Preparation and Application
Initial Steps and Processes
Preparation is a crucial step in the application of lime renders. The wall surface must be meticulously cleaned, ensuring it is free from vegetation, contaminants, and reasonably dry throughout the wall mass. Structural integrity is paramount; thus, the masonry and bedding mortars should be in good condition. Any loose or damaged pointing should be raked out and replaced prior to rendering. Achieving the right level of dampness is essential—while the surface should be thoroughly damp, it must not be wet. This balance is necessary to achieve a strong bond, as a certain amount of suction is required for lime mortars to adhere and stiffen properly.
The application of hydraulic lime plasters should aim to minimize shrinkage and rapid drying. Techniques such as controlling the environment to prevent rapid drying and ensuring proper bonding with the background are critical throughout the plastering process. Lime rendering is a traditional method that demands skill and expertise, making it essential to work with a qualified professional to ensure a successful application.

Application and Techniques
The application of lime render involves a meticulous process of applying a series of coats, starting with a scratch coat, followed by subsequent coats, and finishing with a final coat. Proper preparation and application processes are crucial, including the use of plaster and the prevention of cracks. Each coat is applied using a steel trowel or a specialized tool, such as a lath scratcher, to create a strong bond between the render and the wall. The use of hydraulic lime is common in lime rendering, as it provides a strong and durable finish that can withstand the elements.
One effective technique is throwing the render onto the wall, rather than applying it with a trowel, which can help to create a more even and consistent finish. The base coat is essential for establishing a solid foundation, and keying techniques, such as forming a key and using diamonds, are important for proper adhesion. Forming a key is crucial for ensuring a strong bond between the plaster and the substrate, which enhances the durability of the plaster work. Additionally, the use of a devil float or a second coat can help to achieve a smooth and even surface, while also providing additional protection against the elements. Proper preparation of substrates, including brick, and protecting windows during the rendering process are also crucial. Allowing a suitable period between coats ensures proper adhesion and minimizes cracking. These techniques ensure that the lime render not only looks aesthetically pleasing but also offers long-lasting durability.
