Polyurethane is a plastic material, which exists in various forms. It can be either rigid or flexible, and is the material of choice for a broad range of products such as: insulation, mattresses, car parts, coatings, adhesives, tyres etc.
Polyurethane floors and floor coatings are a layer of polyurethane that is applied to a flooring surface in order to protect it from various elements. There is a difference between a floor and a floor coating. Polyurethane floors can normally be installed to 6-8 mm thick where polyurethane floor coatings can achieve up to 1-2 mm in total thickness. Both polyurethane floors and floor coatings protect your concrete and steel from corrosion and abrasion.
Various water and oil based polyurethanes products have been widely used to protect and beautify concrete floors. Some products are low in odour while others offer harder finish. Polyurethane come as: water based (low or no odour), solvent based, moisture cured, two packs, clear, coloured and high in film build. All polyurethane coating we use are UV stable so they will not turn yellow over time. Polyurethanes can be applied as clear coatings or in various colours, in high gloss, semi gloss, matt or as anti slip finish. So to make it clear there are clear and coloured polyurethanes which are completely different. Clear polyurethanes are usually used polishing concrete look is desired.
How polyurethane floor coatings are installed?
Check your concrete slab for evidence of any underlying moisture problems and run a number of surface moisture tests. If all test result are acceptable then your job can go ahead using a standard preparation and application procedure which involves:
1. Step 1 – Concrete Grind and polishing up to 120 grit metal bond including any repairs.
2. Step 2 – 3 coat product application of your choice. Light buffing and vacuuming between all coats is strongly advised, using 120 and later 180 grit mesh. Curing time between coats will depend on concrete porosity, materials you use, room temperature and air flow. But as a rule of thumb allow 1 day between each coat.
You can decorate your concrete before applying polyurethane by staining your floor, applying various decorative screeds etc, which will increase the overall cost of your flooring project.

We only use high quality UV stable polyurethanes.
The lifespan of your floor coating depends on many factors, is the surface inside or outside, how much traffic and abuse it will get, how clean is it going to be kept, is it going to be exposed to chemicals and/or fats? All of above would determine whether your floor would last you for a month or for decades.
As a rule of thumb, look after your floor and it will service you for a long time.
On average the cost to grind, polish and seal your concrete floor using polyurethane would be anywhere between $85 – $115 p/m2 + gst, for decorative options such as stain and patterns you would be looking in excess of $160 p/m2
If you are after a clear gloss finish we apply 3 coats of either single or two pack polyurethane. For coloured applications we would need to apply 1 coat of epoxy base first and then 2 coats of 2 pack polyurethane.
It will depend on your job size but it may take us anywhere from 3 days and longer.
Noise – yes, Dust – No
Our floor grinders are quite smooth and not that noisy at all but our hand grinders and dust extraction equipment produces a bit of noise, but there will be no airborne dust.
Unfortunately we are no longer accepting credit cards. EFT is our preferred payment method.
Our regular turnaround is around 2-3 weeks.
Epoxies and coloured polyurethanes finishes look and feel the same. But there are few very distinct differences. Epoxies chalk under UV light when used as top coats when UV stable polyurethanes will not discolour or chalk under UV light. They are also more tolerant to tension and more flexible to withstand concrete movement.
