Envirograf Intumescent Acrylic and Acoustic Mastic – White 310 ml (SKU: AM_White)
Reliable Fire-Resistant and Acoustic Sealant for Various Applications
The Envirograf Intumescent Acrylic and Acoustic Mastic in White (310 ml) is a highly effective sealant designed for fire-stopping and acoustic insulation. Here are the key features and usage details:
- Fire Resistance:
- This intumescent mastic expands up to five times its volume when exposed to fire, providing a robust barrier against fire, smoke, and toxic fumes.
- Versatile Application:
- The mastic is suitable for sealing gaps from 1mm to 30mm wide, making it ideal for use around exit door frames, cable trays, ducting, and partitions. It works effectively both horizontally and vertically.
- Environmentally Friendly and Flexible:
- The halon-free formulation ensures environmental safety. After application, the mastic forms a paintable skin while remaining permanently flexible, allowing for long-lasting performance.
- Ideal for Multiple Sealing Needs:
- Use it to seal between door frames and walls, around partition edges, or in voids around services like pipes. It can be used in conjunction with Envirograf Intumescent Slabs, Blocks, and Expansion Joints for enhanced fire-stopping.
- Paintable Finish:
- Once the surface skin forms, you can paint over the mastic to match your decor.
- Easy Application:
- The standard 310 ml tube fits any normal skeleton gun, ensuring straightforward application. For best results, apply the mastic to a minimum depth of 12mm around ceiling, floor, and wall joints, especially in areas where Halon gas could escape.
- Surface Preparation:
- Ensure all surfaces are clean and sound before application. Wipe oily surfaces with white spirit and allow them to dry. Moisten dry, dusty brickwork to improve adhesion before applying the mastic.
This product provides a reliable, flexible, and fire-resistant solution for sealing gaps in various construction and maintenance projects.
