earthen plaster

Earthen plaster is a blend of clay, fine aggregate, and fiber.

However, earthen plasters are often more labor-intensive than other forms of wall covering.

The wall paintings were executed on earthen plaster with the so-called secco-technique.

Sand provides structure, strength, and bulk to earthen plasters.

The walls are simply finished with a natural earthen plaster, and any carving in the ranma transom is kept simple.

Many of the walls were decorated with colored earthen plasters, which were the first to erode over time.

There are many possibilities of what material to use, including cement-based stucco, or lime or earthen plaster.

Earthen plasters are less toxic and energy intensive than many other wall coverings, which makes them appealing to the environmentally-conscious.

Earthen plasters are not approved by all local building codes, as some require the use of cement stabilizers or asphalt emulsion.

Earthen plaster is a rare wall covering in the developed world and there is a dearth of local experts for construction and repair.

Cactus juice also serves as a stabilizer in that it helps make earthen plasters more water resistant and more durable.

When bales are used to build or insulate buildings, the straw bales are commonly finished with earthen plaster.

Earthen plaster is usually applied to masonry, cob, or straw bale interiors or exteriors as a wall finish.

Dry straw, hemp fiber, cattails, coconut fiber, and animal hair are all suitable fiber choices for earthen plasters.

Pure earthen plaster (plaster without lime, cement, or emulsified asphalt) is applied to interior surfaces more frequently than exteriors.

Fluid ("cactus juice") extracted from Opuntia pads and stems, especially O. ficus-indica, is one of the most commonly used additives in earthen plaster.

The dōzō were built with a structural frame made of timber coated with a number of layers of earthen plaster on the walls, door and roof.

Cactus juice works well because it contains pectin, a water soluble long-chain carbohydrate that acts as the binding agent to increase the adhesion of an earthen plaster.

External waterproofing finishes for cob cordwood walls include lime-sand plaster, linseed coatings over earthen plaster, and Earthbind 100 compound (a waterproofing additive).

Pectin is also responsible for increasing the water resistance of an earthen plaster and has been used to augment lime plasters in both Mexico and the southwestern United States for hundreds of years.

Mudgirls specialize in using cob, as well as other natural material such as strawbale, driftwood, cordwood, earthen plasters and natural insulations, and recycled materials like window panes, car tires and glass bottles.

The support for wall paintings in made of earthen plaster, usually consisting of more than one layer of earthen plaster, in which the last layer was rendered as smoothly as possible.
