Removal of old seals after unscrewing the bolts and nuts from angles and plates by means of applying antirust solution and stacking the useful materials for re-use (labour only) . Setting new bottom seals in position putting the old flat over it in proper position and making holes to seals by means of punch to suite the bolt inside the available old holes of flat and in skin plates and fixing with washer and tighteaning up to maximum rigidity per gate.

Surface requires sand blast cleaning should be sand blasted. Heavy deposits of grease or gear oil may be removed by the solvent like clean mineral, spirits, white gasoline etc. prior to sand blasting. Small quantities of grease or oil may be removed by blasting process in which case however the abrasive should not be reused if it contains sufficient oil or grease to render it unsuitable for blast cleaning purpose. The average surface roughness after sand blasting should not be 30-40 micron. After blast cleaning the surface should be cleaned from loose dust and debris preferable by air blast with the help of blower and removing loose scales, blisters, rust, old coating and other contamination etc from old painted surface subject to submergence in water such as condition of dam gates. Sand blasting should be carried out confirming to IS 1477 (part-1) of 1971 adhrerence to the rate of 15 to 25 Sqm/nozzle hour using 8 mm nozzle at pressure of 7kgf/Sqcm Class-B or Sweden Standard 2.5 including all equipment, materials, scaffolding, labour charges and including all costs incidental to the work and Providing priming one coat with Epoxy based primer [(Epilux 610), painting First coat with anti-corrosive epoxy based black paint HD (EPLLUX 555 HD or Equivalent), Second coat with anti-corrosive epoxy based black paint HD (EPLLUX 555 HD or Equivalent) as directed by the Engineer-in-Charge of the site.
