Presenting EWI-075 Silicone Render, a high-performance thin-coat solution for external facades. This polymer-modified, ready-to-use render is engineered for external application, providing a durable decorative finish. It demonstrates excellent adhesion to multiple substrates including brick, concrete, render carrier boards, traditional plasters, gypsum bases, and external wall insulation systems.

The EWI Pro Silicone Render formulation features superior breathability, making it ideal for pairing with breathable insulants in external wall insulation applications. Whether combined with Mineral Wool or Wood Fibre insulation, this render maintains the vapour permeability essential for system performance.

The Silicone Render offers flexibility for standalone render-only applications without insulation layers. Compared to thicker alternatives such as sand and cement or monocouche systems, this thin-coat silicone formulation resists cracking and delivers extended durability with minimal maintenance.

Availability

1. EWI-075 Silicone Render is supplied across an extensive colour palette, encompassing standard RAL and NCS options to match your specification.
2. Multiple grain sizes are available—0.5mm, 1mm, 1.5mm, 2mm, and 3mm—allowing you to select the finish texture required. A 0.5mm grain produces a smooth, refined appearance, whilst a 3mm grain creates pronounced texture and visual depth on your building facade.

Application

EWI Pro Silicone Render is supplied as a ready-to-use product requiring no water addition. Apply directly from the container without further preparation. Prior to use, stir thoroughly to ensure uniform pigment distribution throughout the batch. Always confirm colour accuracy against your order documentation before commencing application.

To apply EWI-075 Silicone Render, use a trowel for initial substrate application, then employ a plastic float to establish the desired surface texture. As a thin-coat system, application thickness must correspond precisely to your selected grain size specification.

Application Specifics

When installing EWI Pro Silicone thin coat Render on building elevations, ensure sufficient applicators are deployed to complete each elevation without interruption. Rapid setting occurs, particularly during warm weather conditions. Achieving consistent finish requires continuous working and swift rubbing-up of the render surface. Partial elevation rendering will produce visible joint marks where sections meet upon completion of the full elevation.
