Metal reinforcing lath can also be useful over badly deteriorated concrete substrates. On one project we were involved with, the concrete floors were unstable and full of cracks. After making all of the necessary crack repairs, we attached metal lath with an air-driven nail gun directly to the surface.

Keep in mind that even after performing all of the necessary prep work, it is common for cement-based toppings installed over wood to exhibit minor cracking. But in the case of an underlayment, this is usually not a concern since it will be covered up with some other flooring material.
