Ensure tools and mixing bucket are clean and free from set pieces of render. Gradually add 5kg of render to 800ml of clean water. Mix for 2 minutes until a smooth mix is achieved.

Apply the render using the filling knife to the required depth (max. 25mm) and finish. Avoid “feathering out” too thin. Remove the masking tape and any excess material and allow to dry. Using a sponge lightly rub the render to achieve the desired effect and to blend with the existing material. Clean tools and bucket using warm soapy water immediately after use.
