EWI Pro Silicone Render is one of our most popular Silicone Render products. This render is a polymer modified, ready-to-use render that normally gets 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 breathable, and therefore ideal for application onto external wall insulation systems where a breathable insulant is being used, such as Mineral Wool or Wood Fibre insulation.
The Render is also flexible, so it can be applied as part of a render-only system (i.e. no insulation) and will provide a robust, long-lasting decorative finish that is unlikely to crack compared to thicker sand and cement or monocouche renders.
EWI Pro Silicone Render is available in thousands of different colours (e.g. RAL or NCS colours), so if the colour you are looking for is not displayed above then please call us on 0203 3974067.
The Silicone Render is also available in different grain sizes, 0.5mm, 1mm, 1.5mm, 2mm and 3mm, giving a range of different finishes. The 0.5mm grain will give your property a smoother look whereas going for our 3mm grain will give a more textured look.
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.
EWI Pro Silicone Render is a ready-to-use render. This means it can be used straight out of the bucket and no water needs to be mixed in. 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 Pro 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.
Silicone Render comes in a 25kg bucket and is ready for application. We do suggest however giving the bucket a mix with a paddle mix just to ensure any colour pigments are evenly distributed.
The Silicone Render is applied on to the basecoat in a very thin layer – the grain size of the render should match 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 basecoat layer is approximately 4-7mm (depending on the basecoat being used) so the total basecoat + render should be approximately 8mm thick in total.
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 is important because the render can go off very quickly (during the summer months) so it needs to be rubbed up quickly to achieve the correct consistent finish. 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.
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).
