Zeroflame Intumescent Fire Retardant Varnish consists of a two pack water borne base coat, and a solvent based finish coat available in Matt, Satin, or Gloss.

Suitable for use in public buildings, schools, housing, shopping centres, restaurants, banks, churches and for walls and ceilings in escape routes where timber or wood derivatives are used, suitable for most types of softwood and hardwood in new and existing structures. Can be applied by brush, roller or spray.

When attacked by fire, Zeroflame Varnish will retard the spread of flame and reduce the contribution the substrate would normally make should fire occur, the varnish expands to form an insulating layer of non-combustible rigid foam which stops the spread of flame across the surface and reduces the release of combustible gasses.

Successfully tested to BS476: Part6&7 (1987) achieving Class O and Class 1 flame spread and fire propagation on internal wooden surfaces.
