Rough wall plastering is one of the oldest plastering techniques. Its basic concept can be traced back centuries to buildings constructed of natural materials, including limestone and sandstone. The oldest known examples of this style of plastering were found in the tombs of ancient Egyptian pharaohs, dating to around 1000 B.C.
Modern rough wall plastering is much the same as it was in ancient times, using the same natural materials as well as sand, lime, and water as binding agents. This type of plastering is often found in older homes, especially those that were built before the 20th century. The style is used not only for aesthetic purposes, but also to add a layer of protection to walls.
The basic process of applying a rough wall plaster is relatively simple yet time-consuming. Before applying the plaster, it is important to ensure that the underlying surface is sound and free of any imperfections or cracks. Once the wall has been prepped and cleaned, a bonding layer of wet plaster mix can be applied. This mix is typically a combination of lime, clay, and sand. Application is done in several layers, with each layer being allowed to dry before the next is applied. The thickness of the layers will depend on the desired effect and the size of the underlying surface.
The next step is to apply the texture, which is often done by hand. A variety of tools can be used to create a range of patterns and textures, such as trowels, sponges, brooms, or rags. It is possible to purchase stencils which can be used to create intricate, detailed designs. Finally, a thin layer of finishing plaster is sometimes added to help smooth and seal the rough wall plaster.
Rough wall plastering requires patience, skill, and knowledge but can be a relatively easy process if the right tools and materials are used. Lime mortar is one of the best materials to use when applying a rough wall plaster. It is strong, stable and resistant to cracking, making it an excellent choice for a long lasting finish. Applying a rough plaster serves both an aesthetic and practical purpose, allowing homeowners to create a unique, eye-catching wall finish while also protecting the wall from water damage, staining and other issues.
