    Doing a job this evening. Subfloor is ceramics. I am down for screed dpm and screed as recommended by arditex! Never dpm a ceramic before?? I think it will only need one screed. Would you prime the floor before using a one part dpm or just dpm then screed?

    If the tiles are laid on a damp concrete you will need to do what Ardex have described
