Coloured Render Cost Per Square Metre

Here at EWI Store  we offer a vast range of coloured renders to suit all tastes. We also offer a same-day coloured render mixing service, so you can match the colour to your existing render or simply find the shade that you love. Our coloured renders can also be matched to NCS colours as part of our colour matching service! Buying render with us means that you can get the colour and finish that is right for you.

Choosing a coloured render for your home is a big decision to make, which is why we offer colour charts and render tester pots. However, once you’ve made the all-important decision of which coloured render to choose, how much will it cost you?

How much Coloured Render will I need?

To work out exactly how much coloured render you will need, we first need to work out the approximate square meterage of your property.

So to work out the square meterage of your external walls, you simply just need to go outside and measure the length and height of the wall then multiply those two numbers together. This needs to be repeated for each wall you intend to render and then totalled together. This will give you the external wall area.

It’s always good practice to prime the substrate before doing any work. Assuming the substrate is standard masonry, we would recommend that you use our water based primer, which costs approximately 30p per square metre.

Let’s also assume you want to install a Silicone Silicate render system with our standard EPS Basecoat. First we need to calculate how much Silicone Silicate render costs per square metre. One bucket of Silicone Silicate render with a grain size of 1.5mm will cover between 9-10m2, which is roughly £4.90 per square metre. When buying your render remember that coverage will vary based upon the grain size that you go for; the larger the grain size the more product you will have to buy because it will cover less area.

Then we need to take into account the basecoat layer which goes on before the actual coloured render itself to smooth out the external wall and aid adhesion. Using our EPS Basecoat, one bag will cover 4-5m2. Therefore, it will cost £2.40 per m2. The Fibreglass Mesh to be embedded within the basecoat will cost approximately 70p per square metre.

Now we just need to factor in how much primer will be required. With our Silicone Silicate system, you’ll need to use our EWI-333 SiSi render primer which can be tinted to match the colour of the render itself for extra opacity and pigmentation. Generally, we recommend that a large 21kg bucket of render primer will cover approximately 60m2. This means that the primer will come to roughly 80p per square metre.

Finally, we usually find that beading costs around £2 per square metre, although this can vary depending upon the property. 

So totalled all together, the cost of a silicone silicate render system per square metre should be approximately £10.80. Bear in mind that this is an approximation, but if you were to multiply this number with the square meterage of your property then you would get an estimate on how much the materials will cost for installing coloured render on your home!

Which Coloured Render do I Choose?

We have so many coloured renders to choose from, all of which are BBA approved and are the highest quality coloured renders on the market. Our tester pots provide the opportunity for customers to test different colours of render and pick the right one. It’s always best to be able to see the coloured render in person so that you don’t end up unhappy with your decision when it’s applied in full scale on your property.

We offer thin coat and thick coat coloured renders. Our thin coat coloured renders are best sellers; we offer a choice of Silicone, Silicone Silicate, Acrylic and Mineral coloured renders.

  • Silicone render/Silicone Silicate render: Silicone Render is a premium, modern technology coloured render – which is available in hundreds of different colours. Silicone is a very popular choice because it offers hydrophobic properties, which means that it repels water, dirt and organic growth. Silicone render is also super easy to apply because it comes ready to use, so you just apply it straight out the box. (Read more about Silicone Render here).
  • Acrylic render: Acrylic render is very similar to silicone, except for it doesn’t provide the same hydrophobic properties. It’s a solid middle-ground thin coat render because it still provides the same flexibility as other thin coat renders and it’s also great at holding onto colour pigment. (Read more about Acrylic Render here).
  • Mineral render: Mineral render is a dry-mix, thin coat render. This is a very popular choice if you live in a cold or rainy climate because mineral render is extremely fast drying (you can’t apply other renders in cold/rainy temperatures because they take longer to dry). The only thing about this render is that you need to paint it afterwards with silicone paint to seal it in. This is because if it’s left exposed to the elements it can develop lime bloom due to the presence of Portland cement. (read more about Mineral Render here).
  • Monocouche scratch render: Monocouche scratch render is a thick coat, through coloured render. It is more traditional, but does require extra work to install it. This is because the Monocouche needs to be applied in two passes for extra strength and cannot be applied in wet or humid conditions. Monocouche render then needs fibreglass mesh embedded within it to provide extra strength and flexibility (which means it will resist cracking), and then once it’s dried it needs scratching back to achieve the desired texture.

How much does Coloured Render cost to maintain?

Let’s say it’s 10 years down the line and you’re thinking about giving your render a bit of a refresh and a spruce up. Silicone Paint is a great way to do this because it can be tinted to match the exact colour of your existing render. You can read our blog post ‘The Best Masonry Paint? Silicone Paint’ to find out all about why Silicone Paint is so great. However, in terms of giving your render a bit of a refresh, a 15L bucket of Silicone Paint typically covers 60-70m2 so you’re looking at around £3 per m2.

If our monocouche systems are of interest to you, then check out our blog post ‘Monocouche Scratch Render cost per m2’ for a detailed idea of how much you’re looking at with this system.
