Can I apply microcement on Fermacell?

Fermacell is a more robust alternative to board substrates and functions well when properly prepared. It is essential to monitor the joints, flatness, and have a clean, primed surface. The key factor is not only the material of the substrate but also its condition. Before application, check for strength, flatness, grease, dust, cracks, and any movement. If the surface is considered risky, it is better to reinforce it or first create a test area.
