The problem of interior wall paint detection has been troubling everyone. A lot of people have been unable to understand if it is pre-construction or post-construction detection. This order can not be reversed, so whether can it be post-construction detection? The following powder coating powder manufacturer has the answer.
If you need to detect the quality of interior wall paint before construction, you need to carry out sampling detection, if it is the use of the later period that can be detected after construction. Scope of inspection:
1. Check whether the types and tones of commonly used architectural coatings conform to the design scheme and the provisions of the selected test products, and whether they meet the environmental protection standards.
2, engineering acceptance of the interior wall coating should be from the bottom gradually, has not been painted on the need for engineering acceptance again, after painting to engineering acceptance again.
3. When the bottom of the wall is checked and accepted, the wall should be fully dried. The drying time should depend on the actual climatic conditions, and generally should be placed over 10 days.
Quality management of interior wall coating products:
1. The types, models and specifications of commonly used architectural coatings and the functions of architectural coatings need to comply with the requirements of design schemes, standards and construction contracts.
2, architectural coatings commodity certification, in the factory characteristics inspection report must be complete, real, reasonable. 3, the color of architectural paint must meet the requirements of the construction drawing design or user.
Technical quality control of interior wall paint construction:
1. Stipulate that the bottom of batch putty should be cleaned and leveled to ensure no oil stains, no dust and no floating slurry on the surface.
2. Stipulate that the water content of the putty bottom brush is not more than 10% when it is painted.
3, the bottom putty powder should be leveling, firm, strong, no delamination, peeling, crack.
4. Stipulate that the Yangjiao line must be Huakang, smooth and beautiful.
5. The construction of the scraping project should be carried out according to the standard of "the bottom layer paint, the middle and high layer paint, the overall surface paint". The construction of the last scraping and coating raw materials must be carried out after the previous scraping and coating raw materials surface drying; each scraping coating raw materials should be evenly coated, all layers of scraping raw materials must be fused solid, and the surface coating frequency can be improved for projects with special requirements.
6, in the whole process of construction, the construction viscosity of scraping raw materials should be strictly controlled according to the construction method, construction season, environmental humidity, temperature and other standards. There should be full-time personnel according to the instructions to undertake preparation, not arbitrary paint thinner or water.
Interior wall paint must comply with GB18582 "Interior decoration materials interior wall paint harmful substances limit" specifications, can be used as room spraying. When the project is completed, be sure to complete the project acceptance check on indoor air quality in accordance with the provisions of "Code for indoor environmental Pollution Control of civil construction projects".
