Stuc Pierre® (more or less fake stone or faux-pierre) is a French gypsum based render procédé used to simulate – or more precisely to idealize – a classical limestone masonry.
Described for example by Blondel (1705 – 1774) but far older, Stuc Pierre® was widely used in French classical architecture and is present in most Hôtel Particuliers of Paris, in exterior as well as interior.
Nowadays, Stuc Pierre® is used in restoration of heritage building (Boston, New York area) and new classical architecture, both commercial or residential.
To summarize, Stuc Pierre® process use a high-quality mass-tinted gypsum render. It is applied on the support and perfectly evened. Once hard enough, fake joints are carved in with a chemin de fer (a specific kind of narrow plane) and then filled with white same render. After drying, a final sanding cleans the “joints” and gives the stone-liked texture.
We developed several versions according the different situations (interior/exterior, supports and plastering/casting/running, etc …. ). Concerning American market, the most used version are casting (for molding) or veneer (on gypsum boards) versions. More infos in Stuc Pierre Data Sheet.
