Preparing for the Task

Understanding the Materials

Before starting, familiarize yourself with the rendering mix components. Ensure you have the right type of sand, cement, and tools for the job.

Surface Preparation

  • Cleaning: The surface must be clean and free from debris.
  • Repairing: Fix any cracks or damage before applying the render.
  • Priming: Use a primer if necessary to help the render adhere to the surface.

Mixing the Render

Achieving the Right Consistency

The render should be of a consistency that is easy to apply but not too runny. Typically, a 1 part cement to 4 parts sand ratio is used.

Mixing in Small Batches

Mix in small batches to maintain consistency and prevent the render from drying out before use.

Application Techniques

Applying the First Coat

  • Thickness: Apply the first coat evenly, around 5-8mm thick.
  • Tool Use: Use a trowel for application and ensure even coverage.

Scoring the First Coat

Once the first coat is slightly set, score it to provide a key for the second coat.

Adding the Second Coat


Wait for the first coat to set, but not completely dry, before applying the second coat.

Thickness and Smoothness

Apply the second coat, ensuring it's smoother and fills in any gaps or lines from the first coat.

Finishing Touches

Creating Textures

If a textured finish is desired, use tools like sponges or brushes while the render is still workable.


Allow the render to cure slowly, avoiding rapid drying which can cause cracks.

Post-Application Care

Protecting the Render

In the days following application, protect the render from extreme weather conditions.


Regularly check and maintain the render to ensure its longevity.

Common Mistakes to Avoid

Inconsistent Thickness

Apply the render consistently to avoid weak spots.

Rushing the Process

Give each stage the necessary time it needs for the best results.
