# Calculate the need for leveling compound per square meter

Before a floor is provided with a new surface, it must first be straightened and adjusted in height in most cases. Here, the need for leveling compound or leveling mass plays a major role.

### What you often expect under old flooring

Floors that are torn out during renovation often have uneven surfaces. Often the underlying screed gets damaged, which gets stuck on the old floor covering. Unfortunately, it is not so easy that you can now simply submit a new rubber. Flexible floor coverings such as carpet adapt to uneven surfaces, at least for a while. In the long term, the floor coverings can be damaged. Tiles can not be laid on uneven surfaces at all. Therefore, you must straighten the ground with balancing mass. Depending on the existing substrate, a lot of material may be needed.

### What the need for leveling compound depends

There are several things on which the need for leveling compound depends, such as the number and depth of damage to the old floor and, of course, the layer thickness with which the leveling compound or leveling compound must be applied. The more uneven the soil is, the more material is needed. Of course, this can also drive up the costs very quickly. One speaks per millimeter of strength and per square meter of costs between approximately 3.00 and 6.00 euro. If you want to remove coarser bumps, you should consider screed as an alternative, as the costs are much lower here. However, you also have to expect a greater amount of time for drying when processing it. Balancing compound offers you the following advantages:

• Leveling compound works well on surface heating systems.
• The material offers good flow properties.
• The leveling compound can be walked on after just a few hours, and after half a day a new floor covering can already be laid.

### Example of a calculation of the required quantity

Here's an example: A room with about 20 square meters of area should be provided with leveling compound. It requires a layer thickness of 3 millimeters, resulting in a total amount of 102 kilograms. Divide the whole thing by 20, you come to a total of 5.1 kilograms. The consumption per millimeter layer thickness should be taken from the manufacturer's instructions for your leveling compound as the value varies.
