Can I apply microcement to plywood?

Plywood can be used on stable elements, but it is important to remember that applying the screed is a wet process. Unprotected edges or cuts can absorb moisture and the board may warp. It is therefore not only about the type of substrate, but mainly 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 make a trial area. It is important to bear in mind that the application of screeds involves moisture and plywood can warp. Similarly, on any cut edges, waterproofing or protection is necessary.
