Lathing is a construction technique used to create a supportive framework for applying plaster or other finishing materials to walls, ceilings, or other surfaces. It involves the installation of thin, narrow strips of wood or metal, known as lath, onto a structural surface to create a stable and level base for the application of plaster.
The process of lathing begins with the selection and preparation of the appropriate lath material, which can vary depending on the specific application and desired finish. Wooden laths are most commonly used, made from materials such as pine, spruce, or fir, while metal laths made from materials like expanded metal or diamond mesh are suitable for more specialized purposes.
The lath strips are then fastened horizontally or vertically to the structural surface using nails or other appropriate fasteners. Careful attention is paid to spacing and alignment to ensure a consistent and smooth surface. Once the lathing is complete, a wet plaster mixture is applied to the lath, filling in the gaps and creating a durable and even finish.
Lathing is an important step in construction and renovation projects as it provides the necessary support for the application of plaster or other materials. It ensures a level and stable surface, preventing cracks and other forms of damage. Additionally, the lath helps to create a bond between the plaster and the underlying structure, enhancing the strength and longevity of the finished surface.
