Slurry throwing: the basic treatment before plastering should meet the design requirements. Treatment suggestion: the density and burr feeling of the size must meet the requirements when spinning again. Problem: the plastering layer is cracked and empty. Reasons: unreasonable treatment at the grass-roots level, large silt content in sand, failure to hang nets as required, and untimely maintenance. Specification requirements: there should be no hollowing and cracks on the surface of plastering layer. Treatment suggestion: after knocking off the cracked plaster, sprinkle water in the basement and hang a net to plaster again.
