GALVANISED IRON & STEEL
(Also see ‘Zinc Sprayed Steel’)
Newly galvanized metal is usually smooth which hinders adhesion for paint
resulting in early failure of the paint by flaking. A suitable primer is needed to
overcome this situation. However, weathering of G. I. Sheet provides key to hold
paintings but should be coated with a suitable primer before finish paint is
applied.
Surface preparation:
Wash the surface with T-6 to remove all oily and greasy matters. Rinse with mild
detergent solution, to remove any other surface contaminants. Wash with clean
water & dry. For weathered surfaces check for any rust, corrosion and remove
rust (if any) by wire brushing / emery cloth. Dust off with clean dry cloth. Prime
as soon as the surface is prepared.
Painting:
For fresh surface:
1 coat Wash Primer
1 coat Zinc Chromate Primer/ Zinc
Phosphate Primer
2 coat Robb. Super Gloss Synthetic Enamel.
For Weathered surface:
1 coat Zinc Chromate primer/ Zinc
Phosphate Primer
2 coat Robb. Super Gloss Synthetic Enamel.
For structures near to sea coast or saline atmosphere apply Chlorinated Rubber
Red Oxide Primer followed by 2 coats Chlorinated Rubber paint. For fresh G. I.
Surface, an initial coat of Wash Primer is a must.
