flat, smooth and uniform; there is no color separation binding on the large surface, and the allowable deviation of the small surface is not more than 2mm: the color is consistent, and the brush pattern is smooth; there is no missing brush, peeling and rusting The inspection of water / emulsion coating shall be carried out by visual inspection and hand feeling under natural light after the coating is dried The wall surface and top surface must be flat, free of powder falling, wrinkling and brush leakage, and the large surface shall be free of obvious color difference, alkali, back color and brush pattern, and there shall be no obvious sand holes, sagging, pimples and splashing Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
