EWI-040 Silicone Silicate Render is breathable, flexible, hydrophobic and self-cleaning. It is available in hundreds of different colours. Render colours may appear different on-screen compared to real life, we therefore always recommend that you order a colour sample before making a final decision.

About Silicone Silicate Render

EWI-040 Silicone Silicate Render is our most popular coloured through top coat. The render is breathable, flexible, hydrophobic and self-cleaning. Although this silicone silicate render is often used as the final stage of EWI Pro external wall insulation systems, it can be used as a standalone top coat render, provided the reinforcement layer is used too – it is available in hundreds of different colours.

  • Water repelling
  • Frost-proof
  • High elasticity
  • High vapour permeability
  • Resistant to UV rays
  • Available in 4 different grain sizes

The product is a decorative, ready-to-use silicone silicate thin-coat render. EWI-040 Silicone Silicate render is available in either 1.0mm, 1.5mm, 2.0mm and 3.0mm grain sizes and is available in 100’s of different colours.

The through colour silicone silicate render is suitable for interior or exterior surfaces, but works best when applied on top of a reinforcement layer as part of the whole thin-coat render or insulation system.

The silicone silicate render not only provides a decorative finish, it also provides a strong protective coating to the property, helping protect the underlying brickwork. Silicone silicate render is also breathable, so can be used in conjunction with mineral wool EWI systems.

Applying Silicone Silicate Render

As mentioned, the silicone silicate render is ready to go out of the bucket, but we do recommend giving it a mix prior to use, especially if a colour has been chosen, to ensure an even distribution of the pigments (always check the colour of the render matches your order prior to application)

Apply the render to the substrate using a trowel and then use a plastic float to generate the required texture. Remember this is a thin coat render system, so the thickness of the render layer should match the grain size of the render chosen.

Silicone Silicate Render Application Conditions

  • Substrate primers: EWI-333 Silicone Silicate Primer should be applied on top of the EWI-220 Basecoat prior to applying the decorative render finish.
  • Application and setting temperature (air, substrate, materials): from +5°C to +25°C.
  • Grain size distribution: 1mm, 1.5mm, 2mm and 3 mm.

Caution! In case of wall thermal insulation systems, when plastering facades with a large area, it is recommended that colours with brightness coefficient (dispersed reflection) of at least 25% should be used. These coefficients are shown in the colour pallet of EWI Pro Insulation Systems plasters and paints.

Coverage rates of Silicone Silicate Render

  • 1.0mm – 1.9kg/m2 therefore a bucket should cover 12 – 13 m2
  • 1.5mm – 2.4kg/m2 therefore a bucket should cover 9 – 10 m2
  • 2.0mm – 3.4kg/m2 therefore a bucket should cover 7 – 8 m2
  • 3.0mm – 5.0kg/m2 therefore a bucket should cover 5 – 6 m2

Technical Specifications

  • Composition: potassium water glass, silicon emulsions, fillers, modifying admixtures, pigments
  • Bulk density: approx. 1.84 g/cm3
  • Relative diffusion resistance (non-trowelled 3 mm thick layer): ≤ 0.13 m
  • Water absorption after 10 hours: ≤ 360 g/m²
  • Colours: a range of 35 standard colour tints are available through the website, with 100s more available in our stores. The standard colour of the render is white. Colours are tinted on instruction from the order reference.

  1. Rated 5 out of 5

    Silicone Silicate render is far superior to acrylic and mineral render. Been using it for over 1 year now and goes on in one go unlike mineral and is far better at standing up to bad weather. 1mm texture seems to be customers choice. Delivered on time. Will buy again. 

  2. Rated 5 out of 5

    We have used loads of different insulated render systems and this based on value is right up there with the best of them. We received our COLOURED render the next day! Normally we are waiting for 4-5  days for coloured render delivery. Def order again and recommend to others.

  3. Rated 5 out of 5

    Easy to use coloured render. Delivery from EWISTORE was next day. Would recommend to anyone looking to buy render.

      Thanks Chris, glad you were happy with it!

    I had a renovation on one of my rural properties late last year. Having gone through the expensive process of hiring a top architectural company off Berkley Square, they had missed the fact that I could install this product on top of insulation. My builder Mat Szkola who is very reasonable on price suggested I look at EWI Pro Insulation with this textured render. Having Mat with me and talking to EWI Store team, they to my shock confirmed I had wasted good money on bad advice and in the end I am so pleased I didnt go for cavity wall retrofit. 

    The render with insulation has been installed and I am pleased with it. Now to wait for another winter to see how it impacts my bills.

      No problem – I am glad we could help. It  is very interesting that many architectural firms aren’t clued up on solid wall insulation as it is a fantastic solution offering incredible energy savings and producing an attractive, clean finish to properties.

    If you are looking to buy render, but it from EWIStore. The render is high quality and perhaps more importantly we can get colour render delivered next day (the EWIpro render). Would strongly recommend!

    Thanks for the fantastic deal on two tubs of render. Average consumption for me was about 9 per metre in square. Have a few left over which i want to do on immediate job.

  7. Rated 5 out of 5

    Had used K-Rend previously but tried this on a recommendation. It goes on very easily and looks great once the plastic float has gone on it. Far better value render than k-rend so will definitely use going forward.

    Top gear this.

  9. Rated 4 out of 5

    Good trade discount on product. Goes on well and doesnt drag when floating it.

  10. Rated 4 out of 5

    The final finish looks good but i managed to only get 8m2 per bucket so had to order 2 extra buckets to finish the job
