect both functionally and aesthetically.


A finished polished concrete floor will enhance the natural beauty of your home and also create a low-maintenance, durable floor.

Polished Concrete With A Topical Sealer

This is a concrete floor surface that has been mechanically ground back using diamond tools. Depending on the concrete floor surface presentation, usually two our more grinding process stages can be performed and then a topical sealer applied. Topical sealers refer to a type of coating which covers the surface of the concrete, providing a protective barrier. It is a layer of thin film sitting on top of the concrete. Both solvent and water-based sealers available.

Seamless Epoxy Floors

Our Darwin concrete floor experts can apply decorative epoxy coatings, acrylic flake systems and stone grip (river sand) systems. Epoxy coatings can incorporate acrylic flakes, with an extensive range of base colours and patterns to choose from.


Another system that can be used with epoxy is the stone grip system. This comprises a combination of micro flakes and river sand, which is primarily used where a non-slip floor is required. It also displays a beautiful colourful texture.

Concrete Floor Grinding Surfaces

Grinding all old & new concrete floors Floor preparation/stripping old finishes involve grinding and preparing the concrete floor. Removal of floor substrates, ceramic tile & vinyl adhesives, paint, glues, epoxy, self-levelling epoxy, putty and much more.

Grinding and Levelling

This process involves preparing the surface by grinding and removing any irregular spots or humps in the floor surface.

We Use Quality Concrete Finishes

These include:


  • Topical coatings & impregnating sealers
  • Water based sealers
  • Seamless epoxy
  • Densifiers
  • Non-slip coatings
Floor Grinding Machines Used

Swedish company HTC are the leading manufacturer and supplier of floor grinding equipment. They have the largest range of floor grinding machines for floor preparation and floor polishing.


We use an extensive variety of HTC Machines. This includes HTC floor grinders, HTC edge grinders and HTC dust extractors. The machines we use range from heavy duty three-phase and single-phase grinding machines, through to handheld grinders.


The floor grinding units we use are among the latest and most advanced anywhere in the world. All our grinding machines use a dry grinding method. They are equipped with a heavy duty three-phase and single-phase dust extraction system to minimise dust within the surrounding areas. The systems we use are safer, cleaner and more environmentally efficient than other options.

Floor Polishing

Maintenance For Sealed & Epoxy Coated Floors

  1. Use mats
    Shoes carry sand, grit and small stones which will abrade the floor surface in the same way sandpaper does. Place mats at entrances and, where possible, place a mat on the inside, as well as outside. Use runners and rugs in high-traffic areas.
  2. Direct light
    Like any quality furnishing or floor covering at your home or business, direct light (sunlight and artificial light) will cause discolouring over time. To avoid fading and discolouring, filter direct light with curtains or blinds. As floors that have been exposed to light will change colour over time, remember that areas of floor covered with rugs will retain their original colour. Therefore, once rugs are removed, or their position changed, variations in colour will become invisible.
  3. Maintenance plan
    The most important thing you can do to keep your floor looking like new is to establish a regular cleaning/maintenance program. How regularly you need to maintain/clean the floor is totally dependent on the environment the floor is in. Factors such as the level of traffic, the degree of grit carried onto the floor, pets and children, as well as the condition of the immediate outside area etc., all have significant influence on the wear of the floor. In case of spillages, it is vital that it is wiped up immediately.
  4. Daily/weekly
    Use an anti-static dust mop to collect all dust and dirt. It is important to note that although some people use a vacuum cleaner, we generally would recommend against this. This is due to the fact that often the brushes on the vacuum head wear thin and the floor is scratched by the metal.
  5. Weekly/monthly
    Wash the floor and avoid harsh detergents. We recommend a neutral floor cleaner (FeastWatson floor clean, Enviropro Squeaky Clean, Rockstar sealing neutral clean), which has been specially formulated for the maintenance of floor coatings. It is also important to use a cleaner suitable for terrazzo, ceramic, vinyl and lino floors. Apply with a sponge mop and wring out the mop in clean warm water. Wipe off excess, leaving a damp finish on the timber surface. Use only cold or lukewarm water, as hot water can damage the coating surface. Never flood coat a floor with water as, in extreme cases, it causes coating separation from timber swelling at board gaps.
  6. Recoating
    It is advisable to apply a maintenance coat before the surface has been excessively worn. This will prevent the need for expensive resanding. Exactly when this maintenance coat will be required is entirely down to wear and care. Obviously, the greater the traffic the sooner the need for a recoat.

Maintenance For Natural Polished Concrete Floors

Every floor premises with natural polished concrete will generally have a maintenance cleaning procedure. The amount of traffic on the floor will determine how often cleaning and maintenance should be scheduled.

Please note that you should never apply sealers or waxes on the floors, as these floors are not coated with any topical sealers. Entry floor mats, such as long pile coir mats and short pile mats, inside entrances are recommended.

All mats must be shaken out and cleaned on a regular basis. This is because grit and dirt (i.e. sand, paver and concrete particles) are highly abrasives and can act like sandpaper. Depending on the type of surface, abrasive particles on polished concrete can deteriorate the shine. On topical coatings, they can also scratch the surface and reduce the gloss level.



Spillages/Stains:



Any liquid contaminants should be cleaned up immediately. As most polished floors have a stain-resistant sealer or coating applied, this will temporarily stop the absorption rate of such contaminants from reacting with the substrate and surface. Acidic liquid contaminants, such as orange juice, can react with the surface. The stronger the acidity levels, the faster the reaction. Spillages of red wine, oil or coffee should also be cleaned up in a timely manner, as some of these can penetrate, causing discolouration and spots in the concrete. To make sure your floor is not left etched, discoloured or scarred, all liquids should be cleaned in a timely manner.



As General Guideline In Cleaning



  1. Dust mop floors daily using a micro dust mop, an electrostatic dust mop or a soft-bristled broom. Micro dust mops generally tend to collect dust more efficiently. Alternatively, a vacuum cleaner with a soft bristled head can be used.
  2. Damp mop with a neutral ph cleaner (i.e a FeastWatson floor cleaner, a TwisterTM cleaner, or a specific neutral cleaner solution). For low traffic areas, mopping once a week is advisable. For a premises with heavy traffic, daily mopping is recommended. If you find that the water is dirty, clean the water and repeat the damp mop process to ensure the surface is clean.
  3. Allow to dry.
  4. To avoid losing the surface floor shine of your polished floor, don't use harsh floor cleaners and aggressive cleaning pads.
