Envirograf Intumescent Acrylic and Acoustic Mastic – Brown 310 ml (SKU: AM_Brown)
High-Performance Fire-Resistant and Acoustic Sealant
The Envirograf Intumescent Acrylic and Acoustic Mastic in Brown (310 ml) is engineered for superior fire-stopping and acoustic sealing. Here’s why it stands out:
- Fire Resistance
- This mastic expands up to five times its original volume during a fire, creating a strong barrier against flames, smoke, and toxic fumes. It effectively prevents fire from spreading through gaps and voids.
- Versatile Application
- You can use this mastic for sealing gaps from 1mm to 30mm wide. It works well around exit door frames, cable trays, ducting, and partitions. Suitable for both horizontal and vertical applications, it offers great flexibility.
- Environmentally Friendly and Flexible
- The halon-free formula ensures environmental safety. After application, the mastic forms a skin that you can paint over, while the material remains flexible for lasting protection.
- Multiple Sealing Uses
- This mastic is perfect for sealing gaps between door frames and walls, around partition edges, or in voids around services like pipes. It pairs well with Envirograf Intumescent Slabs, Blocks, and Expansion Joints for enhanced fire resistance.
- Easy Application and Preparation
- The 310 ml tube fits any standard skeleton gun, making application straightforward. To prepare surfaces, clean them thoroughly. If surfaces are oily, wipe them with white spirit and dry. Moisten dry, dusty brickwork before applying the mastic to improve adhesion.
- Paintable Finish
- Once the surface skin forms, you can paint over the mastic, making it adaptable to different decor styles while maintaining its functionality.
This product offers a reliable and flexible solution for a wide range of fire-stopping and sealing needs in construction and maintenance projects.
