Blakite is a highly refractory mortar, dark grey in colour, which has a high water retention characteristic. It was specially developed for laying insulating firebricks but is also suitable for use with super duty and high alumina dense refractory bricks, at operating temperatures up to 1650 °C.
It is supplied in a consistency suitable for shallow patching or trowelling, but requires the addition of approximately 5% water for dipping. Blakite is a good choice as a single, general-purpose mortar on projects involving mainly insulating firebricks but also including some dense firebricks.
