There is a wide variety of premixed renders for different situations. Some have a polymer additive to the traditional cement, lime and sand mix for enhanced water resistance, flexibility and adhesion.
Acrylic premixed renders have superior water resistance and strength. They can be used on a wider variety of surfaces than cement render, including concrete, cement blocks, and AAC concrete paneling. With the right preparation, they can be used on smoother surfaces like cement sheeting, new high tech polymer exterior cladding and expanded polystyrene. A few of these require activation with cement just prior to application.
Oz Rendering recommends the use of high quality Dulux rendering products.
Cement rendering
Cement rendering is the application of a premixed layer of sand and cement to brick, cement, stone, or mud brick. It is often textured, coloured, or painted after application. It is generally used on exterior walls but can be used to feature an interior wall. Depending on the 'look' required, rendering can be fine or coarse, textured or smooth, natural or coloured, pigmented or painted.
