Slaked lime plaster
This is what the plaster walls of your great grandparents’ house were made of. Starting with the wooden slat, a coarse “scraping layer” (plaster mixed with aggregates preventing shrinkage, like horsehair) was applied, followed by a “brown layer” (plaster mixed with sand) and finally a thin layer of smoothing. Composed of limestone cooked at extreme temperatures to remove all impurities, hydrated or slaked lime plaster comes in the form of aged putty, so, unlike other options, you don’t have to mix it by hand and you are not under a time constraint to apply it.
Pure white in its basic form, it is now available in a wide range of colors. Left unpainted, like clay plaster, it absorbs and releases moisture – and unlike clay plaster, it can be used in kitchens and baths (but should not be exposed directly to water ). If desired, a protective layer of beeswax or Marseille soap can be added.
Architectural curators Master of Plaster of Columbia, South Carolina, specialize in slaked lime plaster, and resident designer Lauren Dillon is a source of information on why, where and how to use it. She explains: “After being applied, hydrated lime plasters go through a process called hardening in which they don’t necessarily dry like clay or paint, but they absorb carbon dioxide and complete the lime cycle on your surface, basically going back to stone – so when people say lime plaster looks like stone or marble, it’s because it really is. »Photograph of Justine Hand for Remodelista.
The project presented here was created using fine-grained plaster from the line not only on the walls but also on the floor. By the way, the corners are the most delicate with a trowel and, once finished, they are the most fragile area and prone to chipping.
