CLASSIC AQUA PRIME™ Iron and Galvanized Primer is a water-based, anti-corrosion and rust inhibiting etch primer that is specifically formulated for application onto properly prepared galvanized sheeting, galvanized iron surfaces, non-ferrous surfaces, and other metal surfaces in corrosive-industrial environments. It's suitable for both DIY projects and professional use.

  • Assists in inhibiting and prevention of corrosion, flash-rusting, and rust-creep.

  • Non-toxic and non-irritant.

  • Lead and chromate free, solvent < 5%.

  • Quick drying and time saving.

  • Excellent top-coat adhesion.

  • All equipment cleaned with water.

Alkali resistance combined with high penetration and exceptional adhesion power make CLASSIC AQUA PRIME™ a unique sealer for the subsequent application of premium-quality paints.


  • Completely non-flammable.

  • Outstanding results obtained in salt-air and industrial environments.

  • Highly recommended Rust Inhibiting Primer for Iron and Galvanized Surfaces.

  • Used in confined and enclosed spaces with no discomfort from obnoxious fumes or solvent odours.

  • For optimum results a two finishing coats are recommended over two applications of CLASSIC AQUA PRIME™ after correct drying time.

  • Can be overcoated with any commercially used type of paint, including Epoxies, Polyurethanes, Vinyl, Lacquers, Chlorinated Rubber, Coat Tars, High gloss Enamels and Fast-Dry or Quick-Dry Enamels.

  • THINNING  -  Not recommended, except for spray application.




  • Loose surface rust must be removed by manual or machine wire-rushing.

  • Fragment or brush all metal surfaces to be painted with sandpaper and/or wire brush.

  • Surfaces that have been subjected to salt air, must be brushed well to remove all deposits and washed off with Classic Etch Cleaner™ and then rinsed thoroughly with fresh water.

  • Remove all grease, oil and sanding residue with Classic Etch Cleaner™ and rinse thoroughly with fresh water.

  • Apply Rust Converter in presence of corrosion and leave to dry.

  • Apply one coat of Aqua-Prime and allow to dry for 4 - 8 hours before applying a second coat of Aqua-Prime.

  • Apply two finishing coats Premium Quality Paint over CLASSIC AQUA PRIME™ or CLASSIC CHASSIS AND BAKKIE™ on load bins and chassis after correct drying time.


  • Surfaces that have been subjected for at least on year of natural weathering - treatment as above.

  • New galvanised iron surfaces must be washed with Classic Etch Cleaner™ and then thoroughly rinsed off with fresh water.

  • Do not sand down.

  • Apply one coat of Aqua-Prime and allow to dry for 4 - 8 hours before applying a second coat of Aqua-Prime.

  • CLASSIC ROOF PROOF™ and / or membrane can now be applied to all water leaks, flashings, and screw tops.

  • Apply two finishing coats of CLASSIC SUPER ROOF™ on CLASSIC AQUA PRIME™ after correct drying time.

Aqua-Prime is a priming compound. For optimum results two finishing coats is recommended over two applications of Aqua-Prime. Any standard commercial type of topcoat, such as Econogloss, Satin Sheen, Classic Roof Proof™, Classic Super Roof™, Classic One on All™, Quick-Dry Enamel, Vinyl, Epoxy, Epoxy Coat Tar, Polyurethane, Chlorinated Rubber and Lacquer are suitable finishing coats.


Dry Aqua-Prime can only be removed or cleaned with wax-free paint remover.


  • The ambient temperature must be between 5ºC and 35ºC and humidity between 10% and 85%;

  • Do not paint too early as the wall may still be damp - paint only when the walls are dry;

  • Do not paint in too hot weather, rather paint early morning and after lunch, the slower the paint dries, the longer it lasts;

  • Excessive application thickness and/or rapid drying could lead to cracking;

  • Avoid applying under adverse weather conditions as this could result in poor product performance;

  • Excessively friable surfaces should be cleaned down prior to primer application.


Painting is a relatively user-friendly activity if the proper precautions are taken to ensure safety

  • Always keep out of reach of children and animals;

  • Do not take in orally - harmful if swallowed. Seek medical attention and do not induce vomiting;

  • If accidental contact with skin, wash immediately with soap and water or a good quality skin cleaner;

  • If accidental contact with eyes, rinse immediately with plenty of water and seek medical advice;

  • Do not let a freshly painted room be occupied, particularly not by older people, children, or pets;

  • Wear a respirator if the area being painted cannot be adequately ventilated, and work for short periods only;

  • Ventilate the area to be painted, opening all doors and windows and using fans during application and drying;

  • Protect floors with cloth dropcloths, not plastic, which is far more slippery;

  • Do not paint or store paint near any heat source such as a water heater or fireplace, and never smoke while painting;

  • Make sure your ladder is in good shape. Set the legs on an even surface and lock the cross braces. Do not stand on the top of the ladder nor on the utility shelf. If you are having difficulty reaching a spot, get down from the ladder and move it rather than leaning out;

  • Clean up carefully and thoroughly when you are done for the day;

  • If rags have alkyd paint or thinner on them, leave them to dry outside to avoid any chance of spontaneous combustion;

  • Choose an area inaccessible to children and pets, and when they are thoroughly dry, take them to a toxic-waste dump site.
