The application method of spraying machine can be summarized as three steps: spraying, smoothing and calendering.
1. Spraying, feeding the mortar machine, adjusting the appropriate consistency of mortar, spraying, spraying thickness is slightly higher than about 1 mm of the standard reinforcement, the specific requirements are: spraying hand according to the situation of the standard reinforcement, according to the smooth situation of the wall as evenly as possible; guiding the spraying gun to move rapidly along the horizontal direction at a constant speed, can not do circular spraying; spraying wall mud in the spraying. When pulping, make sure that the spray gun is slightly upward warped, otherwise it is always sprayed on the wall at right angles; the distance between the nozzle and the wall should be 10-30 cm.
2. Flattening, after the completion of mortar spraying, it is necessary to immediately carry out flattening construction, with large scraper along the bar from bottom to top, with scraped material to find and repair the depression, as far as possible to achieve one-stroke flattening. If the mortar is thinning, it is not suitable for scraping immediately. If the mortar is slightly harder, use the 2 meter gauge board to check the evenness of the wall, scrape it slightly higher, and slightly lower it, and use the foam small washboard to rub it flat.
3, calender, calender time to master, mortar hand pressure, fingers no longer sticky mud when the best light, with foam washboard stained with water and rubbing, smooth iron trowel to press until the surface is relatively smooth and smooth.
