When a fire batt intumescent fibre board is cut to size, its cut edges need to be coated with this mastic which can be sprayed or painted on. For this purpose, we introduce to you our Astrocoat mastic. In a fire situation, this mastic causes the fire batt intumescent fibre board to change into a hard ceramic, sealing holes created by pipes, cables, cable trays and ducts and ultimately preventing fire from passing through those holes.

Our NHBC approved Astrocoat mastic has been duly tested in accordance with BS476 Part 20 and EN 1366-3 and can withstand the heat of fire for up to 4 hours.
