Would this product be used to seal joints/inside and outside corners of 60min 15mm gyproc fire board, to seal fire board around structural steel posts? If Yes what is the drying time, can it be decorated over and what is the coverage of a 20kg bag.


Generally we propose the use of Nullifire FB750 Coated Batt for primary seals or Nullifire FS702 Waterborne Intumescent Acrylic Sealant for linear gaps.

Nullifire FR220 Firestopping Compound could be used, but is generally only required for load bearing floor seals and may cause mould if the plasterboard is not appropriately treated. Please see details for batt and mastic solutions on the above links. These products can be over coated with any standard trade emulsion to achieve a decorative finish. Over coating can be completed after 30 days (full mastic curing time).
