EWI-075 Silicone Render is a polymer modified, 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.

Application

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.
