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.

Material Requirement:
PREPARATION
Use the following formula to determine number of
cartridges required –
Proper preparation is important to ensure the joint
system performs to requirements.
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.
