Intumescent paint application



Fire proof paint - how it works.Intumescent paints and coatings produce a protective char retarding the spread of flames and the transfer of heat in the event of a fire,

Astroflame stock a range of protective intumescent coatings, for steel, timber, plaster and brick and a range of decorative finishes to protect and complete fire protection systems.

These types of decorative finish are also referred to as fire proof paint, fire retardant paint or fire varnish (clear coat)

ASTRO ISS Intumescent Paint insulates structural steel and cast iron steel during a fire, keeping them below the critical (collapse) temperature.

ASTRO ITC and ASTRO IF Intumescent Coatings control flame spread and fire propagation on wood.

Fire retardant and flame retardant paints assist in the control of fire hazards from combustible materials, such as wood, by releasing a flame extinguishing gas when exposed to the high temperature of a fire.

Fire proof paints can be used on new or old surfaces. Improved fire resistance can be imparted to accumulations of flammable paint (due to repeated overpainting) on old plaster or brickwork by applying an intumescent coating and a flame retardant paint decorative top-coat.

Where a fire resistant paint has been specified and the client needs assurance that the specification has been met we issue a certificate of supply (on request).
