EWI-075 Silicone Render

EWI-075 Silicone Render is one of our most popular Silicone Render products. This polymer modified, ready-to-use render is normally applied externally to produce a decorative finish on buildings. The render is suitable for use on brick, concrete, render carrier boards, traditional plasters, gypsum substrates and on external wall insulation systems.

EWI Pro Silicone Render is highly breathable. This makes it ideal for application on external wall insulation systems where breathable insulants have been used. For example, Mineral Wool or Wood Fibre insulation.

The Render is also flexible, meaning you can apply it as part of a render-only system (i.e. no insulation). Unlike thicker sand and cement or monocouche renders, our Silicone Render provides a robust, long-lasting decorative finish that is unlikely to crack over time.

You can achieve a range of finishes from the following render grain sizes: 1mm, 1.5mm, 2mm and 3mm. The 1mm grain will give your property a smoother look whereas going for our 3mm grain will give a more textured look.

Please note: We do not accept returns on tinted products because our tinted renders are made-to-order. 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 an uneven finish, mix tubs before application.


EWI Pro Silicone Render is a ready-to-use render. This means that no water is needed and you can use it straight out of the bucket. 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 EWI-075 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.

The Silicone Render is not applied directly on to a substrate (e.g. brick) – instead, it must sit on a EWI Pro Basecoat layer (e.g. EWI Pro Premium Basecoat EWI-225) with embedded mesh.

Our Silicone Render comes in a 25kg bucket and is ready for immediate application. However, before application, we recommend that you mix the bucket with a paddle mix. This ensures that colour pigments are evenly distributed.

You can then apply a very thin layer of Silicone Render to the basecoat. You should ensure the grain size of the render matches the thickness of the render layer. For example, if you decided to install 1.5mm Silicone Render, then that layer should be just 1.5mm thick. The total thickness of the basecoat and render should be approximately 8mm as the basecoat layer is around 4-7mm (depending on the selected basecoat).

Application Specifics

When installing EWI Pro Silicone Render on a building, it is important to ensure there are enough applicators on-site to be able to apply the render to one entire elevation. This step is important because the render can go off very quickly (especially during summer months). To achieve a consistent finish, you can rub up the render quickly. Likewise, if you try and render just a small area of one elevation, then when you try to finish this elevation there will be scarring where the render sections meet.

Silicone Render Storage

EWI Pro Silicone Render comes ready to use in a 25kg plastic tub. Store in a cool, dry place away from direct sunlight and mix regularly. EWI Pro Silicone Render should be used within 1 year of the production date (as printed on the bucket).
