EWI-076 Premium Bio Silicone Render is the most advanced, high quality render in the EWI Pro catalogue.

About Premium Bio Silicone Render

EWI-076 Premium Bio Silicone Render is the most progressive render in the EWI Pro catalogue, offering end-users with an advanced range of advantages and 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.

It is also available in hundreds of different colours, so every design preference can be catered for.

  • Weatherproof
  • Advanced resistance to algae and plant growth
  • Frost-proof
  • Hydrophobic
  • Vapour-permeable
  • Self-cleaning
  • UV protection
  • Impact resistance

EWI-076 Premium Bio Silicone Render is a ready-to-use render suitable for use on brick, concrete, traditional plasters, gypsum substrates and chipboard. The render is a mixture of silicone and acrylic resins, with mineral fillers and pigments.

This product does not contain ammonia or organic solvents.

It is suitable for interior and exterior surfaces.


Premium Bio Silicone render comes as a ready-to-use mix so you don’t need to add anything to it before use. It is advisable that you stir the mixture first to ensure that all the colour pigments are evenly distributed throughout.

To create an even, textured finish you will then need to rub up the surface of the 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.
