Polymer render is an acrylic-based rendering system with added polymer (a group of natural and synthetic substances made up of large molecules). It comes in a wide range of colours and textured finishes and is usually available already mixed. It can be applied to various surfaces, including brick, concrete, and masonry, for both exterior and interior walls.

What is Polymer Render?

Polymer render is an acrylic-based render with added polymer molecules that make it stronger and more flexible. It is specially designed to be applied over fibre cement sheeting, which covers the exterior or interior of a residential, commercial, or industrial building or complex.

It comes pre-mixed and ready to use, usually as a one-coat application with no base coat required. It is also available in different colours and textures. It typically has a more sticky texture than other renders, which makes it ideal for use on more tricky materials.

Where is Polymer Rendering Used?

Polymer rendering is used on a variety of different surfaces and in different situations:

  • Residential buildings: Polymer render is versatile and visually appealing, coming in various colours and finishes. This makes it ideal for residential properties, as there’s sure to be an option that suits every design brief. It also bonds exceptionally well with various surfaces, including concrete, plasterboard and brick.
  • Commercial properties: Polymer render’s excellent bonding capabilities and flexibility make it easy to use for larger-scale construction projects that may be subject to more structural movement over time.
  • Facades and architectural finishes: Another popular way to use polymer render is to enhance the design of architectural finishes, such as reliefs, patterns, and texture, on a home’s facade or interior and exterior surfaces.

Benefits of Polymer Rendering

The benefits of polymer rendering include:

  • Water resistant: Polymer render is water resistant on its own, making it perfect for use in bathrooms and laundries.
  • Highly adhesive: Polymer render bonds well with most materials, making it suitable for most exterior and interior applications.
  • Weather resistant: Polymer render is durable and resistant to most weather conditions, including rain, wind and heat.
  • Long-lasting: if it is applied correctly, polymer render can last for decades.
  • Pre-mixed: Polymer renders tend to come already-mixed, making application.
  • Requires little maintenance: Polymer render requires little maintenance besides a thorough cleaning every now and then.
  • Flexible: The mix of polymer and acrylic molecules results in a more flexible render that allows for the natural movement of a building without cracking.
  • Variety of finishes: The additional fillers in polymer render allow it to have a wide range of finishes, including different colours and textures that suit many design preferences.
  • Suitable for various materials: A polymer render can be applied to almost any surface, including brick, concrete, plasterboard, cement blocks, fibre cement sheeting and polystyrene.
  • Can fix minor imperfections: Polymer render can also be used to cover up or fill any small imperfections, including small dents, cracks, or uneven surfaces.

Disadvantages of Polymer Rendering

The downsides of polymer rendering include the following:

  • More expensive: The outright cost of polymer render is slightly higher than other rendering options due to its additives and unique properties. However, the more expensive outright cost is worth it in the long run.

Application of Polymer Render

The steps to apply polymer render include:

  1. Cleaning the surface: Before applying any render, it is important to clear the surface of any loose debris, dirt and dust.
  2. Primer: A primer might need to be applied on some surfaces for easier bonding (depending on the surface material).
  3. Application: Apply the polymer render mixture with a trowel and a sponge or float to ensure a smooth surface.
  4. Curing and drying time: Allow the render to dry for at least a few hours.
  5. Sealer: Go over the render with a protective sealer to make the render even more durable and water resistant.
