WALLCOATIntumescent for walls and ceilings |
A COST EFFECTIVE ANSWER TO A SERIOUS PROBLEM Inherently non-combustible surfaces such as plaster- board and brick can become a potential fire hazard due to repeated redecoration with conventional paints. Different paint types from a variety of manufacturers have generally been used over many years with less than thorough preparation. In a fire thick layers of old paint tend to delaminate rapidly catching and spreading fire around a building. In extreme cases a lethal “flash- over” fireball effect is created. The resultant risk to life and property can be greatly reduced at minimum cost using a combination of Thermoguard Wallcoat, an insulating “intumescent” barrier coating and Thermoguard flame retardant paint. DESCRIPTION AND USE Thermoguard Wallcoat is an intumescent undercoat for application to previously painted plaster, Artex, board, brick and concrete walls and ceilings. Overcoated with Thermoguard flame retardant paint it insulates old paint films from fire, controlling the spread of flames along walls and ceilings. TO SPECIFY Simply state: |

INTUMESCENT AND FLAME When exposed to a fire Thermoguard flame retardant paint releases a flame extinguishing gas which instantly protects the surface. Simultaneously heat activates Thermoguard Wallcoat underneath causing it to expand and create a fire protective barrier, insulating old paint films from heat and oxygen. |
