Curing compound application on horizontal surfaces

?Performance of a curing compound is dictated largely by the methodology exercised in its application. Curing compounds can be applied by spraying, brushing, or roller-painting. Spraying is the preferable choice for horizontal surfaces because the curing compounds are applied before the concrete has finally se[preferably 3-4 hours of placing concrete]t. On the other hand, both spraying and brushing can be used for formed surfaces. Spraying is the preferred choice for larger surfaces, particulars involved in the spraying operations must be properly taken care ?to achieve a uniform coverage . Different factors that are to be considered are type of nozzle used, air pressure , height or distance of the nozzle from the surface, spacing between the nozzles, speed of the nozzle over the concrete surface particularly time of start of the application. Curing compound solids have a high tendency to settle. So, curing compounds must be vigorously stirred before using them and curing compound drums to be kept below shades.
