Painting of Piers and Segments of Six Lane Elevated Corridor on NH-66 from Ch.508.000 to 513.150 at Porvorim.

Providing and applying an elastic elastomeric membrane forming system with anticarbonation and berathing properties. The system (EMCECOLORFLEX + PRIMEX 250) or equivalent should be based on solvent free acrylic polymers with solid contents of 70 + 3% and should be ultra violet resistant, crack bridging type, water-proofing coating. For anti-carbonation, equivalent Air layer thickness denoted as R or SD CO2 > 50 m and for breathability equivalent Air layer thickness denoted as SD H20 shall be < 4 for vapour transmitting barrier. The system consists of one coat primer at 75-100 g/m2. The consuption of polymer coating to give film thickness of 200-225 microns should be approximately 400-450 gms/m2 per two coats. Polymer coating should be in suitable approved shades, including suitable surface preparation, cost of materials and labour for applying the above coating, and scaffolding charges, all inclusive of taxes.
