Cutting stone can be a difficult task, especially when it comes to rock types such as concrete blocks , granite or natural stone . However, the formation of dust can not only be a health hazard, but also adversely affect the entire project.

Dust can build up on the surface and result in a ragged cut and an uneven cut. In this guide, we'll show you how to cut stone without creating dust or minimizing dust creation to the maximum.

1. Cutting stones without dust - what methods are there?

1.1 Method 1 - Wet cutting is the best method to prevent 99% dust.

The most effective way to cut a stone without dust is wet cutting. Water is sprayed onto the cut to bind dust and ensure a clean cut.

This method is particularly suitable for natural stones such as marble or granite, but also for concrete and tiles . Wet cutting is integrated into a cutting table. When cutting stones with the angle grinder, a spray nozzle can be used to spray directly on the cutting edge or in the surrounding area.

1.2 Method 2 - A suction device sucks up the dust when cutting stones directly at the cutting point.

Another effective way to bind dust while cutting stones is to use an extraction hood . This device can only be used on a 125 mm or 230 mm angle grinder in conjunction with a diamond cutting disc.

The extraction hood extracts the dust directly at the interface and prevents it from spreading to the surrounding area. Another beneficial effect is the avoidance of dust particles being deposited on the interface.

1.2 Method 3 - Dust binding agents the emergency solution

Another way to prevent dust when cutting stone is to use dust binders. These binders are applied to the cut and bind the dust before it can become airborne. This method is particularly suitable for indoor use.

2. Can I use any dust-free stone cutting method for any type of stone?

No, not every method is suitable for every rock type. For example, wet cutting is better suited for natural stones such as marble or granite, while the use of dust binders is more suitable for indoor use.

2.1 Health Benefits

Cutting rocks without dust offers numerous health benefits. Avoiding dust reduces the risk of respiratory diseases and allergies. In addition, the development of eye irritation and skin rashes can be avoided.

2.2 Can you cut stones in the residential area?

It is required by law to avoid high levels of dust exposure . This also applies to the outside area. If this regulation is not observed when cutting stones and neighbors are bothered by the dust produced, a fine can also be imposed.

  • Announcement is made
  • call the regulatory office
  • Record evidence of dust exposure
  • note times

2.2 How do I ensure a clean working environment when cutting stones?

By avoiding dust, a clean working environment can be ensured. This means that the dust does not settle on the surface and a clean cut is achieved. This can make the whole project easier and improve the quality of the cut edge. This advantage should not be underestimated, especially with high-quality stones such as marble and granite.

Our experience: The error rate of unclean cuts can be proven to be minimized by preventing dust!

2.3 Is avoiding dust when cutting stones more expensive?

There is no definite answer as to whether avoiding dust when cutting stone is more expensive or not.

For example, using a cutting table with a wet cutting function can be slightly more expensive. On the other hand, using a dust extractor can reduce overall costs as it can extend the life of the cutting tool. Extraction hoods are available from us for as little as €30.

2.4 Important - How can I also ensure that I do not inhale any dust particles when cutting stones?

The best additional protection against dust particles when cutting stones is to use a respirator. There are different types of respirators. We are of the opinion that an FFP 2 mask is already sufficient.

3. For which other areas of application can these tips be implemented?

Of course, these tips can be applied to many other material groups and not just stones. For example:

  • Cutting screed without dust
  • Flex without dust
  • Cut wall without dust

1. Are these methods designed to cut concrete slabs without dust?

Yes, of course. The wet cut, the suction hood and the dust binding agent can also be used for dust-free cutting of concrete slabs. Depending on the thickness of the concrete slab, the angle grinder method may not be sufficient due to the limited depth of cut.

2. How to cut masonry without dust?

If the masonry is indoors, using an extraction hood for the angle grinder (125 mm and 230 mm possible) is the only reasonable method.

3. Can you cut paving stones without creating dust?

The best way to cut cobblestones dust-free is to use a wet saw. This binds the dust directly when cutting and carries it away with the water. If you are cutting paving stones in a residential area, we advise you to use a suction hood for the angle grinder.

Conclusion - Stones can be cut dust-free without much additional effort

Avoiding dust when cutting stones can not only protect health but is also required by law . There are various methods to avoid dust, such as wet cutting, the use of dust binders and vacuum devices .

It is important to choose the right method for the specific stone, taking into account cost and effectiveness. With the right precautions and tools, stone cutting can be done easily and safely without dust.
