Uses
The Pyro Mate by Everbuild is the perfect choice of sealant when requiring a high-strength, high-performance product which provides excellent fire resistance and acoustic sound-deadening properties. Everbuild technicians crafted this product with a neutral cure and elastic silicone to resist fire while still being flexible. Application that this product is typically applied to include;
- All building joints that require a fire-rating sealant
- Sealing voids, joints and irregular holes in fire walls, partitions and other structures
- Fire-rated expansion joints
Preparation
All surfaces must be cleaned and free from contaminants that can interfere with the adhesion, including dust, dirt, grease and oil. Any old sealant or mastic must be removed.
Application
