EuroFix Thermo Coat — Base Coat Render
Fibre-reinforced base coat that embeds the reinforcing mesh
Description
EuroFix Thermo Coat is a flexible, fibre-reinforced cement render applied over insulation boards to embed the fibreglass mesh and form the tough, crack- and impact-resistant reinforcement layer of an ETICS façade. It levels the boards and provides a weatherproof base for the decorative finish render.
Fields of Application
- Reinforcement base coat over EPS / XPS boards
- Embedding the fibreglass reinforcing mesh
- Levelling and protecting the insulation layer
- Base for textured / decorative finish renders
Technical Properties
| Property | Value |
|---|---|
| Adhesion to EPS | ≥ 0.08 N/mm² (EPS failure) |
| Layer thickness | 3–5 mm (mesh embedded) |
| Application temperature | +5°C to +30°C |
| Crack resistance | Fibre-reinforced, flexible |
Surface Preparation
- Insulation boards must be firmly bonded, anchored, flush and dust-free.
- Allow the board adhesive (Thermo Fix) to cure before coating.
Application Method
- Mix 25 kg with ≈ 5–5.5 L clean water to a smooth, workable paste.
- Trowel a first layer onto the boards and embed the mesh into the wet coat with 10 cm overlaps.
- Apply a thin second layer to fully cover the mesh and smooth flat.
- Allow 24–48 h to dry before the finish render.
Consumption
| Use | Rate |
|---|---|
| Base coat with mesh | ≈ 4–5 kg/m² |
Comparison vs. Ordinary Site Mix
| Criterion | Ordinary Mix | EuroFix |
|---|---|---|
| Crack resistance | Cracks over boards | Fibre-reinforced, flexible |
| Mesh embedding | Poor, mesh exposed | Full, even cover |
| Weather resistance | Low | High, system-tested |
Consumption & Cost
The base coat is what keeps an insulated façade from cracking. A plain sand-cement render over polystyrene will craze and let water in within a season. EuroFix Thermo Coat's fibre reinforcement and flexibility hold the system together, protecting the insulation and the finish for the long term.
