Unlocking the Warmth: The Rise of Underfloor Heating

More and more people are turning to underfloor heating as a modern and efficient way to keep their homes warm. It provides superior thermal comfort and long-term cost savings compared to traditional radiators.

However, not all flooring materials are compatible with underfloor heating systems. This is where microcement steps in as the ideal solution.

Why Choose Underfloor Heating?

Underfloor heating offers several benefits, including:

  • Enhanced Thermal Comfort: Underfloor heating provides even and consistent heating throughout a room, creating a cozy and comfortable atmosphere.
  • Economic Efficiency: It is a cost-effective way to heat your home, reducing energy consumption and lowering heating bills.
  • Space Optimization: Eliminates the need for bulky radiators, allowing for more flexible interior design options.

The Compatibility of Microcement with Underfloor Heating

Microcement is gaining popularity as a flooring material for underfloor heating due to its exceptional properties:

  • Continuous Coating: Microcement is a continuous surface, ensuring uniform heat distribution without cracks or interruptions.
  • Excellent Heat Resistance: It has high thermal conductivity, efficiently transferring heat from the underfloor heating system.
  • No Cracking: When correctly applied, microcement remains crack-free, even when exposed to the heat of a radiant floor.

Step-by-Step Guide for Applying Microcement on Underfloor Heating

Heating the Floor

  • Turn on the underfloor heating at least 4 weeks before microcement installation.
  • Gradually increase the water temperature over several days.
  • Turn off the heating 48 hours before starting the microcement installation.
  • Ensure the maximum floor temperature does not exceed 18ºC.

Application of Microcement

  • Microcement should be applied on fully set cementitious mortars (approximately 3-4 weeks after installation).
  • Verify that the mortar is nearly dry (maximum 5% humidity) before applying microcement.

Turning On the Heating Again

  • Wait at least 48 hours after microcement application before restarting the heating.
  • Increase the temperature gradually, raising it by 5ºC daily.
  • Ensure the relative humidity in the room remains adequate.
  • Avoid blocking heat flow with carpets or furniture.

Advantages of Microcement with Underfloor Heating

Here are some compelling reasons to choose microcement for your underfloor heating system:

  • Low Consumption: Microcement is energy-efficient, reducing heating costs during the colder months.
  • Thermal Comfort: Achieve a harmonious balance between room and body temperature.
  • Resistance and Thermal Conductivity: Microcement’s durability and conductivity make it ideal for underfloor heating.
  • No Cracking: Properly applied microcement won’t crack, ensuring longevity.
  • Continuous Tiling: Microcement creates a seamless finish, enhancing visual continuity.

Potential Problems and How to Avoid Them

To ensure a successful microcement installation over underfloor heating, consider these factors:

  • Quality Matters: Invest in high-quality microcement to prevent issues.
  • Follow the Protocol: Strictly adhere to the heating protocol to avoid complications.
  • Address Subfloor Issues: Repair any subfloor cracks before installation.
