55.26a:Providing and applying elastic, elastomeric membrane forming system with anticarbonation and breathing properties. The system should be based on solvent free acrylic polymers with selected mineral fillers and should be ultra-violet resistant, crack bridging type, carbonation resistant, breathable, enviornment friendly, water proofing coating. For anticarbonation, equivalent air layer thickness denoted as R or SD CO2 grater than 50 m and for breathability equivalent air layer thickness denoted as SD H2O shall be less than 4 m for vapour transmitting barrier. The system consists of one coat primer @ 75- 100 g/m2. The consumption of main polymer coating to give film thickness of 200-225 microns (Solid contents- 70%+ -3%) should be approximately. 400-450 g/m2 per two coats depending upon the method of application (either by roller or brush) and surface smoothness of the concrete. The total dry film thickness of the coating system should be minimum 200 microns for the above system. Polymer coating should be in suitable approved shades, including cost of materials, cleaning, chipping and removing the dirt particles of the concrete slab with wire brush and water,labour charges for filling the bug holes, cracks, joints etc with one component polymer modified fine repair and cosmetic mortar, labour for applying the above coating, scaffolding charges,etc. complete as per IRC SP:80 Clause 6.5.1 and Clause 2808 in the Specifications Book for Roads & Bridges published by the Ministry during April 2013.
