What is Aerated Concrete?

Before we go deeper into cutting aerated concrete, let's first take a look at what aerated concrete actually is. Aerated concrete, also known as aerated concrete or Ytong, is a lightweight building material consisting mainly of sand, lime, cement and water. It is known for its excellent insulating properties and is often used for walls and partitions in both residential and commercial buildings.

The Necessary Tools

Before you start cutting aerated concrete, make sure you have the right tools. Here are the essential tools you will need:

  1. Aerated concrete saw : A special saw designed to deal with aerated concrete. This saw has diamond blade teeth and ensures precise cuts without damaging the material.

  2. Safety equipment : Safety is paramount on every job. Be sure to wear protective gear such as goggles, dust mask and hearing protection to protect yourself from dust and possible flying particles.

  3. Measuring Tools : A tape measure and a pencil are essential to accurately mark the cuts before you start cutting.

  4. Spirit Level : A spirit level will help you make sure your cuts are perfectly straight.

Sawing Aerated Concrete - Step by Step

Now that you have the necessary tools, we can begin the actual sawing process. Follow these steps to successfully perform aerated concrete cutting:

  1. Preparation : Make sure that the aerated concrete is firmly fixed before you start cutting. If necessary, place it on a stable surface and make sure there is enough space to work safely.

  2. Marking : Carefully measure and mark the cuts on the aerated concrete surface using a tape measure and a pencil. Make sure your markings are clear and accurate.

  3. Safety First : Put on your safety equipment before starting the saw. Protect your eyes, lungs and hearing from possible hazards during the sawing process.

  4. Sawing : Turn on the aerated concrete saw and start sawing along the marked lines. Hold the saw firmly and apply even pressure while cutting. Let the saw do the work and don't force it.

  5. Check the Depth : Check regularly that the cutting depth is correct, so that you do not cut too deep than necessary. This prevents damage to the underlying structure.

  6. Cleaning : After completing the cut, thoroughly clean the work area from dust and debris. A clean environment promotes a safe working environment and accuracy in future cuts.


Cutting aerated concrete can be a challenging job, but with the right tools and the right approach it is doable. Follow the steps in this guide carefully and always ensure your safety when doing jobs. We hope this detailed guide has helped you and wish you the best of luck with your project!
