NO. 40-40 LOW-GLOSS LATEX FIRE RESISTANT COATING
PRODUCT DESCRIPTION:
No. 40-40 IS A LOW-GLOSS GENERAL PURPOSE LATEX [Water base] coating, that is fire rated over noncombustible surfaces, and as an overcoat for intumescent fire retardant paints. It dries quickly to yield a highly cleansible, scrubbable, water resistant film that possesses excellent adhesion, flexibility, and toughness. No. 40-40 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:
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. 40-40.
NEW SURFACES:
No. 40-40 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 intumescent fire retardant paint, before application of No. 40-40.
PREVIOUSLY PAINTED SURFACES:
Noncombustible surfaces having excessive conventional paint film build up, and all combustible surfaces such as wood, plywood, fiberboard, etc., must be coated with intumescent fire retardant paint, before application of No. 40-40.
APPLICATION:
No. 40-40 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 50 F [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 re-coated in 1 to 2 hours.
THINNERS:
For thinning, use only water [maximum 1/2 pint per gallon]. For equipment cleanup, use warm soapy water.
