COATING Wet the RCC substrate by sprinkling water. Apply 2 coats of DURAGARD (Cement based Polymer/Acrylic modified highly flexible waterproof coating) taking care the subsequent coat is applied after the previous coat is touch dry as per the l iterature of DURAGARD. The coats must be applied at right angles to each other @ 2 Kg per Sq mt. Glass fibre mesh should be laid between the two coats to impart extra tensile strength to the cementitious coating. The second coat should be followed by third coat of DURAGARD after the second coat is touch dry.

Spread cement mortar in 1:4 along with water-proofing compound over the brick bat coba. Press the cement mortar with a ruler of length of 2m. Level the surface with a wooden float, keeping 25mm thickness. Apply thick cement slurry over the levelled surface, along with the water- proofing compound for a smooth finish. Polish the surface with metal float Make vertical and horizontal lines at an intervel of 300mmX300mm, using a cotton line dori of minimum 3mm thick; so as to avoid cracking of the top layer.
