Applying render

Ensuring that your final product is even and set is key to achieving an appealing, well-protected home. The real work starts even before any formulations are applied, paving the way to excellent results that last for years on end.

Each medium has its own requirements when it comes to preparation. With the right pre-care our RSA products can truly shine, covering your home’s interiors or exteriors with high-quality plaster that adds to its appeal.

Find out what you can do to maximise the performance of your new builds and renovations, allowing you to enjoy the benefits far into the future.

Prep for excellence

Being informed is key to achieving a high-quality finish on projects. To help you understand which products pair best with the exposed material, we’ve put together handy, clear guides that aid in planning out projects.

To get a sense of the methodology used, simply select the substrate you’re working with and find material information detailing surface prep and more. You’ll also find examples of RSA applied to finished projects under the relevant section.

Descriptions are available for common surfaces used in Australia, including:

  • Masonry brick & block
  • FC – Fibre Cement Sheeting
  • EPS – Expanded polystyrene
  • PC Sheet
  • PVC
  • (AAC)Autoclaved Aerated Concrete
  • Concrete

Match the guide to the material you’re working with and learn what it takes to create a high-quality finish.
