Floor coating application is a critical project that typically requires careful planning and execution to ensure the final surface quality and durability. Below is a detailed breakdown of the floor coating application steps:

　　01 Preparation
　　Before starting the floor coating application, preparatory work must be completed to ensure the work area is clean, tidy, and free of any obstacles. This preparation includes:
　　1. Cleaning the Floor: Remove all dust, dirt, and debris from the floor surface. Use a vacuum cleaner, broom, and damp cloth to complete this step.
　　2. Repairing Floor Defects: Inspect the floor for cracks, holes, or other damage. If present, repair them to ensure a level surface.
　　3. Remove old floor coatings: If any existing coatings are present, they must be completely stripped to ensure proper adhesion of the new floor coating.
　　4. Check floor moisture content: Use a moisture meter to assess the floor's humidity level. Excessive moisture can compromise coating adhesion, requiring measures to reduce humidity.
　　5. Select appropriate floor coating: Choose the suitable floor coating type based on the construction environment and requirements, such as epoxy floor coating, polyurethane floor coating, etc.
　　02 Primer Application
　　The primer is the first layer in the floor coating system, primarily serving to provide adhesion and seal the floor. Primer application involves the following steps:
　　1. Mix the primer coating: Stir the primer coating according to the manufacturer's instructions to ensure thorough blending.
　　2. Apply the primer coating: Use a roller or brush to evenly spread the primer coating across the floor surface. Ensure complete coverage and a uniform primer layer.
　　3. Allow drying: The primer layer requires sufficient drying time, typically following the specified duration in the coating instructions.

　　03 Intermediate Coat Application (if required)
　　The intermediate coat is usually optional and enhances the durability and aesthetics of the floor coating system. The application steps are as follows:
　　1. Stir the intermediate coat: Stir the intermediate coat to ensure it is thoroughly mixed.
　　2. Apply the intermediate coat: Use appropriate tools to evenly spread the intermediate coat over the floor surface. Ensure the coating fully covers the base coat and forms a uniform intermediate layer.
　　3. Allow drying: The intermediate coat also requires sufficient drying time, typically following the manufacturer's specified duration as indicated on the coating product.
　　04 Topcoat Application
　　The topcoat is the final layer in the floor coating system. It not only protects the floor but also determines its final appearance. Topcoat application involves the following steps:
　　1. Stir the topcoat: Stir the topcoat to ensure thorough mixing. This step is particularly crucial as the topcoat defines the floor's aesthetic appeal.
　　2. Apply the topcoat: Use a roller, brush, or spray gun to evenly apply the topcoat to the floor surface. Ensure the coating fully covers the primer and intermediate coats, forming a uniform finish.
　　3. Allow drying: The topcoat must dry thoroughly to ensure the final floor's durability and gloss.

　　05 Coating Inspection and Repair
　　Once the floor coating application is complete, conduct a coating inspection to ensure quality. During this step, pay attention to the following:
　　1. Check coating uniformity: Inspect whether the coating is even, with no missed spots or drips.
　　2. Check coating gloss: Ensure the coating has appropriate gloss that meets design requirements.
　　3. Inspect coating flatness: Verify the floor surface is level, free of visible defects or blistering.
　　PS:
　　If any coating issues are detected, prompt repairs are necessary. This typically involves recoating affected areas or performing polishing.
