RECOMMENDED USES:

 

For application to all wood surfaces, where a reduction of surface burning characteristics is required to comply with building code requirements. USED BY: Schools, Colleges, Nursing Homes, Child Care Centers, Hospitals, Penal Institutions, Apartments, Hotels, Factories, Warehouses, Retail Stores, Restaurants, Utilities, Railroad and other Transportation Companies, Oil and Chemical Installations, Military Installations, and other facilities where fire retardant coatings are required.

 

PERFORMANCE INFORMATION:

 

Class “B” fire rated on wood when applied in two coats at 400 sq.ft./gallon per coat. - See Fire Hazard Classification Section. Complies with federal, state, local building and fire code requirements. Does not leach (lose fire retardancy) on exposure to high humidity. Meets all current environmental regulations.

 

SURFACE PREPARATION:

Surfaces must be dry, clean, free of all wax, grease, dirt, sanding dust, etc. Glossy surfaces must be dulled with sandpaper or steel wool. For best appearance, new, previously uncoated surfaces should be sealed with a thinned down coat of No. 141 (1 pint of mineral spirits per gallon of No. 141) or other suitable wood sealer (do not use lacquer-type sealers). All sanding, filling of nail holes, etc. should be completed prior to the application of No. 141.

APPLICATION:

Burn Barrier No. 141 can be applied by brush, roller or spray. If sealer has been applied, allow surface to fully dry before applying No. 141. Stir material well before using, then apply a uniform coat at a coverage rate of approximately 400 sq.ft./U.S. gallon (9.8 m2/L). The coverage rate will vary, depending on the porosity of the surface. Allow to dry overnight or until hard. Lightly sand, clean dust from the surface, then apply a second coat at the same coverage rate. Note: Two coats are required to comply with the Class “B” fire retardant rating established.
