EWI-077 Nano Drex Silicone Render

Nano Drex Silicone Render is a highly hydrophobic thin coat render. The Nano Drex Silicone Render is a premium thin coat render within the EWI Pro catalogue, designed to be used as the finishing coat in the external wall insulation system, or as part of a render-only system.

Nano Drex Silicone Render is formulated with nano-silicone technology, which means that it is completely hydrophobic. Upon contact with the render, water will form droplets that are completely repelled from its surface; this limits the amount of dirt and organic matter than can settle on the surface of the render. Its advanced self-cleaning capabilities make Nano Drex Silicone ideal for areas that are highly exposed to organic matter.


Nano Drex Silicone Render is a ready-mix render, so it can be used straight out of the bucket and does not require mixing with water. However, we do recommend giving the render a mix prior to use to ensure an even distribution of the colour pigments. Before application, always check that 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 that this is a thin coat render system, so the thickness of the render layer should match the grain size of the render chosen.

Application Conditions

  • Intended for application onto an EWI Pro specified basecoat
  • Substrate primers: EWI-301 Water Based Primer
  • Basecoat primers: EWI-333 SiSi Render Primer
  • 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 the case of external wall insulation systems, when rendering facades with a large area, it is recommended that colours with a brightness coefficient (dispersed reflection) of at least 25% should be used. These coefficients are shown in the colour pallet of EWI Pro Insulation Systems renders and paints.

Coverage Rates

  • 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

Storage Conditions

Comes ready-to-use in a 25kg plastic tub.

Store in a cool, dry place. Shelf life: up to 12 months from the date of manufacture. Please note: In order to tint the product we break the seal. We therefore do not accept returns on tinted items. Store in a cool, dry place away from direct sunlight and mix regularly. Colours from different batches may vary, to avoid inconsistencies mix tubs together prior to application.
