Gypsum plaster, or the “Plaster of Paris”, is produced by heating gypsum to about 300 °F.

When the dry plaster powder is mixed with water, it re-forms into gypsum. The setting of unmodified plaster starts about 10 minutes after mixing and is complete in about 45 minutes, so timing and speed of plastering are imperative.

A large gypsum deposit discovered in Paris in the 1500’s coupled with the queen of Paris’ ordering of all wooden structures to be coated with plaster as a safety measure after the great fire of 1666 in London, led to the name “Plaster of Paris”.

Because of its violent exothermic reaction, gypsum plaster forms a very hard and durable finish, perfect for simulating the appearance wood, stone, or metal. The addition of sealers and wax’s only accentuates gypsum plasters beauty.

The craft of “tadelakt” has its origins in Morocco. The word “tadelakt” comes from the Arabic verb “dlek” which means to rub in. As the plaster is curing, a polished stone is used to rub and smooth the surface, and integrate olive oil soap into the material. The integration of the soap into the curing lime creates a hydrophobic reaction.

Traditionally, this plaster system was used to keep water cisterns pure and clean. Over time, this waterproofing method evolved and is now a timeless and cherished plaster that celebrates both form and function.  It can be applied in showers, backsplashes, on countertops, and bathtubs.

The tadelakt technique, handed down verbally from generation to generation is more of a system than a product and takes years to learn and perfect. New Age Artisans is proud to have been practicing tadelakt since 2008, and has completed countless showers around the Northwest, and currently is the only installer in the area.

Lime is one of the most ancient and vital materials used by humans. Many languages have a word for calcium oxide. In Latin it is “calx”, from which the name of the element calcium is taken.

Limestone is a naturally occurring and abundant sedimentary rock consisting of high levels of calcium and magnesium carbonate, along with small amounts of other minerals. It is extracted from quarries and underground mines all over the globe.

Through an amazing process called the lime cycle, this extracted mineral is heated to form “quicklime.” The addition of water to quicklime forms “hydrated lime”, or “Type S” as it is commonly referred to. The combination of carbon dioxide and atmospheric conditions brings Type S back to limestone, thus making lime a perfect material for plaster. Many plasters are made from limestone, including but not limited to exterior stucco, venetian plaster, and the coveted “Tadelakt” system.

Clay

Clay is one of the oldest building materials on Earth. About 50% of the world’s population, in traditional societies as well as developed countries, still have clay as a vital facet to their structures. In addition to bricks, mortar, pipes, and in some cases foundations, clay makes an excellent wall finish.

Clay breathes with changes in temperature and humidity, can be pigmented with countless color options, both bold and subdued, and is very repairable, compared to most other plaster options.

Clay plasters are bonded by mechanics rather than a chemical set. This mechanical bond give clay a large open time, allowing the applicator to achieve a smooth and flawless finish.

New Age Artisans has completed over 500,000 square feet of installation of American Clay plaster.
