Painting of Spillway gates, sluice gates, canal gates (both vertical or radial), stop log gates, exposed embedded parts and all un machined ferrous surface (hoist cylinders, cylinder heads, hydraulic piping, pipe fittings, bonnet covers), exposed to water as per IS 14177,for which surface preparation by blast cleaning of class "B" primer coat (one coat) of inorganic zinc silicate (preferably airless spray)or alternatively, two coats of zinc rich primer(containing not less than 85% zinc on dry film) to give dry film thickness of 70 ± 5micron and finish coat (two coats) of solvent less coal tar epoxy paint using airless spray to provide dry film thickness of 150±5 micron per coats. Thus, total dry film thickness of all the coats, including primer coating, should not be less than 350 microns, this will be include expenses on mobilisation and demobilisation of equipment’s. For maintenance painting the surface preparation shall be done by appropriate hand and power tool cleaning, prior to hand power tool cleaning any heavy layer of rust should be removed by chipping visible oil, grease, dirt and other foreign material be cleaned using solvents like clean mineral spirits, xylot or white gasoline. After hand and power tool cleaning the surface should be cleaned of loose dust and debris and/or blast cleaned as laid down in para 7.0 of IS code 14177. After the surface preparation the primer and finishing coats shall be carried out as provided above for painting.Up to 1.5m height
