Rendering refers to the application of plaster to an externally exposed surface. When it comes to plastering, cement plaster and lime plaster are commonly used. Adding a finished mortar finish to a wall or similar structure is an important part of protecting the joints from atmospheric agents as well as improving the visual appearance. As it is difficult to detect defective points in a whole structure, pointing is often performed on the whole structure or on the whole wall. In addition, adjacent joints may also require repairs to a depth of twenty millimeters.
