Floor heating sand/cement screed

Floor heating screed sand/cement. What should you pay attention to?

When installing underfloor heating on a sand/cement screed, there are several components to consider to ensure a properly functioning system. Four things are important:

Preparation
Installation
Screed requirements
Aftercare

Installing floor heating on sand/cement screed begins with preparation

1. Preparation

Before you begin, make sure there is adequate thermal insulation under the underfloor heating system. This will prevent heat from escaping downward and ensure that heat is conducted upward, into the room. In addition, it is important to install edge insulation along the walls. This edge insulation not only helps prevent cold bridges, but also captures the expansion of the screed, minimizing cracks and other damage.

2. Installation for underfloor heating screed

Laying plan: Follow the floor heating installation plan carefully, keeping in mind the recommended pipe spacing (usually 10-15 cm) for even heat distribution.
Fastening: ensure that the underfloor heating pipes are securely fastened to the reinforcement mesh or installation plates so that they cannot move during the pouring of the sand/cement screed.
Reinforcement: Consider using reinforcement netting to minimize shrinkage and cracks in the screed.

3. Requirements for sand cement screed

Thickness: The screed should have a minimum thickness of 5-7 cm above the pipes to spread heat evenly and provide sufficient strength.
Mixture: Use a sand/cement mixture with the correct ratio (usually 1 part cement to 4 parts sand) and add plastic fibers if necessary to improve strength and shrinkage resistance.
Application: The mixture must be well mixed and homogeneous. If necessary, use a floor pump for even distribution of the screed.

4. Aftercare of the sand cement screed

After pouring, aftercare is very important. The screed must cure sufficiently before you start using the underfloor heating system. This can range from 28 days to six weeks, depending on conditions and the mixture used. It is also crucial to warm up the underfloor heating slowly.

Increase the temperature by five degrees Celsius daily to prevent cracking due to thermal stresses. Also make sure the screed is sufficiently dry before you apply the final flooring. Measure the moisture content with a hygrometer; the screed should usually have no more than 2 to 3 percent moisture.
