Can I apply microcement onto MDF?

MDF is mainly used for furniture and decorative elements. It is necessary to remove dust, prime the surface, and properly seal the edges, as the edges absorb the most and are often the weakest point. It is not only about the material of the substrate but primarily about its condition. Before application, check for strength, flatness, grease, dust, cracks, and any movement. If the surface is risky, it is better to reinforce it or first create a test area. For better results, an HDF board is preferable, as it is stronger.
