Fire Integrity - 4 hours fire integrity Safety Benefits: • • • • • Benefits Legislation Compartment walls and floors must maintain the appropriate level of fire resistance as laid down by Building Regulations Approved Document B 1991. Movement joints in walls, floors and joints at the head of walls need a product that can provide movement and at the same time provide up to 4 hours integrity. Avimastic satisfies all these requirements. Manufactured under ISO 9001:2000 Quality System. Application One part intumescent acrylic sealant Swells in a fire to give a smoke and fire resistant seal Halogen and solvent free Resistant to fungus, mould Fire rated up to 4 hours (depending on joint design) Avimastic Acrylic Sealant is high quality fire rated sealant. All surfaces must be clean, dry and free from dirt, grease and loose particles remove nozzle and cut to the required diameter, cut off cartridge tip and screw on nozzle. Ensure that the sealant is forced into the joint so that full contact is made with joint surfaces. Use joint backing rod to control sealant depth and assist in correct joint design. Smooth with wet tooling knife. Surrounding areas may be masked off to protect / prevent contamination.

Gap Width (mm)XDepth (mm)X Total Length (mm) 310 = No of Cartridges The surface must be free from dust, loose particles, moisture, oils, grease and corrosion before commencing installation. Specification Avimastic has an excellent adhesion and doesn’t require any primer before use. “Install Avimastic (colour) fire seals in full accordance with manufacturer’s instructions. INSTALLATION INSTRUCTIONS Health and Safety It is recommended that joints should have a minimum width of 5mm. Keep out of reach of children Avoid contact with skin and eyes Wash hands after use Do not ingest For optimum performance ratio is 2:1 width:depth. A minimum depth of 10mm should be used. Safety Data Sheet available on request. Apply AVIMASTIC against a firm backing rod so that it is forced against the sides of the joint, to ensure good adhesion. The correct installation of the backing material enables the required shape and profile of the seal to be achieved. The Backing Rod should be oversized to match the joint width enabling it to resist movement during installation. Storage Store between 5°C and 25°C Shelf Life: 12 months Protect from frost. Maintenance: Routine inspection recommended to ensure no damage. No maintenance required after installation. Do not use none flexible material as backing rod such as polystyrene boards. Material Requirement: Avimastic is waterborne fire resistant acrylic gap mastic for use in structural, low-movement joints (movement ± 5%). INSTALLATION CHECK LIST • Determine the correct depth of seal required to achieve the fire rating. • Use fire rated backing rod oversize to joint to obtain correct seal profile. • Ensure that the contact faces are suitable for sealant application. • Ensure that the width of the joint is within the Product Specification. • Abrade all painted areas surfaces to form a key for Avimatic. • Ensure all contact areas are dry and free from any dirt and loose particles and contamination.
