Surface Preparation

New Construction: No sandblasting required. Remove any loose mill scale. Welding flux residues must be removed by wire brushing followed by washing with clean water. Clean up all debris. If surface has been shop primed with inorganic zinc, do not coat until the zinc has been cured a minimum of 30 days.

In Service Equipment: No sandblasting required. Remove flaking rust and peeling paint. Break all blisters larger than 25 mm (one inch). Remove all standing water. Clean up all debris and silt. May be applied over tightly adhering rust. Residual coal tar and asphalt coatings must be removed to leave a thickness of no more than 50 microns (0.002 inches). If surface is heavily scaled, consult your Eureka representative. For further details, see Technical Bulletin #202.4.

Number of Coats

1

Typical Coverage Per Drum

170m 2 (1,833 ft 2 ) at 1.23 mm (48mils) thickness for new steel.
146m 2 (1,571ft 2 ) at 1.44 mm (56 mils) for rusty steel.
On very heavy rust, visual inspection is required for best thickness recommendation.

Thinning

Do not thin.

Curing Time

None. Equipment may be used immediately after coating.

Methods

Airless spray, roller, brush.

Heating Required

Under extreme cold conditions, storage of material in a warm room will facilitate application.

Spray Equipment

Graco Fire-Ball 300 Grease Pump, 50:1, for 400lb (180kg) drum, model #239888. Gun: Graco Pistol Grip Flo-gun model: 207-945, series B; or an Alemite 7896 pump (22/1 ratio) or equal, and a flow gun. See Technical Bulletin #202.1.

Clean Up

Scrape off excess then wash with hot water and mild detergent or any commercial degreaser.

Protective Equipment

When spraying use approved eye protection to safeguard against potential eye contact. Use respirator or gas mask with appropriate cartridges and canisters (NIOSH approved, if available) to remove oil mist. If making repairs by brush, a respirator is not required.
