Application Guide
FOSTER FIRE RESISTIVE ALUMINIUM MASTIC 60-75
Application
Cold storage vessels: Fire Resistive Aluminium Mastic 60-75 will provide a weatherproof water vapour barrier on cold
storage vessels to reduce the transmission of water vapour towards the cold surface and avoid failure of the insulation
system.
Specification/ Site Instructions

Guide Specification:
1. The mastic as detailed shall be Fire Resistive Aluminium Mastic 60-75.
2. All surfaces must be dry and free of contamination, all joints sealed and any damage made good before application.
3. Using a clean trowel apply a first coat of Fire Resistive Aluminium Mastic 60-75 at a uniform rate of not less than 1
2
litre/m to give a minimum applied film thickness of 1 mm.
4. Immediately embed Open Weave Glass Cloth No. 10 into the coating whilst wet, applying a light pressure from the
centre to the edge. Allow a minimum of 50 mm overlap at all adjoining edges, protrusions and terminal points.
5. Allow at least 16 hours for the first coat to dry.
6. Ensuring that the first coat is dry and contamination free apply a second coat of Fire Resistive Aluminium Mastic 60-75
2
at a uniform rate of not less than 1.5 litre/m to give a minimum wet film thickness of 1.5 mm.
7. Allow a minimum of 3 days after the application is complete before putting the plant into service.
Site Instructions
Store Fire Resistive Aluminium Mastic 60-75 within a range of 15°C to 25°C for 24 hours prior to use. Cut the reinforcing
membrane to the required shape and size before application of the first coat. Care must be taken during application to avoid
the inclusion of air in the wet coating. Where practical, application equipment shall be cleaned, part and used containers
closed and maximum ventilation made available at the end of each working session.
