Painting of 06 sets barrage bay vertical fixed wheel gates of size: 8300mm x 2000mm. after surface preparation by blast cleaning process, performed with sand as per requirements and class ‘A’ of IS: 14177:1994. After blast cleaning, the surface should be cleaned from loose dust and debris preparably by air blast with help of blower. Over the prepared surfaces, two coats of zinc rich primer( contaning not less than 85% zinc rich on dry film) should be applied to give a total dry film thickness of 70 ± 5 microns. First coat of primer should be applied within six hours of sand blasting. Finishing coat should consist of 02 coats of followed by two coats of solvent less coal tar epoxy paint.These should be applied at an interval of 24 hours. Each coat should give a minimum dry film thickness of 150 ± 5 microns. The total dry film thickness of all the coats including primer coat should not be less than 350 ± 5 microns as per IS: 14177:1994. The rare should include cost of sand, hire charge of air compressor, painting equipments, labour, other machinery, scaffolding etc. required for painting and as per scope of work & direction of Engineer-in charge.
