The substrate must be clean, dry and dust free. It then needs to be primed using the Water Based Primer, which will help reduce the absorptive capacity of the substrate.
Starter Track & Clip-on Profile
The starter track is attached to the substrate above the DPC. This provides a level surface for the insulation to sit on; it also protects the base of the insulation against damp.
The insulation is fixed to the substrate using the EWI-225 Premium Basecoat. This is the strongest basecoat-adhesive in the EWI Pro catalogue, offering a long-lasting and secure adhesion. The adhesive is applied to the back of the insulation boards which are then secured to the wall.
Kingspan K5 Insulation
Kingspan K5 insulation easily upgrades the thermal properties of the building, ensuring a reduction in thermal transfer. Kingspan K5 is a premium insulation board and is an ideal solution for when space is limited.
Mechanical fixings are used as a secondary method of securing the insulation to the substrate. Metal fixings should be used for Kingspan K5 insulation.
The basecoat reinforcement layer is applied to the surface of the insulation boards and consists of the EWI-220 Adhesive or the EWI-225 Premium Adhesive. The reinforcement layer creates a smooth surface before applying the render.
Fibreglass reinforcing mesh is embedded within the basecoat adhesive to enhance the tensile strength and crack resistance of the render system.
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.
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.
