Our EWI-075 Silicone Render is a high-performance, ready-to-use coating engineered for external applications. This polymer-modified render delivers a decorative finish whilst maintaining excellent adhesion to brick, concrete, render carrier boards, traditional plasters, gypsum substrates, and external wall insulation systems.

The EWI-075 Silicone Render excels in breathability, making it an ideal choice for use with breathable insulants in external wall insulation applications. When paired with Mineral Wool or Wood Fibre insulation, this render preserves the vapour permeability essential for system performance.

This silicone-based render offers superior flexibility and can be applied as a standalone finish without insulation backing. Compared to thicker alternatives such as sand and cement or monocouche systems, the EWI-075 provides exceptional durability with minimal cracking risk, ensuring a long-lasting protective and aesthetic layer.

Availability

1. The EWI-075 Silicone Render is supplied across an extensive colour palette, encompassing standard RAL and NCS colour options to suit diverse architectural requirements.
2. Multiple grain size options are available, ranging from 0.5mm through to 3mm, allowing you to tailor the surface texture to your specification. A 0.5mm grain delivers a refined, smooth finish, whilst a 3mm grain creates a pronounced textured appearance with enhanced visual depth and character.

Application

EWI-075 Silicone Render is supplied as a ready-to-use product requiring no additional water. Application is straightforward—simply dispense directly from the bucket. Prior to use, thorough mixing is recommended to ensure uniform pigment distribution. Always confirm colour accuracy against your specification before commencing application.

To apply the EWI-075 Silicone Render, begin with an initial trowel pass onto the prepared substrate, then use a plastic float to establish the desired texture finish. As this is a thin-coat silicone system, application thickness must correspond to the selected grain size.

Application Specifics

When installing EWI-075 Silicone thin coat Render on building elevations, ensure sufficient applicators are present to complete entire elevations in a single operation. This is critical because the render cures rapidly, especially during warm weather conditions. Maintaining consistent application speed and technique is essential for uniform appearance. Partial elevation work will result in visible joints where render sections meet upon completion of the full elevation.
