Precautions for the Application of Fireproof Paint on Steel Structures: When applying fireproof paint to steel structures, it is essential to ensure that the work is carried out by a qualified and trained professional team. A detailed construction plan should be developed based on the specific engineering requirements and the type of coating being used. Before starting the project, samples of the coating’s physical and chemical properties should be tested according to the specified ratios. For intumescent fireproof coatings, different sections should be tested for their foaming performance during the application process to ensure effectiveness. Before painting, the base material must be thoroughly cleaned to remove any contaminants such as dust, rust, oil, or debris that could interfere with adhesion. Proper rust prevention measures should be taken on the substrate. The primer and top coat must be compatible, and the primer should not cause corrosion on the steel surface. The coating thickness must meet the design specifications, and joints should be reinforced to ensure proper coverage. All aspects of the spraying process—including surface preparation, joint filling, paint mixing, number of coats, quality control, and final inspection—should comply with the national standard "Technical Specifications for Application of Fire Retardant for Steel Structures" (CECS24). During application, the thickness should be regularly measured using a thickness gauge. If cracks appear or the width is excessive, it's important to review the process and check the paint mixing ratio for accuracy. During the spraying process, the consistency of the paint, air compressor pressure, and nozzle distance from the component should be carefully controlled. If splatter occurs, it may indicate improper settings, which need to be adjusted. The amount of diluent added to the paint should not be excessive, as this can reduce the viscosity and prevent proper adhesion to the steel surface. Each layer of coating must be fully dried and cured before applying the next coat. The number of layers, coating thickness, and protective methods should be determined according to the construction design. Each coat should be applied evenly and not too thick to avoid compromising the quality of the finish. It is crucial to follow the correct painting procedures and never compromise on safety to meet deadlines. After the project is completed, the coating thickness should be measured, but visual inspection is also necessary. Check the color, presence of cracks, and leaks. Use a tapping test with a 0.75–1 kg object to assess the coating’s strength, and use a 1-meter ruler to check for flatness. These steps ensure the coating meets both aesthetic and functional standards.
