How Much Does Concrete Grinding Cost In the Gold Coast

 The cost of having your concrete floor polished or ground can vary considerably depending on the situation and the requirements of the job. A very simple job in a small space may be a lot more expensive per square foot than a similar job on a large area simply because it is so much easier to use a machine or a larger machine in a large area. Very small areas with tight corners and many doorways or other obstacles mean that a much smaller machine needs to be used which not only takes longer but need a very experienced operator to produce a high quality job.

A basic floor grinding can cost from $10 per m2 where it just requires grinding and honing with a clear coating that exposes the stone on a floor that is is good condition.

If the floor has tile glue, vinyl or carpet glue, etc. it can cost $18 perm2 and if there are existing tiles or floor coverings it can cost around $25 per m2.

The finish that is required also affects the total price, do you want what is known as a "Cream Finish" which is where the surface or troweled concrete finish is buffed into a glass smooth finish with a penetrating type of sealer. This type of finish is often used in garages or commercial floors where they require a very strong long lasting floor. The usual cost of this type of finish is about $70 per m2.

To get what is called a "Salt n Pepper" finish where the concrete is cut lightly to expose the fine sand and stones to give a more decorative finish then sealed with a penetrating sealer, this finish is suitable for most areas including decks and hallways, living areas and commercial areas. This type of grinding costs about $80 per sq. m2.

Full stone Exposure Grind and polishing where the concrete is cut down to expose the full or maximum amount of stone, then sealed and polished where a decorative effect is required This is often done in the home or areas such as restaurants. This usually costs about $100n per sq.m2

Other factors that can influence the price of a particular job are whether the job is on a new or existing cement. It can cost 30% to 50% more for working on older concrete especially if there are cracks or other damage that first needs to be repaired.

There are a number of special effects that can be achieved and these can range in price from a few extra dollars per sq m2 to $50 or more depending on how elaborate your require your floor to be.

Sometimes an existing floor will require some extensive repairs, especially those in older homes as they were never meant to be ground and polished, they were poured as a foundation. These types of floors can be successfully ground, but it may be prudent to consider having the floor skimmed with a new coat of concrete that will be ground and polished. Your contractor can advise you about this. One of the advantages of doing this is you can choose the aggregates (different stones and sands) you use and also the color of the cement so you can make a floor that is truly unique to your building. This option can be very cost effective as the concrete grinding job is simpler and therefore less expensive and the finish is very predictable
