Earthen Plaster - Advantages and Disadvantages of Earthen Plaster

Advantages and Disadvantages of 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 also easily repaired and inexpensive. Earth plasters resist water penetration but are permeable to water vapor. However, earthen plasters are often more labor-intensive than other forms of wall covering. If the mix is not correct in component proportions, then many other problems may occur, such as dusting and cracking. 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.
