"Building Finishing Engineering Construction and Acceptance Regulations"  
Since April 1, 2003, the "Regulations for Construction and Acceptance of Building Finishing Projects" approved by the Beijing China Construction Institute of Building Science and Technology and the Housing Industrialization Promotion Center of the Ministry of Construction have been implemented. Coating companies and real estate developers There is a legal basis for litigation for the quality of the wall. The regulations are compiled in accordance with the Ministry of Construction Jianbiao [2000] No. 284, and refer to the relevant provisions of JASS23 "Specifications for Spraying Engineering" and DIN18363 "Building Coating Engineering" as well as Shanghai, Beijing and other regional standards. The Quota Research Institute proposed that the China Academy of Building Research, the central authority for construction engineering standards and technologies of the Ministry of Construction. Some coating companies, including the Beijing Institute of Building Materials Science, the Technical Committee for Standardization of Building Products and Structural Parts, participated in the preparation of this regulation. This regulation is applicable to the construction and acceptance of synthetic resin emulsion interior wall coatings, synthetic resin emulsion exterior wall coatings, synthetic resin emulsion sand wall architectural coatings, solvent-based exterior wall coatings, multi-layer architectural coatings, and exterior wall inorganic architectural coatings. The regulations clearly state that building coating refers to the process of decorating and protecting buildings with coating materials; base layer refers to the surface layer of the coating object, such as concrete, cement mortar, mixed mortar, gypsum board, clay bricks and other materials; undercoating It refers to the coating formed by painting the paint on the base layer; the middle coating refers to the coating between the top coating and the base coating; the top coating refers to the last coating of the coating project; the service life refers to The service life of the finishing material under the premise of meeting the requirements of decoration and protection of buildings. The regulations stipulate that the main technical indicators of synthetic resin emulsion interior wall coatings should meet the requirements of "Synthetic resin emulsion interior wall coatings" GB/T9756; the main technical indicators of synthetic resin emulsion exterior wall coatings should meet the requirements of "Synthetic resin emulsion exterior wall coatings" GB /T9755; The main technical indicators of synthetic resin emulsion sand wall architectural coatings should meet the requirements of JG/T24 of "Synthetic resin emulsion sand wall architectural coatings"; the main technical indicators of solvent-based exterior wall coatings should meet the requirements of "Solvent-based exterior wall coatings" 》GB9757; The main technical indicators of multi-layer architectural coatings should meet the requirements of "Multi-layer architectural coatings" GB9779; the main technical indicators of exterior wall inorganic architectural coatings should meet the requirements of "Exterior inorganic architectural coatings" JG/T26. The regulations require that the coatings and semi-finished products used in architectural finishing, including the materials prepared at the finishing site, should have the product name, implementation standard, type, color, production date, shelf life, production company address, instructions for use and product qualification certificate, and have a production company The quality guarantee certificate must be accepted by the construction unit before it can be used. The service life of the external wall shall not be less than 5 years. The putty and back cover material used in architectural finishing must be compatible with the performance of the selected finishing paint. The main technical indicators of the interior wall putty should meet the requirements of "Building Indoor Putty" JG/T3049 and "Environmental Labeling Product Technical Requirements for Waterborne Coatings" HJBZ04 It is stipulated that the strength of exterior wall putty should meet the requirements of "Multilayer Architectural Coatings" GB/T9779, and it is not easy to crack. The regulations require that when the coating maintenance period of the coating project expires, the construction drawings, design instructions and other design documents of the coating project should be checked; the product qualification certificate, performance test report and re-inspection record of the materials used in the coating project; matrix ( (Or grassroots) inspection records; concealed project acceptance records; construction self-inspection records and other relevant materials. At the same time, it is required that the finishing projects of all types of buildings must carry out the data acceptance of the base coat, middle coat and top coat according to the requirements of the product manual and the construction plan.
