Features

• Rust inhibitor: Prevents formation of rust and existing rust from spreading.
• Adhesion: Excellent adhesion to firm, clean rust and weathered galvanised iron.
• Overcoating: Can be overcoated with Prominent Universal Undercoat, Prominent Gloss Enamel and emulsion paints with high resin content after 24 hours.
• Waterbased: Easy to clean, easy to apply.
• 100% lead free.

Intended Usages

• Primer onto firm, rusted metal surfaces.
• Primer onto weathered galvanised iron.
• Primer onto weathered, oil free metal.

Application Details

• Mixing: Stir before use with a flat paddle to an even consistency. Stir occasionally during use.
• Method: Roller, brush or airless spray.
• Thinning: Not recommended.
• Cleaning: Remove as much of the product as possible from the application equipment before cleaning with tap water when wet, ProGold Lacquer Thinners when dry.

Conditions:

• Temperature between 5°C and 40°C.
• Relative humidity of less than 85%, preferably between 10: 00 and 16: 00.

Drying time: 
1 hour. 
Note:  Higher temperatures will accelerate the drying times (approximately halved for every 10°C increase), whilst lower temperatures will retard the drying time (approximately doubled for every 10°C decrease).

Recoating time: 4 hours.

Overcoating time: 24 hours.

Requirements: Two coats or more depending on measle corrosion test results.

Surface Preparations
Rusted & New metal:

• Remove all rust mechanically, degrease with ProGold General Purpose Cleaner/water mixture (1: 5) and abrasive pad.
• Rinse with running water or high pressure water, allow to dry and apply 2 coats.

Weathered galvanised iron:

• Loose rust and oxidation must be mechanically removed.
• Clean with ProGold General Purpose Cleaner/water mixture (1: 5) and abrasive pad to a water break-free surface.
• Rinse well and allow drying before applying 2 coats.

New galvanised iron:

• Remove fabricators pre-treated oil and any other contamination with ProGold General Purpose Cleaner/water mixture (1: 5) and abrasive pad to remove any oily layer or oxidation and rinse thoroughly with portable water, allow drying.
• Ensure that a water break-free surface is obtained.
• Apply one coat Prominent Galvanised Iron Primer.

Measle corrosion test:

• Prepare the surface as set out under new work.
• Apply to a test area one coat and to another test area a two coat applications of Prominent Rust Primer Grey. Allow to dry.
• Overcoat the test areas with white PVA and allow drying for 4 hours.
• If rust spots are visible on the 1 coat application of Prominent Rust Primer, but not the two coat application, then two coats would be required.
• If rust is still visible on the two coat application, then either more sanding is required to flatten the rust peaks or a third coat of Prominent Rust Primer is required.

Previously Painted Surfaces with Rust: 

• Remove all paint back to bare surface in rusted areas.
• Treat as new work.

Limitations

• Must be used only as a primer, not as a finishing coat.
• Exterior surfaces must not be exposed to rain within 12 hours of application.
• Application conditions must be adhered to.
• Prominent Rust Primer should not be overcoated with Prominent Machinery enamel products and strong solvent products e.g. Prominent 2-Pack Polyurethane floor coating.
• Product not UV resistant.

Safety

• Keep out of reach of children.
• Ensure to maintain good ventilation during application and drying process.
• In case of skin contact, wash with soap and water or a recognised skin cleaner. Avoid contact with eyes. In case of contact with eyes rinse immediately with running water and seek medical advice.
• If product is ingested drink plenty of water or milk. Do not induce vomiting at any time. Seek medical advice.
• Refer to the Material Safety Data Sheet (MSDS) for detailed information about the product and transportation and classification criteria. MSDS is available on www.prominentpaints.co.za or from Prominent Customer Service Department.
• To avoid any risk of spillage, always transport in a secure upright position.
