821 putty powder presents problems and countermeasures in home decoration. After home decoration, it may not pass for a long time, and the originally flat and bright wall will appear peeling. Putty powder itself is classified as a semi-finished product. The instability of raw materials is one of the main reasons for the color difference, because the quality of the mineral powder excavated in the mining area will be different due to different regions. .

       Because the supplier uses the method of "refilling the data" to deliver the low-grade materials in a thick and turbid manner, due to the large number of purchases, it is impossible to spot check one by one, resulting in individual "fish that slip through the net" mixed in the production, resulting in individual color differences. The color difference caused by mixing different grades of materials together for production or the color difference caused by scraping different brands of goods on the same wall.

       The color difference is usually not a formula problem, so there is no quality problem. If the wall to be painted can usually be concealed with a paint film, it will not affect the overall decoration effect, such as scraping two or three unpainted walls. If there is a chromatic aberration, it is recommended to scrape another putty powder or paint with no chromatic aberration.

       All personnel involved in production and construction should strictly follow relevant specifications for production and construction to prevent man-made quality problems. If there is a color difference during the construction process, it should be reported to the supplier in time. If there is a color difference during construction, it should be adjusted in time, and the same batch of goods should be scraped to the last one.
