Presenting the EWI-075 Silicone Render, a high-performance thin-coat solution engineered for external building facades. This polymer-modified, ready-to-use render system delivers a decorative finish specifically formulated for external application. The product demonstrates excellent adhesion to diverse substrates including brick, concrete, render carrier boards, traditional plaster finishes, gypsum bases, and external wall insulation assemblies.

The EWI-075 Silicone Render excels in breathability performance, making it the ideal choice for pairing with breathable insulation materials used in external wall insulation schemes. Whether specifying Mineral Wool or Wood Fibre insulation, this render maintains optimal vapour permeability throughout your system.

This silicone-based render offers versatility for both standalone render-only applications and integrated insulation systems. Compared to thicker alternatives such as sand-cement or monocouche renders, the EWI-075 delivers superior durability and crack resistance, ensuring a long-lasting decorative surface finish.

Availability

1. The EWI-075 Silicone Render is supplied across an extensive colour palette to suit diverse aesthetic requirements, encompassing standard RAL and NCS colour specifications.
2. Multiple grain size options are available, ranging from 0.5mm through to 3mm, enabling customisation of surface texture characteristics. A 0.5mm grain delivers a refined, smooth finish, whereas a 3mm grain creates pronounced texture with enhanced visual depth and architectural interest.

Application

EWI-075 Silicone Render is supplied as a ready-to-use product requiring no water addition. Application is straightforward—simply dispense directly from the container. 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, commence with an initial trowel pass to establish substrate coverage, then utilise a plastic float to create the desired textured finish. As a thin-coat system, application thickness must correspond precisely to the specified grain size.

Application Specifics

When installing EWI-075 Silicone thin coat Render on building elevations, sufficient applicators must be deployed to complete entire wall sections without interruption. This is critical because the render cures rapidly, particularly during warm weather conditions. Achieving consistent appearance requires swift application and finishing techniques. Attempting to render isolated sections will produce visible demarcation lines where application phases meet across the completed elevation.
