Advanced Techniques and Innovations in Cement Rendering

As an applicator, refining your skills and staying ahead of industry trends can set you apart. In this post, we discuss new techniques in cement rendering. These techniques include multi-layer rendering, creating different textures and finishes, and using additives for improved outcomes. With these tips, you’ll be well-equipped to cater to sophisticated client demands and deliver superior results.

Multi-Layer Cement Rendering: Building a Strong Foundation

Multi-layer cement rendering is an essential technique that every applicator should master. Multiple layers are applied for various purposes, such as achieving a smoother texture, increasing durability, and ensuring a consistent, high-quality appearance. Each layer contributes to the overall effectiveness and aesthetics of the final render.

Base Coat (Scratch Coat): The initial layer, often called the scratch coat, ensures strong adhesion to the substrate. Applicators typically apply it at a thickness of around 10 mm and score it to provide a key for the subsequent layer. This coat is crucial for achieving a solid foundation.

The intermediate coat (Brown Coat): offers structural integrity and allows for customisation to enhance insulation or impact resistance. The brown coat should be applied evenly to ensure a uniform thickness.

Final Coat (Top Coat): The visible layer is where your skills as an applicator shine. Mix the top coat with colourants if you want to add colour. The top coat is typically 2-4 mm thick. Techniques such as troweling, stippling, or creating swirl patterns can add aesthetic value and unique textural effects.

Achieving Different Textures and Finishes in Cement Render

Creating a diverse range of textures and finishes allows you to offer outstanding solutions. Here are some popular techniques that can help you stand out:

Sponging: Using a damp sponge to pat the final cement render layer creates a textured yet even surface. This technique is ideal for modern, minimalist designs.

Bagging: This is a technique used to create a rough finish on walls. To achieve this look, apply cement render using a hessian bag. This textured finish is perfect for Mediterranean or Tuscan-style homes.

Brushing: Brushing the final render layer with a stiff bristle brush can create unique grooves and striations. This technique offers a weathered look, suitable for heritage buildings.

Smooth Finish: A smooth finish requires careful troweling of the final coat. Achieving a polished surface is a skill that requires precision and patience.

Swirl Finish: Swirling the trowel in circular motions across the surface creates a beautiful, patterned finish that adds visual interest to any facade.

Texture Coatings: Advanced texture coatings, like Rockcote’s Acrylic Texture, provide excellent durability and allow applicators to achieve consistent finishes easily.

Use a High-Quality Blend with Additives

Rockcote manufactures thousands of kilograms of render and carefully controls the blend of additives for improved application properties. Rockcote’s innovative use of additives ensures superior workability, strength, and finish quality, allowing the applicator better workability. This precision in blending results in consistent, high-quality products that deliver outstanding performance every time.

Advanced Tools and Equipment for Efficient Cement Rendering

In addition to mastering techniques, having the right tools is crucial for efficient and high-quality cement rendering.

Power mixers ensure uniform mixing of cement render, additives, and colourants, providing reliable and consistent quality every time.

Spray rendering machines significantly speed up application processes, improve coating consistency, and reduce labour costs. We highly recommend using them, particularly for large-scale projects.

Laser levels ensure perfectly straight render lines, particularly important for achieving smooth finishes or intricate patterns.

Float and Sponge Tools have a variety of floats and sponge tools which allows you to create different textures and finishes easily.

Innovating with Pre-Mixed and Ready-to-Use Cement Renders

Pre-blended and ready-to-use cement renders, such as Rockcote Quick Renders, simplify the application process by reducing on-site preparation time. Some benefits of this product type include: 

Consistency: Pre-blended renders offer consistent quality, ensuring even finishes across the entire project.

Time-Saving: Applicators can focus more on applying the render and less on preparation, improving productivity.

Reduced Waste: Exact quantities can be ordered, reducing waste and minimising environmental impact.
