How Much Does Polished Concrete Flooring Cost?
If you’re wanting an exact price or a general price range on how much polished concrete floors cost, you won’t find it here. That’s because the price of polishing concrete is very variable from project to project.
We can certainly give you an estimate on how much it’d cost you to install polished concrete flooring in your home or business, you just need to contact us directly. To get an accurate estimate, it’s best for you to send us photos or organise a site visit.
If the area is approximately 60m2 or more, then you’ll be given a per square metre rate. If it’s less than 60m2, you’ll generally be priced a minimum day rate.
Curious to know the factors that affect the cost of installing polished concrete flooring? Let us break it down for you.
The Area Being Polished
It’s probably no surprise to find out that the size and dimensions of the space being polished has a significant effect on the price, but what may surprise you is that a smaller space isn’t necessarily cheaper. Concrete grinding and polishing can be done by a machine or by hand – machine grinding gets great results in a lot less time, so if most of your floor can be polished by a machine then you can expect to save some money on labour costs. So, what areas can’t be grinded and polished using a machine?
Perimeters
The machines are big, and the last thing we want to do is damage your wall, so hand grinding is done on any flooring within 10mm of a wall. Although there may be more concrete to polish in one large room as opposed to many smaller rooms, the large room would likely have less labour costs as there’s a smaller total area close to a wall. This is why we usually recommend that new builds get their concrete grinding and polishing done before the inner walls go up!
Confined Spaces
Really small areas, like shower bases, cannot fit a polishing machine at all as the machines are fairly large. This means very confined spaces are generally 100% done by hand grinding. It can take one full day to do one shower base, which is very labour intensive and therefore very expensive.
Stairs and Ledges
Stairs and ledges are too narrow to balance the machine safely, so they need to be done entirely by hand grinding and polishing. Like with the confined spaces, this is very labour intensive, and the cost will reflect that.
Vertical Surfaces
Grinding and polishing machines were made for floors, so any vertical surfaces like walls or the risers on stairs need to be done entirely by hand.
The Appearance You Want
Not all polished concrete looks the same, these different looks are achieved through different levels of aggregate exposure and gloss. These things will affect the price as they will dictate the amount of time and product needed to get your floor to match your preferred look.
- Aggregate Exposure: The aggregate is made up of the stones in the concrete. Getting really decorative polished concrete requires exposing a lot of the aggregate, which requires cutting deeper into the concrete slab. The deeper the grind needs to be to expose the aggregate, the more expensive your bill will be in order to pay for the labour costs of additional grinding.
- Gloss Level:Put simply, the higher the gloss level, the higher the price. To get a really glossy floor, we need to do more passes with the polish er which takes more time and uses more resin. The higher price is to cover the costs of the labour of the polisher and the cost of the resin.
The Age of the Concrete
If you want to polish an old or existing slab, then there will be a cost associated with preparing it for grinding and polishing. Before any polishing can be done, we would need to remove all traces of previous coverings such as paints, sealers, glues, mortar, tacks, and nails. Once that’s done, we’d then need to repair any cracks or holes, which will definitely be there if you’ve had carpet covering the concrete.
New slabs are generally cheaper to grind and polish as we can get straight to work. Unless there was a major problem in the pour, we wouldn’t need to spend any time in repairing the slab to prep it for grinding and polishing.
Cost Saving Overtime
Although concrete grinding and polishing can have a large upfront cost, especially if you’re using an experienced and trustworthy company for the job, it can actually work out to be cheaper over time. The reasons for this are:
Long-Lasting Flooring
As with anything, paying for your flooring once is going to cost you less than paying for it multiple times over the span of years. A genuine mechanical polish has had hardening solutions worked into the concrete, filling microscopic holes, and making the concrete denser. After further processes sealer is used, which seeps down approximately 20mm into the concrete. This type of finish lasts decades as long as it’s treated and maintained correctly, the same cannot be said for other types of flooring.
Maintenance
Polished concrete is easy and affordable to maintain, making it a smart long-term flooring choice. To keep it looking its best, simply:
- sweep or vacuum regularly using a brush setting
- mop occasionally
- clean up spills as they happen
- use a pH-balanced cleaner to protect the finish
Compared to timber, carpet, and tiles, polished concrete is far less demanding. Timber needs re-sanding and resealing, carpet requires regular shampooing and replacement, and tiles need ongoing grout cleaning and sealing. With polished concrete, there are no grout lines to trap dirt, helping keep maintenance simple and costs down.
Health
Polished concrete is the healthiest flooring choice you can make, as it doesn’t trap dirt, allergens, mold, or oils, nor does it contain harmful volatile organic compounds (VOC). The same cannot be said of other flooring options.
