Rapidri Coatings
For Terne II Roofs

Rapidri is a water-based acrylic painting sytem that’s formulated specifically for Follansbee Terne II roofs. Fast-drying Rapidri eliminates long delays between primer and finish coats, minimizing the threat of inclement weather, and speeding the job to completion - usually under two days. Plus, Rapidri primer and finish coats may be applied by spray equipment, roller or brush and is available in twelve attractive standard colors.

Specifications

RAPIDRI WATER BASED ACRYLIC PRIMER

General description: Follansbee RAPIDRI primers are single component, water based acrylic emulsion polymers and are designed to be used as air-drying, rust-preventative ferrous metal primer paints. These coatings exhibit very good flexibility and exceptional adhesion. In addition, they are very forgiving of less than perfect surface preparation, offering substantial savings in preparation costs. However, surface must be chalk free to assure good adhesion. RAPIDRI primers are available in a red oxide and gray color.

These paints are very high in solids, permitting a thicker dry film build over hard to protect sharp edges. And best of all, these products contain very low levels of volatile organic content, resulting in reduced toxic or flammable solvent vapors and hard-to-dispose of listed hazardous wastes in the workplace. They comply with all current environmental regulations.

Surface preparation: Surfaces to be coated with RAPIDRI must be clean and dry. All surfaces must be free of chalk, dirt or debris at each stage of application. If roof area needs cleaning before painting, clean the roof surface by using a stiff bristle brush and TSP (Tri-Sodium Phosphate) or a mild liquid detergent, bleach and water solution. Brush the entire surface area. DO NOT WIRE BRUSH, SCRAPE OR ABRADE SURFACE. You may also use a power pressure washer with TSP or mild liquid detergent, bleach and water solution to get the same result. After cleaning, rinse the area with a clear water to remove any detergent and allow the metal to thoroughly dry prior to applying

UNDERSIDE: On pitched roof areas (3" or more per foot), a mill applied shop coat or a coat of RAPIDRI Primer must be applied before application. On flat locked areas (less than 3" per foot), a coat of RAPIDRI Primer must be applied even though a shop coat has been applied at the mill.

EXPOSED SURFACE:Apply two coats. The mill-applied shop coat is not to be considered as one of the two coats required on the exposed surface. First coat to is to be RAPIDRI (primer); second coat is to be RAPIDRI (finish coat). Application method: These paints may be applied by brush or roller (3/8" nap roller is recommended), or airless spray equipment. Use .015 or .020 inch spray tip size. Do not apply with a cup type spray gun. Typical recommended dry film build per coat is between 3 and 5 mils. Application of two or more coats to achieve an average of 4mils may be required to achieve optimum product performance. Drying time: Dries to recoat in 24 hours at 77 degrees F and 50% relative humidity. High humidity will prolong dry time more so than low temperatures. Good air movement over the work or local exhaust is recommended, but heat lamps are not suitable. Do not re-coat until preceding coat has dried. Surface and air temperatures should be between 50 and 90 F and remain above 50 while painting and drying. Thinning and cleanup: May be thinned under mild agitation with water to a maximum of 5% by volume, do not use organic solvents. Cleans up easily with soap & water before the paint dries hard. Packaging: Product comes in 1 and 5 US gallon buckets.

RAPIDRI WATER BASED ACRYLIC FINISH COAT

General description: Follansbee RAPIDRI Finish coatings are single component, water based acrylic emulsion polymers, and are designed to be used as a brush, spray, or roller-applied direct-to-metal medium gloss topcoats over properly primed and prepared Terne II surfaces. They are very forgiving of less than perfect surface preparation, offering substantial savings in preparation costs. However, surface must be chalk free and clean to assure good adhesion. RAPIDRI finish coatings are available in 12 standard colors.
