The word "roughcasting" is spelled with three distinct sounds: /rʌf/ for the initial sound, /kæst/ for the middle consonants, and /ɪŋ/ for the final syllable. The sound /rʌf/ is similar to "ruff" and the sound /kæst/ is similar to "cast." The final syllable, /ɪŋ/, is pronounced with the same sound as "ing." Roughcasting is a type of exterior finish for buildings that involves applying plaster or mortar and pebbles or gravel to create a textured surface.
Roughcasting is a term used in the construction and architecture industries to refer to a technique for finishing the external façade of a building or structure. It involves the application of a rough, textured mortar or plaster coating to the surface of the walls.
Typically, roughcasting is performed by skilled tradesmen known as roughcasters. They begin by preparing the wall surface, removing any loose particles or debris. Then, a base coat of mortar or cement, mixed with sand and water, is applied onto the surface using a trowel or a similar tool. The base coat is usually roughened with a broom or brush to create a textured appearance.
After allowing the base coat to partially dry, a top coat of a similar mixture is applied over the surface. This top coat can be pigmented or dyed to achieve a desired color, or left as a neutral shade. Once applied, the top coat is often scored or marked with a rake or comb tool to create further texture and to provide a key for any subsequent paint or staining.
Roughcasting serves both functional and aesthetic purposes. It adds an extra protective layer to the walls, shielding them from external elements such as weather, moisture, and impact. Additionally, the textured appearance produced by roughcasting can enhance the visual appeal of the building, often giving it a rustic or traditional look.
In summary, roughcasting is a construction technique in which a rough plaster or mortar coating is applied to the exterior walls of a building to provide protection and create a textured, visually appealing finish.
The word "roughcasting" has its roots in the Middle English term "roughcasten", which originated from the Old English word "reoh", meaning "rough" or "harsh", and "casten" which means "to throw" or "to form". The word "roughcasting" refers to the technique of applying a rough layer of plaster or stucco to a building's exterior walls, thereby creating a rough or textured finish. The term has been in use since the late 16th century.
