Substrate Preparation
The substrate must be clean, dry and dust free.
Parge Coat
A parge coat must be applied to the substrate to prime and level the surface. The EWI-269 Lightweight Basecoat can be applied up to 10mm thick to create a parge coat.
Basecoat
The basecoat reinforcement layer is applied to the insulation boards and consists of the EWI-225 Premium Adhesive. The reinforcement layer creates a smooth surface before applying the render.
Fibreglass Mesh
Fibreglass reinforcing mesh is embedded within the basecoat adhesive to enhance the tensile strength and crack resistance of the render system.
Render Primer
The render primer is painted onto the reinforcement layer to ensure that the render adheres to the basecoat, and to contribute towards a durable render finish.
Decorative Finish
EWI Pro offer a range of coloured renders, all of which can enhance the external appearance of the property. Each render provides a long-lasting, crack-proof finish and come with a range of advantages for the building structure. We recommend choosing a breathable render for use with Wood Fibre insulation.

Structural Insulated Panels (SIPs)
Render Only
SIPs Panels consist of an insulating foam core sandwiched between two render carrier boards. SIPs are extremely strong, energy-efficient, and cost-effective, especially when paired with our Premium Basecoat, and finished off using a decorative and breathable thin coat render system.
