Putty powder must have a national testing basis! Executive standard: Technical standard: JG T3049 This is the ordinary putty powder The water-resistant putty powder is JG T3049N

1. National standard: The national standard is the minimum requirement for the quality of a product, and the national standard for putty powder to be implemented is JG T3049-1998 "Putty for Building Interiors", and the packaging of the standard products is generally marked with the words of the national standard.

2. ISO certification: ISO certification mainly refers to ISO9001-2000 quality system certification, and the quality of products produced by enterprises that have passed ISO certification is the best quality.

Legal basis: Construction Law of the People's Republic of China

Article 3 Construction activities shall ensure the quality and safety of construction projects and conform to the national safety standards for construction projects.

Article 4 The State shall support the development of the construction industry, support the research of building science and technology, improve the level of housing building design, encourage energy conservation and environmental protection, and advocate the use of advanced technology, advanced equipment, advanced technology, new building materials and modern management methods.

Legal analysis: the standard to be implemented for interior wall putty products is "JG T298-2010 "Building Interior Putty"" to meet the standard, through the ISO certification of the quality of the products produced by enterprises, at the same time it should have good hardness, whiteness, fineness, workability, construction performance, environmental protection and other aspects of performance.

Legal basis: Article 11 of the Standardization Law of the People's Republic of China can formulate recommended national standards to meet the technical requirements of basic general, supporting with mandatory national standards, and playing a leading role in relevant industries.

No, if you use low-quality putty powder, the wall will soon peel, crack and peel, even if the surface layer is a high-grade material, the effect may only be mid-range or even below. Hazards of inferior putty powder: 1

Inferior putty powder has poor adhesion, loose material, no moisture or mildew, and is easy to hollow, chalk, crack and fall off after being damp, which seriously affects the decoration effect and is difficult to repair after moving in. 2.Glue must be added to the traditional putty powder processing process, and the glue contains some harmful substances, especially formaldehyde.

The putty powder produced by the regular manufacturers generally meets the national regulations, but the putty powder produced by these counterfeit regular brands is mostly produced in violation of regulations, and the glue content of the putty powder processed by such manufacturers is not scientifically proportional, which can easily cause formaldehyde to exceed the standard. 3.Excessive formaldehyde will not only cause damage to the construction personnel's lungs and lungs, but also cause serious harm to human health if the ventilation is not thorough, and a large number of carcinogens such as formaldehyde will be released indoors, causing serious harm to human health.

At the same time, the unqualified putty powder is large, the cellulose is short or the cellulose content is small, the adhesion is poor, and the outer paint is applied on these putty powder, and it is easy to bulge, crack and even fall off in a short period of time, and the building quality is imitated.
