EWI Pro Silicone Silicate Render is our most popular top coat. The render is breathable and hydrophobic meaning it will self-clean and is water repelling. Silicone Silicate render can be mixed in hundreds of colours. Available in 4 different grain sizes – 1mm, 1.5mm, 2mm and 3mm.

  • Waterproof
  • Frost-proof
  • High elasticity
  • High vapour permeability
  • Resistant to UV rays

EWI-040 Silicone Silicate Render is one of the most popular products in the EWI Pro catalogue. The render forms a long lasting, aesthetically-pleasing protective barrier on your external walls. Although this 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.

Technical Details

Ready-to-use silicone silicate render. Does not contain ammonia or organic solvents. It is highly breathable, has great adhesive and elastic properties and also is durable, with excellent colour stability. EWI-040 Silicone Silicate render also has very high resistance to weather conditions and contamination, as it is hydrophobic.

Coverage is as follows:

  • 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

  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.

    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.
