EM PARTS: Surface cleaning of metal surfaces by chemical cleaners and then by hand and power tool cleaners and Removing dust. After cleaning,applying primary coat with one coat of Protective Mastic to athickness of 70+5 microns,followed by finishing coats 2 coats with Solventless Coal tar epoxy each coat with a DFT of 150+5 microns and total DFT of all coats including Primary coat should not be less than 350 mucrons with material, labour and all accessories with all leads and lifts (in respect of Heavily rusted (30 to 40% rusted) surfaces)

GATES: Surface cleaning of metal surfaces by chemical cleaners and then by hand and power tool cleaners and Removing dust. After cleaning applying primary coat with one coat of Protective Mastic to athickness of 70+5 microns followed by finishing coats 2 coats with Solventless Coal tar epoxy each coat with a DFT of 150+5 microns and total DFT of all coats including Primary coat should not be less than 350 microns with material, labour and all accessories with all leads and lifts (in respect of Heavily rusted (30 to 40% rusted) surfaces

Surface cleaning of metal surfaces by chemical cleaners and then by hand and power tool cleaners and removing dust. After cleaning,applying primary coat with two coats of Zinc chromite rod oxide primer followed by finishing coats 3 coats with synthetic enamel paint with material, labour, and all accessories with all leads and lifts where surface cleaning by sand blasting is not feasible and based on specific recommendations of designers, it is to adopt surface preperation done manually by hand and power tool after cleaning by chemical treatment to remove grease, rust, scaling etc., and to form phasphate coating to prevent further rasting. belore applying primer painting.
