What is the process involved in polishing concrete?

There are different processes for polished concrete on a new build compared to a renovation. There are also different processes for coatings and if the area is indoors or outdoors. To help you with more detailed information we have PDF files you can download on the system that applies to you right here

How far do you travel?

Spec Floors are based in Barnawartha on the border of NSW and Vic. We are happy to travel to most areas of Vic and NSW. We have a service area map where you can check which service area you are in.

What curing agents are OK in our mix

A shrinkage reducer called Eclipse used in a 5l per m ratio is compatible with our products and so is Sika Film. Sika Film is a curing agent which is topically sprayed on after the slab is poured. 

Can you polish old concrete?

In most circumstances the answer is yes. While the colour and aggregate distribution may be an unknown quantity until the grinding takes place - in most situations the floors can look amazing. An on-site inspection is always required to existing buildings to ensure there are no other issues that may hinder us being able to give you a high quality floor. We can discuss possible outcomes after assessing the quality of your concrete and help you choose the right polishing system for you. We have also developed a tips for renovators fact sheet to assist additional points of consideration when working with an existing concrete floor. There are also process documents on our downloads page for existing homes to help you select the system that is right for you.



How much does it cost?

Like anything - the price can vary enormously. It depends on the system you choose, the preparation work required, the job size, access, the environment and location and the finishing level selected. We do offer 'no obligation free quotes' so please fill in the form and email plans (with measurements and areas clearly marked) or ask for an onsite inspection via our get a quote page.

As our quotes factor in time and resource allocation on a job some things that will increase price can include mutiple levels, seperated areas, specialty crane lifts, additional hand work on existing builds, drainage areas, steps or face edges or a need to have multiple staff on site for OH&S.

Why do we have to wait 3 weeks after slab pour before grinding?

The simple answer is to ensure our clients get the best possible floor. See our slab recommendations or the specific system process you would like for more information. Our fact sheets are all available on our links and downloads page.

What do you need clients to provide onsite?

We have our own generators and bring them along with all the tooling, products and machines to complete the work. All we require is clear access for our truck, normal power connection, water and toilet facilities and a skip (or other agreed arrangement) for the disposal of the dust bags and waste.

Can I have polished concrete in my bathroom and shower?

Technically yes, and many people do. Depending on the system you are wanting and the finishing options you would like there may be some considerations for slip, consistency of exposure or ensuring council approval, however with the co-operation of your builder and forward planning, generally we can achieve the outcome you are after. Keep in mind polished concrete should not come into contact with acidic or alkaline agents so consideration may need to be given to what products are used in these areas such as soaps and shampoos etc.

Do you pour the concrete as well?

No. We specialise in the finished product rather than pouring. Working exclusively with concrete has allowed us to come up with some recommendations for new slabs to help our customers achieve the best results. We have found, through our experience, some concrete mixes do polish better than others and we always ask our clients to confirm where they intend sourcing their supply from prior to locking it in - just to ensure they are getting the quality they need for their polished floors.

Is polished concrete slippery?

Slip is very hard to describe and interpret, what someone may think is fine another person may find very slippery. Generally speaking the higher the gloss level and the flatter the surface the slipperier a floor will be especially when wet. In our opinion in dry conditions polished concrete performs just as well, if not better, than tiles of a similar gloss level. If you are concerned about slip in an area exposed to water (uncovered outdoor/pool area/ shower) either reducing the finishing level for polished concrete or adding grit to a coating system can assist in achieving better grip. The grind, etch and seal system has been designed specifically for areas requiring considerable grip and is suitable for outdoor areas exposed to weather.
