The masonry surface must be cleaned by removing the loose dust, dirt, all paint particles, flakes of previously painted film, grease etc. with the help of a wire brush. In case of organic growths like fungus, it should be removed using mild solution of household bleaching powder (recommended proportion 2kg to 50 Its water), leaving it for 24 hours and then washing the surface with clean water. For external application to common bricks, it should be ensured that these bricks are dry at the time of application and the design of structure ensures maximum protection from moisture penetration. Fill the bigger cracks using cement & sand mixture in the ratio of 2:3. Extra care should be taken for surfaces like sunshades, parapets and other horizontal surface where water accumulates during rains.

Wet the surface by spraying sufficient water and allow the surface to partially absorb the water leaving a damp surface. Now the surface is ready for painting. The first coat of Cement Paint should be applied on the surface to form an effective bond for the subsequent coats. Cure the painted surface by spraying water after 8-10 hours of painting depending on the atmospheric conditions. The second coat should be applied minimum 8-10 hours after the application of the first coat, after which normal curing should be done. Curing should be done 3-4 times for the second coat also for next three days. The painted surface gets hard with resistance to water absorption and becomes washable. Curing is essential because the quantity of water added in the mix is not sufficient to complete the hydration process. With proper curing, more strength is achieved in the cement film. Cement Paint should be used within 12-18 months from the date of manufacturing.
