Can Microcement be used with Underfloor Heating?

Yes, microcement can be used with underfloor heating systems. Its compatibility with underfloor heating is one of the many reasons it is a popular choice for flooring in modern homes and commercial spaces.

Here are the key points to consider when using microcement with underfloor heating:

 

Benefits of Using Microcement with Underfloor Heating

 

Thermal Conductivity:

Microcement has good thermal conductivity, which means it efficiently transfers heat from the underfloor heating system to the surface. This ensures an even and comfortable temperature distribution across the floor.

 

Flexibility:

The polymers in microcement provide flexibility, which helps the material withstand the expansion and contraction caused by temperature changes. This flexibility reduces the risk of cracking due to thermal stress.

 

Seamless Finish:

Microcement creates a seamless surface without joints or grout lines, which helps in evenly distributing heat and maintaining consistent temperatures across the floor.

 

Thin Application:

The thin application layer of microcement (typically 2-3 mm) allows for efficient heat transfer and quick warming of the surface. It also minimizes the additional height added to the floor, which can be beneficial in renovations where floor height is a concern.

 

 

Installation Considerations

Proper Substrate Preparation:

Check the minimum thickness of screed or any substrate over underfloor heating with manufacturer before calculating heights of new floor. 

Ensure the substrate is stable and free of any existing cracks. Any movement in the substrate can lead to issues in the microcement layer, especially when combined with the heating and cooling cycles of underfloor heating.

 

Insulation:

Proper insulation beneath the underfloor heating system is crucial. It ensures that the heat is directed upwards into the room rather than being lost downwards.

 

Gradual Heating:

When using underfloor heating with microcement for the first time, it's important to gradually increase the temperature. This allows the materials to acclimate and reduces the risk of thermal shock, which can cause cracking.

 

Professional Installation:

Given the technical requirements of both underfloor heating and microcement application, it's advisable to hire professionals with experience in installing both systems. This ensures that the installation is done correctly and reduces the risk of future issues.

 

Curing Time:

Allow adequate curing time for the microcement before turning on the underfloor heating system. Typically, this involves waiting for at least two weeks after the final application of the microcement to ensure it has fully cured and hardened.

 

Maintenance Tips

Temperature Control:

Avoid setting the underfloor heating to very high temperatures. Keeping a moderate and consistent temperature helps in maintaining the integrity of the microcement.

Regular Cleaning:

Clean the microcement surface regularly with mild soap and water to maintain its appearance and longevity. Avoid using harsh chemicals that can damage the sealant.

 

Conclusion

Microcement is an excellent choice for use with underfloor heating systems due to its good thermal conductivity, flexibility, and seamless finish. Proper installation and maintenance are key to ensuring that the microcement performs well and remains durable when combined with underfloor heating. By following the recommended practices, you can enjoy the benefits of both a stylish microcement floor and the comfort of underfloor heating.
