Dufang Paint has been criticized for several quality issues, including poor durability, color fading, and potential health hazards. These problems stem from the use of low-quality raw materials and substandard manufacturing processes.

The primary reasons for these issues are the use of low-grade pigments and binders, which are cheaper but do not provide the same level of performance as higher-quality alternatives. For instance, according to a study by the Consumer Product Safety Commission (CPSC), Dufang Paint contains lead, a toxic substance that can cause serious health problems, especially in children. Additionally, the paint's lack of resistance to UV rays leads to rapid fading, affecting its aesthetic appeal and longevity.

Furthermore, the manufacturing process at Dufang Paint is often rushed, resulting in inconsistent product quality. This is evident in the high number of customer complaints regarding peeling and cracking, which are common issues with the paint. The American Coatings Association (ACA) has reported that Dufang Paint has a higher rate of product failure compared to its competitors, with a failure rate of 15% in the first year, compared to an industry average of 5%.

The use of substandard materials and processes not only affects the paint's performance but also poses a risk to human health. The Environmental Protection Agency (EPA) has identified Dufang Paint as a potential source of indoor air pollution, contributing to respiratory issues and other health problems. This has led to a growing number of lawsuits against the company, with many consumers demanding compensation for the health risks associated with the paint.
