Calculating the leveling compound and leveling compound is not that difficult if you know how to do it
Our experience: With a self-levelling compound, the new floor becomes even and beautiful with little effort.
But how much leveling compound do you actually need?
All do-it-yourselfers are faced with this question when it comes to leveling, because the required amount depends on the unevenness of the subsurface.
In this article you will learn how to calculate the right amount of self-leveling compound for your floor.
1. layer thickness
1.1 Determination of the layer thickness
To determine the required layer thickness of the leveling compound, divide the total area into different zones of one square meter each.
Now place a spirit level over the bumps and use a meter stick or ruler to measure the height of the indentations under the spirit level.
Note the value of the highest depression. Repeat this for each drawn zone.
Example: The room is 10 square meters.
|Zone||Height of indentation (mm)|
1.3 Measurement of wells
Now add up all values and divide by the number of zones:
5 + 3 + 5 + 7 + 4 + 4 + 2 + 6 + 5 + 3 = 44 : 10 = 4.4.
Divide this value by two:
Result: 4.4 / 2 = 2.2.
So on average you need 2.2 mm of leveling compound to fill in all the indentations.
1.4 Additional Buffer
Add two millimeters to have an extra buffer. As a result, you should plan for a layer thickness of 4.2 mm.
2. Leveling compound
2.1 Calculation of the required quantity
To get from the layer thickness to the required amount of leveling compound, proceed as follows:
Check the label of your product to find out how much leveling compound is required (in kilograms) per millimeter of layer thickness.
In most cases, the consumption is 1.5 kg per square meter and millimeter layer thickness.
Now multiply this value by the layer thickness and the number of square meters of the room.
2.1 Consumption of leveling compound
1.5 x 4.2 x 10 = 63.
So you need a total of 63 kg of self-levelling compound.
2.2 Amount of leveling compound
After you have calculated the amount of leveling compound you need, you can buy and use it accordingly.
Our tip: Make sure to buy in bulk and get a bulk discount.
3. Tips and Tricks
3.1 Preparation of the substrate
Before you apply the self-levelling compound, it is important to clean the subfloor thoroughly.
Remove dust, dirt and old glue residue to ensure optimal adhesion of the mass.
3.2 Application of the leveling compound
- Mix the leveling compound according to the manufacturer's instructions and pour it evenly onto the floor.
- Spread the compound out with a smoothing spatula or notched trowel.
- Then let the mass flow and level independently.
3.3 Drying time leveling compound
The drying time of the leveling compound varies depending on the product and layer thickness. Check the packaging for the recommended drying time and do not walk on the floor until this has expired.
4. The biggest advantages of leveling compound
4.1 Flatness and optics
An even floor not only looks appealing, but also makes it easier to lay tiles, laminate or parquet.
4.2 Avoiding Problems
Unevenness in the floor can lead to problems with the stability and durability of the new surface. By leveling with self-leveling compound, you prevent such problems and ensure a long life for your floor.
5. Conclusion - Calculating the required leveling and balancing masses is comparatively easy
Calculating the required amount of self-levelling compound is an important prerequisite for an even and durable floor. With the right calculations, preparation and application, you can achieve an optimal result.
6. The most frequently asked questions about the calculation of leveling and balancing weights
1. Can I also use the self-levelling compound for underfloor heating?
Yes, in most cases the leveling compound is suitable for underfloor heating. However, pay attention to the manufacturer's information to ensure that the product is suitable for your specific application.
2. How long is the processing time of the self-levelling compound?
The processing time varies depending on the product. You usually have between 15 and 45 minutes to apply and distribute the mass. Pay attention to the information provided by the manufacturer.
3. Can I apply multiple coats of leveling compound if one coat is not enough?
Yes, that is possible. However, allow the first coat to dry completely before applying another coat.
4. How long do I have to wait before laying the new floor covering on the leveling compound?
The waiting time depends on the drying time of the product, which is indicated on the packaging. Usually you have to wait at least 24 hours before you can lay the new flooring.
5. What safety precautions should I take when using self-levelling compound?
Wear suitable protective equipment such as gloves, safety goggles and a respirator when mixing and applying the compound. Also make sure there is adequate ventilation in the room to dissipate the fumes from the mass.
