Here at EWI Store, we offer a vast range of coloured renders to both improve the look of your home and cater to every taste. Our renders can be tinted or matched to absolutely any colour, including any NCS, RAL and Pantone colour, allowing for maximum colour customisation. What’s more, with their advanced breathable, flexible and self-cleaning properties, rest assured our renders will offer your property the utmost protection.

Choosing a coloured render for your property can be overwhelming. That’s why we offer colour charts and render tester pots to assist you in deciding which colour is best for you before making a purchase. However, once you’ve made the all-important decision as to which colour you’d like, you’re probably wondering: how much will it cost? Well, wonder no more, as we’re here to help!

Calculating the cost of coloured render per square metre

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

Working out the square meterage of your external walls is easy: you just need to go outside and measure the length and height of the wall, then multiply the two numbers together. This needs to be repeated for each wall you intend to render, then totalled all together; this total will give you the external wall area.

Priming the substrate

Assuming the substrate is standard masonry, we recommend that you use our Water Based Primer, which costs around 30p per square metre.

Applying the Basecoat and Mesh

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

Using a Render Primer

Now, we need to consider how much render primer your property will require. For a Silicone Silicate system, you’ll need our EWI-333 Render Primer, which can also be tinted to match the colour of the render for extra opacity and pigmentation.

A large 21kg bucket of Render Primer will cover approximately 60m². This means that the primer will come to roughly 80p per square metre.

Choosing a render

Let’s assume you want to go for a Silicone Silicate Render. First, we need to calculate how much Silicone Silicate Render costs per square metre.

For instance, one bucket of Silicone Silicate Render – with a grain size of 1.5mm – will cover between 9 and 10m², which is roughly £4.90 per square metre.

When buying your render, remember that coverage will vary based on the grain size that you go for; the larger the grain size, the more product you will need because it will provide less area coverage.

Beading per m²

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

The total cost of Silicone Silicate coloured render system per square metre

Altogether, the cost of a Silicone Silicate Render system per square metre approximately come to £10.80. Bear in mind that this is an approximation. Nonetheless, if you were to multiply this number with the square meterage of your property, you should get an idea as to how much the materials will cost for installing coloured render on your home!

Which coloured render do I choose?

We have a huge range of coloured renders to choose from, all of which are BBA-approved and of the highest quality on the market.

We also provide tester pots that allow you to test different colours. It’s always best to see the coloured render in-person to ensure that you are happy with your decision before it’s applied all over your property.

Our thin-coat-coloured renders are bestsellers. We offer:

• Silicone Render/Silicone Silicate Render: Silicone Render is a premium, modern-technology coloured render which is available in hundreds of different colours. It is a customer favourite as it offers hydrophobic properties, meaning that it repels water, dirt and organic growth. Silicone Render is also ready-to-use, making it super easy to apply; it can be applied straight out of the box! Read more about Silicone Render here.
• Acrylic Render: Acrylic Render is very similar to Silicone Render, except it doesn’t provide the same hydrophobic properties. Saying that, it still provides the same flexibility as other thin-coat renders and is great at holding onto the colour pigment; it’s a solid middle-ground thin-coat render. 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 or wet conditions as they take longer to dry). However, this render needs to be painted afterwards with silicone paint to seal it in because, if it’s left exposed to the elements, it can develop lime bloom due to its inclusion of Portland cement.

How much does Coloured Render cost to maintain?

Let’s say, 10 years down the line, you want to give your render a bit of a refresh; Silicone Paint is a great way to do this as it can be matched to the exact colour of your existing render. To learn more about why Silicone Paint is best for refreshing an existing polymer-modified render, you can read this blog. However, in terms of sprucing up your render, a 15l bucket of Silicone Paint typically covers 60 to 70m². Therefore, you’re looking at around £3 per m².
