HOIST: Painting of Sluices for Maintenance works: 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 coat of Zinc Chromite Red oxide primer followed by finishing three 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 preparation done by manual and power tool after cleaning by chemical treatment to remove grease, rust, scaling and to form phosphate coating to prevent futher rusting, before applying primer painting.
