• Polymer-Modified: The polymer modification improves adhesion, flexibility, and workability, making it easier to apply and enhancing the long-term performance of the adhesive.
• Extended Open Time: The extended open time allows more time for adjustment during installation, ensuring precise placement and alignment of insulation boards.
• Versatile: Suitable for use with various types of thermal insulation boards, including extruded or expanded polystyrene, mineral wool, polyurethane, and cork.
• High Bond Strength: Provides strong adhesion to concrete, render, and masonry substrates, ensuring the insulation boards remain securely fixed to the surface.
• Reinforced System: When combined with fiberglass mesh, it provides an ideal foundation for the subsequent render layer, creating a seamless, durable surface.
• Weather Resistance: The adhesive is highly resistant to environmental stressors, ensuring the system remains stable under various weather conditions.

Certifications:

• EN 998-1: Certified according to this standard for rendering mortars, ensuring it meets high quality and performance requirements.
• EN 12004: Classified as C2 E adhesive, confirming its high bonding strength and extended open time.
• CE Marked: The product complies with EU health, safety, and environmental standards, ensuring it is safe and effective for use.

Applications:

1. Insulation Board Adhesion: Ideal for fixing thermal insulation boards made of extruded or expanded polystyrene, mineral wool, polyurethane, and cork to concrete, masonry, or render facades.
2. External Thermal Insulation Systems (ETICS): When reinforced with fiberglass mesh, it serves as an ideal adhesive for the exterior of thermal insulation systems, providing a durable base for subsequent rendering or finishing layers.
3. Facade Insulation: Perfect for insulating building facades, enhancing thermal efficiency and reducing energy consumption in both residential and commercial properties.
4. Fixing Insulation to Various Substrates: Suitable for use on a variety of substrates, including concrete, masonry, and render, ensuring a reliable bond even on challenging surfaces.

Advantages:

• Superior Bonding: Provides strong and lasting adhesion to thermal insulation materials, ensuring the insulation boards remain secure over time.
• Flexibility: The fiber-reinforced and polymer-modified nature ensures the adhesive remains flexible, reducing the risk of cracking due to substrate movement or temperature fluctuations.
• Weather Resistance: Designed for exterior use, it performs well under changing weather conditions, providing stability to the insulation system.
• Ideal for ETICS: When used with fiberglass mesh, this adhesive forms an ideal base for the render layer, creating a durable, weather-resistant surface.

Application Instructions:

1. Surface Preparation: Ensure the substrate (such as concrete, render, or masonry) is clean, dry, and free from any dust, dirt, or contaminants that could affect adhesion.
2. Mixing: Mix the adhesive with water according to the manufacturer’s instructions to achieve the proper consistency. The product should have a workable, spreadable texture.
3. Application: Apply the adhesive to the back of the insulation boards using a notched trowel, ensuring a uniform coverage. Press the boards firmly onto the prepared surface.
4. Reinforcement with Mesh: If required, apply fiberglass mesh to the surface of the fixed insulation boards, ensuring it is well-embedded into the adhesive layer.
5. Subsequent Layers: After the adhesive has set, the boards can be finished with the render coat or other finishing materials, ensuring a smooth, durable surface.

Ideal For:

• External Thermal Insulation Systems (ETICS): Perfect for use in combination with insulation boards and fiberglass mesh to create a durable, energy-efficient thermal insulation system for external walls.
• Facade Insulation: Ideal for improving the thermal performance of building facades while providing excellent adhesion and flexibility for the insulation boards.
• High-Performance Applications: Suitable for use in both residential and commercial properties, ensuring a long-lasting and weather-resistant insulation system.

This fiber-reinforced, polymer-modified cement-based adhesive offers a robust, flexible solution for fixing thermal insulation boards and forms a reliable base for further coatings and finishes. Its high strength and adaptability make it an excellent choice for external insulation systems, ensuring durability and performance under varying environmental conditions.
