What is Silicone Render?

There are many different types of render on the market, all with different properties. The range includes older sand-cement style renders, to scratch renders, and thin coat renders. Silicone Render is a ‘thin coat render’, which means that it is applied on top of a basecoat at just a few millimetres thick. Silicone render is becoming ever more popular these days, so in today’s blog post we’re going to explaining a little bit about it.

Why choose Silicone Render?

There are some big advantages to using this product – there really is little competition when it comes to quality of finish. Let’s take a look at some of the major advantages:

  • Silicone is breathable – Where cement and acrylic renders completely seal off the wall and prevent it from breathing, silicone is very breathable.
  • Silicone is self-coloured – Unlike other renders that must be painted after curing, silicone render has the colour mixed into it, meaning just one coat and the job is done. Having the render pre-coloured means that it lasts longer and won’t show if it is scratched, as the colour runs through the whole top-coat. (for an idea of the cost of silicone render per square metre, read our dedicated blog post here)
  • Silicone is easy to apply – Where other renders have a painting stage, thin coats can be done in just a few hours on a properly prepared wall. Despite a slightly higher cost, your job will be done in much less time than a traditional render.
  • Above all else, silicone looks great! It leaves the property looking like a new house.

How is it applied?

Silicone is a one-application thin coat render. It is dead easy for a qualified renderer to apply this render to a fully prepared wall. On a typical wall, a basecoat should be applied to create a strong, stable and level surface with which to render. Once the base coat has dried, the silicone can be applied using a plastic float to create a thin and smooth finish. The thickness of the silicone top coat should be the same as the grain size of the render. So a 1.5mm Silicone Render will be 1.5mm thick on the wall. The layer has to be applied in one go on each elevation otherwise you could end up with patches and lines where the render has been joined.

There are 3 key characteristics that all silicone renders display, they are hydrophobic (repel water),  they are breathable and they are flexible. As you go down the list (i.e. from EWI-040 to EWI-075 and so forth), the renders show higher levels of these characteristics so basically you are getting a better product.

How much does Silicone Render cost?

Each of the silicone renders has a different price point which you can see below, but it is worth mentioning that all silicone renders are going to cost more than acrylic render, because you are getting a vastly superior product. 

Typically though, since a bucket of the 1.5m grain render covers 10m2, when you consider the other products required like basecoat and mesh, you are going to be paying between £10 – £15 per m2 – which is comparable to monocouche / scratch renders. 

How much thin coat render do you need for a typical house?

This is going to come down to the area of wall you are looking to cover. The render comes in 25kg pre-mixed buckets, and each bucket at our standard 1.5mm finish will cover around 8 square metres of wall. For an average semi-detached house of say, 80m, you are looking at around 10 buckets of render. If you go for a finer grain size of 1mm, the render will go further, covering 11-12m of wall each. Thicker 2mm render will cover less area, so you need to take this into account when you are working out the quantities you need.

  1. I had silicone render installed with Wetherby system a few years ago and I am really struggling to get a hold of the contractor who did the works, as I am trying to get the coloured render of the same colour to apply to the new extension. Is the render as in the silicone render you sell in the colours could be matched with the silicone render that has alreAdy been installed?

  2. I am looking to get a coloured render for my pebbledash property. From what I understand, i need to apply a basecoat layer to the existing peppledash and then put this coloured render on top. I guess my fear is that what if the pebbledash were to drop off of the wall, then the new render would also drop off. Is there anything I can do to secure the pebbledash in place better so i can be sure my new render finish isn’t ruined in the first week of putting it all on the wall?

    thanks for your help
