Finishes - Can a separate polished screed be used over the Sublime Floor?

Polished screeds such as Micro-Cement or resin based products are not ideal over a Limecrete floor as they will effectively seal the top surface of the limecrete, see - Can non-breathable finishes be used over the Sublime Floor?. Whilst not ideal, some projects will have a requirement for these finishes, they can be installed over the Limecrete if enough time is allowed for the Limecrete to dry, however there could be some issues with differential expansion and the flexibility of the materials. As the floor finish is non-breathable it is worth considering if a concrete slab would be more appropriate and have fewer compatibility issues with the screed Can I use a concrete slab over the Glapor RFG?
