EWI-077 Nano Drex Silicone Render

Nano Drex Silicone Render is EWI Pro’s most advanced thin-coat Silicone Render. It offers unmatched performance in terms of flexibility, breathability and self-cleaning properties. Formulated using nano-silicone technology, this render is completely hydrophobic, presenting unbeatable water and dirt repellence. It also offers the best protection against unwanted biological growth.

Rather than settling on the surface and creating damp and mould, any water that comes into contact with this render will form droplets. The droplets are then repelled from the surface, making this products ideal for use in areas that are highly exposed to organic matter.

Nano Drex is available in thousands of colours and several different textures, allowing you to achieve your desired render finish.

Please note: All tinted renders are made to order, so we do not accept any returns on tinted products. Renders that have not been tinted can be returned as per our normal T&Cs.

On receipt of your tinted render, please ensure the colour is as expected before application. We recommend buying one of our render samples before purchasing to ensure you are 100% happy with your chosen colour.

Colours from different batches may vary slightly. To avoid inconsistencies, mix tubs before application.


Nano Drex Silicone Render is a ready-to-use render, so it can be used straight out of the bucket and does not need to be mixed with water. However, we recommend mixing the render before use to ensure an even distribution of the colour pigments. Always check that the colour of the render matches your order before application.

To apply Nano Drex Silicone Render, use a trowel for initial application onto the substrate, then a plastic float to create the desired texture. Remember that this is a thin-coat silicone render system, so the thickness of the render should match the selected grain size of the render.

Silicone Render Storage

Our render comes ready to use in a 25kg plastic tub. Store in a cool, dry place away from direct sunlight and mix regularly. For best results, use within 12 months of the production date (as printed on the bucket).

  1. Keith Fryer

    Wanted to wait and see if this product performed as advertised. Applied the nano drex silicone render in September 2019 and it still looks like it was applied yesterday. Really happy with the finish, made a massive improvement to the look of our house. Thanks Keith

    • Alana

      That’s great to hear!

  2. Ian Picton

    House was looking a bit tired so used the EWi pro nano render system. Looks great. (1mm, pure white)

    • Alana

      1mm is a lovely smooth look, isn’t it! I hope you are still loving it, Nano drex render really can give your home a complete makeover 🙂

  3. Claire76

    Incredible product – our house is now the envy of all our neighbours. Went for 27570 (Clay) in the 1.5mm grain. It honestly looks amazing, really nice and modern and clean.

    • Alana

      I’m glad to hear you liked it!

    Applied to the house and it has made an incredible difference. Brought our pebbledash property bang up to date. Expensive but defo worth it.

  6. Ashley Hills

    Applied to pebbledash and it really modernised the look and feel of our house. As advised on the phone to the store’s technical team, application is a proper trade and so we found someone with experience in applying silicone renders. Would recommend.
