As with any kind of equipment, users often have questions about how to use floor sanders effectively. Therefore, in this blog post, the experts here at Concept Flooring Technology will answer some frequently asked questions about concrete floor sanders.

What is a concrete floor sander?

A concrete floor sanders is a heavy-duty machine designed to grind and polish the surface of concrete floors. Most sanders use a motor to power a rotating disc containing abrasive particles, which wears down the floor’s surface and thus removes roughness and unevenness.

Many are also compatible with both large and small dust extractor systems that can remove any dust and debris created during the sanding process.

How do they work?

Sanders use rotating discs with abrasive pads to grind down the surface of a concrete floor. These discs come in varying levels of coarseness, allowing the user to gradually grind the surface of the concrete down to the desired level of smoothness.

Most applications will call for a coarse grit sanding disc to be used first, which will remove any bumps or rough areas on the surface of the concrete. Once these areas have been smoothed out, you’ll likely need to switch to a finer grit sanding disc to further refine the surface of the concrete.

You may then choose to polish your concrete floor, which will involve using a grinder polisher fitted with a series of even finer abrasive pads until the desired level of shine is achieved.

What types of concrete floor sanders are available?

Here at Concept Flooring Technology, we offer both the Schwamborn STR701 Sander and the Eibenstock ELS225 Long Reach Pole Sander.

The STR701 sander is compatible with a range of silicon carbide sanding discs, copper tungsten discs and diamond grinding blades in various grades of coarseness. This makes it a very versatile option that can be used across a range of applications, including completing remedial work, keying an existing coating, or removing thin materials.

It is especially well-suited to removing laitence from a screed, which is essential for ensuring that you achieve a smooth and durable surface for subsequent work, such as tiling, painting, or sealing.

The ELS225 pole sander, on the other hand, is best for sanding elevated and hard-to-reach areas such as walls and ceilings. This lightweight handheld machine seamlessly rotates its 100° tilt angled head, making fiddly tasks much simpler, and is compatible with a range of sanding discs. It also comes with its own compact dust extraction unit, which results in a relatively mess-free experience.

Are floor sanders expensive?

Buying a floor sander outright can be expensive, and often feels like an unworthy investment if you are only likely to use it for one job. However, floor sander hire is very cost-effective and means that you won’t end up with unwanted equipment at the end of your project. You will have access to high-quality, fully-maintained plant hire equipment at fantastic rental prices.

When it comes to your business, appearances really do matter. A well-kept commercial property conveys care, attention, pride and professionalism; every aspect, from the front door to the lighting plays a part in your reputation. Among the most important of these elements is the flooring.

Commercial flooring must be properly maintained to keep it looking its best. This is especially true of concrete flooring, which has experienced a surge in popularity of late. In order to properly polish concrete flooring, a high-quality commercial floor polisher is essential. If you’re looking to hire one of these machines, but would like a little insight as to its correct operation, read on.


Firstly, it is important to prepare the area you wish to polish. This includes clearing away any debris, dirt or dust. It is worth noting that failing to properly prepare an area for polishing can seriously impact the end result. For example, debris such as bolts can damage the grinder heads and create holes in the dust extractor hoses and filters, which will undoubtedly affect the efficacy of the machine.

Dust Extraction

In addition to the grinder polisher itself, it is important to use an effective dust extraction method. Machines such as the HTC DURATIQ RX8 Grinder Polisher are designed to be connected to a purpose-built dust extraction machine such as the HTC 80D (also known as the Husqvarna 80iD). All of the machines available to hire from us here at Concept Flooring Technology are set up to be used dry, as this eliminates the possibility of creating a slurry when grinding.

Speed Settings

Next, you’ll need to consider the speed at which you wish to polish. When choosing a commercial floor polishers, you will need to ensure that the machine boasts variable speed settings in order to achieve the desired finish. Single speed machines are only suitable for preparation grinds, so it’s important to avoid these for polishing applications.

In terms of setting the appropriate speed, a lower speed may be needed for removing heavy scuffs, while a higher one may be needed for final polishing. Make sure to adjust the speed according to the nature of the task and the condition of the floor.

Polishing Technique

Once you’ve chosen a suitable floor polishing machine and set the appropriate speed, you can begin polishing the floor. Begin by working in small sections, moving the polisher slowly and evenly across the surface. Be sure to keep the machine moving, as staying in one spot for too long can cause an uneven finish on your concrete flooring.

Consult The Operating Manual

It goes without saying that the use of large cleaning machinery requires focus and proper preparation. To familiarise yourself with any piece of equipment, it is highly recommended that individuals examine the relevant operating manual before attempting use.
