Envirograf Intumescent Acrylic and Acoustic Mastic – Grey 310 ml
Versatile Fire-Resistant Sealant for Comprehensive Protection
The Envirograf Intumescent Acrylic and Acoustic Mastic (SKU: AM_Grey) in Grey (310 ml) offers effective fire-resistant sealing for various applications. Here’s why this product stands out:
- Fire Resistance:
- This mastic expands up to five times its volume when exposed to fire, creating a strong barrier against flames, smoke, and toxic fumes.
- Multiple Uses:
- Use it to seal gaps from 1mm to 30mm wide, both horizontally and vertically, around door frames, cable trays, ducting, and partitions. Additionally, you can pair it with other Envirograf products like intumescent slabs and blocks.
- Acoustic and Environmentally Friendly:
- Besides its fire resistance, this mastic also reduces noise transmission. It’s halon-free, making it safer for the environment, and it adheres well to various materials, forming a lasting, flexible seal.
- Post-Application Flexibility:
- After application, a skin forms that can be painted over. Despite this, the mastic remains flexible, ensuring long-term performance.
- User-Friendly Application:
- The 310 ml tube fits standard skeleton guns, making it easy to apply. For best results, ensure a minimum depth of 12mm, especially in areas like computer rooms to prevent Halon gas escape.
- Simple Preparation:
- Clean all surfaces thoroughly before application. If surfaces are oily, wipe them with white spirit and dry them. For dry, dusty brickwork, moisten the area to improve adhesion.
This mastic provides a reliable, flexible, and fire-resistant solution for various construction and maintenance tasks.
