Can I apply microcement on a Cetris board?

Cetris is a suitable board substrate, often used even for demanding or exterior constructions. However, it must be properly secured and the joints must not be left without reinforcement. It is not only about the material of the substrate, but primarily its condition. Before application, check the 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. The Cetris board is suitable as a substrate for exterior applications.
