The definition of rendering is the application of a plaster-based finish for the external walls of a building that gives a smooth finish and protects the structure’s brickwork—traditionally applied in two or three coats which make surface cracks less likely to develop. There are several different types of render that the homeowner can choose from that include cement renders, polymer renders, and lime renders. The job of rendering is something generally completed by a professional, but with the correct set of tools and excellent prior research, an amateur can do.

What Are the Benefits of Rendering?

We have already mentioned that rendering protects a building’s brickwork from the elements, but there are other plus points to applying render to your home. Nearly 30 per cent of the energy used to heat a home is lost through the external walls; it is possible to improve the thermal efficiency by utilising a specific acrylic-insulated render that forms a sealed layer keeping in the heat. A further benefit is an aesthetic improvement gained by applying render to your home; through-coloured renders can add to the overall look with the bonus of not needing to paint afterwards.

Having The Correct Tools

As a motivated amateur looking to render your home, it is crucial to have the right tools to enable you to succeed; the rendering tools you would need are as follows –

  • Square Notched Trowel is an essential tool primarily used to ensure the base coat of render when applied at the right thickness.
  • Bucket Trowel – this tool is handy for moving or mixing render.
  • Plastic Render Float – used to get a textured finish if required.
  • Sponge Float – this tool smooths out any trowel lines or imperfections after applying the render.
  • Corner Trowel – used to achieve a seamless finish around tricky corners, a vital tool for both base and top layers.
  • Speedskim – while not essential, it is a timesaver by covering a larger area than the regular trowel, smooth flat surfaces in less time and energy.

The appropriate Ppe equipment should accompany this tool listing; gloves, hard hat, boots, and goggles are the minimum, with a first aid kit always to hand. Purpose-made mixing buckets is the recommendation, as is hiring a render mixing machine; you can mix render manually, but it is hard work, especially if you have a large amount to get through.

The Rendering Process

I cannot accurately detail the complete rendering process within this article. I recommend utilising the wealth of how-to guides available on the internet to gain valuable information on how to proceed. I will, though, briefly touch on the different steps of the process to give you some idea; these are –

  • Preparation of the surfaces to make sure they are clean.
  • Mix your render correctly, following the manufacturer’s instructions.
  • Application of the base coat of render.
  • Further additions of second and third coats
  • Finishing topcoat for the desired effect.

You should allow between two and three days to fully complete the process of applying the several layers of render, you will need good weather, so this is also something to consider.

If you are considering tackling the rendering of your home, I hope this information has given you an excellent starting point from which to succeed.
