M&L for two coats of Quick Drying 1K Epoxy Primer by Removing existing paint of sheet metal enclosure of LT panels/Installation boards of surface area upto 10 Sqm complete by following manners • loose rust, mill scale from the metal surface by chipping, scrapping or by using any suitable solvent. • Sand the surface with emery paper 180 & wipe clean. • Use wire brush / machine tool to smoothen the rust pikes & sharp edges from the rusted surface. These rust pikes & sharp edges are difficult to coat completely & hence same needs to be smoothened before painting. • In case of welded joints, ensure sharp edges / pikes are smoothened with machine tool. These welded joints are highly susceptible to corrosion & hence for better protection, spot painting of these welded joints needs to be done with paint & allowed to dry before starting complete painting. • Clean the surface using solvent to remove greasy deposits, fine particles & dust. • Ensure the surface is clean & dry before painting all as specified and directed by Engr-in-Charge.
