BURN Barrier No. 400 Semi-gloss Acrylic is a Class “A” rated, water base, general purpose, fire resistant
paint, designed for use on all interior and exterior surfaces, except floors, where maximum durability
coupled with fire resistancy is required. No. 400 may be utilized as an overcoat on most intumescent type
fire retardant coatings to improve their cleansibility, scrubbability, and overall durability.
Surface preparation should be carried out according to good painting practices. Remove all loose, peeling
or powdery paint from the surface. All dirt, grease, oil, wax, and other foreign matter MUST be removed
with a detergent. Rinse surfaces thoroughly with clear water and allow to dry. Repair all cracks, holes,
and other surface irregularities. Allow to dry, sand lightly and prime repaired surfaces with No. 400.
New and Previously Painted Surfaces:
BURN Barrier No. 400 can be applied directly to most surfaces. Metal surfaces must be primed with a
good quality metal primer. On combustible surfaces where maximum fire protection is required, a coat
of BURN Barrier intumescent fire retardant paint should be applied before the application of Flame
Control No. 400.
