This product, intumescent mastic, comes to you in a 310ml cartridge. It is important for sealing gaps that form around cables, joints, windows, voids, pipes, fire doors and small holes present in fire-rated structures. It is available in brown, white and grey and fills gaps ranging up to 25mm in width without slump and is easy to over-paint. The mastic we offer has fire resistance reaching 4 hours and is therefore suitable for interior use, apart from boasting long shelf-life.
