Not all surfaces are equal when choosing flooring materials for underfloor heating. Some might crack, warp, or block the heat.
That’s where microcement stands out—and Forcrete microcement, in particular, makes a perfect match for underfloor heating systems.
Let’s examine why this seamless, stylish surface is a design win and a wise, functional choice for modern heated flooring.
What makes microcement suitable for underfloor heating?
Microcement is a thin, cement-based coating applied in layers, typically only 2–3mm thick. Its low thermal resistance and high thermal conductivity mean heat passes through it efficiently, warming your room faster and more evenly than many traditional flooring materials.
Forcrete microcement takes this a step further. Our formulation includes advanced resin technology, giving it movement tolerance and strength, which are key qualities for surfaces that expand and contract with temperature changes.
Does microcement crack with underfloor heating?
Cracking is a common concern, and a fair one. The last thing you want is a beautiful finish compromised by cracks due to thermal movement. With standard microcement systems, poor flexibility can be a problem. But Forcrete is different.
We’ve engineered our system to work in harmony with heated substrates. Thanks to our unique polyurethane resin base, Forcrete microcement offers exceptional flexibility that accommodates movement without cracking.
Is microcement good for heat retention?
Absolutely. One of the standout features of microcement is its ability to retain heat, even after the heating system is turned off. This thermal mass effect helps improve energy efficiency and keeps your space warm for longer.
Combined with Forcrete’s dense, contemporary finish, this system heats up quickly and retains that warmth, making it ideal for colder months or homes looking to improve their heating performance.
How long after installing underfloor heating can I apply microcement?
You should wait 14 to 21 days after installing underfloor heating before applying microcement. This period allows the screed or substrate to fully cure and ensures that any moisture from the installation process has evaporated.
To prevent cracking or shrinkage in the substrate, it is essential to follow a gradual heating cycle, starting at a low temperature and increasing it slowly over several days.
Before applying microcement, ensure the surface is dry and stable, with a moisture level of less than 3%. The substrate can be primed and prepared for microcement application at this stage.
Our professional installers around the world will ensure that your microcement has maximum adhesion, resilience to thermal expansion, and long-term performance over your heated flooring.
