PàP (Plâtre à Plancher : Gypsum plaster for flooring) is a traditional high-resistance gypsum plaster used to realise finishing screed.
PàP can be smoothed with trowel (“lissé“) or more likely sanded/polished (“poli“) or softly brushed (“lustré“).
When plished, it can be added with marble aggregates to create terrazzo-like floors.
In case of important thickness, a specific base coat is available : BàP (Base à Plancher)
