EWI-076 Premium Bio Silicone Render

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. 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.

Premium Bio Silicone Render is the most progressive render in the EWI Pro catalogue, offering end-users an advanced range of benefits. What really sets this render apart is its ability to actively break down any sign of organic growth that occurs on the render surface. Premium Bio Silicone offers an enhanced level of impact resistance, especially when used with a fibreglass mesh-reinforced basecoat layer. It also offers increased resistance to UV rays, which means that the coloured render will not fade over time; even the brightest of colours will stay vibrant for years to come! As it is a silicone-based, polymer-modified, thin coat render, Premium Bio is highly breathable and vapour permeable; therefore ideal for Mineral Wool and Wood Fibre systems which also offer breathability. Premium Bio Silicone Render is incredibly flexible, robust and long-lasting - it is the premium choice when it comes to coloured render. Premium Bio Silicone Render is available in thousands of colours and several different textures, allowing you to achieve your desired render finish.

Application

Premium Bio Silicone render comes as a ready-to-use mix and therefore does not need the addition of water. We recommend that you stir the mixture first to ensure that all the colour pigments are evenly distributed throughout. To create an even, textured finish using Premium Bio Silicone render, you will then need to rub up against the surface of the render using circular motions with a plastic render float. You will need to ensure that you have enough people on-site to be able to apply the render to an entire wall at once. If you attempt to apply the render section by section, then you will find that when it dries there will be a scarring effect where the different render sections meet.
