Application Temperatures:
Should not be applied to cold metal at or below the dew point or hot metal above 40^oC (105^oF). The coating gives excellent protection at temperatures between -50^oC (-60^oF) and 50^oC (112^oF) continuous use.

Surface Preparation:
Remove loose scale, flaky rust, all old paint and dirt with wire brush etc. Salt water deposits must be removed with high-pressure clean water blasting. Reduce any high peaks of rust. IMPORTANT - high peaks must be adequately covered by NEUTRA RUST 661. Alkali, grease, oil, salt and chemicals must be removed with detergent water, wash and then rinse surface with cold clean water. Paintwork blistered by rust must be scraped down to the hard rust surface. DO NOT REMOVE ALL TRACES OF RUST. RUST IS NECESSARY FOR THE COMPLETE
REACTION OF NEUTRA RUST 661 TO TAKE PLACE. NEUTRA RUST 661 MAY BE APPLIED T0 DAMP RUSTED SURFACES. Areas of deep pitting - work NEUTRA RUST 66l well in with brush.

Dispensing:
CONTAMINATION OF NEUTRA RUST 661 - before use pour into non-metallic container. To avoid the transfer of rust particles into NEUTRA RUST 661 container do NOT pour unused portion hack into original NEUTRA RUST 661 container. Clean brushes/equipment with cold water or detergent wash. This also applies to any spillage that may occur.

Application:
For inland atmosphere - 2 coats are recommended for conversion and protection. Highly corrosive environments, i.e. salt water/marine, desert sand, chemical environments/tanks etc. apply 3 coats of NEUTRA RUST 661. NEUTRA RUST 661 is self-priming and will accept most paints for overcoating, for extended life or for cosmetic finish. Overcoat paint must be tested for compatibility with NEUTRA RUST 661 before full-scale painting. Chemical liquid tanks or shipping applications, below the 'water line', overcoat with epoxy etc. and leave 7 days before immersion. Drying times:
Each coat (approximately) touch dry - l5mins 45mins dependent on temperature and humidity. Between coats - 1 hour after touch dry. Protect from rain during drying. In confined areas, i.e. tanks, cellars etc. high humidity and low temperatures can delay drying time. Continuous warm air circulation is required to accelerate the drying process. Flash rusting may occur under the following circumstances: If
NEUTRA RUST 661 is applied too thinly. Temperature is below 5⁰C - drying time delayed. Salt deposits not removed from rust. Weld areas - flux salt deposits not removed.

Product Testing:
NEUTRA RUST 661 must be left 7 days before physical or chemical testing is carried out.

Adhesion:
Cross-hatch over rusted steel GtO, less than 5% removed.

Permeability:
20-25g/m/25mm/day.

Chemical resistance:
Spillage-resistance to acids and alkali splashes. Not resistant to prolonged contact with aliphatic or aromatic solvents. Prolonged contact with solvent causes softening which will recover.
