Burn Barrier™ 40-40A
BURN BARRIER™ NO. 40-40A LOW-GLOSS LATEX FIRE RESISTANT COATING
BURN BARRIER™ No. 40-40A is a low-gloss general-purpose latex (water base) coating that is fire rated over noncombustible surfaces, and as an overcoat for BURN BARRIER™ intumescent fire retardant paints. It dries quickly to yield a highly cleansable-scrubbable, water resistant film that possesses excellent adhesion flexibility, and toughness. No. 40-40A is suitable for application to all interior surfaces (except floors and shelving). It can also be used on exterior masonry surfaces where a highly water resistant, decorative coating is desired.
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. 40-40A.
New Surfaces: BURN BARRIER™ No. 40-40A can be applied directly to primed steel and directly to all other noncombustible surfaces. All combustible surfaces such as wood, plywood, fiberboard, etc., must be coated with BURN BARRIER™ intumescent fire retardant paint, before application of BURN BARRIER™ No. 40-40A.
Previously Painted Surface: Noncombustible surfaces having excessive conventional paint film buildup, and all combustible surfaces such as wood, plywood, fiberboard, etc., must be coated with BURN BARRIER™ intumescent tire retardant paint, before application of BURN BARRIER™ No. 40-40A.
BURN BARRIER™ No. 40-40A is ready to use. It can be applied by brush, roller, airless or conventional spray equipment. Stir thoroughly and apply, using a full-bodied coat. If thinning is required, use WATER only, do not exceed 1/2 pint per gallon. Do not apply in temperatures below 50F (10C).
Suggested Coverage Rate: 350 to 625 sq.ft./U.S. gallon (8.6 to 15.3 m2/L) depending on substrate. See fire hazard classification for specific coverage rates.
Drying Time: Dries to touch in approximately 30 minutes, can be recoated in I to 2 hours.
Thinning: For thinning, use only water (maximum 1/2 pint per gallon). For equipment clean up use warm soapy water.
